Moulds can quickly ruin your plants during the last weeks of the flowering stage, that’s why many growers choose mould resistant cannabis strains to guarantee success. This type of genetics are resistant to high relative humidity levels, rarely developing moulds like botrytis or powdery mildew even if grown in humid climates.

If you checked the link above, you may have seen a wide rage of mould resistant varieties. Still, we want to make your decision easier for you by listing some of our favourites, genetics that – for one reason or another – have captivated us for their excellent results in humid climates. Let’s see them now!

Harvest time is coming!

Viper City OG XIII by Moxie Seeds

Pakistan Chitral Kush, Grape Ape, Grandaddy Purple, Serious Six, Peyote Purple, Panama Red…all of these cannabis strains show a wonderful colour palette which goes from reddish to purple. Indeed, and while the most common colour in cannabis is green, both leaves and buds may turn orange, pink, purple, black, red, blue…These awesome colours are often one of the traits that breeders want to fix, since it is also one of the most demanded traits by users. 93% of cannabis smokers have noted that they’ve been influenced by the colour of the strain sometime. But, how does cannabis develop such beautiful shades?

A colourful indoor cannabis garden

Natural pigments

When we think about plants, the first colour that comes to mind is green. Indeed, the world of plants id dominated by the green colour, but if we take a closer look we’ll soon realize that plants can also develop many other colours, which is explained by pigments. Pigments are chemical colorants, either from living organisms or synthetic. In cannabis plants, they’re are normally divided into several categories:

Chlorophyll

Chlorophyll is quite abundant in plant cells, representing around 70% of the pigments contained in one plant. It is responsible for the green colour and essential for the plants life, since it allows them to absorb the necessary …

The use of humic and fulvic acids is becoming increasingly popular among all types of cannabis farmers, who can now take advantage of a healthy, rich and living soil that produces happy plants and therefore abundant harvests. Thanks to this substances, nutrient uptake and management are much more efficient, and root growth is simply spectacular.

Either if you’re using organic soil or hydroponic systems, using  humic and fulvic acids is a very easy way to ensure the best possible conditions for the roots of your plants. Indeed, it is especially recommended in hydroponic cultivation since these types of growing media do not contain nutrients nor microbial life. In this way, you get the most out of the nutrient solution that you’ve carefully prepared for your plants.

Quality soil produces quality flowers

Soil organic matter

Soil is composed by many substances, some of them resulting from a transformation process of certain molecules. Among the organic components of soil, we can find living organisms on the one hand and organic matter on the other, which usually comes from chemical and microbial transformation processes of organic wastes contained in the soil.

In turn, we can divide this organic matter into unaltered material (fresh, not processed or modified) and altered material (sometimes called humus), which are byproducts physically and chemically different from …

Alchimia Grow Shop have recently introduced a new and interesting product, 100% legal cannabis buds with CBD. The THC content (<0,2%) of this flowers is far below the legal limit, while CBD content is up to 8%, so they’re especially aimed at those who want to benefit from the medicinal properties of CBD – and other non-psychoactive cannabinoids and terpenes – without getting “high”.

We invite you now to take a closer look at these new products and know more about their main characteristics.

Hemp cultivation is recovering its former importance

Legal cannabis buds?

Indeed, and as we already mentioned, THC levels in these buds are below the legal limit, thus being officially classified as “hemp”. Thus, you can freely – and legally – purchase and use these flowers in most countries where “marijuana” is illegal (that is to say, cannabis with high THC content). What is then the difference between this new product and the hemp flowers which have been already available for some time? Well, the main difference here – apart from growing techniques – is the genetics used to produce this buds, far superior from traditional hemp varieties.

Cannabinoid content of Orange Star

Despite most hemp strains contain considerable amounts of CBD and almost no THC, many of them have unpleasant scent and taste. In this …

We’ve recently added a new Spanish bank to our feminised seed catalogue, a bank that, despite its young age (it was founded in 2017), has already aroused enormous interest among cannabis growers and users. We’re talking about BSF Seeds, short for Bigger, Stronger and Faster that perfectly sums up the philosophy of this team of breeders when it comes to developing the cannabis varieties they offer. In this article we’ll familiarise you with this seed bank and its work.

BSF Seeds: Bigger, Stronger, Faster

The BSF Seeds catalogue is made up of both feminized and large size automatic varieties (also feminized), making them hugely popular with fans of auto varieties. As well as including some classics of the cannabis scene, the catalogue also gathers together some of the most coveted current hybrids of the moment, like Gorilla Glue, Tangie or the famous Zkittlez.

The breeding program followed by BSF is clear: select the most resistant, productive and fastest specimens to stabilise and fix these traits to obtain hybrids that are especially easy to grow and give excellent results, whether they are autoflowering seeds or photodependent varieties. If we factor in the high quality of the genetics from which they start their work, the formula for success seems assured! Furthermore, they’ve also used a very original formula to manage …

Ganja, Collie, Kiki, Sinsemilla…cannabis has plenty of different names, especially in Jamaica, a small Caribbean island known around the world for its long relationship with this plant.

Indeed, Jamaica is a true place of reference with regard to cannabis cultivation for smokers worldwide. Its tropical climate and fertile soil are ideal for the cultivation of cannabis plants, especially Sativas. Moreover, it is also the place where the Rastafari movement was born, which promotes a religious use of ganja and has a large number of followers in the island. Still, the use of cannabis is widely spread among all social classes – not only Rastafarians – and is doubtless one of the most popular crops in the island. In this article we’ll tell you more about the relation of cannabis with this small Caribbean paradise.

7-mile Beach, Jamaica

Introduction of cannabis in Jamaica

Being British colony until 1962, Jamaica is a traditional producer of sugar, also cotton during the slavery period. The indigenous people from the island – the Arawak tribe – were exterminated before the arrival of the British by the Spanish colonizers, while the Commonwealth government forced thousands of slaves to move from Western Africa to Jamaica to work on plantations.

After the abolition of slavery in 1838, and while many slaves abandoned their …

If we have a look at all the different pieces of equipment we need to set up an indoor cannabis grow, we can see that they fall into one of several categories according to the role they play in the grow tent: Illumination, ventilation, humidity control and heating are the main elements responsible for recreating as close as possible the natural cycles and ideal conditions for plant growth. The proper control and adjustment of these elements is crucial to achieving a great final result, with a healthy yield of the highest quality flowers.

Over time, various electronic devices designed to control the climate in cannabis grows have appeared on the market, these devices connect and coordinate all the elements required to recreate sunlight and climate, making it possible to program photoperiods, control air intake and extraction, and regulate temperature, humidity and pressure.

The grow space climate must be optimised to create the ideal environment for plant development.

A climate controller can save the grower a great deal of work, in addition to optimising electricity consumption. The effectiveness of a climate controller relies upon the sensors used to control and record the variations in temperature, humidity or air circulation inside the interior culture room.

Among the climate controllers that you can find in Alchimiaweb.com, here we’d like …

The energizing effect of some cannabis strains is, without a doubt, a true favourite among many users. This uplifting feeling – often called “high” – is often associated to Sativa genetics with high THC content, although other plants with different cannabinoid ratios can provide a very pleasant, social and creative effect.

For this reason, and within the myriad of feminised seeds available on the market, we have selected 7 marijuana strains that will increase your creativity and social side, improve your mood and motivate you to perform daily activities. We hope you’ll enjoy their vibrant energy!

Sativa plants are known for their uplifting effect

Easy Haze by Philosopher Seeds

Easy Haze is one of the strains included in Philosopher Seeds Classic Line. Coming from a Special K backcross, her euphoric and almost psychedelic effect is ideal to listen to music or enjoy outdoor activities. She is used by many users to improve mood and induce a very pleasant feeling of full happiness.

She grows vigorous but with compact structure, traits inherited from the Yumbolt parent. On the other hand, the Kalimist parent provides its unique incensed and woody scent and intense Sativa effect. Yields are awesome, while THC content can reach 21%.

In this series of posts we’re taking a comprehensive look at a range of techniques used by growers to shape cannabis plants and facilitate cultivation. Pruning and training are essential tools to control the way our plants grow, whether to restrict height, maximise yields or as a management tool for the indoor cultivator trying to control multiple varieties in one grow space.

Pruning plants is a great way to maximise flower sites

When discussing these techniques, we can essentially split them into two basic types of method:

• Destructive pruning methods that effect some kind of damage on the plant, like pinching out, FIM, super-cropping etc.
• Non-destructive training techniques designed to minimise damage, such as LST (Low Stress Training), SCROG, etc.

Choosing between pruning or training as a method to control your plants is largely a matter of personal preference. Many gardeners dislike the “destructive” methods, which effectively damage the plant as part of the process, provoking a certain amount of stress and creating potential entry points for infection in the wounds left behind. For this reason some growers prefer to use non-destructive methods of bending and tying-down to control height and shape plants, an approach known as LST or Low Stress Training, which we examine in detail in another post. In this article we’re going to concentrate on …

What is CBG?

• Name: Cannabigerol
• Formula: C21H32O2
• IUPAC name: 2-[(2E)-3,7-dimethylocta-2,6-dienyl]-5-pentylbenzene-1,3-diol
• Molecular mass: 316,48 g/mol
• Boiling point: Not available
• Apearance: White powder/crystals

Discovered by Gaoni and Mechoulam in 1964, CBG or cannabigerol is one of the cannabinoids exclusively produced by the cannabis plant, which is stored in the trichome heads with the rest of cannabinoids and terpenes. While the CBG content in most plants is often low or very low – in most cases lower than 1% – this particular compound is crucial for cannabinoid synthesis, as we have known for the past 4 decades ( (Shoyama, Yagi and Nishioka, Phytochemistry Journal, October 1975). As a general rule, hemp contains higher amounts of CBG than commercial, narcotic cannabis strains.

CBG is a non-psychoactive phytocannabinoid, which means it is produced by plants and does not “get you high”. It is believed that it has multiple medicinal properties which can be used to treat different conditions, and is also precursor – its acid form, to be exact – to the main cannabinoids (THCA, CBDA, CBCA) secreted in the trichome heads, which in turn explains the low percentage of CBG found in mature plants when compared to their THC or CBD content.

The history of this North American cannabis seed company Brothers Grimm is quite uncommon, especially if we take into account the huge success of their strains since they were first introduced in the market in 1996. Indeed, and before their withdrawal from the seed market in 2002, some of their genetics had already become true classics in the cannabis scene, with names that will surely sound familiar to you: Cinderella 99, Apollo 13, Killer Queen or Rosetta Stone just to name a few. Over time, this varieties have also become the baselines for many other hybrids from breeders across the globe.

Brothers Grimm Seeds, living history of cannabis breeding

The number of awards won by both Brothers Grimm Seeds varieties and other strains developed from their genetics is simply astounding. But, how did it all started? Let’s take a look now at the origins of this company, their flagship genetics and, of course, the exclusive interview with MrSoul!

Origins of Brothers Grimm Seeds

It all started when MrSoul – one of the founders of the company – contacted the dutch seed bank Super Sativa Seed Club in 1987. Soon after, he was already distributing their seeds throughout the American territory. The access to new and amazing genetics, as well as his knowledge on engineering (he had studied nuclear engineering …

The use of medical cannabis to treat ailments and the symptoms of a large number of diseases is becoming increasingly common, as are the many users who testify to its effectiveness compared to the so-called “synthetic drugs”. While sometimes the use pharmaceutical medicines may be essential, we are increasingly more aware of the medicinal properties of cannabinoids and terpenes and how to use them, either to alleviate the symptoms caused by the disease itself, or to mitigate possible adverse effects of medications or treatments.

One condition for which cannabis seems to be of great help is endometriosis, a chronic disease estimated to affect more than 170 million women worldwide, and one that in many cases goes undiagnosed. This past March was the Endometriosis Awareness Month, a global initiative aiming to raise awareness of this problem and encourage governments and organisations to actively fight against this disease.

Cannabis can alleviate many of the symptoms of endometriosis

What is endometriosis?

As we saw in our article on cannabis and menstruation, each month women lose endometrial tissue during their period, the tissue that normally envelops the uterus. Endometriosis is a gynaecological disease in which said tissue (endometrium) also grows in other internal areas of the body such as the ovaries, fallopian tubes or intestines. We can define it as …

What is the entourage effect?

The so-called entourage effect (sometimes referred to as the ensemble effect) is a term used for the first time in a study on the interaction between various compounds present in cannabis, published in the July 1998 issue of the European Journal of Pharmacology. This text (An entourage effect: inactive endogenous fatty acid glycerol esters enhance 2-arachidonoyl-glycerol cannabinoid activity) was written by researchers and scientists including Professor Raphael Mechoulam and Shimon Ben-Shabat among others, and demonstrates the increase in activity of a given cannabinoid thanks to the presence of another compound, in this case the esters of a fatty acid. However, as research has progressed over the years, this term has been coined to refer to the interaction, or synergy between the various cannabinoids, terpenes and flavonoids present in the plant that define the effects of cannabis.

Cannabinoids, terpenes and other compounds act in synergy (Photo: Don Goofy )

In short, and as we will see in more detail below, it is a principle whereby the association between the different compounds present in cannabis can enhance (or mitigate) the effect of each one of them, in many cases improving the results given when administering isolated cannabinoids. A classic example of this is found in the potentiation of the effects of phytocannabinoids when THC and …

Although here in Europe the use of water pipes is not as widespread as in the United States, there are a growing number of smokers who prefer to consume their weed or concentrates through what is commonly called a bong. It can be easy for newcomers to the world of water pipes to become dazzled and confused by the vocabulary and terms used to describe water pipe accessories and their characteristics.

In this article we present a comprehensive guide to help beginners understand all about bongs and bubblers, their principal features and also the main accessories available to add to your water pipe.

Bubbler, Heady Glass

Bubblers, rigs, bongs… these are just some terms used for the different water pipes available for the consumption of cannabis, whether in the form of flowers or as concentrates. Let’s take a look at some fundamental points to consider when buying a water pipe or accessories for a bubbler.

Connections, male or female?

Most glass pipes have at least one joint or connection to fit a bowl or the nail into.

These joints come in different diameters but generally they will be either 14mm or 18mm connections (although increasingly 10mm joints are used for dab rigs/oil bubblers). These connections are available in two different styles, either male or female, and it’s …

EC meters are a very useful tool when growing cannabis since they allow growers to have full control over the nutrition of their plants. Today, with tens of nutrient brands offering their own formulations, it may be difficult to find the correct dosage for your plants, especially when nutrients or additives of different brands are mixed. Well, with the help of an EC meter you can easily check the exact amount of nutrients contained in your nutrient solution, which, as you’ll see in this article, makes things a lot easier.

Using pH and EC meters is recommended to achieve best results

EC meters are electronic devices which can either operate on batteries (portable models) or directly plugged into the mains (continuous meters). They measure the electrical conductivity of fluids, that is to say, the amount of salts dissolved in the water (the material’s capacity to conduct electric current). In this way, conductivity levels tell you the amount of salts (nutrients) contained in your nutrient solution.

Cannabis plants require a varying nutrition according to their growth stage. With the help of an EC meter, and especially in the case of hydroponic cultivation (coco coir, clay pebbles, deep water culture, etc), you can easily check the amount of nutrients and thus give your plants the correct nutrition.

5 autoflowering strains that will surprise you

The quality of autoflowering (also known as automatic or simply auto) genetics have been greatly improved over the past years. Today, cannabis breeders develop top quality auto versions of some of the most acclaimed photoperiod varieties, so this type of genetics is being increasingly used by many growers.

Auto strains are ideal for those with small growing spaces, to make several outdoor crops per year easily or for those who have an outdoor growing space with light pollution (which can make it impossible to grow photoperiod strains). While just a few years ago the quality of these strains was mediocre, today you can find literally hundreds of autoflowering strains coming from the best genetics on the market.

We want to make things easy for you, that’s why today we present you a list of 5 extraordinary auto varieties that you should definitely try if you’re interested in this useful type of cannabis plants. New and classic strains, CBD-rich plants, high yielding genetics…you’ll find whatever you’re looking for!

As research on the different cannabinoids and terpenes  – and other compounds produced by the cannabis plant – advances, more and more testimonies claim that the efficacy of these substances is beyond doubt. While further research is needed in both humans and animals,  cannabinoids like CBD are being increasingly used to treat diverse symptoms and pains in pets, since many users have realised the great benefits it can provide in some cases.

Cannabis can help our pets to have a healthier life

The endocannabinoid system of animals

Mammals, as our beloved dogs and cats, all have an endocannabinoid system composed of CB-1 and CB-2 receptors, which also produces endocannabinoids. When they detect the presence of other cannabinoids in the body, these receptors react in much the same way as they do in the case of humans, so it is believed that cannabinoids and terpenes could provide similar benefits in animals. While the CB-1 receptor is focused on the activity of the brain and central nervous system (CNS), the CB-2 receptor is mainly found in peripheral organs like the immune system. The most important here is that phytocannabinoids (cannabinoids produced by plants) activate these receptors, providing a number of beneficial effects.

However, and before starting any cannabis-based treatment, we must stress that psychoactive cannabinoids like THC or tetrahydrocannabinol have …

Cannabis plants go through different stages of life before reaching harvest. These stages are: germination, pre-growth, growth and flowering. Depending on the phase of life, the care and feeding required can vary greatly, in this case we’re going to focus on the flowering period of cannabis and the changing nutritional demands upon our plants.

Phases of plant life

Pre-bloom phase of cannabis after the photoperiod change

At this point in their life cycle the plants are growing well, they’ve already occupied a little over half of the available space, and now is the moment to change the timer, so instead of using 18/6 we will switch to a 12/12 photoperiod and induce the plants to flower.

Depending on the type of plant and the genetics being cultivated, the time between changing the photoperiod to 12/12 displaying the first flowers can vary a great deal, and more if we are talking about differences between pure Indicas and Sativas.

Indica vs sativa

The stage between switching the photoperiod to 12/12 and seeing the first flowers appear is known as “the stretch“, as plants will tend to elongate and stretch in growth at this time. There’s a huge difference between the stretch of an indica plant and that of a sativa.

Indica plants stretch far less …

What is the Emerald Triangle?

The Emerald Triangle refers to an area located on the northwest coast of the United States (northern California) and comprised of Mendocino, Humboldt and Trinity counties. To be delve into the origins and traditions of cannabis cultivation in this region, we must go back to the 60s, during the Summer of Love in San Francisco. During the second half of the decade, and with the hippie counterculture as a backdrop, a good number of growers settled in this area in search of a place that would meet the ideal conditions for the outdoor cultivation of cannabis, namely isolation and a privileged climate. Since then, the Emerald Triangle has been one of the main sources of cannabis supplying California. As of 1996, and after the approval of California’s Proposition 215 for medical cannabis, the production in these three counties shot up due to the increase in demand, reaffirming the Emerald Triangle as one of the main producing areas of the country.

What are Solvent Extracts?

Whereas all solventless concentrates are extracted via mechanical means, be it agitation or heat and pressure, we can also make cannabis concentrates with a wide range of chemical and organic solvents, most commonly butane, propane, ethanol and CO2. This process works by dissolving the trichome heads in the liquid solvent which is separated from the plant material and purged (evaporated off) in a vacuum oven or dessicator and vacuum pump to ensure we are left with a pure resin extract with as little residual solvent as possible. Solvents are divided into two groups, polar and non-polar, with non-polar solvents like butane readily dissolving non-polar compounds from the plant, in this case the oils and lipids making up the trichome heads. Polar solvents like Ethanol however will extract both non-polar and polar compounds, meaning water-soluble compounds like chlorophyll are more likely be extracted alongside cannabinoids and terpenes. Many of the solvents used in extractions are highly flammable, meaning only the proper equipment should be used to extract and purge, and additionally a high level of safety and care must be taken to avoid accidents at all stages of the process.

The story of this group of growers begins around 2003, when the world of medicinal cannabis in France was very small. At that time, deep within the cannabis culture underground, there were a few enlightened souls beginning to forge a therapeutic path in the French cannabis world. From among these few select characters swimming against the stream, the MaD Strains collective was formed, the Hip Hop Bee of cannabis!

Through passion and hard work MaD Strains (Medicinal And Delicate Strains) learnt and evolved in their growing, both outdoor and indoors, building a background knowledge that they never hesitated to share with the rest of the cannabis community.

In 2006, after 3 years of work and many internet contacts, they were invited to a French underground growers forum. There they made contact with the cognoscente of the underground cannabis world, presenting and sharing their first elite clone, obtained from an Exodus UK Cheese.

In that encounter a series of synergies between growers was generated that in 2007 led to a clone of Amnesia Core Cut arriving in their hands, and another of the Riri Cut of Sour Diesel, little could they imagine at that moment the repercussion that this clone would have in the future. From there, they learnt the importance of conserving and exchanging genetics.

Every year in the weeks around Spannabis, the Catalonian city of Barcelona plays host to a multitude of events, competitions, workshops and seminars as the great and good of the global cannabis scene flock to the city to enjoy the company of like-minded folk from around the world. This year one of the biggest events of off-Spannabis was the Masters of Rosin competition organised by one of the top clubs in the city HQ Barcelona and hosted by solventless pioneer Nikka T of Colorado’s Essential Extracts.

Masters of Rosin 2018

First edition of Masters of Rosin Barcelona

This was a different proposition from the usual cannabis cups, for one thing it was the first ever Rosin-only competition, and for another thing it was judged exclusively by professionals from the cannabis sector, picked for their expertise in this relatively new solvent less extraction technique called rosin. In this first edition of the contest the judges panel was comprised of such big names as DNA Genetics, House of the Great Gardener, Frenchy Cannoli, Ripper Seeds, R Kiem Seeds, Dabinator, Sasquash, La Kalada, Yellow Brick Labs, and Nikka T himself, as well as one very fortunate member of the team here at Alchimia.

Bhang Lassi is a very popular drink in India both for its aromatic smell and relaxing, spiritual effect. It is an ancient cannabis preparation enriched with seeds, spices, honey and milk which has been used for centuries in this amaing country. In this article we explain you how to easily prepare it at home!

Bhang Lassi and cannabis

The popularity of this beverage has its origins in the Hindu religion and is associated with the cult of Shiva: the followers of this goddess used – and still use today – to smoke Bhang (which means “cannabis” in Hindi language) in the temples dedicated to Shiva, also charas (which is hashish obtained by rubbing fresh plants with the hands). Without a doubt, sadhus are the most famous among the followers of Shiva, religious “holy men” who wander along the temples with their traditional clay chillums.

Bhang Lassi and other cannabis derivatives have been traditionally used in religious ceremonies to connect men with Shiva and be purified from their sins. But the popularity of Bhang Lassi skyrocketed when the first tourists interested in recreational cannabis visited India (during the 70’s and onwards) and discovered the traditional cannabis milk shakes, which is to say, Bhang Lassi.

Since the popularity of this drink throughout the territory is huge, you can find …

When we talk about Sativa strains, there is a name that comes to mind almost immediately: Jack Herer. This genetics is doubtless one of the most renowned and sought-after cannabis hybrids around the world, winner of countless awards and a true classic in Amsterdam coffee shops. Obviously, it has been used to develop many other new strains, as the spectacular Rosetta Stone, one of the parents of the strain we’ll see today.

In this occasion we’ll know more about one of te best Sativas of Spanish seed bank R-Kiem Seeds, Eli, a variety which comes from the cross between the aforementioned Rosetta Stone and a pure African landrace kept by the guys at R-Kiem, Sawla Ghana.

Genetics of Eli by R-Kiem Seeds

Rosetta Stone – the male parent used to create Eli – comes from a hybrid developed in the late 90s by Brothers Grimm Seeds, a cross between Ginger-Ale and the famous White Widow. On its part, Ginger-Ale is basically composed of Jack Herer genes (Cafe Girl, Cinderella and Princess). Thus, Rosetta Stone stands out for her unique woody scent – with awesome turpentine and sawdust notes – and intense and balanced effect. Her growth pattern is more compact than most Sativas, developing a prominent main stem where …

The XV edition of The Cannabis Fair (as Spannabis is also known) includes a new pavilion to host more exhibitors and increase the global surface of the fair, something necessary if we take into account the large number of professionals who want their space in this event. In this way, this year’s edition will count with 22 new exhibitors for a total of 258 companies.

As could not be otherwise, Alchimia Grow Shop will be there sharing our booth with our brothers from Philosopher Seeds and Reggae Seeds. Fun and lots of laughs are ensured!  As always, we’ll be in the central …

Today, we have thounsands of cannabis strains with tens of different traits, so that virtually any type of grower can easily find what he’s looking for. Today we’ll focus on strains with fruity flavour, like oranges, lemons, strawberries or blueberries. Thus, in this article we’ll list some of the best and most reputed fruity cannabis strains, which have a terpene profile (terpenes are aromatic molecules which give marijuana its particular scent and taste) reminiscent of these fruits.

Cannabis strains with citrus flavour

Citrus flavour, which is present in some local strains from Asia or South America, comes from a terpene called limonene. Highly appreciated by many users, these strains have been bred to fix this trait and even enrich it, so we can now find diverse genetic lines with complex citrus scent, each of them with its own nuances and personality. In this way, Las Vegas Lemon Skunk has favored the appearance of many other strains with citrus aroma, like Super Lemon OG, Lemon OG Candy, Lemon Walker…

However, and depending on concentrations and interactions with other terpenes, another limonene isomer can also produce a scent more similar to oranges or mandarins. Without a doubt, Orange Bud – a particularly smelly Skunk phenotype which became …

Until recently, it was very difficult to find professional quality extractions without investing several thousand euros in a complex closed circuit system.

Herborizer offers one of the most interesting alternatives with this Passive Mini Closed Loop system. Closed circuit systems permit us to obtain better quality oils thanks to the purification of the gas (which we will discuss next) but also permits the almost infinite reuse of this refined gas.

Finally BHO lovers can try professional quality extractions thanks to this Mini Closed Loop by Herborizer. Compact in size, the tube measures 15cm in length by 4cm wide and the containers of the system measure 10cm x 10cm, being very easy to transport and particularly resistant thanks to its integral fabrication of 304 stainless steel. With a capacity of 45 grams of flower and approximately 400-500ml of butane gas, with this system it will be possible to recover between 4 and 7 grams of BHO in each session.

We have been able to make various extractions with different plants

Above all, never forget that this type of extraction is potentially dangerous if the proper security measures are not respected. Although this is a closed circuit, it is always vital to carry out the extraction outdoors, in a well ventilated place.

Genetics of Clementine Kush by Colorado Seed

This hybrid, which we already saw in our presentation of Colorado Seed, comes from a cross between he renowned Tangerine Sunrise and Gupta Kush, from which the best individual was used to develop the feminised version or S1.

Tangerine Sunrise is a cross between a spectacular Sativa from Hawaii – Hawaiian Sunrise – and Tangenesia, a hybrid between Tangerine Haze and (Ghiesel x Amnesia Haze). The resulting strain has intense orange scent with delicious Haze and musky notes, highly appreciated by connosseurs from Colorado also thanks to its positive, euphoric effect.

On the other hand, Gupta Kush is a second generation backcross between Ghost OG Moonshine and Rugburn OG. It’s a mostly Indica strain created by Colorado Seed to honour Dr. Sanjay Gupta with potent sedative effect and suitable to treat anxiety, stress or insomnia. It performs …

Cannabis plants have a remarkable capacity to adapt to the environment they grow in, a great advantage for us growers as it frees us to select the type of substrate best suited to our needs from the wide range available on the market that serve perfectly as growing media for cannabis.

In this post we will look at the different substrates and the variants of each of them, highlighting the fertilisers to be used and the peculiarities of each substrate, enabling you to choose the one that best suits your needs, whether it is for ease, production, quality , or simply because you want to innovate or try new cultivation techniques.

Cannabis and substrates

Soil as a substrate for cannabis

Soil is the universal substrate used for all vegetation, the most widely used growing medium since the invention of agriculture. We can describe what we call soil as a composite of different types of substrates. The native soil out in the fields may be suitable for cultivating certain types of plants but not for others. Likewise, not all soils work for cannabis cultivation, they must have structure, composition and characteristics suitable for this use.

We must highlight the essential characteristics that the soil must have so that the cannabis plants have an optimal, problem-free development. If that’s not …

Nowadays more and more people are being made aware of the benefits of consuming cannabis resin extracts or concentrates, they are more efficient, with higher purity and potency, they have better flavour and give relief more quickly than smoking or vaping flowers. Indeed, in California, cannabis flowers currently make up just over half of the market (55% in the 2nd quarter of 2017.), with extracts making up the remaining 45%, and according to figures from Colorado, another beacon of legalisation in the US, the concentrate market is growing at an astounding rate, with sales increasing by 125% from 2015 to 2016, compared to an 11% rise in flower sales and an 53% rise in edibles.

Solvent, Non-solvent, Solventless and Solvent-free. What’s the difference?

These terms are increasingly common to see in the menu in dispensaries or cannabis clubs, but they can cause some confusion, so let’s examine the real meaning behind them within the context of the cannabis world. Solvent extracts are those that are carried out using a (generally hydrocarbon like purified butane gas) solvent to dissolve the active ingredients and separate them from the plant material. Solventless or non-solvent is a label applied to products that have been extracted mechanically, without the use of solvents. Now, here’s …

Feeding the soil

The nutrition of cannabis plants is a key factor that to a huge extent will determine the success of the harvest. Naturally, achieving a high yield of flowers is one of the principal objectives of every gardener, and a good way to measure the success of the grow. As a result the use of fertilisers in cannabis cultivation is pretty much ubiquitous, although there are still many growers unaware of the benefits of a healthy and active microbial life in the substrate.

To faithfully reproduce and accentuate the organoleptic characteristics (the aromas and flavours) of the cultivated variety, and to achieve a high cannabinoid content in the trichomes, are good indicators of a successful cannabis grow, and to achieve this, proper nutrition is absolutely indispensable.

All growing media needs microbial life for healthy plant development

Therefore, the type of fertiliser that we use, in addition to encouraging flower production, will also have a significant influence other aspects such as the quality and final aroma of the flowers, their cannabinoid content and even the speed of flowering and maturity.

It has been demonstrated that when cultivating cannabis with natural or organic fertilisers instead of chemical or mineral fertilisers (minerals) the plants will produce better quality buds, giving excellent results in terms of flavour and aroma as …

Cannabis concentrate consumers are increasingly numerous thanks to the advances in equipment available on the market allowing the production of good quality homemade cannabis resin extractions. Here, fans of Rosin or BHO can find various different methods to consume their extracts.

Spread on rolling paper (Twax Joint)

One of the simplest and probably one of the oldest methods, in the 70’s, consumers of honey oil made with alcohol would smoke it by smearing some onto a cigarette.

Now in 2018 consumer habits have evolved somewhat. The Twax Joint has become famous across instagram and it’s frequent to see increasingly complex and highly decorative spliffs covered with various different types of cannabis oil, it seems there are no limits to the creativity and imagination of cannabis users.

When consuming this type of joint, we should take some care not let the oil drip off and fall to the ground, we will have to hold the joint in an upright position to ensure the oil flows onto the paper.

On a vaporiser screen

Some vaporisers such as the Volcano or the Firefly allow us, thanks to a specialised screen, to vaporise BHO or Rosin type cannabis oils of high purity. The flavours are preserved perfectly and we obtain the same benefits as in the vaporisation …
