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!

Dogs, cats and CBD: Cannabis and pets

, , No Comment

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 …

Flowering in Cannabis plants

, , No Comment

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.

Plant life cycle

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 compared to Sativa

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.

The Emerald Triangle: Californian Cannabis & Tradition

, , No Comment

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.

Complete Guide to Solvent Cannabis Extracts

, , No Comment

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.

Introducing MaD Strains: Medicinal and Delicate

, , No Comment

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.

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

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 …

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.

OG Kush x Blueberry hybrid with berry scent

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 …

BHO Extraction with Herborizer Mini Closed Loop System – OK

, , No Comment

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.

A range of BHO extractions

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.

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 …

Products to enhance microbial soil life

, , No Comment

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 substrates can benefit from microbes

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 …

How to Consume Cannabis Concentrates

, , No Comment

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.

Pinene: A terpene that can improve your memory

, , No Comment

What is Pinene?

  • Name: Pinene, alpha-pinene, beta-pinene
  • Formula: C10 H16
  • IUPAC name: (1S,5S)-2,6,6-trimethylbicyclo[3.1.1]hept-2-ene
  • Molar mass: 136.24 g/mol
  • Boiling point: 155-156ºC
  • Appearance at room temperature: Liquid, almost insoluble in water

Pinene is a bicyclic monoterpene widely found in the resin of many plant species, from conifers (pine trees, spruces) to non-conifer plants like wormwood, rosemary, sage, heterotheca or cannabis. Two isomers are found in Nature, called alpha-pinene (α-pinene) and beta-pinene (β-pinene), which can be found in substances like pine resin, turpentine or camphene and are also used by many insects to communicate. Pinene is also a common terpene in a large number of cannabis strains, being highly appreciated by many users for its beneficial properties.

Molecule of alpha-pinene

Molecule of alpha-pinene

Indeed, many cannabis varieties contain considerable amounts of pinene in their trichomes, a terpene that – as we’ll se next – has numerous therapeutic properties (especially the α-pinene isomer). Furthermore, pinene is also widely used in the industry (selective catalytic oxidation of pinene produces compounds used to make cosmetics and fragances), while the beta isomer is used to synthesize myrcene, one of the most popular terpenes.

7 fast flowering cannabis strains

, , No Comment

Sometimes, you may not be sure about which cannabis strains to purchase for your next grow. Your personal taste and circumstances will greatly determine your decision, so while some of you may be looking for high yields or certain effect, others may prefer strains resistant to moulds or with the shortest possible flowering period.

In many occasions, the path followed by breeders to develop their genetics is similar, looking to fix certain traits in the offspring. Thus, today we’ll present a list of strains known for their early flowering trait. As you’ll see next, all varieties listed here have a bloom period no longer than 8 weeks, something that – on the other hand – doesn’t question their quality at all.

Cannabicyclol (CBL) – A cannabinoid in need of investigation

, , No Comment

What is Cannabicyclol?

  • Name: Cannabicyclol
  • Formula: C21 H30 O2
  • IUPAC Name: (1aR- (1a alpha, 3a alpha, 8b alpha, 8c alpha)) – 1a, 2, 3, 3a, 8b, 8c-hexahydro-1,1,3a-trimethyl-6-pentyl-1H- 4-oxabenzo (f) cyclobut (cd) inden-8-ol
  • Molar mass: 314.469 g/mol

Cannabicyclol, also called CBL, is one of the least known and studied cannabinoids in the cannabis plant. Although it is commonly found in many varieties, in particular those with a higher content of CBC (Cannabichromene), the amount of CBL produced in trichomes is always very low, so it doesn’t usually receive the attention given to other, more plentiful compounds of the plant with a much more noticeable presence, such as THC, CBD or CBN.

CBL or cannabicyclic molecule (Photo: Wiki Commons)

CBL or cannabicyclic molecule (Photo: Wiki Commons)

One of the main characteristics of CBL is the absence of psychoactivity in its effect, which is why it is not listed in the Convention of Psychotropic Substances. In fact, CBL shares its formula with many of the other phytocannabinoids produced by cannabis, even with psychoactive compounds, although it differs slightly – as in the other cases – in its structure, in the ordering of the atoms that make up the molecule, meaning that its effects vary enormously. For example, THC or tetrahydrocannabinol (the main psychoactive cannabinoid of cannabis) and CBL differ mainly in the absence of double …

How to get your cannabis grow tent ready to grow:

In this post we’ll tell you how to properly assemble and install all the necessary devices in your grow tent to start your indoor grow. This step-by-step guide basically explains how to install your air extraction fan and activated carbon filter, how to mount your grow light and how to program your timers. Let’s get started then!

Indoor grow tent

Indoor grow tent

First thing to do is assembling the grow tent by following the manufacturer instructions. Then, connect the activated carbon filter to the extractor fan with some duct tape. Once it is properly sealed (you can also use metal duct clips) you can make the necessary electrical connections (two wires).




Next, you must hang up the carbon filter and the extractor fan with the strips included in your grow box (see pics below). Then, connect the air duct to the air fan and pass it through one of the holes designed for such use. The ideal would be to remove the air inside the grow tent to another room or directly to the outside. Also, keep in mind that it’s always better to place the carbon filter on top of the interior space, since hot air rises.

If necessary, you can leave one of the bottom holes open as …

7 high yielding cannabis strains

, , No Comment

Among the myriad of marijuana strains available on the market nowadays, some of them stand out for certain traits which have been fixed during the breeding process and that will determine the main characteristics of each genetics. The most desirable and sought-after traits are normally fast flowering, certain size or flavour or very high yield.

In this article we’ll focus on those cannabis varieties that stand out for their abundant production of buds, without a doubt one of the most desirable traits for growers. Indeed, you may know people looking for different flavours, or certain growth pattern, or a specified bloom period…but all of them love their plants to produce abundant harvests!

Yields of some strains are considerably higher than others

Highly productive cannabis strains

Among our category of productive cannabis strains we can find genetics sharing some the aforementioned traits, but all of them offer excellent production of flowers, which is normally above 500g/m2 (if growing conditions are optimal). Let’s take a look now at some of the most interesting ones, especially if traits like easy cultivation, quality and a relatively short bloom period are also to be considered.

Cannabis trends in the USA (2017)

Marijuana trends in American dispensaries

Without a doubt, the USA have been a point of reference in the development of new and amazing cannabis strains ever since the decade of the 70’s, which normally take only a few years to become popular in Europe. Thus, and if we want to know which strains will be increasingly demanded in the near future in the Old Continent, we must definitely take a look at the current scene in the US.

Moreover, the legalisation in some States has led to a much more bearable situation for breeders and growers, who can now focus on developing new varieties without the worry of being caught by the Authorities. In this way, massive selections and large-scale breeding projects are being done today in the USA, which will doubtless led to a new generation of top grade marihuana genetics.

The first hybrids ever developed in the USA and exported into Europe were normally kept in Holland, where they were bred and crossed to develop both seed versions of the American clones and new hybrids. European growers should wait for a few years in order to grow these new and exciting genetics from the USA, which were actually being reproduced in Europe.

But today things have changed a lot. Communication between …

Origins of cannabis cultivation

Where did cannabis originate?

Mankind and cannabis have maintained a close relationship throughout the History. Although scientific and archaeological evidence allows us to estimate the date and place where it originated, it is difficult to establish its exact place – and time – of origin.

The Yangtze River, one of the possible areas of origin of cannabis


Different researchers have proposed three possible places of origin of the cannabis plant:

  • China: Along the Yellow and the Yangtze Rivers (Li 1974b). The first remains of the use of hemp have been found in China in the form of a fiber, as well as the oldest paper sample of the history, which also contains cannabis fibers. Some of the earliest records of the use of hemp also come from this country. It has been found that ancient Chinese treatises of medicine already distinguished between ‘ma fen’ (psychoactive seed) and ‘ma tze’ (non-psychoactive seed).
  • Central Asia: From the Caucasus to the Altai Mountains (De Candolle 1882). The neighboring region to the Takla Makan desert has been proposed as the birthplace of this plant, since from there it could have easily spread into three directions: East towards China, South to India and West towards Europe. Vavilov (1931) suggests that cannabis might have its origin in the northern part of Afghanistan and the

Growing cannabis in harsh climate conditions

, , No Comment

Although cannabis performs well in many latitudes, a rigorous selection of the genetics that we’re going to grow is sometimes necessary in some places in order to harvest our plants successfully, especially outdoors. In this article we will focus on two classic, adverse climate conditions: cold and humid areas – like Northern Europe – and hot and dry climates, where the different cannabis seeds won’t develop in the same way.

Cannabis strains for humid and cold climate

While high humidity promotes a lush and healthy growth, things are different during the flowering stage, when flowers can be infected by mildew and other pathogenic agents due to the effect of cold temperatures and rains. However, it isn’t impossible to grow in these regions, and many growers from places like the Netherlands, UK, Germany, Canada or even Alaska successfully harvest their outdoor cannabis crops every year, mainly thanks to an accurate selection of the genetics grown – always looking for the most resistant strains – and of course the use of greenhouses, greenhouse heaters, etc.

Before presenting you a brief list of this type of genetics, especially suited for outdoor growing in these areas for being particularly resistant to moulds, we are going to explain a few desirable traits that might ensure the best possible results.
