Types of grow lights for indoor cannabis cultivation

, , No Comment

How do we light our cannabis growing space?

When we decide to set up an indoor cannabis grow for personal use at home, there are many factors to take into account if we want to get the best results, but one of the most important to consider is the type of light and its power consumption.

When deciding on the type of light to use, we must keep in mind that each technology has its different advantages and disadvantages with respect to growing cannabis. Certain types of bulbs will offer the best yield (lumen per watt) but at the same time they are a considerable heat source that can cause problems to many growers, especially those that live in particularly warm climates or are only able to grow cannabis in small spaces.

On the contrary, other types of illumination emit almost no heat at all, although often the high price of this kind of lighting, combined with its lower effectiveness when compared to other systems, combine to make them less popular. They are, however, indispensable to the many indoor growers that can only cultivate cannabis successfully thanks to the low heat emission of these lights.

How to make THCA Crystals & Solventless Sauce

, , No Comment

Why isolate cannabinoids?

In recent times we’ve seen a great increase in the amount of isolated cannabinoids coming onto the market, with CBD crystals and pure THC distillate becoming a more frequent sight on the menus of dispensaries. Their popularity is mostly due to the ease of calculating dosage amounts. While the vast majority of resin extracts have an unknown cannabinoid content, when we isolate a cannabinoid, users can be confident that they have a product with a purity approaching 100%, which makes it very simple to adjust dosage to a specific amount of milligrams. This is particularly important when preparing edibles, tinctures or other products for oral consumption, where knowing the cannabinoid content is vital to avoid any ill effects caused by ingesting too much THC.

Pure Solventless THCA Crystals

THCA Crystals isolated using this method

For the most part, these isolated cannabinoid products are the result of complex processes that employ expensive equipment, volatile chemicals and in-depth, specialist knowledge that are far out of the reach of the average home grower, extraction enthusiast or fan of cannabis concentrates.

Cannabis risotto with saffron

, , No Comment

Risotto is a traditional Italian dish made with medium graine rice, which should be rich in starch. This recipe comes from the Verona area, since top quality rice is widely found there, as well as the other main ingredient of rissoto, cheese. In Italy, rissoto is defined as “minestra asciuta“, which means dry soup and indicates that the resulting preparation must be neither dry nor too liquid, but with a creaminess that allows to use a fork.

Risotto, along with pasta and pizza, are probably the three flagship dishes of Italian cuisine. Despite the main ingredient of today’s recipe is rice, we are going to use it as a vehicle to transport the rest of flavours that we want to incorporate to the dish. You can use a wide range of ingredients to complement your rice, the only thing to keep in mind is to achieve a correct balance between the different flavours. Thus, you can use vegetables, seafood, poultry meat, bush meat, guts, spices, wines, etc.

5 Cannabis varieties with discreet aromas

, , No Comment

Among its many cherished characteristics, cannabis is highly appreciated for its aromas, but sometimes plants can generate a smell so powerful that it can attract the attention of neighbours and this issue can become a serious problem for those growing weed outdoors, where maximum discretion is essential and in which the use of carbon filters or other anti-odour systems is impossible.

In these cases choosing a cannabis variety that gives off discreet aromas is a good idea if we want to limit the smell generated by our garden, especially for outdoor crops on terraces and balconies. For this reason, you should avoid any genetics that stand out for their powerful and telltale aromas typical of cannabis, these include the varieties of the Diesel or Skunk families, Cheese or the Sour Diesel among many others… we are talking about varieties with a very high terpene content, which are distinguished by their characteristic, persistent and highly volatile aromas.

In this article we look at a selection of the varieties most recognised for their subtle and discreet scents, to help you avoid security headaches and uninvited guests at your grow spot.

Cannabis in Afghanistan

, , No Comment

Afghanistan is a landlocked country in central Asia, wedged between the western foothills of the Hindu Kush and the deserts of Iran, is a country with one of the greatest traditions of cannabis cultivation and, more specifically, of hashish production. Since it is believed that cannabis originated thousands of years ago on the slopes of the Himalayas (home of the largest mountains in the world), today it seems obvious that this was one of the first places where this plant was cultivated in a controlled manner, although even now there is still some confusion as to what kind of varieties have been traditionally grown in this area, as well as the “emergence” of the Afghan genotype, or in other words, what we now refer to as Afghan varieties.

What is clear is that Afghanistan is one of the cradles of cannabis and especially of hashish, with a tradition that today represents what would probably be the world’s oldest in terms of the development of hash. In addition, and according to the UNODC, in recent years Afghanistan has become the world’s largest producer of this resin concentrate, surpassing Morocco and seeing the cultivation of cannabis gradually displace that of another traditional crop in the Golden Triangle area, that of opium.

Puffco Peak Smart Rig

, , No Comment

The Peak Smart Rig

The world of cannabinoid extractions is in a golden age, these days more and more users are switching from the combustion of flowers to the vaporisation of resin concentrates. The main reason for this change is to avoid inhaling smoke and its harmful derivatives, and instead to vaporise, obtaining a medicinal effect free of impurities and contaminants.

E-nail Puffco The Peak

Puffco The Peak Smart Rig

These precious resin concentrates also demand high quality products with which to consume them, for example the Puffco Peak, which allows us maximum enjoyment of the terpenes in the extract, capturing all the flavours of the plant.

The Peak is the next step in the evolution of e-nails, which until now have always been bulky devices that require a mains socket or transformer to provide the power needed to reach high vaporisation temperatures and fully enjoy the most pure and tasty concentrates.

With The Peak Puffco has taken the essence of the old style e-nails and recreated it in a stylish, elegant option that’s easy to use, small in size and forgoes the need to buy a bubbler or pipe in addition to the e-nail itself.

Causes of death in plants during the growth period

Causes of death in cannabis plants during the growth period

The vegetative growth of cannabis plants can be one of the longest periods of cultivation when growing outdoors – or indoors – where in, for example the countries of southern Europe they enjoy a lengthy spring and summer. During the course of this growth phase, problems can arise that may lead to the death of the plant even before the flowering stage begins.

Let’s see what are the most frequent causes of death during the plants’ growth period and what we can do to avoid a premature, unhappy ending.

Cannabis plants in growth period

Cannabis plants in vegetative growth

Overwatering cannabis plants

The most common cause, especially among beginner growers, is undoubtedly overwatering. The excess of irrigation particularly affects young plants in their first weeks of life (although it can also occur with larger plants).

The main reason is watering too much, too frequently. Small plants have a very limited resistance, partly because of their size. A plant with two cotyledons and three small roots can not cope with large amounts of water, simply because they can not process it, not having sufficient absorption capacity in the root zone.

With this growth in popularity, the number of purpose-built presses on the market has increased hugely over the last year, with a wide range of different sizes, styles and prices available to the budding extractor, depending on his or her requirements.

In posts over the last few years we’ve shown you how to make rosin from flowers and then from hash using a simple electric hair straightener, a great and inexpensive way to get started in this world of solventless cannabis extractions. But now it’s time to look at how to extract on a larger scale, using a hydraulic press and heated aluminium plates.

The principals of the extraction process are the same, as are the variables to control: temperature, pressure and time. However, things are a bit easier in the case of a professional press, we’ve got more pressure at our disposal, the temperature …

Thai green chicken curry with cannabis

What is curry?

Curry is the western name for a group of different dishes prepared with a mixture of spices commonly used in Asian cuisine. This type of recipes spread across the globe mainly thanks to the diffusion of Asian cuisine during the times of British colonies in Asia, around the XVIII century.

Thai green chicken curry with cannabis

Thai green chicken curry with cannabis

Types of curry

In short, curry is a paste prepared with different Asian spices – always depending on the location – which may include: chili, basil, celery, saffron, cinnamon, cardamom, coriander, lemongrass, turmeric, ginger, mustard, pepper or nutmeg, among many others. Each country and area has its own recipe, so it is not strange to see plenty of variations of this recipe. For example, curry in India usually contains cardamom, nutmeg, peanut, cumin, ginger and coriander and mustard seeds, thus producing a perfectly balanced blend which results in an extremely complex taste.

On the other hand, Thai curry is normaly fresher, with lime, lemongrass, fresh coriander, fresh basil, fresh ginger and galanga. In this way, the flavour is fresher and citrus especially when compared to the traditional recipes from India. We are also going to use some cannabis infused milk, so you’ll have to have at hand some buds of your favourite cannabis strain!

LST – Low Stress Training for cannabis plants

, , No Comment

Plant training – a low-stress alternative to pruning

Cannabis is a robust, vigorous and fast-growing plant which responds very well to crop optimisation techniques such as: pruning; propagation via cuttings; hydroponic cultivation and more. In a previous article we looked at the so-called “destructive” techniques like pruning, super-cropping, etc, and in this article we’re going to talk about a very useful technique both for indoor and outdoor growers: Training or tying down, often referred to by cannabis growers as LST (low stress training). This technique originated in the agricultural sector, where for generations vineyards and orchards have been cultivated using a variety of training techniques, to facilitate harvesting and improve the productivity of the crop.

Plant training is a traditional technique in vineyards and orchards

Why train cannabis plants?

The most common use of training is to limit the height of our cannabis plants, whether it’s in order to make sure they stay at a discreet height and out of sight below a wall or fence when we’re growing outdoors or to keep the tops of the plants at the proper distance from our indoor grow lamps, we can bend and them to manipulate their structure, without needing to top them or cut the growing tip.

Ozone, the cannabis cultivator’s friend

Ozone (O3) is a substance that is a colourless gas at ambient temperature and pressure, giving off an acrid smell; Thanks to its high oxidising power, this gas has a great ability to disinfect and eliminate odours. Nowadays, ozone has many applications in areas as diverse as industry, agriculture, or domestic sanitation, being of particular interest for the indoor cannabis cultivation.

Atmospheric ozone is best known for forming the infamous ozone layer; This is a type of pure ozone that is found in different concentrations between 10 and 40 km above sea level, its two main functions being to act as a filter for ultraviolet rays emitted by the sun and as an air purifier.

Ozone has the honor of being the first allotrope of a chemical element identified by science. In 1785, a Dutch chemist called Martinus van Marum noticed a strange smell while carrying out experiments with electric shocks and water and believed that the smell came from the electrical reactions; in fact, that smell came from the ozone he had created without realising it.

Since then, both the techniques to generate ozone and …

Responsible use of pesticides in cannabis cultivation

, , No Comment

At this point in the season, when outdoor plants begin flowering and indoor grows are suffering the highest temperatures of the year, it’s common for pests to make their first appearance in our garden, which can be particularly difficult to combat precisely because of the high temperatures, that on most occasions will favour their development and propagation. Our plants are therefore more sensitive than ever to insect pests and, later on and once they have developed buds, to the dreaded fungi.

Because of this, it’s the season of the year where the most insecticides (early summer) and fungicides (late summer) are used, because no grower wants to watch their efforts and dedication be ruined by a pest or disease. However… are we making the best use of pesticides? How can we limit its impact on our health and the environment? This article was born from my own experience during the years that I spent cultivating cannabis outdoors in my garden, when I saw the fauna in it gradually diminish and, fortunately, how I’ve seen its resurgence in recent years thanks to a more responsible use of phytosanitary products.

How to increase sugars in cannabis plants

Carbohydrates or sugars in the cultivation of cannabis

What are carbohydrates?

Carbohydrates are a group of compounds that include sugars, starches and cellulose among many other substances. These are formed by carbon, hydrogen and oxygen.

They are vitally important compounds for both plant and animal life. They perform vital functions so that plants can develop healthily and problem-free in all stages of their life and also serve as a source of food for the animals that feed on plants.

Bubble Kush, 44 days, fed with aminoacids

Bubble Kush, 44 days, fed with aminoacids

There are two major types of carbohydrates, the so-called structural and the non-structural. The structural carbohydrates are known to make up part of the cellulose that forms plants cell walls, giving rigidity to the stem, branches and roots, etc., all parts of the plant that keep it standing upright, and without them plants would fall over.

Non-structural carbohydrates are stored in many parts of the plant, for example the stem, roots, rhizomes, stolons, as well as the aerial part of the plants where they play a vital role as the source of energy that the plant relies upon in order to carry out its metabolic functions. They are the fuel the plant needs to keep growing.

But exactly what functions do they perform in plants, and in particular, how do they …

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.

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.

Presenting BSF Seeds at Alchimia

, , No Comment

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

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

Cannabis in Jamaica

, , No Comment

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.

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 …

Introducing Cli-Mate Controllers

, , No Comment

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 air conditioning of a grow space must be optimised to create the ideal environment for the plants development.

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 …

7 cannabis strains with uplifting effect

, , No Comment

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!

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%.

Pruning Cannabis Plants

, , No Comment

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.

This plant was pruned multiple times

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 …

Cannabigerol CBG: The main precursor to all cannabinoids

, , No Comment

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.

Origins of Brothers Grimm Seeds and interview with MrSoul

, , No Comment

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 …

Cannabis and endometriosis

, , No Comment

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.

Endometriosis sufferers can often find relief with cannabis

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 …
