Marijuana Grower's Handbook

Since the Cannabisgesetz (CanG) came into force on April 1, 2024, Germany has become one of the most significant home-cultivation markets in Europe. The law allows adult residents to acquire up to 25 grams of cannabis, possess up to 50 grams at home, and grow a maximum of three plants per person for personal consumption, with the express obligation to ensure that minors have no access to them. Under the climate of northern Europe, autoflowering varieties are emerging as one of the best alternatives. Let's take a closer look at how to grow them under these conditions.

Energy Efficiency in Cannabis Cultivation

The debate between indoor and outdoor cultivation is not just a matter of quality or yield — it is, increasingly, a question of environmental responsibility. The scientific data is clear: marijuana production under artificial light is one of the most energy-intensive agricultural activities. We break down the numbers, the causes, and the paths toward more efficient cultivation. Although in cannabis cultivation these figures are skewed by the legal status of growing in each country, since in most of them indoor cultivation is not a choice but the indirect consequence of prohibition. Most of the data reflected in this post comes essentially from the USA, as it is currently one of the few countries in the world where intensive marijuana cultivation is legal and therefore one of the few countries from which data can be obtained.

How to make homemade pesticides for marijuana home growing

One of the biggest challenges faced by home marijuana growers is controlling pests and fungi without compromising the quality of the final product or the balance of the growing environment. Conventional chemical pesticides can leave toxic residues on the buds and many of them are not specifically approved for cannabis cultivation, making them a risky choice both for consumer health and crop integrity. In contrast, organic homemade preparations represent a real alternative — effective and, above all, much safer.

Overfertilization and cannabis

In cannabis cultivation, mineral nutrition is one of the factors that most decisively determines the quality and quantity of the harvest. However, one of the most common mistakes among growers of all experience levels is supplying nutrients in excess, under the premise that more fertilizer equals more production. The available scientific evidence demonstrates that this premise is not only wrong, but that it can have profound consequences on the plant's physiology, cannabinoid and terpene production, and even the viability of the crop.

Use of companion plants in cannabis cultivation

Growing cannabis as a monoculture is the norm in most gardens, both indoors and outdoors. However, from an ecological perspective, this model is far from optimal: it progressively depletes the soil, encourages the proliferation of pests and pathogens, and disrupts the biotic balances that nature has taken millions of years to build.

The Super Cropping Technique in Marijuana Cultivation

The Super cropping technique (also called “super crop” within High Stress Training or HST) consists of crushing and bending a branch in a controlled way to partially “interrupt” its internal tissues without actually snapping it. The goal isn’t to cause damage for the sake of it, but to improve the plant’s structure in order to achieve a more even canopy, better light distribution, and branches that are more capable of supporting heavy flowers.

Soil Regeneration and Cannabis

Talking about cannabis and “soil” often stays stuck in recipes (mixes, fertilizers, watering charts). But if the goal is consistent quality, resilience, and less dependence on inputs, the approach changes: soil stops being a simple support and becomes a living system that can be regenerated. This article covers soil health principles and regenerative practices applied to cannabis (and hemp) cultivation, with a technical but accessible perspective.

Growing automatic plants in mother plant cabinets

The autoflowering varieties come from crosses with Cannabis ruderalis and are characterized by flowering according to their age rather than the photoperiod. This means they begin to form flowers between the second and fourth week after germination, regardless of the number of hours of darkness they receive. This pattern makes them especially interesting for mother plant cabinets or small auxiliary cabinets because you can maintain a long and stable light cycle for your conventional mother plants—such as 18 hours of light and 6 hours of darkness—while also growing autoflowers that will complete their cycle in about 10–12 weeks without needing to change the timer. Compared to classic varieties, automatic plants tend to be more compact, faster and less tolerant to stress, but they allow several harvests per year in very small spaces and without complications related to photoperiod changes.

Fungus gnats in cannabis cultivation

The so-called fungus gnats in marijuana cultivation almost always correspond to mosquitoes of the Sciaridae family, known in English as fungus gnats (genus Bradysia and related). They are a typical pest in potted crops and moist substrate systems, including cannabis, especially in indoor spaces and grow rooms with high humidity.

Cannabis and mealybugs

Outdoor cannabis cultivation faces various threats in the form of pests, and one of the most persistent and problematic is the mealybug. These small insects can cause significant damage to your plants, affecting both their health and the quality of the harvest, thus compromising your efforts over the last few weeks. In this article, we offer you a complete guide to understanding what mealybugs are, how to identify them, the damage they cause, and the best strategies to prevent and control their presence in your cannabis crop. Nothing is more annoying than spending months caring for your plants only to end up seeing them covered in these annoying and unsightly insects!

Lollipopping and cannabis

In cannabis cultivation, pruning techniques are essential to manage plant development and optimize the production of high-quality flowers. Cannabis plants, being robust and adaptive, respond well to selective pruning methods that allow growers to adjust their structure and energy distribution according to their needs. Pruning not only improves the quality of the buds but also helps prevent pest problems, increases light penetration, and facilitates air circulation, crucial elements in efficient cultivation. Among the featured pruning techniques is our protagonist today, the Lollipopping method, ideal for maximizing the quality of the top flowers in indoor crops and in tall plants where light, whether natural or artificial, reaches in a limited way. Keep reading and we will tell you all about it!

Caterpillars and cannabis

Growing cannabis outdoors faces several challenges, and among the most problematic pests are, as you probably know, caterpillars. These moth and butterfly larvae actively feed on leaves, stems, and buds, causing structural and aesthetic damage that directly affects the health and productivity of the plant, as well as attracting fungi such as the dreaded botrytis. Exposure to natural environments facilitates the arrival of this pest, which usually increases during the warmer months. In addition to their visual and physical impact, caterpillars can cause secondary diseases in plants due to the wounds they leave, which open the door to infections caused by viruses or fungi. Today we explain how this threat acts on your plants and what you can do to keep it under control.

7 Philosopher Seeds cannabis strains to help you sleep

Traditionally, cannabis has been used for centuries for its various therapeutic effects, and one of the most common reasons for its use is the ability of many varieties to induce a deep feeling of relaxation. Indica-dominant varieties, rich in THC and other cannabinoids such as CBD, have sedative effects that help reduce stress, and anxiety and, above all, help to fall asleep, a problem that affects millions of people around the world today. Terpenes such as myrcene and caryophyllene also play a key role in this relaxation, enhancing the "couch-lock" effect, which facilitates rest. The proper selection of a relaxing strain can be essential for those seeking effective relief from insomnia or daily stress, so today we have proposed to invite you to discover 7 genetics from our catalog that will definitely help you relax your body and mind and prepare your body for a restful sleep.

What is triploid cannabis?

Earlier this year 2022, Dark Heart Industries, one of the leading cannabis genetics companies in California, announced that it had produced the world's first triploid seedless cannabis for commercial growers. Dark Heart's 'PistilGuard' technology purportedly produces triploid cannabis seeds and clones that are essentially unable to produce seeds, even when directly exposed to pollen. This technological innovation means that triploid cannabis can be grown on the same scale as maize or wheat, minimizing the risk of accidental cross-pollination and seed production. “The introduction of this characteristic in cannabis is a real advance that will allow higher yields, a drastic reduction in costs and better aromatic and chemical qualities of the crop. All of this leads to increased profitability,” the company said in a press release. According to the company, the ability to grow THC-rich cannabis from sterile triploid seeds and clones that guarantee the production of seedless plants "is a huge win for growers" as pollen-proof cannabis and the benefits that offers "will help marijuana production move from artisanal cultivation to the large-scale agriculture division."

What are cannabis landraces?

In many countries, it is now easy to find seeds of hundreds of cannabis strains on the market. However, most of these seeds are hybrids, that is, crosses between plants with more or less different genetics, or direct crosses between hybrids, which further increases the genetic mix that these varieties present. But where did the first marijuana hybrids come from? What plants were used for its development? Well, they were the pure varieties or landraces, genetics adapted to a specific environment and that, at the time, were cultivated in other territories for the creation of the first hybrids. Today we will talk about them and we will see their importance to explain the current situation regarding cannabis varieties.

Aphids and cannabis, how to avoid and combat them

Aphids are parasitic insects that feed on a large number of plant species and represent a serious threat to many crops. Their adaptability and high reproduction rate make them a pest to be taken seriously, especially when they are accompanied by other insects such as ants. Today we are going to tell you everything you need to know about these annoying insect pests and explain a trick that works wonders for eradicating them from your plants, because you don't want to spend months looking after your garden only to have these little insects come and devour everything!
