Legal Warning – France
In France, the cultivation of cannabis containing THC is prohibited, including at home and for personal use. This page is provided purely for informational and educational purposes (plant biology and growth phases). It does not constitute an incitement or a guide for illegal cultivation. Only the cultivation of industrial hemp (less than 0.3% THC) is authorized, under strictly regulated conditions and reserved for registered farmers.
Key takeaways
- In France, cannabis (THC) cultivation is prohibited, including for personal use at home — this page is purely informative.
- The botanical cycle of the plant includes four phases: germination, vegetative growth, flowering, and harvest.
- Light, substrate, nutrients, and climate largely determine the plant's physiology.
- Cannabuben offers lab-tested CBD products (less than 0.3% THC, legal in France); this content is botanical information.

Growth Phases
The botany of the cannabis plant
Understanding the cannabis plant requires knowing its fundamental needs. Like any plant, it relies on five essential factors: light, water, nutrients, air, and the right substrate. These general botanical principles are the same for most cultivated plants.
The plant's life cycle is divided into four main phases: germination, vegetative phase, flowering, and harvest with drying. Each phase has specific requirements for light, nutrients, and environment. This content is provided for botanical information purposes and does not encourage any prohibited practices.
Indoor vs Outdoor
From a botanical perspective, both environments have advantages and limitations. This comparison is presented for informational and theoretical purposes only, and in France, applies only to legally authorized cultivation (regulated industrial hemp).
Indoor Cultivation
Controlled EnvironmentIndoors, all environmental factors can theoretically be controlled. With a grow room, LED lighting, and an aeration system, conditions remain stable throughout the year, regardless of the weather. From a botanical standpoint, this allows for consistent quality and multiple cycles per year.
Outdoor Cultivation
Natural GrowthOutdoors, the plant benefits from natural sunlight. It can reach a larger size and higher yield but remains dependent on weather, season, and local climate. In Europe, the natural season generally extends from May to October. This description is botanical and theoretical.
The 4 growth phases
From seed to harvest, each cannabis plant goes through four major botanical phases. Each phase involves different requirements for light, nutrients, and environment.
Germination
2–7 daysGermination is the first stage of the plant's life cycle. Botanically, the seed is kept in a moist environment until a white radicle appears. A temperature of 22 to 25 °C and regular humidity favor this process. The seedling stage begins as soon as the first cotyledons appear. General botanical information.
Vegetative Phase
3–8 weeksDuring the vegetative phase, the plant develops its stem, leaves, and roots. Indoors, a cycle of 18 hours of light and 6 hours of darkness (18/6) is commonly used in horticulture. The plant consumes a lot of nitrogen (N) and moderate amounts of phosphorus (P) and potassium (K). Theoretical descriptions for informational purposes.
Flowering
6–12 weeksIn photoperiodic varieties, flowering is induced by switching to a 12/12 cycle. The plant then forms flowers gradually covered with trichomes. Needs shift towards more phosphorus and potassium. The temperature is slightly lowered (20–26 °C) and humidity reduced (40–50%) to limit mold. General botanical information.
Harvest & Drying
2–4 weeksBotanically, maturity is recognized by the color of the trichomes: milky white indicates peak concentration. After cutting, plants are dried upside down in a dark room at 18–22 °C and 55–65% humidity for 7 to 14 days. Curing in airtight jars for 2 to 4 weeks enhances aroma. Theoretical information.

Frequently asked questions
about the plant.
The essentials to know about cannabis botany – from the legal framework in France to general plant biology concepts, presented purely for informational purposes.
No. In France, the cultivation of cannabis containing THC is prohibited, including for personal use at home. Only the cultivation of industrial hemp with very low THC content (less than 0.3%) is allowed, and only by registered farmers using varieties listed in the official catalog, under strictly regulated conditions. This page is provided purely for informational and botanical purposes and does not encourage any illegal practices.
