CBD cannabis is attracting more and more growers. In Switzerland, as elsewhere, its legal cultivation is attracting those who want to produce quality hemp, rich in cannabidiol but low in THC. In this article, we explain how to grow CBD cannabis step by step, from choosing the seeds to harvesting.
🌱 Choosing the right CBD cannabis seeds
Above all, you need to select a variety suited to your needs and local legislation.
Seeds from industrial hemp or CBD-certified varieties are the safest. In Switzerland, only plants containing less than 1% THC are legal.
💡 Tip: prefer feminized seeds. They produce exclusively CBD-rich flowers, with no risk of accidental pollination.
☀️ Find the ideal location
CBD cannabis can be grown indoors or outdoors.
- Indoors, you control light, temperature and humidity.
- Outdoors, plants benefit from natural sunlight, but are subject to climatic variations.
For good yields, the sun is your best ally. Choose a well-exposed spot, sheltered from wind and glare.
💧 Watering and nutrients
Water is essential, but too much can kill the plant. Water moderately, when the soil surface is 2 cm dry.
Nutrients also play a key role: CBD cannabis thrives in soils rich in nitrogen, phosphorus and potassium.
Natural fertilizers such as compost or guano give a purer taste.
💡 Lighting and photoperiod
If you're growing indoors, use horticultural LED lights to mimic sunlight.
During the growth phase, the plant needs 18 hours of light a day.
During flowering, switch to 12 hours of light and 12 hours of darkness. This transition stimulates the production of CBD-rich flowers.
🍃 Harvesting and drying CBD cannabis
When the trichomes (small crystals on the flowers) turn milky, it's time to harvest.
Cut the branches and hang them upside down in a dark, well-ventilated place for 10 to 15 days.
Then store the flowers in airtight jars for gradual ripening. This step improves the taste and quality of the CBD.
⚖️ Legality and best practices
In Switzerland, the cultivation of CBD cannabis is legal as long as the THC content remains below 1%.
It is therefore important to have your flowers analyzed by an accredited laboratory before they go on sale.
Respecting the law guarantees the credibility and sustainability of your cultivation.
🌿 Summary
Growing CBD cannabis requires patience, precision and respect for the rules.
With the right soil, lighting and harvesting, you can produce high-quality CBD worthy of the best Swiss producers.
