We provide relaxed education about cannabis, out of the criminal milieu and fears, as hemp has many positive health effects. Each adult is allowed to grow a maximum of three flowering plants. However, we are only allowed to store 50 g of dried flowers at home. Once the flower has been processed (into oil, butter, alcohol or cookies), there is no limit. We can grow our own hemp in pots, on our own responsibility. Master gardener Klaus Umbach gives tips from his practical experience of growing cannabis. Important is the pot size, at least 20 liters, a nutrient-rich substrate (e.g. depot fertilization with 50 g sheep’s wool pellets or raw sheep’s wool), even water supply. Hemp is completely uncomplicated to grow, does not get pests, but needs a sunny location, lots of nutrients and water if you want to harvest a lot. The Bioland nursery sells strong young plants of the best, consistent organic quality. You know what quality you are getting to test out for yourself.
