If you are 18 years old or older and you want to grow cannabis at home, you must have a licence from the federal government.
You can get a licence if you have a medical reason that requires you to use cannabis.
How to grow cannabis?
How do you grow cannabis? There are a few ways. You can grow it indoors, outdoors or in a greenhouse or tent. Outdoors is most popular and generally considered the best way because when growing cannabis outdoors your plants receive more light and nutrients than when growing indoors (but this depends on what type of setup you have). In order to get good results, most growers will use both indoor and outdoor growing techniques as each has their own benefits depending on what kind of setup they have available.
