Hello, I’d like to summarize current legal situation when growing marijuana in different countries - I hope you can share your own country’s policy so we can compare different kind of government approaches… Let me start:
Czech republic - "5 plants rule"
Theoretically there is “tolerated” limit of 5 plants. If you grow up to 5 plants and get caught it is considered minor offense (not criminal act). You can’t go to jail for minor offense - there is no court or hearing, only civil servant can give you fine.
Growing hemp containing the active ingredient above THC 0.3% is considered misdemeanor according to § 30 paragraph. 1 point. k) Act. no. 200/1990 Coll. misdemeanors, while for small amounts is considered to range up to five plants. Six or more grown plants with a THC content exceeding 0.3% is considered a criminal offense under § 285 of the Penal Code no. 40/2009 Coll. And that goes for any cultivation including medicinal purposes, even if producer is holder of the license granted by the Ministry of Health.

In practice: Police doesn’t actively seek “small fishes”… But if there is neighbor allegation they must act. When caught it depends if prosecutor finds evidence that you have sold substantial amount. If not it is just illegal “drug production” which when combined with proper defense (medical purposes, ointments) in 99% of cases leads to parole.
I don’t know / heard of anyone who would have been sentenced to prison for pure growing… When combined with selling/distribution its whole another story (3 - 5 years in jail is not uncommon).
