Agree with Papa_T, it should be legal to grow on a global base. Here in the Netherlands it's not allowed, if caught you can get
a fine and they take it away. If you only have 3/4 plants. If you have more they will shut your house for about 3 months....
And if rented they will kick you out and you get blacklisted for a couple of years.
Nitrogen toxicated weed for 8,5/14 euro's per gram. So i have three plants on rdwc....
