its not WRONG, but think of your self 20+ years from now if you find a plant in your kids room. or even worse cops find it and you go to jail because your kid is a minor, and grew something you had no idea was in your house. just think about things in the long run before you do them.
do you think your parents are stupid enough not to notice the electric bill going up for 3 mo, or they wont smell the dank when your flowering, or they wont come in your room to put some laundry away and see light pouring out of the closet or hear the fan running.
what i mean to say is we make our own decisions
edit: you dont have to say how old you are, they already suspect your -18 because your debating growing in your parents house. i see someone get banned daily for being -18
