you should knock you friend out!! well, just think about knocking them out.. don't smoke none with them.. I've had bad experiences with friends and growing bud which tells me if you wanna keep your friends, don't involve them... my last hydro grow about 2 years ago got totally fucked because the house i grew at became non enterable for 2 weeks. The guy who owned it fucked off without a care in the world. thing is, at the end of every grow he always said "i thought there would have been more than that.." twat! He never did anything to contribute besides helping with the triming at the end which wasn't that difficult as the maximum number of plants were 4.. Whatever mannnnn!
