Heres the problem.Not sure where you are though.If they found any weed in the house or to be even worse a scale or a box of baggies they will have enough to get a judge to agree you grew the bud if scales and bags found that also is enough to constitue intention to sell or distribute.Im hoping your lawyer is a good skilled drug defense lawyer which it doesnt sound like it more of a genral defense lawyer.Now if they found the stuff and absolutly no bud in the house youd be golden its the fact bud was in the house and was found with grow room equipt that has you in a bind.Your buddies or whoever got the possision charges would have to agree to to take the possesion charge which in most states 42 grams is a felony possesion and lucky if they didnt trump it up as intent to distribute.I hope it goes well but get a second lawyers opinion on this who has dealt with these specific drug cases in your area and if they got a warrant based on aCI (confidential informant) just hope they didnt buy any weed from the house.
