That's what I'm thinking, and if I didn't live so close to an elementary school I wouldn't be so concerned about it but I don't want to be that neighbor stinking up the place when School is in session. It would be nice to save $ on lights, dehumidifier, and ac for a few months in the summer when the kids aren't there though.Maybe you could build a shed greenhouse that's locked with hps for the winter @Hog MaGundy
