I'm currently growing outisde in a home-built small greenhouse, and i'm always seeing helicopters flying around my house, and im getting sketched out, are there any tips on avoiding police helicopters so i don't get caught?
do you mean for real greenhouse? or are you talking a shed with artificial lights in there?
if 1, i would think you had better throw some real flowers and fruits in there...get you a carbon filter.
2? depends on how many lights in there. if you're not running over 3k i wouldnt worry about it. well, im lying cuz i would still polyshield that bitch up!
but two 1500 watt heaters in a work shed could resemble 3k lights so its all up to you bro.....
if it is a shed using artificial lighting i would line the shed with polyshield or something of the like. overlap it when installing/stapling up
