If you go to your local nursery I bet you could find a little pot of sweet clover there and in that pot will definitely be some pirate bugs, then just put that pot in your grow room and your grow room will be free of all above ground pests in a week. Pirate bugs are pure killers ,you only need 3 or 4 of them in a 100 sf area to keep you garden free of every pest that could harm a cannabis plant. Why, because while they may only kill and eat up to 20 bugs and larvae a day, they will also purposely kill some 50 more each day, and they do that just to kill them.
