One other thing. This is in a tent which I am using CO2 in. Weird thing once I started using it, they all seemed to be hovering around in the top of the tent trying to find a way out. Is it possible the high amounts of CO2 were driving them out from the base of the plants?
One grower reports 10,000 ppms for 24 hours i think it was will destroy the little beggers! I can believe that one, just make sure you wear scuba diving gear! lol!
