Thanks for your repplies.....I stayed with the predator mites and I'm very happy I did. I simply waited a week too long to reapply, they are around 7ft. now. I'll post pics before harvest. I found out commercial greenhouses have successfully been using them for years......Phytoseiulus Persimilis is the critter I ended up with. Their temp. range is 55 to 105...and humidity 60 to 85%, they do have other species with different temp. and humidity ranges. I can now say I'm 100% organic . They do work, if you follow instructions, I'll NEVER go back to chemicals, sprays, or hand washing again, www.hydro-gardens is where I buy mine. As a matter of fact they work so well I'm considering starting a small in sectary and rearing them myself.......:hippy:
