Alright Nerds, everytime I here this gnats talk I always wonder why I never get gnats any more....I grow in 100% Roots organics soil, this is all I use and I've never gotten thrips...at least not in roots, and early on a had a few gnats and used powdered gnatrol per directions and they slowly dissapeared...what I an getting at guys and gals is that from what i've seen....most gnat problems can be attributed to overwatering or keeping the soil too wet for to long...what about potatoes or bannana's or what not. What happens to them when they get gnats were they in thee soil, I think not, but they seem to appear out of no where. What I'm trying to say is if you keep your soil a little dryer, gnats seem to never appear IDK just my observation. Peace
