So ive just started my plants and two of them havr sprouted but im noticing either small fruit flys or gnats flying in my grow box. I am worried this is going to be a problem if I dont solve it soon. The box is pretty sealed up but the intakes dont have screens :/ that may be my problem
Your problem is you are giving them too much water. Let the soil dry out before you water EVERY time.
there's a lot you can do. my friend watered, and then covered the top of his medium with sand. you can also use sticky traps/ soapy water/ lady bugs/neem oil/etc.
Yea, sand is cheap, the coarser the better; it's been said that the sand cuts their wings off? Can anyone confirm from their own experience (the cutting of the wings, that is)? I never had that problem but once, using Coco ... my problem wasn't severe so I would keep a small vac available and would suck them up.
The sand is like little razor blades to them. Their bodies are soft and when they try to dig in/out, the sand slices them to shreds. So, in a way, I guess you could say it takes their wings off, but in reality, it is WAY worse than just that.
