You never had gnats because it's your first grow. Why tell someone that they shouldn't worry about gnats because "you never had them" that is some pure gospel, preach it! Seriously, that is your help, you said "I've never had gnats". BTW, gnats eat roots and they ARE a problem if not taken care of. The solution is so simple. Are you going to accuse me of selling Mosquito Bits now, because I did recommend it after all. You can also buy it on Amazon. I must be a fucking spy or something.Although I know fungus gnats obviously live outside, I don't think I've ever seen one before LOL!
Fungus gnats aren't normally something I worry about, at least in no-till. Yeah they were a moderate issue in cycle #1 and smaller in #2, after that for me they were not to be seen. Even yellow cards will not get a single one now in cycle #7. Don't worry much about them if you're establishing a no-till.,
