Uhm..gnats in the grow tent


Gnats have invaded our grow tent. Our grow tent is INside our house, in a storage like room made out of an old garage. *weirdness abounds~ No gnats (that we can see) in the actual room. Just in the tent.
Ideas on how to get rid of them?

Yellow sticky traps, a one to two inch later of sugar and across the top of the soil, let soil dry out completely between waterings…


Sugar? Not heard of using sugar did you mean sand?

I never knew such a thing (fungus gnats) existed til now.


i just bought gnat nix to top dress my pots just in case. 4 of six plants have them, but this is my first grow and i need to keep a way to get moisture meter into soil so i’m not doing it to the other two.
