Putting a layer of sand on top of your soil will stop the fungus gnats from bieng able to burrow and breed under the soil. You just have to water them gently afterwards to keep the sand in place and not wash it down into the soil
Wobster Reviewed by Wobster on . Can you help Identify Alright. Well i can't tell if this is a problem or not, but i'm getting brown spots on some of the leaves that are starting to yellow. I'm in week 5 and i'm unsure if the leaves are already starting to drain themselves, a ph problem or an infestation. There are gnats that circle around the lights but i put up fly paper, kills alot of them. Anybody have an idea? Rating: 5
