Gnats are really a nuisance specially when the atmosphere is humid and moderate. Tents have this problem because they are not exposed to sunlight, and gnats keep coming as long as they find a nice controlled atmosphere.
Protecting the moist soil with any kind of pest control may help reduce their population. Are they fungus gnats?
Yeah there fungus gnats, most likely came from some compost I added a little while ago. The humid level is between 40-50%. I’ll be dropping to 45% soon, then to 40% the last 2 weeks:)
