I’m indoors in my bedroom and they aren’t that bad! And I can’t throw out my grow off plants so predator mites and bti will do the trick! I would get nematodes too but not looking to spend $120 on these damn gnats! And soil stays saturated for a hot minute in an earthbox! I put 2 gallons in each reservoir right after transplant and just had first reservoir go empty yesterday! I added yucca this time to make sure the soil at bottom of the boxes are not hydrophobic from going few weeks between grows!
