Pity you didn't think highly of it. Looks like you got a good harvest. Gnats musta came from your supersoil.. when you use all mix & SS, you can check with the maker how to treat. Most will say oven treatment is best. But, it leaves a rotten shit smell in house all day. I use boiling water, and I put tin foil over the top and give it a good shake and move about. Kills all larva, no gnat problems since I've started doing it. It's a pain. Only thing I have issues with a moths.
