    More advice for people making seeds: Those fungus gnats really do kill seedlings. If you use some soil and he plant doesn't make it, and you've ever seen a little gnat flying around on it, you must DRY it out before you use it again, or you risk the next seedling falling over in a day.

    They're not so hard on big plants I guess, but if they've been living in that initially hot soil, which grows fungus for a while, there's a huge hungry population by the time you reuse the soil for a new seedling. With no fungus to eat, they'll kill a seedling overnight.

    I'm try to breed very short plants, so I end up with failed experiments all the time. Northern Lights is particularly perplexing. Low Ryder is nearly trouble free.

    Sterilize your soil.

    I was reluctant to do that because everyone talks about the "beneficial bacteria", but I guess I'd rather have sterile soil than the gnats.

    I also discovered the neem oil spray is not good for seedlings, even if you spray it on the dirt only. Makes distorted leaves.

    A layer of sand on top of the soil can help with gnats, as do mosquito dunks (idk how mosquito dunk affect the buds, if at all, though).

    I'm considering the sand, however my interest is in making a grow kit. I'm afraid, stuff having to go on top of the soil is too complicated for most users. I'll be lucky if I can get them to put the baggies of mosquito dunk powder on top instead of mixing it in.

    Fortunately, my battle with gnats won't happen to someone who buys a grow kit, just to grow one plant. It seems to be a problem that builds up over several grows.

    I read in one place, even drying out all the soil won't remove them. They find a sink somewhere that has some crud stuck in a corner that doesn't get flushed. That's enough to keep them coming.
