I was wondering if any one has a good way of controling thrips and
fungas gnats in S/H, I have tryed neem, systems, BTH and soaking, I
still have the freeking critters (the gnats I can stand, but I HATE
thrips)

I have no idea whether this method will have unintended consequences, but an
even layer of fine white sand about 1/4" thick will quickly smother your
annoying gnats.

How can you put sand on top of S/H? It will work down into the
PrimeAgra or expanded clay.
