Definitive fungus gnat solution for hydro

seting aside all the negative between us if there is? and I say theres not on my end. all I asked for was some pics of it in use! never dissed your idea
and as stated a alteretive to liquid chem like azamaxe and other im interested in.

Yeah just a very bad day and some misinterpretation on my end. I'll post some pics although it doesn't show much. Just looks like flour shaken on the surface. The stuff is the bomb. I'm haven't looked into if it is the crystalline stuff that is indeed so hazardous but I have been spending allot of time in the field at work and haven't had the opportunity

I know you all are speaking of hydro, but you need to be careful oo using too much with soil. Too thick of a layer in soil can create clay like soil with minimal aeration. It will also leech heavily out the bottom. IMO very limited success in soil.

I was told that if you are top watering in soil to use a small PVC pipe to water so you don't get it all wet. You don't need a solid layer of it, just give it a solid dusting
