I'm not sure if sand would help or not... the DE was my prime goal. Getting a nice dusting across the coco. But I figured the perlite would help keep that top inch dry so them little bastards don't have anywhere to bang anymore.Yo am i right in thinking sand can help with fungus gnats when spread over the top like that?
Seems to have dissipated the herd already.
I guess sand should have a similar effect but removing their little hump shack.
