Yes... I been using about 1.5" GnatNix on top of coco, in smartpots for over a year.
I use compressed brick coco that i hydrate with 140°F water to eliminate any freeloaders.
For me, it is just another form of control. It does not solve an infestation. The gnats actually hatch in the GnatNix layer. However, he GnatNix layer does definitely slow the gnats down.
Currently, my anti-gnat regimen is to use the layer of gnatnix. And, also spray the surface with a spray bottle filled with 11 ml/l Azamax/water a couple times a week. As mentioned, this does not eliminate my gnat tribe... just keeps them under control.
