Outwest, I too am curious to see if they can discourage or completely stop fungus gnats; I'm also hoping they could stop root aphids since root aphids cannot survive in sand (silica) which is essentially what growstones are made off I believe.
I am also curious to know if anyone has any experience or thoughts on using the "soil aeration" growstones in lieu of the "hydroponic medium" size. From one website the smaller ones can be had for $15.50 per cu ft compared to the larger size at $24.8 per cu ft. Considerable savings when buying larger amounts and their air and water holding properties appear to be similar.
I had gnats using grow stones 2times.
There goes that theory, thanks for the info gimp73.
