Hello fintuckyfarms,
I cant say I have tried it, and this is the first I have really heard of it. But I did a search to see what it was, and this is the stuff I found Grow stones. First I'm not really a fan of growing medias that are reusable anymore. Simply because it's not worth the time and effort to clean and sanitize it for reuse. In small quantities that's fine, but not when you have 20 gallons or more of it to clean, well at that point it just takes too much time for me.

With that said, after reading about the growstones. Well I'll start by saying that it's nice that the company is recycling the glass that would otherwise just be in the landfill. However I didn't read or see anything to make it worth the price to me. It seems to have all the same properties of lava rock, but cost about three times the price (or more). I found a retailer they listed, and the stuff costs $30 for 1.25 cubic feet worth. That's not even enough to fill two 5 gallon buckets. Decorative Lava Rock on the other hand is readily available in most any garden center, and runs $3.68 (at Lowe's, as well as Home Depot) for 1/2 cubic feet. Or in other words 1/2 cubic feet x3= 1.5 cubic feet for about $11. I think they mostly focus on it being a recycled product, and that's nice. But I'm not going to spend three times the money just to be able to say I'm being green.

P.S.
There were a few people a while back that were experimenting with using Polymer water absorbing crystals, but haven't replayed back since.
