Growing with Sand??

[Crispyfried]

Howabout growing with Volcanite? This is high iron fine rock, almost like sand, and you can use up to fifty percent in your soil mix. I have some but haven't used it yet.

Growing with Sand?? has anyone entertained the idea of growing with sand as a medium?? doesn't absorb water, doesn't absorb nutrients.. the roots can move however they want throughout the sand, just lyk rockwool... ideas? comments? now wat about the colored sand they put in those animal shaped bottles!!! then u can get a black light and make ur grow look cool during the 6hr night :rasta: Rating: 5

I read a forum a couple days ago around here some where that talked about volcanite. I do not think it can be crushed up superfine as it would not have air pockets and the roots may need more oxygen but I here it is good to use in hydroponic apps. I can not say I have tried it my self except to put on the bottom of soil pots to promote drainage. It made them a bit heavy so I stop using them. Just an experiment.

Is it heavy?

Yeah it's heavy but that's probably because it's been crushed up pretty well.

Hmm, I have never heard of using really crushed up stone, but there are a couple threads on this site that mention using lava rock which is the same as volcanite for a hydro medium in bigger chuncks where it still is porous enough to store air in the pockets.
