Growstones

[J Teezy]

So it seems growstones are the new thing over hydroton. Anyone that is using growstones does it wick water back to the substrate like hydroton does?

Apparently so...

I have been seeing them more frequently of late. However, Hydroton is still there and strong.

Not sure about the water part, actually. Maybe someone else who knows will see this thread and comment.

Im hoping it doesnt wick like hydroton. This demo shows how it absorbs it which would be great for humidity, i just hope its doesnt wick like hydroton

Tough to say, haven't found anything yet about it actually absorbing water. Seems to me it would work a lot like pumice, it will hold from being extremely porous but not absorb it. That is only a guess though.

it most likely will wick water. if it absorbs it, it most certainly will wick water. remember, even natural, smooth rocks wick water to some extent.
