Growing sponge
 

I'm planning to put up some hydroponics system and I thought that I could use same kind of sponge. Before I have used also rockwool, but it has problem with scale.

Has anybody used growing sponges or foams?

I found the growing sponge by Grow-Tech. I guess it was called Cellular Rooting Sponge or something. Has anybody experiences with it?

There is something called "Oasis Rootcubes," It's actually a foam even though it looks like rockwool cubes. I have not tried it yet, but probably will thee next time I need some cubes. I am sure it's sold in large blocks also. I'm also not sure how you intend to use it (just for seedlings etc..), or what type of system/s your planing.


P.S. Do you have a link to the "growing sponge by Grow-Tech" (with prices)?

I'll just put plants grow inside it at first and water it. Nothing special! I don't have some much possibilities at the moment. I thought maybe I I'll be able to grow in side it at least half a year. But that's the reason why I need some information about those sponges.

So if somebody has any experiences with growing sponges, please share.

seesm it just makes it more complicated, why not just go with some grotan or even some gravel from a parking lot? i like re useable cheap stuff in my new green house were switching to good old fashion 3/8" rock. $15 dollars a cubic yard or free at the rivers edge.
