The coco is a brick that you have to put in water for it to expand.

New to Hydro Hello, I live in the caribbean, and over here we do not have access to rockwool.Right now I wish to start a Hydro setup, I could get everything except the grow media. So I have a few questions 1. If anyone knows this stuff named Oase's it's a foam like block that is airy and retains water very good.But I never heard or read about it anywhere. 2. If I cannot use that, can I use coconut fiber with regular hydro nutes or do I have to get special coco nutes. Please I need some help a.s.a.p. I Rating: 5
