I use the 1" rockwool cubes and then surround that in a netpot with hydroton. So far it has never failed me in E&F and DWC. I also use rockwool to root my new clones in which makes transplanting them into the netpots with hydroton very easy. I have heard people say that rockwool isn't very good because it holds too much water but I have never had that problem. I have also only used the 1" cubes not the really big ones.

I would think if you put a newly rooted clone into a netpot full of hydroton, it would not have much of a base since the hydroton is rather large balls, there is a lot of room for movement. But that is pure speculation. :jointsmile:
dejayou30 Reviewed by dejayou30 on . Rockwool pros and cons please I tore my rockwool apart to see how the roots looked and feel my plants may be better in direct hydroton. I use a drip circulating irragation system 3 times 1 hour each feed per day. My rockwool looked very slimy and unhealthy but maybe i am wrong any help out there? I know if I use hydoton without the rockwool I will need to feed constantly right? Rating: 5
