What are the rapid root plugs made of and what is the difference between them and rockwool?Does hydrofarm carry them?
avon211 Reviewed by avon211 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
