hey thanks alot guys, it completely makes sense. i decided to pull apart the rockwool cubes and put directly into hydroton, same with the ones in peat. and now they are about 4 weeks in and the ones that were in peat are twice the size of the ones that were in rockwool. i dont know but in my opinion i cant say im a fan of the rockwool. i've heard of those rapid rooter plugs, have you guys used them for hydro, and how do the compare with rockwool?
