Flower stage: 4" Rockwool vs 6" Rockwool Cube

More roots bigger plant.

The guy who said rockwool is a medium should be shot. It's garbage insulation loaded with crap from where ever they made it, China or Brazil. Forget rockwool completely, I again use dirt for sprouting seeds, frigin shit cost me more seeds than I can speak.

Was wondering about this question: If there were two systems which were identical in nutes, lighting etc. But the rock wool cube sizes were different would it affect the growth of the plant? would more root room promote a healthier, happier plant?

You must read grasshopper, and read some more.

Here is a bone, Look up homebrew's grows. he does some comparisons of Dyna-Grow and other nutes.
