Opie, I believe it was the "NEVER USE ROCKWOOL ... EVER" part that got my attention.

Also I think you might be surprised by how many production growers are here from time to time.

BTW ... I really liked your stadium grom pics. I am a scrog grower and love the increased production it gives. Does away with all the light pnetration issues. Also great for when limited vertical growing space is available.

Stinky brings up a good point regarding the disposal of the rockwool at the end of the grow. That is one reason I prefer Pearlite/Vermiculite combos when possible. Also the Rockwool cubes (4" or 6") are not for very long vegg periods as mentioned.

I have found it is almost immpossible to over-water when using Rockwool unless you have the cube sitting directly in water. Excess water will drain right out the bottom. I water once a day.
