I am always interested in information.
I have seen these displays at my local hydro shop....the counter help couldn't tell me much about the product line AND there was no product information at the display.

Currently I have more opinion than fact. Conceptually the whole idea makes sense... then again at one time it made sense to believe the earth to be the center of the universe.
I will with hold judgement till I have other growers verify the claims. I am not willing to experiment with my grow just now.

The Grow University seems pretty cool. I just signed up for a class...

Check out www.raw-Solubles.com for some more information on those products :)
