Heard of it - yes.
Heard of anyone using them -no.

Their spidermite spray sounds like it might be worth trying.
Also their products for soil growing might be worth it too.
For me - I wouldn't use them for hydro

So if you go for it, please keep us in the loop.

I have a brochure and a web site for them... looks pretty interesting. Gro Rite Organics - Hydroponic and Earth Growing Nutrients I'm thinking of switching to this system... Anybody heard of this company? History? Experience with their system? Rating: 5
