I'm done with Igrows. My last round was 1/2 pound under a light in a 4x4 space. I can't run a scrog as there is NO penetration into the canopy, even 8 inches from the bulb i'm getting larf that can't even be trimmed. When I try to run colas, I can't get anywhere near enough stretch to produce, and the lanky/stretch strains just stretch even more. The plants are frosted but nowhere near the stickiness of HPS.
They were doing pretty ok in veg (they kept up with 600w bulbs just fine), but in veg and flower both the leaf petioles were 2-3x longer than they are under any other light source, which I've always understood is the plants trying to move their leaves from areas that are too shaded. I'm using 315w CMH in veg now and they are crushing all, I definitely recommend those in any stage if you're looking into alternative/efficient lighting.
I put one igrow over my buddies pool table, makes a really cool orange/purple hue that is much more fun for billiards than plant growing. I still have a couple lying around, might try flipping one upside down and turning it into a glowing coffee table with a frosted glass top. Definitely not something I would recommend to my friends to grow under - I don't even really want to sell them at half price b/c I don't think they are even worth $600.
