received today, was running 2 300W burble mars hyros...UPGRADED to 2 3500k Cobs, will have 2 more coming soon. Thanks again to BigSmO at Cobshop.net for educating me on the different cobs and explaining things in a manner I could understand. Also, Love the fact that you can take pictures and look at plants without turning them off , unlike the burbles
..can see for quick diagnosis etc.
