here are some pics of my most recent led experiment. I know, I know, I'm back to my trusty hortilux hps- nothing can beat it, but this grow was amusing. felt like I was 3 again playing with lite brites. I used 3 660 nm red 90w ufos, the one in the middle has the hid hut satellite system- 8 5w red-dosent give specs- bulbs from led grow-lights.com.3 45w glow panels.Lets just say just shy of a grand may not be worth it to some for about 2-3 oz per crop.But depending on your situation it may work for you.Bottom line is they do work, but expense, and well... expense is holding any real progress at bay.
