    Cobs are definitely the way to go as mentioned above, however rather than buying prebuilt fixtures, why not just build your own and save over half your money?

    Here are a few pics from my last round.. The Cob rig pulls around 600watts on 9 Citi 3500k.. I should have numbers in a week or so.. I also had a single 135w Quantum board over a 1 plant.. i will have numbers for that aswell.. The rest of the room held 3 DEs for 3K..1 DE per 4x4 area which is really just over kill as i dont run CO2..

    So my plan is to replace the DEs with 600watts of Quantum Board per 4x4 and get close to the same yield.. I normally pulled 1 to 1.5 per light.. Nothing epic on yield but it is what it is.. Below are some shots before chop..

    Good job already having COBs going. QBs are nice too but never in stock.

    Those are the 1818 on 133 bin fin sinks.. Powered by 3 - HLG-185-54. I think i put them 1' on center.

    4 QBs at 600W should be pretty similar results to that 1818 rig. will come down to how uniform you can cover with them

    Details on the QB rigs..

    Each lights holds 2- 240-1050A which when turned up will hit 300 to 305 watts at the wall for a total for 600 to 610 per light.. All heatsinks are slate 2s. The frame is cut to a 3 x 3 layout.. The boards are spaced 11" from edge to edge.. And when they are installed the outside boards will be close to 11" away from the wall.
