From DEs to LEDs

[greengrassgrower1]

Lets get this going. i will try to document my conversion from DEs to LEDs in my 8x8 grow area..

8 x 8 is a nice space. You'll need 4 units x 600 watts of COB. These would be perfect for your space. http://timbergrowlights.com/600-watt-vero29-v7-4x4-framework/

If you are in Canada, I recommend these by Par-Horta.

which LEDs will you be using?

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.

What model Citi are they? 1212?

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

Okay boss- now show these guys the quantum board rigs you just finished building.

Here are my newest QB rigs. Going to be used to light a 4 x 8 space.

That would be great. Those Cobs did awesome..

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.

those pesky leds are killing it! nice buds

im running 5 x 260w kits in a 4x8 so pretty similar.

Can't wait to see your grow with those badass QB rigs!
