Lighting Cobs to replace 150watt hps

[autoste]

Hi all, I'm thinking of trying cob but only have 1m tall space,is it possible? If so what setup would be best, i have a heatsink and 2 drivers 30w silver ones of ebay.

Cheers

Best is to have 2 cobs at 25 watt each. 50 cob watts will outperform 150watts of hps.

Im not sure off the top of my head which driver, for 2 citizen 1212 cobs you would want something 72v or higher and 700ma. The drivers in a mars hydro would be perfect.

Thanks, I really appreciate the help.

Depending on your budget Id consider 1 HLG-60H-C700A and 2 citizen 1212s. In a space that small having the ability to dim the light could be very beneficial, since you wont have the ability to move the lights away from the plants if light is too intense. Also consider going with a higher K cob, like 4000k to help control stretch.

That's the one

Cobs are definitely the way to go, prices are steadily going down. So many advantages to a diy cob system. The biggest one i like that no one talks about is the color of the light, no more disco dance floor lights beaming in your face every time you walk into your grow room.

The visual color is nice but the spectrum is actually one of the bigger benefits vs a r&b.
