You will need atleast 1,000W of COBS to light that space for flower.

I dont see how you will achieve that with 9 cobs...I think you will need atleast 18 high powered cobs running @ 55w. What cobs you plan to use?

If you ran them at full blast you would probably be producing enough light. But the spread would be bad with only 9 cobs. I still say you will need 18 cobs to light that space minimum.

Ah I misread your original post, you did say you are building 2 x 9 cob fixtures.

That would work perfectly for 50SQFT

I would run those lights @ 50%-75% power for maximum lifespan and efficiency. You can bump the power up if needed. Let us know your par readings!!!

That's the plan have a lot of power but run them softer. I plan on expanding to 10x10 once I get a couple runs under my belt
