That would be what I'd buy. 3500k is Whole cycle. I'm saving up now and hoping the prices start coming down.

I was planning on getting 2 300w cxb3590 six cobs, to cover a 3.5 x 7 room. I'm thinking 9 cobs for 4x4

12 @ 50-65w each would be good.

you can do a 4x4 with as little as one 550W cob, or 4 150W cobs, or 9 70W cobs, or 16 40W cobs, or 25 25W cobs, or 36 15W cobs, etc etc
more cobs=more efficient and generally more uniform coverage
i like to use squares in squares (4,9,16) but thats jsut a preference. 12 works too you just space them differently in each direction.
9-16 prob best for a 4x4

yes it depends on size of chip. i wouldnt recommend the same chip for a single 550W cob as i would for 25 cobs at 25W each. every manufacturer makes different size chips
dont even bother with cree, theres no justification to use them at their current price point when chips under $20 do the same thing

Theres a thread in the auto flower sectin where a guy has 4 cobs totaling 220w in a 4x4 and hes aiming for a lb from 4 autos. I'm running 6 @330w in a 2.5x5 closet and about to pull a lb from 3 autos.
I think a lot of people are running more light than necessary.

From timbergrowlights:
There are a few different ways of achieiving 600 watts with COBs passively cooled. You can run them at 50-100 watts each, depending upon the brand, and get fairly consistent results. To cover a larger area, I generally recommend the Very based lights because the Vero29 COBs are very efficient at higher wattages (100 watts/COB), meaning you need less materials to build the same light as a Cree, for instance, that would need 2x the amount of COBs (12 Cobs @ 50 watts each).
I find the Vero to be a better value when covering larger areas because the capital expenditure $/watt is much less

Do autos really produce that good of numbers ???? Got any pics ?
I'd love to see LOL
My absolute best so far, Ever, off of any plant is 4.75 ounces.

Just pulled 6 zips from this topped auto cheese.only 20" tall but 36' wide. Took 6 hours to trim
Expecting much more from this pair of auto Amnesia. They're almost 6' tall now.

I'm a noob too. This is my 2nd grow. First go under 400w HPS I only got about 7 zips total from 4 plants. Discovered I'm not cut out for organic soil. The Cheese was my last soil grow. Coco from here on out. That's what the Amnesia are in.
I give all credit to the 6 individual COBs hanging in my closet.
