Looking clean, green and mean there Mr Humble! Nicely done! What cobs and drivers?
Thanks for the compliments I appreciate that. I'm running 4-3500k, 2-4000k, and 2-5000k Cobbs with 2 Pairui lgsu 250-c1400d drivers from cutter. I running them without the reflectors since it's contained to let the light mix together. Here's a pic from today they blossomed overnight literally

What is up mfs and dfs lol. Seriously I have one simple question. I have studied up a bit and im sure i might know this answer but its better to ask for input before i cash out. I have a small 2x3 area. Will only 2 Cree CXB3590 driven at 1400 be enough to cover my area effectively. I know there may be some "dark spots" but will it be enough to get the job done. Im not trying to like rake in like hella meds just enough to keep me and my wife from shopping with these pricks. I dont have much money to spare either. Please help me out. Give it to me straight, if im being a cheap ass or about to waste my time just let me know. I might be able to get the 4 cob kit. (will that be too much light). Thanks in advance.

If there's any way you can afford it go for 4 COBs for that size area... You will be glad you did.

Would be on the low end for flowering, but a very efficient grow. ~500 ppf for 2 cxb3590s at 50w each in a 2x3. Should pull a QP minimum, and upwards of a Half on the high end.

Four would be better of course, and you could dim down actually if you don't want the full 928 ppfd in that area.

You wouldn't need that much for cooling purposes, I'm not sure how much we want minimum for fresh air for the plants though. I pump heat into the grow room still, house is too cool to get that ~80℉ we want under the canopy. But I keep the fan up for smell.

You can go cheaper if you source yourself. Or running slightly lower efficiencies. 4 x cxb3070 at the same watts as cxb3590 still puts a ppfd of 830 in that sized space. Or running cxb3590 at higher wattages, 3 x cxb3590 at 63w each gets that same ppfd of 830 for 189w through the leds instead of 200w with the 4 x 3070s. Lotta different options.
