Best led for 2x2,5?

There wouldnt be any gain with co2 bags. You need to seal your grow tent very well and use proper equipment.
Imho a 260w even if dimmed down is wasted in that space but it is just made of 2 boards so you can always buy one more 135w kit in the future and dim it down.

@diyled probably has a fixture for you using the same diodes used in quantum boards v1 but with a better spread of the light.

(I am using 150w of cobs in my 2x2 tent) 200w are probably too much

EDIT: 135w kit comes with a "A" version driver, there is a screw on the driver to be used to dim the light. I would suggest you to get a watt meter

I wish there was a board with 2700k lm561c or lm301b and with 10% 450nm osram, xpe etc. It'd keep costs down by using just 2 diodes and the extra blue would add in what 2700k is missing. Most multi diodie boards go over board and use everything but the kitchen sink. Just to get more or less the same spectrum two diodes could.

Isn't the growmau5 puck from chilled led pretty much the same as that? I'm sure cutter could make that for you but idk what his minimum is for custom work

Edit: wait I think it has 660nm supplement not 450

I'm not convinced that would be of any more value than straight 3500k or 4000k. But it would be interesting to see a real-world comparison.

Not convinced? Imagine your looking at a 2700k spectrum chart. Now imagine only the blue spike moving up. Bc that's exactly what would happen.
