Hi farm,
I am planning on building a led setup. But i cannot decide on the spectrum i want to use.
Right now i have 20 3000K 90cri, 6 4000K 80cri, 2 6500K 70cri cxb1830.
I am going to use 18 of these cobs. I am going to place them on 3 bars, 6 each bar. For inital veg i will use 1 bar. The total draw of each bar should be around 150watt. I am driving them super soft at 700ma.
I am torn between 4 different options.
Option 1
Use 3000K all the way thru, don’t add any cool whites.
3K-3K-3K-3K-3K-3K
Option 2
Use use 12 3000K and 6 4000K divided equally to each bar.
3K-4K-3K-3K-4K-3K
Option 3
Use 12 3000K, 4 4000K and on the veg bar instead of 4000K use the 2 6500K.

3K-6K-3K-3K-6K-3K
Flower bar
3K-4K-3K-3K-4K-3K
Option 4
Use 10 3000K, 6 4000K and 2 6500K. Two of each on the veg bar.

I like a little blue myself, i was supplementing my blurples with 6000K led bulbs and getting good results. Plus i didn’t like the way my plants elongated under 3000K 80cri leds.
What is your experience with different spectrums?
I am leaning towards option 4 but i just cant decide for sure.
Which one would you choose?
