Hello, and thanks for reading. I have 6 pure sativas in a 2x3 square foot size and a good reflection. I have used 6 vero 18 cobs at 5000 k 70 cri 100 total watts 16000 lumens aprox for the vegetation phase.
The two first flowering weeks, I used the same leds but I use 200 watts so aprox lumens according to the datasheets were 29000. (to avoid too much stretching cause this strain does it a lot)
The third week of flowering I added 40 more watts in 4 cobs vero 18 3000 80 cri. Aprox 8000 lumens more. So at this moment I have 29000 lumens at 5000k plus 8000 lumens at 3000k total lumens 37000 total watts 240.
Plants are happy and all is going well
From now I have 5 more weeks to come (early sativa) and two posibilities:
1) Keep using the last configuration until the end of flowering
2) Use 100 watts of 5000k cobs...16000 lumens aprox plus 100 watts more of 3000k cobs. This will be according to datasheets about 16000 lumens more (these are 3000k last generation veros...more efficient than the 5000k ones) Total 32000 lumens. watts 200
Resuming:
1) 37000 lumens (29000 5K /70cri) + (8000 3K /80cri)
2) 32000 lumens (16000 5k /70cri) + (16000 3k /80cri)
Also I have the posibility of add 10 to 20 watts of far red 730 nm leds when stretching phase stop.
Which one of the options will be the better in your opinion? and..will the add of far reds change the posibilities?
Thanks for your attention and best regards from the spanish Pyrenees.
