Has anyone kept up to date with knna's DIY led work?
Wanting to know what the most recent word is on wavelengths and ratios for 1 veg light and 1 flower light.
Been reading up after you mentioned him in another thread; the most recent info I can find is
here and
here:
"6) Red, 660 nm and Blue 460nm are the only wavelengths you need for optimal growing?
So far.
Weezard, Thank you so much for your interest. I told myself I would not use another UFO again and I’m just about ready to start a new grow, so could you also tell me what the best approach using LED’S seedlings is. I noticed I has some serious stretching that occurred when using the 90w ufo same spec has my current 120w Ufo tri-band red, 660nm,blue 455nm and orange 630nm with 7.1.1 ratio.
Best approach?
More blue!
7:1 will stretch them to death.
Your R:B for seedlings should be closer to 3:1.
More blue = tighter internodes.
Overall I’m content with my results but I know there is a lot more to uncover using Digital lighting. Thank you for your attention in this matter of mine
Then go to 5:1 for flowering and you'll be even more content."
Weezard really seems to know his shit, the second thread is pretty technical.
