I'll be transplanting Friday or Saturday.
For the first 20 years or so I ran strictly MH/HPS (t8 and t5 for seedlings) and since around 2015 I've also had a small tent that I've dedicated to my CLW Solar Storm 440. So this QB grow is my first foray into white light LED. Plan on using the QB as the center piece of a bigger light with integrated COB and some far red diodes down the road.
Possibly, but I've been at it for a decent bit now and it's so far beyond what I've seen before that I guess I engaged in some wishful logically fallacy by assuming that the difference might be directly related to the light.
You're definitely not the first person I've heard say that they're seeing noticably faster root development under COBs/QBs/strips. But I really don't know how that could be, so I hold no opinion on the matter.
say what? don't the color maps for qb's show a LACK of reds? Especially deep reds?
don't the 2700k have some goodly reds?
HPS lights have a huge red component. They are something like 15% IR alone. That's why they heat the canopy up - it's like a warming lamp at a restaurant.
I think they are good up to about 600nm, then it falls off fast.
ahh. if that's the case, then yea, not so goodly on the reds.
What are you using for UV?
