As specific as possible. That was exactly what I was thinking. We all know Blue=Veg Red=Bloom. But what is really the most ideal? And then what about seedlings? and cuttings? And early Veg? And late flower?
I know UVB can be great for late flower. IR is supposed to reduce stretching, should in be used it early veg? What about UV/IR for cuttings, should they be cut out completely? How many watts is too much for a seedling? Etc...
Yeah, very interesting... I hear different things about UV/IR from people, haven't looked into it enough to make up my mind.
The UV/IR wih cuttings is very interesting too... no idea there... I guess, if no info is specifically available we have to look at exactly what the light does, and what the plants doing at that stage, then guess at what they may do together. I have a UVB bulb I was thinking of playing with... I use it for myself (vitamin D deficiency) and will be purchasing a multipurpose UV in the future... and an IR lamp is also within my budget and use ( I love a good heat lamp... we get little sun where I live, and it's cold).
This is now on my list of near future experiments (my other involves citrus acids for growth)
Or the seedlings... hmm... in my experience it has been the more the better so long as intensity and heat were conrolled. I put 20+ watts CFL right down by my seedling ( like 3 inches?... I sprouted by letting the hood of the clamp lamp sit on the soil creating a dome, and raised it slowly and proportionally over time til I hit the "sweet spot" for me (best coverage and intensity).
I am often curious about minimums... how many watts do you need to sprout well. How much water per plant mass? etc etc
