HPS vs. Induction + CFL flowering comparison
"Photon flux density actually is a measure of the rate of flow of light in a given period of time. It is measured in Lumens."
No, it is not measured in lumens, at all. Lumens is weighted at 555nm. Photon flux density is measured as umol/m^2/s-1.
"Also, published Flux Density rates of various light sources do not take into account the direction of the flow of photons"
Photon flux is a ray, and as such, straight line emissions from the source, and reflection from a reflector happens at the same angle at which it strikes the surface.
"With this in mind, a well designed T5 running very cool and being able to be very close to its target can actually be more efficient than a "hot" light that has to be many magnitude further away"
Can be in theory, in almost all practice, it fails. Also, do you understand orders of magnitude? Your use of the word hints that you do not.
"I may be new to growing, but I know my science."
Speaking as a research director, your science is totally flawed and incorrect.
Time to put my own hip waders on, it seems.

So until it's been hashed out in terms my ignorant ass can understand,..... I've got my waders!
not trying to start a shitstorm,.... just trying to learn a thing or two from it all.
With any luck my girls will benefit from it..... and if not,... well they aren't any worse off than they were before this thread!:greenthumb:

Yeps, lets see how vanduction experiment ends. He simply put under test claim of half wattage of induction lamp equal to HPS.
For the moment it seems result not confirm such claim, but Ill wait grow finish before stating it. If result is negative, then it would time for discussing about how much light each option emits or what would be the right amount of induction watts to match results of a given HPS.
Good job, vanduction :thumbsup:

Some of them, noticeable amounts of yellow. By placing white and red T5s intercalated 1:1 or all at each side, for such number of tubes there going to be little difference between areas of the grow. Yes, different spectrum on each side, but not extreme differences at all.
But I think we are highjacking thread with this question, why about opening a thread on the topic?
