IMHO, White light is a subjective term. That being said, when I think of white light in this context, white light is referring to broad spectrum, harmonic rich, homogeneous radiation in and around the visible spectrum. I also think that "good white leds are so new and unproven/misunderstood...

Nice!!!! Very nice!!

"gap" or "hole" (rant) referring to the supporting documentation, not you're analysis or explanation. You're analysis has always been good. Misunderstanding.........No editor here either. http://www.allflexinc.com/flexible-printed-circuit.shtml

Oh no, I would only do that inside my Tardis. http://en.wikipedia.org/wiki/TARDIS

Yupers, at 450 a pop, $900 total for my 3x3, it looks like the HML is going to win out. Not to discount the allbright, because I really wanted to try it out. My latest HML is roughly 60% nw and 40% ww 9 XM-l's and 9 XP-G's running < 90 watts. IMHO the HML's obviously outperform everything...

Cycloptics is about to go commercial with their luminaire. It ain't cheep. About $600.00 a pop. According to them it will take 2 fixtures to cover a 3x3 tray. Excerpt from email with Cycloptics. So in my situation the initial purchase price is a wash, led vs Elite Agro. Multiple base legs...

I'm not a led whore, I'm just a whore. What leds bring to the table is better spectrum and less heat. At a minimum, if you live in a desert climate, the savings in AC is more that enough to justify the higher price. (I build my own fixtures at a cost of about $2.00 a watt.) In my situation, 400...

^^^^^ What he said!! Though, I didn't realize the huge leap in efficiency, if this is true........ That would mean 300-400 watts of led (or less) replaces 1k of HPS. If I had the money: (simplified!) Turn the led/diode into a transistor. Control the phosphors with the base. Treat the spectrum...

With Sativa leaning plants over about 6 runs, they did not adapt much or as much as I would have liked. Though this was a limited test with one main mommie, I would say that there is a median or center for a given strain and to change that median may take quite a while at least with the strain...

Interesting concept. You feed the girls a reasonable amount of a complete diet and they do just fine. You over feed and they turn into fat gluttonous picky bitches and/or they are squinting their little eyes and can only take advantage of the blue and red? To me sun adapted plants get fed past...

Ya, the pink light tends to make the plant puke up flowers. LOL Interesting study. The chart on page 4 is of most benefit. http://www.cycloptics.com/sites/default/files/Utah%20State%20Elite%20Agro%20315W%20Spectral%20Characterization%20Study.pdf

That is the premiss in supercropping. Supercropping with light??? No direct injury?? No recovery period????

The tortuous, this is because of the more efficient use of available resources. Bud formation takes much longer than sun/light adaptation and there is always the chance of destroying the mechanism, by running it a 100% or more. Now there could be a catch, if the machine is run at optimal this...

Think peaks and valleys. Hmmmm It would stand to reason that any biological system does not run well at 100% all the time. When we design machines, we always over engineer for the average load. (most efficient rate of production) Who makes bigger/better buds, the tortuous or the hare?

We're about to find out. I just put my shade adapted plants under the HPS. I'm hoping it will make them really bulk up and hammer the flowering response. From previous experience, I'd say it take 3 weeks or so to fully reverse shade adaptance, based on what you have said and my observations on...

Thank you kind sir!! That was exactly what I was looking for. I really like the way that you can pull this off the top of your head.

SDS, seeing that you are so well versed in plant biology. What do you think about thinner smoother leaves under white leds, opposed to HPS or discrete wave length leds or PLLs? Thinner leaves=more efficient????? Less biomass to support???? Thanks, in advance....

The leds are top quality. Full stop! The drivers are the best made. For your space, less than 200 watts and less than $500.00. Plus your time of course. Now to what spectrum????
