Also, could you explain the thinking on the 2nd point, I mean if LED's are weaker at flowering wouldn't you want MORE red????? :wtf:

:thumbsup: I ask because I'm interested...LED's have some serious safety advantages it seems
I've run tests under blue-dominant LED lighting and have found no major difference in mass, just in trichome density.

The ratio I cannot discuss too much as it's a result of my company research. Needless to say I emulate the sun as closely as I can with the few wavelengths I use.

You want a good deal of red, yes, but you want blue for bulk production, and also blue penetrates better than red. Blue light is what is responsible for powering a majority of growth processes. Red is responsible for powering flower development. Notice how the blue poor panels tend to produce fluffy buds in most grow attempts? Once you put major power like 300w into the equation that's not too much of an issue but still part of the problem. My fresh pre-trim stuff is hard. I can thump it and it makes a decent sound against my fingernail.

The safety advantages abound, indeed. Near-nil IR signature, no UV (none required with my design anyways,) higher efficiencies at lower power, no burning parts, safe to spray treatments without fear of burning plants while lights are on, less stress on your electrical system due to lowered energy requirements from both lighting and through reduced cooling requirements.

Other advantages include customizability, ease of installation, compact size, some models lack external ballasts (some lights require them,) lifespan, and quiet operation. Then power savings are nice as well.

Oh, and avoid the hype of 90w = 400w HPS - that's only true for the vegetative phase. When you hit flowering, minimum 200w to match 400w HPS.
