Heya all, and thanks again for the input.

As for my aquarium, It's fading at the moment. I run two 48" VHO and four 65w CF. To which all are over a year old. Issue has been too little income and way to many things going. Oddly enough though, the tank is showing a few improvments sence I lowered my attention. I've been thinking highly of switching to MH, However some of the laws recently passed make me think they may not be legal in the US much longer (See Australia, they signed the same UN agreements and are currently enforcing those rules, We on the other hand are currently ignoring them until some random future date.)

BUT,... Sence my last post I read MANY pages about L.E.D.s, Although they seam to be acceptable on the RED and BLUE spectrums and better on many of the PAR numbers withing those spectrums. Most of the ones that contain some UV are WAY over priced (resins are a protection mechanism from UV). Thus the tech is there, just NOT the "perfection" I would demand from them. MANY companies seam to sell fixtures that use LEDs at 1w or less, but we require 3w or more per bulb. 5w is optimum.

So, now I'm thinking maybe a 600w switchable, running a MH during growing and a HPS during flowering. Running on one of these 6 foot automatic light tracks (moves the hood 6 feet back and fourth across the room every 20 min). Mixed with an LED panel on each of the four walls. I believe this would produce the highest amount of usable light while still reducing the cost of all that lighting.

I'm going to read more about this UV/resins issue next. As I said early on, the room I plan to use has been housing iguannas for years. To keep them healthy I've been using a self ballasted mercury vapor bulb which produces insane UVA/UVB for reptiles to convert B12 (I think) to D3 and thus calcium to bone. It produces almost 12 spectral irradiance in the 320-400nm range of UVA. I'm thinking if UVA really causes the plant to make more resin. Maybe I'll suppliment UVA during flowering with one of these.

I know I'm going way out of the accepted "norm" here. But this is all very interesting to me.:thumbsup:
