metal halide spectrums
Posted 03 February 2007 - 03:46 AM
on that ebay listing it says the MH globes come in 10,000k , 14,000k and 20,000k spectrums for plants and marine aquirums. im just wondering if anyone knows what to expect from the different spectrums and which would be the best option for keeping my mothers alive?

if your only looking at something for mothers, its wont make a huge difference. Althought the blue is best for vegging. So I would probably shoot at something like the 14000 or the 20000 as it contains more blue, and since your not flowering. the Red isnt important to you.
olor temperature, or degrees Kelvin (°K), is a number assigned to a bulb to describe the color of light it emits. The lower the number the warmer or more to the orange/yellow side of the light spectrum is its appearance. The higher the number the cooler or more to the blue side of the light spectrum.
Here are some °K examples and their corresponding color descriptions:
white with blue

Wise men talk because they have something to say; fools, because they have to say something.
We can easily forgive a child who is afraid of the dark; the real tragedy of life is when men are afraid of the light.

If you go to the hydro shop and ask for a MH retro to suit your ballast say 400w or 600w, that is all you will be needing for the blue light.

I am currently running a 'SLAVANA' 400W Metal Arc (M59) R m400/c/u bub........... She's sweet for vedging. I believe it is in the 10000K (white with blue) as it kicks of so blue before toping of white.

Don't seem to be cutting it with the quality? You get what you pay for? There cheap as there philosophy is to "be the biggest , cheapest on-line hydroponic suppler".
If you want to play with 'spectrum' play around with the UV (blue) 5,000k - 10.000k.
