Re: [APD] hydroponics lights ?

I have used metal halide bulbs with great results. I also lost several
gallons a day to evaporation and my electric bill went through the roof.
I was running 2 X 250W MH bulbs on a 55 gallon.
The mercury and sodium lights don't have as nice a spectrum as MH, but
as Tom Barr will tell you, plants are not that picky about spectrum. I
just don't think they look as good.
