Thank you Franck,
You're technical expertise wowed me. Right now I just go with a
mix of flourescent cool white and warm white tubes in one growing case,
Metal-halide and high pressure sodium lamps mix in another growing
case, and a smaller metal halide supplemented with new (experimenting
with) compact flourescent bulbs. The light may make up in wavelength
imbalance by its intensity. My worry is cost in utilities and heat
produced, especially if I have to expand. It also appears the bulbs are
weakening. This was apparent last winter to me about a year ago when I
did replace them. I may opt to go compact flourescents or T3/T5 bulbs
all the way.
Bonaventure
