I'm in the exact same boat, I have a 29 that came from a garage
sale with two incandescents. I stuck two 20W fluorescents in those
sockets - the ones meant for light bulb replacements. The light
was too concentrated in the middle and the plants didn't do
that well. I put them in a hall light fixture.
Next I tried a single 20W chroma 50 abd the plants took off - too
well - I think all that blue was stretching them a bit (blue elongates,
red makes more compact) and the red and brown pigents were diminished
in various plants so I switched to a 20W "plant and aquarium light"
which brings back the red/brown and less elongate growth but is too
dim in there - plus I'm getting a trace of brown algae. Under
stronger light this would be green and the endlers livebearers
in that tank would eat it instantly.
So, Next I think I'm going to try compact fluorescents after discovering -
only 5 minutes ago that it's possible to get bulbs which tend towards the
red not just blue (6700K) bulbs.
I doubt it possible to find stuff as good as ahsupply.com or for as cheap.
They seem expensive on first glance, but regular hoods aren't much cheaper
the the difference in light is phenominal.
I'm thinking of using one "beast" and as many 13W red ones as I can fit;
if that's not possible I'll mix as many 13W red and blue as I can fit.
Plus, ahsupply answered my mail promptly. A rare occurence.
