Of all the 50 things I read through trying to figure this out - this

I was doing some confusing reading on this a week or so ago. Lots of

later I've decided to go with one Chroma 50 and one Chroma 70 in my 2
tube shop light. The chromas have rounded wide band colors and they
overlap well for supplemental plant light, and like Ray said they are
lots cheaper than the Gro-Lux WS tubes.

Another point good for a debate, but I like the GE "Sunlight" bulbs
(Chroma
50) or Sylvania "Sunstick," as they have a higher intensity than the
"Gro-Lux" types, and the spectrum is really good, while only costing a
buck
or so more than a cool white.--

I just bought a Hydro Farm orchid cart (used).

I think the bulbs are no good (maybe ballasts, too!).

What kind of bulbs do orchids need to supplement natural light
indoors?

Used to live in a sunny house, great windows for orchids.

Moved to a house in the woods. Dim every day of the year. The orchids
hate it!
