Sandra,

That should help a lot. Most recommendations on the group are for one cool
white and one warm white rather than the higher tech bulbs. Start the light
about 18" above the plants for a week or so and then lower it 3" a week till
9" to 12 " above the plants.

Watch for other comments and opinions soon to follow.

Hello, I've been recently growing a few orchids(mostly phals) in my
west window, but lately their leaves have been turning dark, dark
green, the roots all still look fine, I'm just worried about the
lighting.
Anyway, I'm thinking about doing artificial lighting next week, and I'm
wondering if 2 40 watt daylight bulbs in a shop light fixture will be
okay?
I'm just wondering if this will be enough, I can suppliment this with a
few hours of shaded sun that my west window gets.
Thanks, Sandra
