Lights Used in Orchid Culture

[Ben Belton]

I germinate my seed, make spreads, and grow out final flasks all under double tube shop lights. You don't even need that much for the first 2 parts. Seed will germinate and grow to protocorms under almost no light. I buy the T-8 bulbs from Lowes that I believe are 5500K. My flasks and my hood are in my basement where it is not aseptic, but I have almost no trouble with contamination. The temperature stays fairly constant. It is only a little warmer in the summer and a little cooler in the winter.

Hope that helps. I do Phals too.
