| I've had good results growing most of my orchids under compact flurorescent aquarium plant lights, such as those available from Aquarium Hobbyist Supply (sorry, I can't post URLs yet, try google). They are more expensive than regular "shop-light" tubes that many people use, but they produce a better spectrum for photosynthesis.
The only problem I've run into is to forget that many Paphs and Phrags need a few months with longer dark nights in order to induce flowering. It's easy to just put the lights on a timer and forget that. Also, the tubes are expensive and only last about a year. |
