I use a service that tells me the questions people type into any search engine in order to be directed to my website. I can't tell who asked, just what they asked. This morning someone, somewhere in the world asked an interesting one, "how to cultivate orchids beneath fluorescent lights". I haven't answered that question anywhere on my site but since perhaps others might be wondering, here's the answer. Standard fluorescent bulbs just don't have enough intensity, or the correct spectrum, to keep an orchid healthy and blooming long term. You might succeed for a while, but long term the orchid is going to need more light and the correct light spectrum. There are however lights made for aquarium use that will work fine for orchids. The most expensive is a VHO inflorescent ballast and bulb, probably several bulbs. These normally come in 110 watt bulbs at four foot lengths and can be purchased in a daylight spectrum of approximately 5600 degrees K. Not cheap ($300 or more) but they will work great. If you can keep coral alive under them, you can keep orchids healthy as well. There are also extreme high intensity lights called metal halide but I would not recommend those due to the excess heat and price There is another form known as a "compact" light that is substantially less expensive. I've got two of these strip lights on my living coral aquarium (well, the one that is about to have water in it) and they are quite intense. Each bulb is approximately 65 watts and you can find nice hoods on eBay for $100 or less that will hold up to 4 bulbs. These hoods are not only effective, they look descent as well. Many coral reef aquarium keepers now use these with great results. So again, these will work fine for orchids. They are cool to the touch and put out a great deal of light. Just make sure you buy "daylight" bulbs. The equivalent intensity would be similar to lightly filtered light outdoors. Although my aquarium is now ready to go (not filled yet), we've kept living corals since the early 1990's with great success. I just have never set up the aquarium since we moved here. But now the grand kids want fish and coral to see again! Better get started. Now, maybe the person who was looking for that information on the net will look at UBC!
