I posted a while ago asking which type of fluorescent fixtures would be best for growing orchids, and many had the consensus that T5's would be the best. Alas, money is very tight, and I chose to go with my old growing setup, 4x 40 watt T12 tubes. I am curious how many of you are using T12's or T8's, and specifically what tubes you're using in your setups, and what orchids you grow/flower regularly. The specs of my current tubes are: 2x GE Daylight 40, 3050 lumens, 6500k color temp. 2x GE Kitchen and Bath 40, 3400 lumens, 3000k color temp. I have no light meter, but will be getting one soon, as I'm curious what footcandles this setup puts out. If you happen to know the FC output of your setup, that would be very helpful as well. I've done a lot of research on this topic on the web, but I can't seem to find anyone who gives the details on what tubes they're using; only seem to find people saying generic information about what they grow/flower. Specifically, I'm curious if anyone out there grows using T12's or T8's as their primary source of light, and is able to flower any type of Catts (mini/dwarf or otherwise) using their setup. Thanks in advance for any input/advice. -Tim C.
