No light meter. I tried to use my digital camera, but couldn't find any information about the light fluence at the specific f/stop I used. First Ray's orchids has a page with some of that info, so I "iterated" based on the data his table provided and my camera's settings. I seem to recall the reading was on the high end, but didn't seem to be out of range for the plants. The deep plum-purple coloration on their leaves concerned me, so I thought I would check in with my OB "peeps"!
