footcandle
 

Okay i just bought a rack and mounted 2 t8 lamps on it(4bulbs). I found an article that says the t8 32 watt bulbs give 500 foot candles at 12 inches per 2 bulbs. My 3 orchids all have flower spikes on them at the moment and i was wondering to get 1000 footcandles is that 12 inches from the top of the flower spike, or the green leaves of the plant?

Not sure about any of that, but bumping you back to the top! :)

Thanks :) yesterday on another forum i was told its to the top of the leaves and not the flower spike. And to arrange the flower spike around the lights. so here is a pic of how i set mine up

Very nice. I'm also toying with the idea of lamps, but need to research that a little more. I know nothing about it. That's one of the reasons I was drawn to your post. Hopefully, more answers will follow. :)

10 to 12 inches away for your phals should be fine. What is the other plant in the photo?

its a pacific heat oncidium. Here r some better pics of it.

Those flowers...WOW!

Your oncidium intergeneric looks like a Wilsonara to me. I would say leaf tops no more than 4 to 6 inches away from the light if I had to take a guess.

yip i guess the full name would have been better lol

Wils. Pacific Perspective 'Pacific Heat'

That is what I thought it might be after doing some searching.
