Hi,

How much light is needed for growing Phal's and Paph's? I have a 24 inch 17 watt flourescent light (supposed to give off 75w worth of light) on my plant stand and I wonder if that is enough. Does anyone know the amount of wattage it takes to make the 1000-1500 footcandles required for these orchids? The bulb is supposed to be a grow light...it has a purplish glow to it. Would a broad spectrum bulb be better? Also, how far away should the lights be from the leaves? I would appreciate the help. Thanks,
Andrea
