Distance between light fixture and plants .....

[NeoNJ]

The Light Meter I have is an OMNI Light Meter. And it registers a consistent 5000fc (The light meter is on the windowsill, and the light fixtures are 18-30" above the light meter).

I have 3 clamp on fixtures - (1) with a 32-watt spiral CFL/6500k, (1) with a 26-watt spiral CFL/6500k, and (1) with a 40-watt spiral CFL/2700k.

The mounted orchids on the side walls are 12" from the light source.

Since the light meter is below the mounted orchids, I will assume the mounted orchids are receiving light levels that are higher than 5000fc. So I think I need to raise the light fixtures, lower the mounted orchids, or change the intensity of the CFL's.

Any thoughts ?
