reflected footcandles

[VickiC]

Hi,
My question is not a "light bulb" question, so I'm hoping that I'm posting to the correct forum. Whatever the case, though, I feel sure you can help me with an answer.

My husband covered all of the counter tops and a portion of the walls of my orchid room with an aluminum foil type insulation material in hopes this would increase my T5s footcandle readings (sorry....I don't know the correct name of the insulation) . Approx. how many additional footcandles can I expect to have gained from the counter tops and walls reflecting light from my T5s?

Thanks in advance.....I would appreciate your help.
