Phals and lighting

[jfknigh2]

So, i have been trying to research this all day and finally decided to just ask the question.

I have read that best fluorescent bulbs to use are the T5's with the T5 fixtures. However, there is a lot of diversion when it comes to which ones to use. I have read to use 6500k in sync with the 3500K. And some have said just use the 6500k. What is your opinion when it comes to using these with Phals? Also, how far should the Phals be away from the lights being that they are a low-light orchid?

The reason I want to use the T5's is because I know that I will eventually want to get more orchids of varying genus and species that will have different light needs and the T5's will allow for growing orchids with higher light requirements.

Thank you all in advance!
