T5 light for phals

[silken]

I have these exact fixtures although I always make shades for them. I grow some of my Phals 8 to 12 inches under 1 of these with a shade to reflect all of the light on the plants. They are fine. Just introduce them slowly if they had a lot less light before and keep an eye on them. Some of the ones that have pink or purple flowers get purple pigment in the leaves but that is fine.
