Turtle...

I actually spent some time reading up on those via the link you gave...

Not bad lights actually.

But very non versatile. ONce the seedlings pop out and start growing, is when trouble can / will start for these FIXED POSITION lights.

FOr CFL to work, you need to be with in inches...like at the most, 2" from the plant top. What are your plans when three plants grow twice the size as another?

Think about these things.

If you buy a fixed position lighting system, you eliminate all hope of placing lights in strategic positions for maximun effect, later on when its needed.

These lights would be great for same strain clone fields......but their lack of versatility would prevent me from going with these if I were in your socks
