Thanks, Dun!
Technically, I guess there's really nothing wrong with the lighting. There is some part of my brain however, that likes the idea of switching to T5 HO, mostly for the increased lumens. Now that you've really got me thinking about it, the 2', 2 bulb strip that I have over my grow rack is 4000 lumens total output, whereas each of the bulbs (2 of them) over this terrarium are 1750 for a total of 3500. Not that big a difference. Given that the lights here are much closer to the plants, and the fact that if I got a T5 strip that was the appropriate size for the little 10g terrarium, I would probably be losing out in the long run anyway. So I guess the lights will stay as they are. Sweet. I think you just saved me a bunch of money, Dun!
