Old T12 40 Watt 4ft 2 light set up. Anyone Use these?

Has anyone used older T12 2 bulb 4ft setup? They are growing the plants fine, but I am wondering how large the buds are going to grow. One of my plants is about 3 ft tall. I would like to hear if anyone has used these flourescent lights with success. Thanks

not very much, tubes dont work with flowering very well unless you add a bunch of sidelighting, got any pics of the plants and area?

yep i used sum years ago, not to bad for veg but very pore for flowering, you are alot beter off with CLF's or just add as meny clf's as you can get.
Good luck.

I bought some CFLs today at home depot with some cheap reflectors. Thanks
