t5s for veg

How much t5 lighting for an 5x5 veg tent\room?

A T-5's footprint is typically whatever size the fixture is. So if the T-5 is 2ft x 4ft, then your footprint covered is 2ft x 4ft. It's not like a MH or HPS bulb that has a footprint greater than the size of the fixture, the CFL's don't produce enough. So If it is a 5x5 footprint you are trying to cover, you will need to either use the appropriate amount of T-5's or use a different light.

8 bulb 4 ft

800-1000 watts of t-5
