I was running a 24" new wave t5 in a 5x6x6 room as the only light, and using that room only for propagation- it was EXACTLY the correct amount of light in that space. But if you want only a single light, go for the MH. It will actually save electricity in the end.
Thanks again for the fast reply Miss Stinky Attic!

Can you tell me more about the MH light, mathmatically I'm not comprehending how the MH light is better on electricity. The room will have 2 mothers, 12 clones rooting, and 12 vegging most of the time. The room is 6 feet wide by 5 feet deep and has an 8 foot ceiling. Using a charcoal filter and inline fan in that room as well.

Thanks!!
