Nothing wrong with CFL's, they are pefect for small scale growing in restricted spaces.
I'm not a big smoker either, half OZ does me a month easily! I grow in a metre square cabinet thats just deep enough to take my 10" pots and I yield a good solid OZ per month average, more than I need actually, but I can shut down a couple of times per year
An alternative to tents is to buy a cheap second hand wooden chest/cabinet and convert it? Not much DIY involved and they are much less obvious than tents. I also find its easier to work with wood, more solid for hanging fixtures etc. Just my opinion.
A couple of small plants under CFL's would more than cater for your modest needs, and don't let anyone tell you that you cant grow nice buds with CFL's .
(Below) Nirvana Northern Lights, 350watts CFL's, 2 10" pots grown in a metre square cab, 1 intake, 1 exhaust fan plus a small circulation fan, temps at 78 max, averaging 75.
Hope this info helps in some way?
