I used to have a C-99 that smelled exactly like pink grapefruit. I'd look into the fruity smelling strains. Then there are the little fan type air fresheners- I don't like them, but they work. I run a "stealth" cabinet for my clones and seedlings and a closet for 12/12, so I always have plants at all stages.

If you are still worried about power consumption, just go through your house and replace all the conventional light bulbs with CFLs! It adds up pretty fast! I even grow with CFLs and get reasonable harvests. My closet only uses about 400 watts, but it is BRIGHT in there!- Granny:hippy:
