If you want to take your first steps into the wonderful world of indoor garden lighting, a Compact Fluorescent light (CFL) is a great first step. Beginners and experts alike love these lights for their efficiency, ease of set-up and use. They can take 125 and 200 watt lamps and are available in different color outputs ('cool blue' for vegetative growth and 'warm red' for flowering and fruiting.)
This unit has a built-in ballast so it's really just a case of hanging the light, plugging in, and growing! CFLs need to be positioned fairly close to plants at a distance of just a few inches to drive optimum growth and bloom.
