If you really want something that really works, then the Klimagro is the "bomb"!www.klimagro.com
I've got the Majestic, which is 4' tall and the Classic which sits in my "garden window" over the sink in my kitchen.
Right now, I've got everything from cactus, basil, oregano, aloe, and a tomato plant growing in the Majestic. Soon, I will be growing starters for the outdoor garden in it.
The Classic has a huge Rosemary bush growing in it, and it is the most pungent great tasting fresh Rosemary I've ever had. I've grown 5 types of basil simultaneously in the Classic, as well as oregano, thyme, marjoram, and even decorative plants.
They have little fans for air ciculation, sliding auto safety glass doors, built-in heater and temperature selector, built-in humidity wand and gage, built-in lights and timer (set for 18 hours so plants don't flower, or at 12 hours to flower).
They're built rugged, and are easy to keep watered (by using the retractable faucet hose on the sink).
