I purchased an aerogarden a few weeks ago and so far so good. Will enclose a pic of 5 weeks. One of the things you can do is, to get a longer plug cord so as to raise the hood of the ag and thereby create a taller workspace.
As to the Aerogarden, its also a good thing to empty and rinse the reservoir every month as the water become toxic to the plants...I grew 24/7 for 6 weeks and then lights were only on 12 hours a day for 10 days...looks like we are just now starting to bud...will let you know what happens .
