I’ve had an Aerogarden for about 2 years now. When my wife and I moved into an apartment building, I really missed having my own backyard garden, and I thought that this might, in some small way, act as a replacement. I’ve been moderately satisfied with the results, and it’s fun to grow your own kitchen herbs.
As with all advertised products, the yield isn’t what the box or the literature would have you believe. Since I’ve had my system, I’ve grown two different herb mixes (the one that comes with the system, and an additional european herb mix) as well as the yellow and red cherry tomato kit. Invariably, one or more of the varieties of herb will take over and dominate the available light unless you diligently trim them back. In my most recent attempt, the savory, chives, and thyme have all suffered at the hands of the overwhelming mint, basil and parsley. As for the tomatoes, the output was pretty disappointing. I think I managed to get fewer than 50 tomatoes for my effort — though the system did have its issues, because water ended up corroding the electrical contact for the internal pump and as such, the water didn’t really circulate the way it was supposed to.
The set up is pretty simple, and you see the seedlings sprouting within a week or two, and you can start harvesting fresh herbs within a month. Maintenance is easy, too. Just add water every so often, or when the red LED lights up, and toss in a couple of fertilizer tablets (which is supposedly completely organic — seaweed somesuch) every week. The seed kits all come with fertilizer, which runs out after about 6 months, though the plants still seem fairly vigorous at that point. Presumably, you could purchase some sort of liquid fertlizer and keep the system going for longer. I’ve restarted just for the novelty of it.
