Is "turbo garden" a brand name, or a style of hydro-garden?
I'm somewhat interested in this, but I'm probably too lazy to do it. Potted herbs (herbs in pots, just to be clear....) out for the summer, and brought into our (usually) frost-free porch for winter works for us and is very little work.
A chain of local brewing supply shops is also big on hydroponics. The standing joke is that buying anything there gets you on some DEA list. I was in buying beer brewing ingredients, and I asked a bit about some of the smaller hydroponic systems. I kept saying, 'yes, I want to grow a few chives, and basil - that's all, really'.
DW got an AeroGarden as a gift. It's OK, kinda noisy (air pump), and is expensive for what you get, esp if you buy their replacement products (seed pod, fertilizer, light tube). It was 'fun', but she didn't set it up the next year, so that says something.
