I always wanted a cute little herb garden. There are two problems: I live in an apartment with no yard, and I have a black thumb. I generally forget about my houseplants, and then they die.
I set up two different pots, one using an air pump and airstone, the other using a water pump and some tubing/sprayers. The results have been mixed, and I’m still revising things. But now I have some basil that’s just about ready for me to steal some of. The nice thing about this setup is that it’s totally automatic. I can forget about it for a week and that’s just fine. All I have to do is top off the water once a week or so.
A full report, including an explanation of how the two setups were built can be found here: http://www.kellbot.com/category/projects/diy-aeroponics/
