im looking to start growing some vegetables at home, but i live in the city with no grass in sight, so i want to invest in one of those indoor gardening contraptions, but i dont know a thing about them or what to look for. does anyone have experiences with a particular brand they liked or disliked? and what kinds of vegetables would i be able to grow? thanks in advance! :)

You could look up the information here: http://www.cropking.com/hobby and here: http://www.growingedge.com/basics/start.html.

Start small and do not be afraid of making "mistakes".

Good health and a lot of wealth!
