This website is a collection of past growing projects I have worked on over the past 6 years or so. My favorite crop is hot peppers, but the growing systems can be used for just about anything.
This picture shows the basic layout for the float-n-slope system that works very well if you have enough room in your yard to set it up.
Some lettuce ready to eat. Also note the added pipe system with some hot peppers growingin 32 oz cups. Construction info on original website
An easy to build self-watering grower suitable for tomato plants, Peppers, and many other expensive vegitables to help offset today's high food prices.
