Hydroponics – Small Scale
I recently visited EPCOT in Orlando and was impressed by the tour of their hydroponic system for growing vegetables.
If you want to experiment with this system of gardening without soil, here are some valuable resources:
Alabama: Hydroponics for Home Gardeners (includes directions for mixing your own nutrients)
Source for nutrient chemicals (They ship only to a business and accept only business credit cards, so I used a friend’s business information with his permission.)
