|Four tower hydroponic system from Vertigro|
This type of gardening system is often used in areas with poor soil quality due to environmental factors such as hot and arid climates with sandy soils. The basic system provides a commercial quality food production system option for backyard gardeners without the time, effort, and expense involved with building above ground growing beds.
If I understand the price lists correctly, this system is sold for approximately $400. That may sound like a lot, but if you price supplies to build a traditional above ground bed separately you might be surprised to find that $400 isn't quite as high as it might first seem. Counting the water savings alone versus traditional sprinkler and drip irrigation, the break even point might surprise you. Plus you don't have to worry about weeds, cultivation, bending, stretching, etc. to harvest your food.
For comparison purposes, here's a picture of the main hydroponic system used by the CSA to provide weekly vegetable supply for CSA members and a couple of local produce stands.
