Theory of operation

This is a simple hydroponic garden that allows your plants to grow directly in the nutrient solution by providing physical support with GroRox and oxygenation to the roots with a common aquarium air pump and air curtain.

The diagram at right details how the roots grow down through the GroRox into the nutrient solution which is aerated by the release of bubbles from the slowly leaking supply line (aquarium air curtain).

To get started building this garden, you'll need only the most basic parts which you shouldn't have trouble finding locally in stores that sell garden and pet products. If you run into problems sourcing the parts, visit the FutureGarden store online at
