A PVC hydroponic garden

www.learninghydro.org Hydroponic rocks make a PVC pipe into a self-contained hydroponic garden. A drain pipe can be converted into a hydroponic garden for a balcony, walkway, or fence. Fill the large diameter pipe with hydroponic rocks, then water with a drip system or pumped flow. Chipped brick or rock wool can also be used. The interior of the pipe creates a closed space for roots. The upper curve of the pipe protects the roots from light and air. The length of a single pipe can be twenty feet. A scrap drain pipe can reduce the cost of the project to less than 0 including the pump. Go to the website http for the hydroponic components, the local plumbing shop for the PVC and fittings.
