Garden/Hydroponics Veggie Garden

What

I would like to build a vertical hydroponics veggie garden.

It works by pumping water and nutrients to the top of the garden and gravity feed all the plants on the way down. As the water is constantly on the move it doesn't become stagnant and the nutrients/healthy bacteria mix helps keep the system free of clogging and pests.

Requires a water and nutrients top up once a week.

In an ideal world we would also have a yard webcam to make it easier to keep an eye on the health of the system.

Pros

• cost approx £200
• build can be done in a weekend
• no soil or compost required
• uses 80% less water than conventional soil-based veggie gardens
• takes up less space than a garden bed
• plants "hypergrow"
• low maintenance - prune and water/nutrient top up once a week
• flexible - the frame can be constructed on wheels so it can be moved around, plants can be rearranged
