Now that Mr L has 'retired' he is working on setting up a hydroponic vegetable garden He has been thinking about this since we saw a hydroponic system here a few years ago
In very simple terms it is a way of growing fruit and veg without the use of soil. The plants grow in small containers, such as guttering or in trays. They dangle their little roots into nutrient rich water which is pumped round. The system can be used in a very small space.
