Dear Sir, I am in grade 8 and I have always been interested in growing of vegetables etc. I am doing a energy saving experiment at school and I have selected hydroponics. I need to build a simple experiment that shows the energy saved. Can you suggest a basic idea that will appeal to students and parents. Regards Lindsay Scott
The Advantages of Hydroponics include Less weeding, bending, digging, machinery used. Less use of tractors and polluting farm machinery. More efficient use of water resulting in 80 litres per 1kilo of produce produced in soil and 3 litres of water used per 1 kilo in Hydroponics. Energy saved is fairly difficult to identify. Physical energy is reduced compared with normal gardening. Would something along those lines be suitable?
