Soil vs. Hydroponic Tests

Do you have tests of your experiments when you compared hydroponics to normal soil growth?

Lettuce growers in soil produce 3-5 crops per year, and in Hydroponics they produce around 10-14 crops a year.

Tomato Growers in Soil get about 3 trusses of fruit in the same time the hydroponic grower has 5-7 trusses.

These come from farmers and general knowledge about crops.

If you want tests, go to the ABC of NFT and read Dr Coopers work, right down to sugar content in fruit and stuff like that.
