Families can use various boxes or cans as containers and foam boards as floating fixtures to produce vegetables and fruits. Planting management: Move the cultivated net-rooted seedlings to the floating board for planting, add proper amount of nutrient solution into the water according to the use concentration, and debug the regular aerobic system. One oxygenation pump can supply oxygen to multiple boxes or boxes.

Leaves and vegetables can be harvested when they grow to a certain biomass. Don't wait until they are old. Because hydroponics grows fast, the quality of harvested fresh leaves and vegetables is better, and annual production can be realized.

Hydroponic vegetables:

Hydroponic vegetables refer to vegetables cultivated in traditional soil cultivation, in which most of the roots grow in layers of nutrient solution, and only the nutrient solution provides water, nutrients and oxygen. Hydroponic vegetables have a short growth cycle and are rich in vitamins and minerals necessary for human body.

Hydroponics is a kind of soilless culture, which belongs to substrate-free culture. Non-substrate cultivation means that the roots of plants grow in nutrient solution or humid air with nutrient solution, but some substrates may be used in seedling raising.

Hydroponics refers to a soilless culture method in which most roots of plants grow directly in nutrient solution layer. Mainly includes: nutrient solution mode technology, planting plants on a shallow nutrient solution layer with a thickness of 1-2cm, and continuously circulating.

Deep flow technology, the depth of nutrient solution layer is at least 4-5cm, the deepest is 8- 10cm, and sometimes even deeper, and the nutrient solution circulates according to the set frequency. Floating tray hydroponics technology, a piece of foam plastic covered with non-woven fabric is placed in a deep (5-6cm) nutrient solution layer, and the roots grow on the wet non-woven fabric.
