Balcony vegetable garden planting method without soil

Soilless cultivation is actually very simple, go to the flower market and buy some peat soil and perlite, and mix it in a 7:3 volume ratio. You can plant it on the balcony in a container or brick trough, and you can buy the nutrient solution from the large flower market.

In fact, it is not a nutrient solution, just buy imported water-soluble compound fertilizer, these fertilizers in addition to a large number of elements nitrogen, phosphorus and potassium other trace elements are also available, with this fertilizer to water plant growth is no problem at all, but in the different growth period of the plant to use different proportions of fertilizer. High nitrogen fertilizer at the seedling stage, high potassium fertilizer at the middle stage, and high phosphorus fertilizer at the flowering and fruiting stage, these fertilizers have finished product formulas, which can be bought, and they can be watered at home by 1000 times with water.

Soilless cultivation is a modern seedling raising technology that uses light materials such as grass peat, forest humus, vermiculite and other materials as seedling substrate to fix plants, so that plant roots can directly contact the nutrient solution, and adopt mechanized precision sowing to become seedlings at one time. The selection of seedling tray is divided into compartments, sowing a grid and a grain, seedlings into a room and a plant, the root system and substrate of the seedlings are intertwined with each other, and the root mounds are in the shape of a large and small stopper, which is generally called the soilless seedling of the hole plate.
