River sand suitable plants

River sand is a mineral that is insoluble in water and contains very few nutrients needed for plant growth. Generally speaking, river sand is not used for its nutrients when growing plants, but, like vermiculite, it serves as a support for the plant roots in soilless cultivation. When carrying out soilless cultivation, nutrient solution should be applied to supplement the nutrients needed for plant growth. When cultivating malt, sterilized river sand can be used for cultivation, and river sand can also be used as a mixed matrix to grow succulents.
