In theory, it can. Generally, plants can survive as long as they meet the requirements of light, water and nutrition. There is a problem here, sand is just a simple particle, does not contain any nutrients, can you support plants?
Generally, this kind of culture uses sand as the substrate, which does not contain any soil substrate to cultivate plants, which is called soilless culture. In this way, water and sand without bacteria are used instead of soil as the growth matrix of plants. Mix in inorganic fertilizer as plant nutrient.
In this way, diseases and insect pests caused by soil pollution can be effectively avoided; the inorganic fertilizer added inside has no taste, will not breed mosquitoes, and is very clean and sanitary. In this way, the color of the leaves is more green, and the flowers are many and big, the color is also very beautiful, and the flowering period is very long.
(1) suitable utensils are needed for soilless planting. Generally, a round glass tank for goldfish is used, and then a layer of opaque black paper or black cloth is wrapped on the outside of the tank, and finally a layer of white paper is wrapped. This is a way to keep the darkness, not only to avoid the propagation of algae in the light of nutrient liquid, but also to prevent the underground stems of plants from turning green, affecting the blooming of flowers. If you don't want to be so troublesome, you can buy porcelain basin or purple sand basin directly.
(2) the type of sand can be coarse sand, which is mainly used to fix the position of lotus root. When planting, first place the lotus root across the surface of the sand, and then put some sand on it to cover the whole lotus root. It is worth noting that the tail of lotus root must be raised. Finally, slowly pour water into the basin.
(3) because the lotus root itself has nutrition, it will sprout its own seedlings and grow out of the stem, and then grow out of the leaves.
(4) however, as the nutrition of lotus root will be consumed sooner or later, we should add some nutrient solution containing rich elements once a week.
