Complete answer:
Sand culture is a hydroponic method of growing plants. To understand this first we need to know what Hydroponic is. Hydroponic is a method of growing plants or crops without soil instead mineral nutrient solutions are added in an aqueous solvent.

Soil less cultivation is a method used to grow herbs, flowers and vegetables. In this method gravel and sand bed is made instead of soil to anchor plants. This method is quite efficient and is commonly used in arid regions and dry middle east regions. It is also an economical method due to common availability of sand on earth. These beds can be reused in future.

However these beds are to be treated with nutrients due to increased salt content. This method largely decreases the botanical ailments. Due to supply of nutrients, these plants remain healthy. There is no nutrient imbalance in the soil bed.

Sand has a good capillary action which promotes the distribution of nutrients. The only drawback is that sometimes the soil less method may need additional agricultural pipes to remove excess water, minerals and nutrients.
