Definition - What does Sand mean?

In hydroponics, or soilless growing, sand is often used as a medium for different types of plants. Not unlike gravel culture, sand culture is especially used in the Middle East because of the dry and arid climate. More importantly, using sand as a growth medium has been shown to yield excellent results with different types of plants.

Another advantage of using sand as a growth medium is that it's extremely budget-friendly. Indeed, sand can continuously be re-used, unlike other types of growth mediums. Because sand is abundant in just about every country, it also has the advantage of being relatively inexpensive. However, it's important to note that sand has to be treated before use because its high salt content can be detrimental to plant development and growth. Additionally, because sand is efficient against common plant ailments such as fusarium and verticilium, it's considered as an efficient method of hydroponics.

Sand has also been shown to be easy to maintain, especially when compared to other types of hydroponics. When working with sand on a large-scale basis, it's important to install agricultural pipes that will channel away excess nutrients, water and minerals.
