Question

it is called hydroponics when you grow a plant in water.

Answer 1

Agriculture-Actually, sand is a type of soil. Soils are composed of three particle sizes: sand (0.05 to 2.0 mm diameter), silt (0.002 to 0.05 mm) and clay (less than 0.002 mm).
Sandy soils can grow excellent plants if adequate water and fertilizer are supplied. Grass growing in pure sand is popular for golf putting greens and football fields in pro and college stadiums because sand does not compact like loams, drains well even during heavy rain, and doesn't muddy uniforms.
Plant cuttings can be propagated in pure sand or sand with peat. But contrary to popular belief, Cacti don't grow well in plain sand.

Soils are named based on the percent by weight of sand, silt and clay they contain using a soil textural triangle.
