HOT BED
Hot beds are used in western countries for raising plants in the early seasons. It mostly provides a hot rooting environment for the crop.
It consists of three parts;
A) Frame
B) Cover and
C) Heating system
In general, the bed is made up of wood, steel, aluminum or concrete. The cover is made up off glass or plastic. Heat is provided artificially bellow the propagating medium by hot air/ steam/ hot water/ soil heating electrical cable. A thermostatically regulated electrical heating system provides a precise control of temperature. In India, the use of hot bed is quite less due to the high cost of construction, which is beyond the reach of common growers.
