What is a ballast?

Ballasts have become an essential part in indoor marijuana growing; this device regulates the current, keeps stable and limits the electrical intensity of the lamps used in the space destined for indoor plantations.

More specifically, ballasts are usually used with either HID (high-pressure discharge) lighting systems, with high-pressure sodium (HPS) or metal halide (MH) lamps, which should not be connected directly to the socket. In addition, the LEC lights need a specific ballast.

The ballast supplies power to the lamp by means of voltage regulation, preventing the HID lights from receiving too much current at once. This device, also known as a ballast, ensures the correct current is supplied at all times. There are other types of lights on the market, which have a built-in ballast.


It is very important to make sure that the electrical power of the ballast matches the power required by the lamp, and only connect one bulb per ballast.

It is also advisable to keep the ballasts out of the growing space and away from the ground, so that the risk of damage from splashing and high humidity is minimized a little. Handle and take care of this equipment so that no harmful accidents will occur.

For your part, make sure you choose the type of ballast (magnetic or electronic/digital) that is ideal for your growing and type of lamp.
