High-Pressure Sodium Lights (HPS):
Halogen lights create a lot of very intense light. They are often used for lighting large areas. Unfortunately they create a vast amount of heat that makes them completely unsuitable for a growroom setting as they pose a real safety hazard, as well as easily overheating your plants.
There are various types of grow lights on the market available to cannabis cultivators. It is important to choose a grow light that suites your needs and fits within your budget.
As you’ll see below, that is why I generally recommend CMH or LED over MH or HPS. You don’t need to combine two different lights to get a great spectrum for every stage.
