Different Types Of Cannabis Grow Lights

For a long time, cannabis grow lights focused on flower quality and yield. However, as the industry embraces cost-friendly practices and with The Rise of Cannabis Consumption Bars, operations move towards options that prioritize energy efficiency and sustainability

Here, we go through some of the main types of grow lights, typically used in cannabis farms:

High-Intensity Discharge (HID) Lights

HID lights include High-Pressure Sodium (HPS) and Metal Halide (MH). These two have long been favored by cannabis growers as they provide ample light intensity and cover a broad spectrum. This makes them suitable for various growth stages.

MH lights produce a cooler blue light, while HPS lights emit a warmer red color. As a result of this distinction, MH lights are typically utilized during the vegetative stage of growth, while HPS lights are preferred for the flowering stage.

HID lamps typically have lower initial costs compared to advanced LED grow lights. Additionally, they are relatively simple to install, which is ideal for experimental farmers or those setting up a new facility in a time crunch.

That said, HID lights degrade over time, emitting incandescent light. This results in enhanced energy use and increased heat, which can burn the cannabis plants and severely impact their growth.

Therefore, when using HIL lights, it’s essential to consider the appropriate distance between the light source and plants.

Fluorescent Lights

For small cannabis farms, cultivators often opt for fluorescent lights. These lights are more affordable, easy to set up, and don’t need any special equipment.

Fluorescent lights are available in various wattages and color temperatures, making them a convenient option to customize the lighting setup. In addition, they don’t use an excessive amount of energy. So they’re more suited for independent or small operations.

That said, fluorescent lights have several limitations including a low UV lighting output. Due to this issue, they are best suited for growing just one or two plants at a time. Moreover, they have a shorter lifespan compared to other types of lights, which could end up causing extra costs, particularly in large commercial setups with multiple harvests.
