Best Cannabis Grow Lights for 2020

Today, there is a broad spectrum of grow lights on the market, and you have a lot to consider when deciding the best source. The size of your grow space, the positioning of your plants, and the distance between your canopy and the plants are all factors that can impact which lighting system you should use. Read on as Lift and Grow breaks down three of the more common options of cannabis grow lights!

Best Indoor Grow Lights for Cannabis in 2020

Healthy and mature plants depend on an adequate lighting system. Increase the ROI of your cannabis grow room by choosing the right light source.

1. HID Lights

High-intensity discharge (HID) lights are ubiquitous for growing cannabis plants. Under this category are two types of grow lights: metal halide (MH) and high-pressure sodium (HPS) lights, both of which we outline below. As a whole, HID lights are cost-effective to set up, long-lasting, and are known to produce excellent results. Many cannabis growers choose to begin with MH lights and move to HPS once the plant reaches the flowering stage.

  • Metal Halide (MH) Lights
    MH lights pass an arching electric current through a mixture of gases, which produces an ideal light spectrum for cannabis plants. They’re best utilized during the vegetative stage in which stems, branches, and leaves need to reach photosynthesis. Their high power mimics that of outdoor lighting in the fall and spring and is thought to induce the flowering stage.
  • High-Pressure Sodium (HPS) Lights
    HPS lights also pass an electric wave through a bulb but are mainly composed of sodium. Their dull red-orange glow is an ideal light source for cannabis plants in the flowering stage. When used in this phase, or as a secondary light in the growth stage, HPS lights activate plant hormones allowing for higher production.

2. Fluorescent Lights

Fluorescent grows lights are a less popular alternative in cannabis cultivation because they can require multiple types of light bulbs to be effective. But their lower light output can be helpful in later plant growth stages. We recommend this light system for small spaces where plants are kept short. Cannabis growers can train their plants to grow short, which is great if space is a concern. When shopping for compact fluorescent lights, consider the T5 bulbs, which have a heavier light output. These light bulbs are more effective in growing smaller plants through to the vegetative stage.

3. LED Grow Lights

Light emitting diodes – or LED lights – have taken the lighting world by storm in the past decade. What was initially thought to have spotty coverage (and be very expensive!) is now a common choice for indoor cannabis and other plants due to recent improvements. Today’s LED systems can evenly disburse lights across a grow room, avoiding any dead zones across your canopy. They’re an energy-efficient solution, so although they may cost more initially, their low voltage helps keep electricity bills down overtime.

Each light source offers different advantages. When deciding which cannabis grow lights to purchase, be sure to research the effect it will have on your indoor operations!
