“LEC” and “CMH” both refer to Ceramic Metal Halide grow lights, which is a type of HID light that is a bit more efficient than a regular Metal Halide light

Some types of induction lights are well suited to stadium lighting but honestly they just aren’t that great for growing cannabis and they come with huge price tags. Even a lot of LEDs are cheaper and you’ll get better results with them. You can learn more about induction grow lights here.

High Pressure Sodium grow lights are often used during the flowering stage because they are very efficient and their yellow light stimulates bud production. HPS grow lights in the flowering stage get better yields per watt of electricity than any other type of grow light available today, which is a big part of why they are so popular.

Fluorescent grow lights come in many different shapes and sizes, from twisty bulbs to long tubes. Fluorescents are popular because they make efficient and pleasant lighting for humans, and also work great for herb gardens and other types of low-key indoor gardening without using a lot of electricity.

So, not just any light will do the job. “Yes, cannabis plants need specialized lighting solutions to support photosynthesis, and horticultural lighting products are designed to optimize plant development, unlike your office desk lamp,” according to Schimelpfenig.

Some plants, such as microgreens, may flourish under basic desk lamps, according to Zartarian. But cannabis plants need brighter and more consistent light to carry them into maturity. At the same time, cannabis plants need a so-called “dark period” during the flowering stage, but ample light is key throughout most of the marijuana plant life cycle.

To help you choose the best grow lights for your indoor cannabis garden, Weedmaps tapped into the specialized knowledge of a team of experts from the Resource Innovation Institute (RII), a non-profit devoted to efficient cannabis agriculture in Portland, Oregon.

Do I need a special light to grow plants indoors?

Bottom line: Choosing an LED grow light specifically designed for plants is a reliable way to ensure an abundant harvest.

As the cannabis plant matures, its need for light will change. “As the plant gets bigger and matures into the flowering stage of its life, it requires much more light over a wider area to grow optimally. This is where high-power, purpose-built grow lights are needed to get the job done properly,” explained Zartarian. In terms of what to look for, Schimelpfenig pointed out that growers can ‚Äútrust third-party certifying organizations to test and validate the claims made by manufacturers.”
