Choosing a Grow Light

Choosing a grow light is based on many factors such as light spectrum, energy use, and maintenance. Electromagnetic spectrum, ways to measure quantity and quality of light, as well as the equipment necessary for effective grow room illumination are also part of any decision process. Start with identifying the right grow light for your circumstances. Choose quality long lasting lights, ballasts, and bulbs. Once setup be sure to monitor your growing progress. You may need to make adjustments along the way, such as timing, to produce the best environment for your plants to thrive.

We've got some good information to help you figure it all out. So lets get started. We’ll cover everything you need to know about which grow light to buy.

Popular Types of Grow Lights

HID (High-Intensity Discharge) Lighting

The most popular form of indoor grow lighting is still the tried-and-true HID (High-Intensity Discharge) lamps. These powerful grow bulbs come in a variety of standardized sizes: 250W, 400W, 600W and 1000W and will all require a specialized ballast to operate.

The two types of HID bulbs are Metal Halide (MH) and High Pressure Sodium (HPS). Metal Halide bulbs emit a white/blue light that encourages plants to grow compact and bushy. Most growers utilize MH bulbs during the vegetative phase of the plants’ life cycle. HPS bulbs produce a yellow/red light that encourages fruit and flower formation and will be typically used during the flowering phase of the plant’s life cycle.

Fluorescent Lighting

Fluorescent lighting is another popular type of lighting common in indoor grow spaces. These energy-efficient fixtures are great at spreading light out over a large area. These types of lights are typically used for younger plants or plants that are in the vegetative phase where high-intensity lamps are not needed. Fluorescent bulbs are available in a variety of color spectrums and typically do not require an additional ballast to operate (most fluorescent fixtures come with the ballasts built-in.)

LED Lighting

LED (Light-emitting Diode) is a new type of lighting that is quickly becoming popular among indoor growers. LED lights feature extreme energy efficiency and long life, making them a cost effective way of illuminating small spaces. LED lamp manufacturers can offer these fixtures in a ton of sizes and in nearly unlimited combinations of colors.
