Marijuana Grow Light Types
Before we get into the specific brands and models of grow lights, let's consider the different light types available. Each light has its own pros and cons. Some may offer a lot of lighting power for big gardens while others may provide just enough light to get you started on your first garden.
You can find many marijuana grow lights on Amazon or purchase them directly from the manufacturer. You can find tons of cheap grow lights for cannabis and more expensive ones with better technology and lighting efficiency.
- LED Grow Lights: Light-emitting diode (LED) lights generate considerably less energy than other light sources. However, its energy-saving capabilities can be expensive for some budget growers. If you have the budget to splurge a bit, LED lights don't produce as much heat as other lights, thereby, avoiding overheating your garden. If you want a light with a long life-span, go with LED.
- HID Grow Lights: Hi-intensity discharge (HID) lights produce a considerable amount of lighting power compared to LEDs or fluorescent bulbs. Mainly used in large commercial grows, the intense light and heat from these bulbs require a full exhaust fan to keep temperatures stable. HID grow lights come in several varieties, each with a different color spectrum to cater to a specific stage of the growing process. Go with metal halide bulbs (MH) for the vegetative state or high-pressure sodium (HPS) for the flowering stage.
- Fluorescent Grow Lights: Most home growers will start off with the traditional fluorescent lights: the T5s or the CFLs. Fluorescent bulbs don't use a lot of electricity and tend to produce a low heat output, which may require you to place them close to your plants. Choose lights with cool, warm, or full-spectrum colors, depending on your stage of the growing process.
