lights used for growing weed

You can find HID reflector hoods, as well as MH and HPS bulbs at any local grow shop.

LEDs (light emitting diodes) are relatively new to the cannabis growing world, compared to HPSs, MHs, and CFLs, but they are quickly proving to be the way of the future. LEDs may be more expensive to buy initially, but they are far more efficient and kinder to the environment and your electricity bill. Some cities even give tax breaks to commercial growers who install or switch to LEDs because they’re better for the environment.

Make sure you have enough outlets and power available in your breaker board for your grow space to comfortably accommodate all equipment. Figure out all pieces of equipment, such as lights, fans, possibly an AC or dehumidifier, and calculate how much power they’ll require. You’ll be running this equipment every day for months, so if you don’t have enough power it can be dangerous. Never overload an electrical outlet.

HID lights for growing marijuana

For HIDs, light occurs as an arc between two nodes inside the bulb. The gas contained in these bulbs is what makes MHs and HPSs different. HID bulbs are usually more expensive than the reflective hoods that hold them.

New LED grow lights come out all the time, but knockoffs abound. There are a lot of cheap LEDs that don’t produce the right spectrum of light for plants.

CFL lights for growing weed

However, because of their low price, if you’re new to indoor growing and not sure how often you’ll do it, you may want to invest in an inexpensive HID light at first to test the water.

CFLs (compact fluorescent lamps) are fluorescent lights similar to what you’d find in a school or office building, but smaller. For growing weed, they are usually called “T5s”—the “T” stands for “tubular” and the “5” refers to its diameter, “⅝”.

Lights used for growing weed

● They are the most intense light option available, ensuring your plants get all the light they need.

● They can require large boards of LEDs due to their relatively low power.

Growth Cycle Stage

Fluorescent lights also don’t require a ridiculous variety of different lights like HID lights.

● HID lights require additional investment in protective hoods and reflectors.

Safety

● Low electricity usage.
