Light bulbs for growing weed indoors

There are plants like microgreens that can flourish with a basic lamp. However, marijuana plants require fairly strong and consistent light to help them into the blooming phase. Remember, when you grow cannabis indoors, you’re competing with the sun in terms of light! This means you need high-power lights in your plants’ grow space.

Why Should I Use Indoor Marijuana Grow Lights?

Short for light-emitting diode, an LED is a simple form of light with an efficient energy signature. Due to how the light is generated within an LED, they use a meager amount of electricity for the same amount of light compared to other sources.

High-Pressure Sodium Grow Lights

HID grow lights, short for High-Intensity Discharge, are large light bulbs that emit a tremendous amount of heat and light. They usually require a full exhaust fan to remove the excess heat, and electricity consumption is enormous. Also, they generally need a decent amount of time and space to set up a properly working system.

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.

Aside from the price of the actual light, also take into account utilities—all lights will add to your electricity bill every month, but some more than others. High-intensity discharge lights—known as “HIDs”—may be cheaper to buy but can gobble up electricity, whereas LEDs are more efficient and kinder on your electricity bill but usually more expensive to buy.

Plant stage

The downside to CFLs is they aren’t great for flowering plants, and growers will usually use another type of light to finish plants. CFLs just don’t generate enough intense light for plants to pack on weight.

How big a light you need will depend on the number of plants you plan on growing, but also on the size of your space. If you’re growing in a closet or a small grow tent, you’ll only be able to fit one small light in there. If you have a wide open basement, you could invest in a bigger light as opposed to two smaller ones.

How many grow lights do I need to grow weed?

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.
