grow lights for weed at home depot

For growers who are looking to harvest 1/2 to 1 ounce of cannabis a month, LEDs may be your best choice. At this size, they are super low on electricity, run cool and need almost no setup! They get better yields than fluorescents but don’t run as hot as an HPS of similar wattage.

Ceramic Metal Halide (CMH) & Light Emitting Ceramic (LEC) Grow Lights.

For the many growers who are unable to cultivate cannabis outside in the free abundant sunshine, grow lights are necessary to successfully grow cannabis indoors. Grow lights take the place of the sun, and power the growth of your plants and their buds. Light is like “food” for your plants, so without a lot of bright light, even a healthy cannabis plant won’t produce much bud at all.

If you get very high-wattage LEDs, you may need to vent out heat to keep the grow space cool.

Cons of Fluorescents.

Note: When shopping for LEDs, make sure they contain some amount of green or white (full spectrum) light. Plants grown without at least a tiny amount of green or white light are very prone to nutrient deficiencies and simply don’t grow as well.

3 Main Classes of Marijuana Grow Lights.

That being said, when it comes to the flowering/budding stage, if you can fit a bigger light you will get significantly better yields/watt by using an HID or LED grow light!

T5s are much bigger/wider than CFLs and usually come as part of a panel, but they can still be kept mere inches away from your plants without worrying about burning them.

Pros and Cons of HID Grow Lights.

Keeping CFLs close results in the best yields and growth.

Pros of Fluorescents.

The light from a Metal Halide appears a little bluish, and is well suited to growing cannabis plants in the vegetative stage.

LED grow lights are very popular among cannabis growers as an alternative to HPS grow lights. They tend to run cooler and also usually come with built-in cooling. They can often be plugged into a wall and simply hung over plants which is definitely easier than setting up an HID grow light. LEDs also have great penetration so they don’t need to be moved frequently like fluorescents.

The light from an HPS appears yellow, and is great for flowering plants because the light spectrum stimulates bud production.

3.) LED Grow Lights.

These are actually just two names for the same thing. This type of metal halide bulb uses ceramic as part of the lamp just like an HPS. As a result, CMH bulbs are more efficient than regular MH lights (though still not as efficient as HPS bulbs).

2.) High Intensity Discharge (HID) Grow Lights.

HID grow lights are much more efficient than fluorescent lights and are powered by large, oddly-shaped bulbs. They are usually screwed into a reflector or hood to reflect more light down onto the plants. HIDs are great at growing cannabis, but they also get very hot and are usually hooked up to an exhaust to help vent out heat.

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.

Note 2 : Incandescent light bulbs (old fashioned light bulbs) are NOT suitable for growing marijuana!

Example of MH/HPS Setups That Yield 1-5 Ounces/Month.

These cannabis plants are thriving under T5 grow lights.

Metal Halide grow lights are generally used for the vegetative stage because they produce a bluish light that vegetative plants love, though this type of light can also be used all the way to harvest.

There is a larger size MH/HPS grow light available (1000W), but at that size it starts going outside the scope of a “hobbyist” grower as far as ease and yields. In addition to needing a lot of extra cooling which costs electricity, a 1000W HPS grow light is less efficient compared to a 600W grow light (as far as how much light is put out for electricity used). I think most hobbyist growers would be happier with a 600W, or even two 600W lights, over a 1000W 🙂

T5 grow lights are one of the most easily available types of grow lights and are used to grow many different types of plants. As a result, they’re available in many garden and home improvement stores.

Full tutorial on CMH / LEC grow lights (LEC stands for “Light Emitting Ceramic” and is a type of Metal Halide bulb that is built with ceramic like an HPS – basically it’s sort of like a blend between MH and HPS bulbs)

“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.

High Pressure Sodium (HPS) Grow Lights.

I've seen LED grow lights at home depots here in Canada, thought it was odd to find them there while looking for lights for the house. This was also easily over a year ago. I know people grow veg indoors and everything , but still.

Full grow kits to follow. And just maybe some day, far in the future, we'll find some small "Blue-Dream" in the garden section- on sale! (Customer needs assistance for a large purchase!!)

I should move to Washington and get started on this.

I'm surprised they aren't already being manufactured. A cheap kit for one or two plants and a guide with tips and photos would go over great. You could even leave room for them to expand on their grow.

But then Wells Fargo will stop doing business with Home Depot.

be careful frients. Alot of these 'blurple' lights are garbage. I don't blame HD for wanting to cash in. Just make sure you do your research first before buying any of these blue/red style led panels. IME they will grow plants, but are junk when compared to highend leds such as cobs. The tech has advanced so fast that the new high end LEDS are comparable in price to these old style of 'blurple' led panels.

Assuming a standard amount of usage, quality LED grow lights should last for at least 10 years. Many products come with warranty coverage around this length of time.

Plants need a different amount of light during different stages of the growth cycle. You can control the intensity by changing the height of LEDs above plants.

12 to 18 inches.

24 to 30 inches.

18 to 24 inches.

Q. How long does LED grow lights last?

Q. What are double chip LED grow lights?

Double chip grows lights are equipped with two semiconductor chips per LED instead of one. This means they’re twice as bright as a normal LED. They’re excellent for large growing spaces, as you get a more powerful unit without it being huge and unwieldy. If you have a small canopy, you don’t need double chip LED grow lights.
