can u grow weed with led lights

Another thing to consider is how much money LED cannabis grow lights will save you on your energy bill. HID lights are good at what they do, but the amount of energy they use will cause your energy bills to skyrocket. This not only hurts your pocketbook, but it can also draw unwanted attention in your direction either by a landlord, a nosy neighbor, and/or the police. When people had to keep their marijuana growing activities under wraps, spiking electricity bills often gave them away. While cannabis is legal in more areas now, this does not necessarily mean that you want the whole neighborhood knowing what you are up to.

There are many reasons to use LED lights when growing cannabis.

Affordability

Not only are LED lights more energy-efficient , but you’ll also save on water usage as well. As you are now aware, HID lights use a lot of energy, which in turn produces more heat. This dramatically increases the temperature of the grow room, causing your plants to consume more water. Cannabis is already quite the water hog when compared to other plants and growing even just a small amount of plants uses a lot of water. Any way to reduce water consumption is great for the environment, not to mention great for your utility bill.

With LEDs, you don’t have to place your plants as far away as you would with HIDs. Keep lights below 300 watts about 30-70cm away, or just around 12-27 inches. Lights above 300 watts should be kept at 70-80cm away, while gradually decreasing space when flowering. Larger wattage like 450 should be close to 80 cm or 31 inches.

Different Types of Cannabis Grow Lights

The benefits of using LED cannabis grow lights are many. The next big question is how to grow marijuana using only LED lights. A good rule of thumb is one light per every 1.5 square feet. This generally will yield you up to 6 ounces per plant, which ends up covering what you spend on the light and will definitely end up saving you money in the long run. If you are growing only 1-2 plants, our single 75 watts LED light supplies plenty of light for your plants.

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

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.

Some grow lights are more expensive than others, but also more efficient, saving money in the long run. Some lights are bulky with many parts, some light in weight, and some are better suited for young or mature plants.

HID lights for growing marijuana

HIDs have been the standard in indoor weed growing for decades, but LEDs are quickly catching up to them.

Here are a few different HID grow lights at different price points.

Ventilation

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.

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.

My search for LEDs started because I live in an area where heat can be an issue. I am also a small scale grower who would like to still have a presentable house for guests.

Pros Will outproduce a 400W HPS using only 240 watts of electricity, very little heat produced, and buds are "Potent enough to catch even experienced patients off guard, to the point that the batches out in the local Med community have been nicknamed 'Warning Label.'"

Plus I was saving money on my electricity bill (electricity use with the Lighthouse Hydro Blackstar LED Grow Light was minimal), and there was no heat to speak of, which really simplified the heat situation in my tiny, tiny closet.

Based on the experiences of some of my fellow growers, I discovered many LED grow light systems just don't work for growing marijuana.

Some people say LEDs work great for growing marijuana, while others claim LED grow lights are junk and can't be used to grow anything.
