can you grow good weed with led lights

Our complete grow kits include everything you need to go from seed to your very own supply of high grade medical cannabis.

What are the top lights to grow weed indoor?

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.

Those who could not afford a good set of HID lights would resort to CFLs, which, while not as effective during the flowering phase , managed to get the job done most of the time. Often times, these were the only options for growers with smaller operations, or those growing a couple plants for personal use. CFLs have gained some popularity over the years, but they would never be as popular as HID lights, which are trusted by growers all over the world. That is until LED lights entered the picture.

It used to be that lighting was one of the most expensive aspects of growing marijuana. A good set of HID or CFS lights could set you back a couple hundred with all the required equipment. Now, thanks to LED lights , cannabis grow lights are much more affordable, making growing cannabis at home much more attainable.

Even if you’d like to grow more than a few plants, you don’t have to go for the more expensive HID lights. Simply add to your setup with either a few larger LED bulbs or several of the smaller ones. If you opt to go for the latter option, make sure that your plants and your lights are spaced out correctly, as you want to make sure that each plant gets adequate amounts of light. Using too few lights can cause stretching, whereas using too many lights leaves you at the risk of light burn, as well as energy overconsumption.

Grow with the Sun.

Be careful when making any changes to your light setup. Decreasing the space between plant and light too quickly might have detrimental effects. Keep an eye on your plants and take it slow!

Getting Your Grow Lights.

Harvest up to a pound.

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

Seed Coupon Included.

You should also be aware that while LEDs don’t put out as much energy, your plants are still susceptible to light burn. So, like any other lights, make sure that you are keeping your lights a proper distance from your plants.

Reduced Water Usage.

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.

For many, the main reason is that they are relatively inexpensive when compared to the much pricier HID setup. This is especially true if you are growing a smaller number of plants. Our grow lights at A Pot for Pot are specifically designed for growing a small number of marijuana plants and is priced well under $200 – proof that high-quality lighting doesn’t need to be expensive.

If you’re a more impatient person, LEDs might not be for you. However, most beginners will benefit from using LED cannabis grow lights. In fact, they might be just the thing you’re looking for! Our LED grow lights can be purchased individually alongside our Complete Grow Kit . A Pot for Pot 75 Watt LED lights are each perfect for a pot with 1.5 sq ft of canopy, and multiple lights can be arranged for a larger grow.

This was not always the case. When LEDs were first gaining momentum among growers, the technology was still fairly new and had not entirely been perfected. Think about how expensive and inconvenient cutting-edge technology like smartphones were when they first came out, and it often wasn’t worth it. For example, many agree that the first-generation iPhone was not the greatest. However, today’s smartphones are much more affordable, and they are everywhere.

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.

Suggested Strains that have worked beautifully with the Pro-Grow 400 (with pics to prove it… click for closeups!)

But through trial and error, we've now developed some wickedly effective LED grow lights.

Blackberry: Quickly gains mass, trichomes & aromas! Fast growing, dense colas from top to bottom, trichome coated & smelling of ripe fruit and jet fuel.

First invented in 1927, no one could find any practical use for these tiny lights until 1962, when LEDs first hit the scene in 1962 as glowing red indicators on electronics.

I was pretty satisfied with the results.

After that, LED development has proceeded rapidly.

"I try to show the average guy or gal how they can free themselves from the grips of dealers and dispensaries. Hopefully this will empower other patients to do the same, and that makes it all worth it."

The truth is that both sides are right .

The Pro-Grow 400 easily covers a 4' x 4' area, and up to 5' x 5' with a little plant rotation & shuffling.

Please note: This article was written in April 2012. Since then, LED grow lights have been improved to produce even better results when growing marijuana.

The following information and pictures are here thanks to endive from Definitely check out his website out for tons more pictures and to get updates about their current and future medical marijuana grows !

As you probably know, humans have tried growing plants with just about every type of artificial light we've ever created, and LEDs are no exception.

Verdict: Great for the discrete small to mid-sized grows (4-6 plants) in a closet or grow tent. "This is a solid LED grow light that will give a 600 watt high pressure sodium system a fair run… but at half the power consumption."

My yields under the Lighthouse Hydro Blackstar were a bit smaller than normal and throughout the grow my plant leaves appeared a bit beat up (got occasional spots, brown marks, and other signs of light stress, especially the leaves close to the LEDS), but the buds produced with the Lighthouse Hydro Blackstar were always dank, ultra-poten and sticky .

Here are some pictures of the plants which were grown primarily under the Hydro Blackstar panel. The top three show the plants a month before harvest, and the bottom two photos are from the day of the harvest. The purple pictures show what the buds look like under the LED lights. Click on any of the thumbnails to see a bigger version!

Keep Pro-Grow about 20" above plants. The days of having to keep your LED grow lights just inches above your plants are over.

Price: $550 (for one of these efficient monsters)

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.

Jock Horror: Jock Horror produces so much resin that even its branches glisten with THC glands. This marijuana strain's variety has a unique fresh flavour and packs a strong "up" buzz. Buds look dank! While manicuring the freshly cut colas, I found myself having to change out or clean my scissors & shears every few branches. They are the stickiest Jock I've grown to date yet and by far the most delicious smelling, almost a melding of skunk & cotton candy!

After doing some research, I got my Lighthouse Hydro BlackStar 135 Watt LED grow light in 2012. I got a second one a few months later, I've grown 3 crops in total under just these BlackStar panels, growing two small plants under each UFO LED Grow Light panel.

Northern Lights: Quick to flower, high producing. Aromas vary from 'incense & hashish' to 'honey & tangerine', but they were all sweet & herbal on the inhale, gentle on the lungs as the spicy/incense undertones become more prevalent. You'd wish you could hold it in forever, as you reluctantly exhale, you are rewarded with one last aromatic blast of sandalwood and hashish…

Cons : Expensive initial investment.

I know this is true because I have personally have grown marijuana plants from seed to harvest with a Lighthouse Hydro BlackStar 135 Watt LED grow light system.

Where I was living at the time, I didn't want to have install ducting for ventilation or anything like that, which made HID lights pretty much out of the question for me.

In today's article, it is my goal to share with you 2 brands of LED Grow Light that have been proven to work great for growing marijuana , so you can skip the trial and error.

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.

Nirvana Aurora Indica: An F1 hybrid of Afghan and Northern Light. Its plants stay short, producing heavy colas and dense buds. This marijuana strain produces exceptional amounts of resin, resulting in a deep, near-black hash with a tasty aroma and a heavy buzz. This probably is Nirvana's most potent Indica seeds strain.

Cons : Smaller-than-average yields, someone airy buds, leaves closer than 15" to the light can show signs of light stress.

Now, it's a proven fact that LEDs can be used to grow plants from the beginning to the end of their life cycle.

LEDs are more efficient than HPS bulbs generally, and as Yorio pointed out: “With HPS, light comes out of 360 degrees from the lamp. Half the light is going in the wrong direction, to the reflector hood, and that decreases efficiency. With LEDs, all the light is going the direction you want it to.” What’s more, you can also engineer LEDs to produce only the kinds of wavelengths that plants need for photosynthesis. Boom, no more “spending money buying watts from the electric company to create light that the plants don’t use,” Yorio said.

Heavens, it’s a big week for pot questions. Why just the other day I answered a query about whether it’s safe to use plastic soil beads in potted plants, and now this. Thanks for keeping the theme alive.

Marijuana aficionados stereotypically feel a deep and abiding connection with the natural world, or so I hear. So stereotypically, I’d expect it would harsh their mell to know what a whopping energy footprint their buds have. Pot may look like an oh-so-natural herb, but until recently the illegal nature of it has meant not much grew outdoors, kissed by sunlight and light breezes. Instead, as you note, most crops have been raised indoors, under enormously energy-intensive and inefficient lamps. The good news is there are indeed ways the indoor-weed industry can clean up its act, and LED bulbs are a big part of that.

Cory W. Ann Arbor, Mich.

With recent reports emphasizing the energy-sucking nature of the weed industry, a reader from Michigan wonders if LEDs could save the day.

LEDs are beginning to catch on in the industry, which is great news for the power grid. But even with these bulbs in use, “indoor cannabis production is an energy hog,” Yorio said. “Anything we can do to reduce energy consumption of the grid is something we should be embracing.” Like what, you may ask? Here’s one idea: System-wide measures like demand response, where the electric plant would coordinate with growers to shift their bright hours to off-peak times, therefore reducing pressure on the grid. And of course, switching over to renewable energy sources such as wind and solar would be better still. These next-level practices aren’t off the ground in a major way yet, but here’s hoping the weed industry will press these changes soon. Say what you will about pot and motivation — a million dollars up in smoke every month on an energy bill seems pretty darn motivational to me.

And then there’s the heat effect. Because LEDs run so much cooler than HPS bulbs, growers don’t need to blast the AC quite as aggressively to keep their plants happy. All together, Yorio estimates, LED grow bulbs will get the job done for half the energy. And yes, the herb they produce is just as good — and often, yields are higher, said Yorio. Sometimes, the light spectrums emitted by LEDs let farms raise even more potent puffs.

Unless, that is, the industry starts greening up its game. And research suggests that’s entirely possible: The Berkeley Lab estimates that upgrading to more efficient equipment and improving practices could reduce related energy use by 75 percent. And just like in our fixtures at home, switching to LEDs can make a huge difference. To find out more about how, I turned to Neil Yorio, technology advisor for a cannabis consulting firm in Denver and vice president of agricultural lighting research at BIOS Lighting. That company sells LEDs, but before his stint there, Yorio spent more than 20 years at NASA studying how to best raise plants on long-term space missions. The guy knows grow bulbs.

Might not sound like much, but all this adds up to staggering electricity bills for growers big and small. That Berkeley Lab study reported that the legal indoor marijuana industry accounts for one percent of the country’s power consumption; some larger growers blaze through $1 million worth in electricity every month. In Denver, which is ahead of the curve with pot infrastructure thanks to its trailblazing legalization of the stuff back in 2012, the marijuana biz uses closer to 2 percent of the city’s electricity, and growing. As more and more states (24 and counting) legalize recreational or medicinal marijuana use, we can expect this usage to increase.

Reefer madly, Umbra.

Q. Dear Umbra,

Can marijuana be grown as effectively under LED lighting and proper climate control rather than energy-sucking heat lamps?

But before we get to the solution, a look at the problem. Typically, growing operations use glaringly bright high-pressure sodium, or HPS, lights (metal halide and fluorescents are sometimes involved, too). How bright are we talking? Try 1,000 watts and 500 times brighter than your average reading lights. HPS lights are useful because they produce the wavelengths plants need to grow, but they do so quite inefficiently, and lots of the energy they tap ends up lost as heat. That means growers need to crank up the AC to keep their greenhouses the proper climate, further adding to their energy bills — and on top of that , many ops also use dehumidifiers and/or ventilation systems, and burn fossil fuels to boost the building’s carbon dioxide levels (a shot of CO2 makes plants, including pot, grow like — well, weeds). All told, producing the average joint creates roughly three pounds of carbon emissions, according to a 2011 study from the Lawrence Berkeley National Laboratory — equivalent to driving a hybrid car 22 miles.
