The Truth About LED Grow Lights
by Nebula Haze and endive |

You may or may not know about the LED grow light craze.
Today, I'll be answering the following questions:
- Why is there so much controversy about whether LED grow lights even work?
- Which companies, if any, have the best LED grow lights (specifically 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.
The truth is that both sides are right.
Now, I'm talking about grow lights made of light emitting diodes, commonly known as LEDs. You may have seen ads for these lights, which often resemble UFOs, and claim to be the growing technology of the future.
 
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.
After that, LED development has proceeded rapidly.
LEDs, which were originally tiny and dim, have doubled in efficiency and light output about once every 36 months since the 1960s.
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.
Which has all led to the development of LED grow lights.
At first, no one could successfully grow anything using LEDs. Each individual LED is relatively small and produces only a specific wavelength(color) of light, and we couldn't seem to successfully replicate the proper strength and color of sunlight.
But through trial and error, we've now developed some wickedly effective LED grow lights.
And LED grow light systems have some pretty sweet benefits:
- Extremely efficient and uses a fraction of the electricity of other grow lights
- LED light systems run extremely cool and most do not need you to do anything to control heat
- Most LED light systems can be plugged directly into a regular power outlet, and don't need a ballast or special light socket like most other grow lights.
- Some growers claims that marijuana buds grown under LEDs contain more THC and other cannabinoids (which may be because marijuana produces stronger buds when slightly stressed)

Now, it's a proven fact that LEDs can be used to grow plants from the beginning to the end of their life cycle.
I know this is true because I have personally have grown marijuana plants from seed to harvest with an eLoofa LED light system.
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.
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.
Based on the experiences of some of my fellow growers, I discovered many LED grow light systems just don't work for growing marijuana.
After doing some research, I got an eLoofa 90W light in 2010. I got a second one a few months later, I've grown 6 crops in total under just these eLoofa panels, growing two small plants under each eLoofa.
My yields under the eLoofa 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 eLoofa were always dank and sticky.
The incredible quality of the buds kept me trying to find ways to up the total yields.
Plus I was saving money on my electricity bill (electricity use with the eLoofa was minimal), and there was no heat to speak of, which really simplified the heat situation in my tiny, tiny closet.
I was pretty satisfied with the results.
Then I had the pleasure of running into other growers who have used specific models of LED grow lights that work FANTASTIC.
So LED grow lights can work, but at the same time, it is true that some work much better than others. And there really are dishonest companies out there who probably just slapped together a bunch of LEDs, which no consideration to what's really needed to grow a plant, and these LED grow lights will never grow anything, no matter what you do.
In today's article, it is my goal to share with you the two brands and models that have been proven to work great for growing marijuana, so you can skip the trial and error.
eLoofa Panel:
Learn more about the eLoofa
Verdict: Great for the small-scale grower who wants to grow 1-2 plants in a closet
Price: About $200
Pros: No heat, low electricity use, incredible quality of buds produced (seriously, 10/10), can grow two plants with one eLoofa panel
Cons: Smaller-than-average yields, leaves closer than 15" to the light can show signs of light stress.
Here are some pictures of the plants which were grown primarily under the eLoofa 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.

Pro-Grow 400
Learn more about the Pro-Grow 400
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."
Price: $550 (for one of these efficient monsters)
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.'"
Cons: Expensive initial investment
The following information and pictures are here thanks to endive from GrowMedical420.com. Definitely check out his website out for tons more pictures and to get updates about their current and future medical marijuana grows!
The Pro-Grow 400 easily covers a 4' x 4' area, and up to 5' x 5' with a little plant rotation & shuffling.
Ideal setup for a grow tent or closet is to have the taller, lanky plants toward the edges of your grow area with the shorter and denser plants located center, directly under the lamp. You may even raise the 'edge' plants up a bit so they are closer in height to the LEDs.
Keep Pro-Grow about 20" above plants. The days of having to keep your LED grow lights just inches above your plants are over.
Suggested Strains that have worked beautifully with the Pro-Grow 400 (with pics to prove it... click for closeups!)
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.
 
Blackberry: Quickly gains mass, trichomes & aromas! Fast growing, dense colas from top to bottom, trichome coated & smelling of ripe fruit and jet fuel.
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...
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!
I hope you enjoyed today's article all about LED grow lights!

Q: We have been trying this for some time now, but haven't gotten the quality results we should. As of right now, we have a T5 light system. What seems to be the problem with these lights?
A: A T5 system should work great for the vegetative stage of growing marijuana.
I'm assuming the problem is you're plants are surviving to harvest but you're not producing the yields you expect.
If the problem is that your yields are small, the reason is lack of light intensity.
The size of your buds is heavily influenced by the amount of light, and marijuana buds want a lot of light.
The light produced from a T5 does not have the needed intensity more than about 8"-10" away from the bulb.
You have a few options.
1.) Bend and manipulate your plants to have an even horizontal top canopy so you can keep your T5 2"-3" away and have most of the plant within 8-10" of a light at all times.
2.) Plug in additional CFL bulbs (2-4" away) whenever you notice any 'dark spots.' Remember, you want the entire plant bathed in light, so extra CFLs can help you provide light to the parts of the plant that are too far from your T5.
3.) After the plant has mostly stopped growing upwards, you could pluck all the leaves of the bottom half of the plant so she's only spending energy on buds that are getting adequate light. This will help you get the most of what you've already got.
4.) You could upgrade to more intense lights (such as HPS or LED grow lights) when your plants hit the Flowering stage.
Good luck and let me know how it goes!

Reply: Nebula, you're right about the plants not dying, they grow to maturity, just not the yield there should be. I will try out your suggestions. Thank you so much! |
