![What's the Best Grow Light for Growing Cannabis? [2024]](/img/n.gif)
Your discussion of lumen vs. par measurement was extremely well done and an eye-opener for me. Thanks!
Fantastic video, guys! It was just the information I was looking for. Could you tell me which ballast and hood cover you recommend (perhaps a video you produced on this)? Thanks!
Great Video!
@growace can I use the par meter to check how much life the bulbs have remaining.
Hey, Can you compare the Hortilux to a new LED grow light? Something like the Platinum LED P300?
Great vid thanks bro
Thanks for the vid :)
What i would really like to know, is the LLMFs (Lamp Lumen Maintenance Factors) on the bulps :)
I've used a 600w Ushio HPS before and the price for one of those were around $60. Good to know there are bulb brands who are upping their quality and keeping costs low. As much as I love Hortilux (used it for a cycle back in early 2010), they are just so damn expensive. Found yield lab bulbs on amazon 2x 600s for about $45 bucks. I'll try them out on my next run. Thanks!
SORCelement I swear by Ushio enhanced Opti red bulbs. $48/600w on Amazon. great value.
you get what you pay for, I've used Hortilux for years, I've tried others but keep going back to Hortilux because they give me better yields, my last grow yielded 2 pounds 13 ounces with one 1000 watt Hortilux super HPS, thats 1275 grams, so 1.275 grams per watt.
Do I need my heat shield or can I remove without doing harm
What would you say is the best 400watt bulb on the market at the moment?
Good stuff
Absolutely loved it. If you ever do another test plz try Genesis hps. Thumbs
Freedom Smoker We just came out with a ballast comparison right now! czcams.com/video/SjxDrVXJeLw/video.html
I'd love to see you do this with some LED lights maybe get some 300w(although actual draw wattage can differ) lights and start with the cheaper yet still quality Mars hydro that can be found for good price on ebay
The U.V. spectrum ENDS at 400 nanometers, and the I.R. spectrum STARTS at 780 nanometers which means this guy is misleading people. Also to note by other comments below, he apparently is biased in that he sells yieldlabs bulbs exclusively. If future viewers are smart enough to read the comments, then hopefully they are also smart enough to do more research.
Great information regarding light spectrum. We are by no means experts in light spectrum or master growers. We're growing enthusiasts that want to share any knowledge we have with the community. We admit some of our information may at times be wrong, as our information is gathered ourselves from research and experimentation. If we ever state any wrong information we'd love to know in order to give proper information in the future.
no he isn't, he still tested all the grow light's to compare how is that misleading? and this video was made in 2015 dude. if you were any kind of smart you would know all HPS light's have red light that goes past 700. it's the blue light that the HPS is lacking
You dont realize how much being under the light can skew the results. Even if you're not casting a shadow over the meter obviously, you are still going to effect the results a lot by blocking light from reflecting off the tent and itself
Agro-Sun Red german made out tested horts by me, several times over the years.
Lumatek and Solis tek bulbs..??
philips green power vs gib lightning ?
250 watt hps subsystem heat shield importance in growth for winter temps
You should do a give away on one of your hps light systems
Hortilux for the win!
inline fan comparison would be good to see! Ballast comparison is always interesting too....
Well_Water Those are great requests! Expect one of the 2 to be made in the upcoming weeks. Thanks for watching.
great! sounds good.
These are considered the basic of professional quality. Thank you for this comparison cuz some of us users are still using this technology
it is pretty widely accepted that 2 technologies are killing LED on the professional side HLG and COB units.
a comparison of some highly hyped LED against HLG and ChilLed?
We're always looking to inform the community. We'll look into how we can properly compare those lights.
You are great at making videos! You should own CZcams.
knowing that the Hortilux has a 12 month life before it degrades and most others don't warranty their lights for 12 months, is the Yield lab light really a better deal if you have to replace it twice as often? also the Hortilux is in a class all by itself when it comes to their patent protected spectrum recipe (25% more blue than other HPS brands), most don't have more than 4% blue.
The most current top best and powerful human tools will likely always have a niche of individuals who don't care about the small cost. They want the best no matter what. Like imagine Donald Trump got into light's.
I run both Hortilux and another brand called "Interlux". The Interlux brand reverse engineered the Hortilux arc tube gases/salts, strengthened the bulb and added a newer type of resistor that is specifically designed and optimized for digital ballasts. The Interlux literally tests within 1-3% difference of the Hortilux every time! I run both so I'm not biased but I'll tell you this, with the Interlux being the same PAR readings and spectral distribution as a Hortilux at 40-50% less price point, I go Interlux whenever I can find them! Those bulbs seriously rock!
Greetings, I am a Hortilux user for about three decades and have not used the interlux bulb, i"m just wondering how long they last? I get about 16 months on average before I get any serous measurable degradation. I used to use a simple lux meter but have an app called corona on my i phone that isnt perfect but better than using lux and when tested against a accurate meter is not totally out to lunch, close enough to measure light at the canopy to maximize without stressing or burning your girls.
@@torrielandsman4625 To tell you the truth, I NEVER run a bulb past 8 months of documented "on-time" before I change them out. So after around four 8 week bloom cycles or 8 months on 12/12 I change them out. With any brand of bulb from Hortilux to Interlux etc there is a difference in spectrum distribution and yield quality/quantity after this cutoff point. By changing them at least once every 8 months you can guarantee maximum output and spectrum coming from your bulbs. At 2,000 hours on time an hps bulb has shifted up to 15% of its spectrum and has lost 10% intensity.
As far as the Interlux RUNNING for 16 months? I'm sure it would but I would never push a bulb that long, there's just no reason to when the bulbs are so reasonably priced. Not to mention, the RETURN you get on your investment by changing more often is so worth it...
what about gavita ? they have been around for years or have people forgotten
+Mr Jugears I don't believe Gavita carries Single Ended 1000w HPS bulbs anymore. They're moving on to DE 1000w. However they still produce the 600w HPS Single Ended bulbs I believe. Thanks for your comment!
no worries keep making them videos, have you got any plans to do abit more on coco or maybe 60/40?
i want to see metal halide bulbs next.
400 par at 51 inch is still good, NO led can do that, maybe the COB's can? i have 1 COB light it works really good
I just use the Phillips globes.. Son-T
same thing with LED pls like growBlue apollo, blackdog or Hydro LED
LED is amazing
yes why wasn't genesis bulbs tested? they are they best light price and par wise. good test.
Patrick Power Jr Hm-- good question. We wanted to test the most common and popular bulbs in the market. Never heard of Genesis bulbs until now. We'll look into it and test it out. Thanks for the comment!
true statement: years of growing with countless brands of bulbs. genesis bulbs failed on me, and not only failed. but melted and fused etc. etc. only genesis, after the first time and dealing with them and getting a replacement bulb, and having them accuse me of user error.. the next bulb did the same thing... total waste of my time and money.
DID I MISS YOU SHOWING THE WAVELENGTH CHARTS FOR THESE? FINE FOR LIGHTING MY YARD.
I think you will find a big difference in life performance between lamps also. Showing Par on a 20 minute warm up on new lamps isn't great info. Where are they at 100 hours, 1000 hours. The cheap lamps drop fast, and tend to have many more premature failures.
Thanks for the great advice. You are correct, we should have used lamps and ballasts with 0 hours of use for a more accurate comparison. There were numerous variables that we were not able to eliminate completely from our tests to create the most reliable results; either due to time constraints, availability of material and space, and limited budget. We would love to see the results of a more reliable test comparison.
Which of these companies the sponsor this test
+Matthew Sprechet None. Straight up, unbiased, non sponsored test.
+GrowAce But "GrowAce" and "Yield Lab" are one and the same... Not saying you altered the results, but Yield Lab is a GrowAce brand, and you are essentially advertising the Yield Lab products in your videos. With you not acknowledging the affiliation, I am suspect of your claims. In all truth, this is a sponsored test and not really unbiased. There is motivation to portray your brand in as positive a light as possible, and there is no law against exaggerating reality in advertising.
+Des420 Yeah, the Yield Lab is a GrowAce brand and I get what you're saying. In all honesty, this test was for our customer's who wanted to know how ours stacked up to other popular brand bulbs. Instead of telling them how well our bulbs worked, we wanted to create a video demonstrating it not just for ourselves, but for people on the fence. All companies can claim that they stand behind their product, but we wanted to go above and beyond and show it. Is this test perfect? No. But we did an honest test with no attempts to alter the results because we know people who grow are smart people. This test can easily be replicated and we knew that going in. So in a sense, it was sponsored-- but the money was used towards purchasing the other bulbs, the PAR meter, and we are investing in a spectrometer to better our results for tests in the future. Hope this clears things up. I love feedback like this, so if you have any suggestions on what we should disclose on our next test or other factors we should consider, we want to hear about it. Thanks again :)
+GrowAce Nope. I can't ask for anything else as far as disclosing more than what you already did. In fact, I'm really happy that you were forthcoming with the info once it was brought up.
One thing I'd like to know though, is do you plan on selling just the Yield Labs bulbs on Amazon again? I was interested in trying a few out based on your tests, but could only find an entire grow kit.
+Des420 We currently only carry them on our main website, GrowAce.com. Hope this helps.
Genesis should be in the comparison for sure
genesis is the best 2800 par + looked on ebay hortilux is going cheapest atm on ebay in bulk
I wanna see blue metal Halide flower 4000 k to 10000k every thing that is between!
So at 51 inches the hps outperforms led lights 4x times the price,got it!
My concern is you guys seems to be the only guys selling this buld at this time and we have no clue of the reliability of these bulbs. Hell I would use them exclusively if they are only a little under Hortilux in the PAR readings but actually higher in lumens. I am a skeptic of cheap bulbs when it is such an important part of a grow. The last thing I want to do is have bulbs start failing in the middle of a grow due to being cheap Chinese junk and then just spending the money for the old tried and True Hortilux and realizing I just threw my money to n the toilet.
I think I will have to wait for feed back from folks who take the chance on these bulbs before I invest in them
At least he said one truth, hortilux is the best
It says Digilux has a 1016 average rating over the 1010 by Ushio? Also, you guys exclusively sell yieldlab so it makes it a biased test. Sending a request to Monster GArdens to see if they will test your bulb and findings..you're bulb is made in China..
Mrodogg73 We look forward to their comparison test. Just a heads up, Iphones and Samsung Galaxies are made in China as well.
Growace..lol..Samsung is actually a Korean based product mosltly manufactured here in the states. Apple IPhone has various parts from several manufacturers yet much of it is also assembled and manufactured here. I'm not sure how that correlates to your yieldlab bulbs. I hope they take the time to test the bulb also and see how it does in comparison. Chinese products in terms of hps/mh bulbs are usually poorly made. Im surprised at your results. I've ordered 4 bulbs to run a test myself and see how they do.
Damn potheads. PAR describes a type of light, not a measurement unit. The appropriate measurement for this test is photon flux and photon flux per watt, in the wavelength range of 400-700nm, the actual units are micromoles/second and micromoles/joule.
As you are using a fixed measurement distance and controlling variables fairly well(no mention of temperature or monitoring of line voltage, current, or power factor, which can vary significantly) and this is a relative comparison within a fixed set of bulbs you can substitute PPF [photosynthetic photon flux] with easier to measure PPFD [photosynthetic photon flux density]
Astute observation. You are correct that some of the terms used are not the correct scientific terms pertained to measuring physical phenomenons. These terms are in correlation to our mass audience and what we have found to be the terms they associate to these tests. We have since incorporated testing temperatures in degrees Fahrenheit, while continuing to omit testing current draw, as it (in theory) can be calculated based on used parts, and is of less importance to our mass audience.
ballasts
Ballasts!
what? 1'd
Son t agro by philips are the best bulbs ever made 30 + years of experience .I would not use anything else .plus a 400 watt son t will cost you 30 bucks
Have a hard time believing Yield Lab better than Ushio. Cmon.
There are possibilities of variations that could have altered the readings, such as inconsistencies in method of measuring, defect in the meter, or accumulation of surface particles. These elements and more could have played a part with inaccurate data. However, with the data we collected these variations and inaccuracies would not have a significant change. Keep in mind, that the difference in their PAR Units is not very significant, and would be very difficult to tell the difference without the use of meters. The main highlight we want to emphasis is not which provides more light output, but rather which is best for you in terms of light output and cost.
If the differences in PAR output is minimal at best...its a no brainer to go with the cheaper bulb and changeout every 2 crops
Fishy
Ballast Comparison is now up!

I love Harry Potter😍
stupid and misleading... yes you are measuring PAR but what is the spectral distribution for each given bulb. If all we care about is PAR then all light would be red. Your test is only valid if the spectral distribution for each bulb is the same which it is not.
