Finally been waiting! Thank's.
Awesome video! I love finding science-based resources like this for growers. Please keep the videos coming!
Nice work , I've been running this light since August and I can tell you it's absolutely killer , I'm in a 57"x57" tent , a small 5x5 , it's about 2-3" from each side , the performance is spectacular ! I had a CMH de 1000 and this light grows way bigger denser bud's , right out to the edge , I switched in mid flower and my girls went ballistic , all branches went straight to the top .....insane growth ! $990 , I paid $1300 Canadian but if it died I'd buy another immediately !
Really
Love when there is light videos with such scientific data and not manufacturing marketing data.
Finally!! Thank you so much!!
Great video. Looks like a really good light for the money.
I was pretty impressed with how big and the density of the buds in my last grow with this as well. Definitely a good fixture.
What kind of yield did you generate?
@@eyesopen9477 well, I just mainlined and really wasn’t going all out for yield but 1.4lbs just with 4 plants in a 4x4. Can easily pull 2lbs if scrogged. You can go check out my last grow if you want with my other 19,000 subs.
@@RowsOfGreen how far from the canopy did you hang it? I want to run it over 5x5 and not sure about best height. Thanks
@@RowsOfGreen dry weight?
@@bogdansmal9952 well I hang it high and let the plants grow into it. Probably ends up around 20” above the canopy in flower.
Great video..i particularly found the par meters or quantum sensor info ..very helpful. Seems mars made another quality fixture.
Much Grower Love Smot - I will keep trying to find new fun things to discuss for you in the videos!
I honestly think that Apogee's 380-760nm ePAR sensor (or 389-761nm PAR-FAR) is the best for representing the PAR output of a growing light. Please see the Mr. Bugbee's video about the new definition of PAR and this latest sensor:
ruclips.net/video/IJCLxCZ5qrI/видео.html
I'm very surprised if after watching this video you still think that PAR is best to be measured between 400-700nm.
Awesome light subscribed 👍
I love my 6500! It’s a absolute beast
Hi , you think it is enough for a 5x5 ? Tks
@@Hyerven absolutely. It’s a huge light. Way way too much for a 4x4. Hang that sucker at the top of a 5x5 and it’s bright
Awesome light!
Much love bro👍👍👍🤩🤩🤩
Got one of these going and plants like it.
Can't wait for it. Although I'll buy the SP3000, solely because of your in depth review. I have 2 questions, do you have affiliate in the EU(especially in the UK)? Second one, do you have a recommended hanging height for CO2 (I want to achieve a 1500 in the middle, instead of the 1000 what you used). Thanks, buddy and keep up the good work
i got my sp3ks last month. youre gonna love em
Thanks for your work! I bought 2 SP 6500 based on your numbers for the lesser light. I'm so happy with them. Can you test it in a 4x4 at different(or appropriate) strengths? I bought 2 for a 48 and operate it at 75%. The light is so even as it it is alsmost the same size as a 4x4.
Hi guys , do you think this led grow light is enough for my 5x5 ?
I love my fc6500. It’s super bright
Thank you 🙏
You’re welcome 😊
I just picked up the fc 6500, with the lm 301h diodes, is there much diff beetween the "b" and "h" diodes??,...Thanx
Should i choose this one over the FC E-8000 for a 5x5 tent for max yield without co2?
I begged him to make this video from day 1
I’m glad I bought one last month after watching this video, lol.
I like this series from Mars. So much that I grabbed 2 x 6500's and 2 x 4800's (they were cheaper then I believe?). No complaints about the products. That said, Mars Hydro has pretty terrible customer service and I didn't even have any issues with the lights themselves. I think I'd still recommend these though. They're solidly built, put out a lot of light and are still a good value compared to other, similar offerings.
You still use them?
@@TopPi752 Yeah. I think the newer versions have better spectrum now, but they’re still going strong.
I have the FC 6500 in my 4X4 tent it is real good have to be careful you do not over do it
dude i wish you literally had every grow light to review lol. literally the best LED light reviewer imo and website calculator is sick too. been very helpful for me to understand LED's better. However I got a quick question. for a 4x4 would you go for either 2 x sp3000 or 2 x ES180 v3 ? Im leaning towards 2 x sp3000. but the es180's looks pretty nice
x2 sp 3,000s bro. The Electric Sky 180s wont be strong enough for a 4x4, you would need 2 of their ES300s for a 4x4. Ive had a few of my friends return their electric skies and go with another brand and style of lights. They did not like them. Hope this helps
@@joint-thehuntsman would you use this light the Dr is reviewing or 2 SP3000s for a 5x5?
@@silvernatedogg i would use this one for a 5x5. The 2 sp’s are for a 4x4 area
@@joint-thehuntsman thanks ghost! on Mars' website they list a single SP3000 as adequate for a 4x4 veg or a 2x5 flowering light. DrMJ reviewed the SP3000 and gave it phenomenal ratings for PPFD.
@@silvernatedogg Yes, but they always exaggerate the footprint. You need x2 Sp3,000’s to adequately cover a 4x4. Trust me my friend. I been growing for 13 years. Im @jointcustody_seedco on IG
thank you for the great review ! your work help so much ! in begin I think that FC6500 is the best for 5 by 5, but after your review with 2 SP3000, I think that the best PAR map can be get with 2 SP6500 on 5 by 5 with lower voltage. did you recommand it Dr ?👨🔬
What do you mean by "lower voltage"? I don't think the operating DC voltage of the fixture matters because these are all electrically safe products. Anyways for 5' by 5' 2 x SP 6500 or 3 x SP 3000 are also nice options (2 x SP 3000 is enough if no CO2 adding). It's a matter of taste thing 🤷🏻♂️.
To clarify, this FC-6500 is a too weak for 5'x5' if you want to use CO2 and/or get maximum yield. I think it's better for 4'x4', but then it might reach too close to the walls (if you for example have something attached to tent's frame). So for 5'x5' I would personally get 2 x SP 6500 or 3 x SP 3000. But this FC-6500 is still a very nice light and especially the efficiency is super good.
You prefer that one or the sp 6500?
Have you done a review yet of the KIND XXL1000 LED ? I have that light arriving today along with a Gorilla 5x5 SuperRoom Grow Tent with all accessories.
Any chance of getting a discount code that works on the Mars Hydro UK website? 🙏 Great vids btw 👊
Hi ccfg can you tell me when you say 1000ppfd is the maximum usable light. if using co2 does the usable maximum increase. Also how you work out the min and max yield available is this with or without supplemented co2 and if no could one expect even higher yields
The 1000 limit is assuming no supplemental CO2. You can go up to 1500umol/m2 with supplemental CO2. When the PPFD is above 1000 a good rule is to match PPFD with CO2 PPM = at 1500umol/m2 you should have about 1500PPM of CO2. According to the data published by Chandra et al. 1500umol/m2 with 1500 PPM CO2, should be more efficient than 1000umol/m2 with atmospheric levels of CO2. Therefore, if you ran at those levels, you could multiply our harvest estimates by 1.5 to estimate yield.
Got 8 of them, super impressed. Wish the price would stop fluctuating so much I’d like to pick up a few more
$1500 each in Australia. Want to upgrade from hps but the price doesn’t make it worth it .
@@aussiegrows8096 it will with your power bill decreasing
@@teenice894 from what I see I would need the fc6500 for the same area as a 600w hps and it actually runs 30 watts more. So no saving there
@@aussiegrows8096 600watt hps for a 5x5?
@@aussiegrows8096 also LEDs run cooler, so less power keeping temps in check.
In a 4x4 would you raise it 24 inches at 80 percent ?
Will there be a review of the FC-8000?
Mars Hydro recommends the best hanging heights for different stages in the manual but they don't state at what power to set the dimmer at. Do you think they mean at 100%? I spoke to people at Mars Hydro but they all say different things depending on who you talk to. Based on your test what power should a vegetative stage be at 18 in?
I recommend my recommendations over their publish stuff. Yes, 100% the dimmer should be reserved for the seedling stage.
do you plan on reviewing the HLG scorpion diablo or 650R?
No, HLG is the only company that has specifically said that they do not want me to test their lights.
Could you please do a review of the high end Aelius redd LED
Next up spider farmer sf 7000 btw your doing great work keeping these guys honest
I own a spider farmer sf7000 . I purchased it before I learned it doesn't have IR chips like it's smaller sister sf models.
Nice sharing
Anybody else hit the like button as soon as the video started?
What dim setting are you dialed to in order to have 621 watts....is there a calculation to find that?
That was 100% on the unit that I tested. There is some variability from unit to unit. You can get a power meter to know exactly. Grower love.
Have you tested the up dayday uu4000
I’ve gone the longest time without a par meter. I don’t know why because how many $500 have we spent to this point. Lost count long ago. With that said I need to get a good deal on a good meter not a lux meter and convert it to par. I’ve got two lux meters I don’t use them to much hassle even though it’s not hard to do. What’s the best Par meter for the money that will get a home grower everything he needs in one package at a good price point with a warranty?
Measurements of different heights where the edges and center get 1000 µmol would enable you to accurately shape your canopy or scrog into a slight V-shape or shallow inverted pyramid shape, and put your taller plants where the readings are lowest so they are closer to the fixture, or if your plants are all the same height, raise the outer ones in the weaker light zones by putting them on blocks until they are receiving acceptable levels.
So with the light stationary, if you had a reading of 1000 µmol at 16" in the center but at the outer edges you had to have the PAR meter at 12" from the light to get a reading of 1000 µmol, then you would have a slope of 4" height difference from the center to the edge to shape your canopy to, and have uniform coverage at 1000 µmol.
Unfortunately, it does not work like that. There are only so many photons to spread around.
Or put it in a 4x4 and dominate lol
Can it fit in a 4x4?
This in a 4x4 slightly dimmed would be amazing!
It is!
FC4800 is made for the 4x4 I believe
@@stevep4236 It is and would be very nice. The But the edges of the PAR map do drop down quite a bit due o the 33" x 32" size. The FC-6500 is 44" x 43" so the coverage would be outstanding was my point.
@@gregkramer5588 True, I would rather go with more power as well
@@stevep4236 dimming it slightly pumps on efficiency and longevity both also! Just the up front cost is the downside of course.
I have this in my 4 x 4. It crushes.

I haven't seen you do any hlg lights yet like the 600r spec..
Well tell HLG to send him a light and then you'll have your review.....all the other companys sent him lights......I wonder why HLG don't send him the light as he has the most accurate test out of all testers.....but yet they send them to ppl who talk specs and do half ass reviews with bias opinions...nothing against HLG I'm just saying

Which one did you decide to go with?

I would like to see you do a review on the HLG Scorpion Diablo.
check migro on youtube. they tested it with very similar test rig and same meters and calculations.
Tell HLG to send him the diablo
If money isn’t an issue which new led is the absolute best?
Optic Led 650S my friend. This light is in a class of its own
Go with Lumatek or photontek. Real 1000W German engineered. Enough said
Can you make a video on the optic led lights, they have high claims on their lights I would like the see actual numbers on your video
I saw some anecdotal evidence that they are not to hot on support. Just one off but the guy owned quite a few of them and was not happy.
As someone who’s used both they’re both awesome I’d say optic had frostier nugs
No ir in this fixture ?
I have a 4 x 8 tent I can't make up my mind on which one fc6500 or fce 8000 price where I'm at there the same. What's the difference? Which one do you suggest? Anyone??
I am working on a comparison video of the 9 5x5 fixtures that I have tested in the last year. If you can wait a few days, I think it will help answer your question. Grower Love
@@DrMJCoco thanks so much I will definitely wait for that. Also thanks for all the info you provided, I have learned a lot. Thanks again
Would these out preform a 600 w hps.
Yes! Almost twice as much light as a 600w HPS
I like this company, they started out with some cheap amazon light but even then they we’re better than average, now they’ve realized people rather pay a bit more and get better results, and man did they listen
You say it's to much for a 4x4, but could it still be used dialed back?
Yes it can....the light itself would just be a tight fit from wall to wall
@@shamelbennett3835
Thanks
It fits perfectly. It’s what I run in one of my 4x4
@@RowsOfGreen
Thanks, what if any issues have you encountered?
how come companies dont let light maps decide where the diodes are placed. instead of normal even spread where the center is always twice as bright
A few companies have or are trying this - with mixed results. I will explain about the tradeoffs of doing this when I review the GeekBeast Plus.
Pretty please do Spectrum King LED SK603, super ultra instinct thanks. Infinite blessings Dr. Light
Please test this light in a 4x4, I'm very curious
Can this be used in a 4x4
Yes but it would cover your tent from wall to wall almost a tight fit
Most people wood use it in a 4x4 my freind
Seems like a good light but I think there’s better lights out there for the same price with better coverage. Have you tried the geek beast 630w?
I just tested the new GeekBeast Plus. It is more expensive than this - by quite a bit. I am not convinced that the PAR map is better - in fact the PAR map for the GeekBeast is worse on the edges. I do agree that there are other decent 5x5 options at the $1000 price point. I would consider The FC6500, the Photontek X600 and the Grower's Choice ROI E720 all about the same price (after discounts) and all have strong selling points.
@@DrMJCoco nice can’t wait to see the video.
Dank light co is another good light as well
I hope they give you the Scorpion Diablo to test
Justintime2grow did a review on one, he doesn’t do as thorough of a review as the dr, but it’s good info.
Is it even better than the roi 720?
The FC6500 is more efficient. The ROI E720 draws more power and puts out more light.
why doesnt this one have the uv/ir chips? i dont see any purple diodes
Some don't have UV&IR...and Mars is making them now without UV&IR on any of there light's some none will have any from now on is what they told me personally. UV isnt enough to do anything in them its 1 diode on each bar so 8 total.. Geekbeast has 25 UV diodes and you can turn them on and off separately.
ok, thanks for the response.... just trying to figure it out....i'm guessing the light that i just ordered wont come with the uv/ir diodes then.
@@dye39 What light did you order?
@@macpac3803 fc 6500
@@dye39 It might just depends I told them I wanted UV&IR and they sent me the one without,but offered me to ship it back to switch but that's to time consuming.

Why is the FC-6500 $100 more then the FC-E6500? Dope vid btw
FC uses samsung diodes and FCE uses bridgelux.
What bin are the diodes 🤔🤔🤔🤔
Lm301b samsung
Shamel Bennett are those top bin Samsung diodes ?
Yes they are
@daveking777 Yes, although not the latest one. LM301H is the latest(keep in mind, I researched it almost a year ago), but it costs significantly more, and it's just a little bit more efficient. Even the predecessor of the LM301B,the LM561C is a really efficient one, and nowadays (if you can find it) is really inexpensive compared to the newer ones.

Mars hydro have increased prices by 20%-25% here in uk over past month.
It is probably a short term change - try to wait it out. February is a tough month for supply coming out of China (Lunar New Year)
@@beaubridgeman5522 479.00 usd?
Same in Sweden. 1200 dollar for this light. Rather wait or buy something else.
The SP3000 wen't from 2995sek to 4800sek, NO WAY im paying that 😂
If the corners are below 500, you're getting by with being under lit. This is a 48x48 light, with corners above 700, like they should be.
I disagree. corners at 700 is almost wasteful. It is nice to get all the corners above 500, but it a 5x5 there are not many fixtures that can do it. But that does not make this a 4x4 light... 16 sq feet is a lot less than 25! To be very fair, our calculator gives the actual coverage area that the light is best for - for the FC-6500 it is 22.7sq feet.
@@DrMJCoco l agree this would be great for a 4x4. Dim it down till you have 1000 in the center and the efficiency is going to be outstanding, less heat, better coverage and possibly longer life span.
@@DrMJCoco I have learned nearly everything I know about lighting from you and Shane at MIGRO. And I agree that 500 in the corners is perfect. With your tutelage, and your PAR map of the Mars Hydro FC3000 in a 36x36, I knew I would get 700 in the corners of my 32x32. So with the center down at 800 for terpines sake, my corners are 500. In the evaluations, and even the calculator (BIG FAN), some, or more weight should be given to even coverage. The SF4000 would fail.
LOVE your channel 💯
@@olysean92 Yep - I am working on a harvest estimate formula that adjusts for the distribution of densities across the canopy. It is something I have been thinking about for over a year. But for the time being, I agree that the main thing you are buying when you buy a grow light is the PAR map - and distribution is certainly more important to growth than Photon Efficiency.

This would be best suited in a 4x4.
The latest models also have UV and IR Diodes!!!!!
No, just more warm white and more reds better for flowering.
@@RowsOfGreen I have one and it has the UV and IR, it seems to be hit or miss on the orders the old stock is still circulating and that's why people are still getting the old ones which were only 3500k, 5000k, and 660nm.
The Mars Hydro website doesn’t specify this unit comes with IR and/or UV diodes. Which seems like a big flaw with this unit considering those wavelengths cause a defensive response producing more resin/terpenes. It’s why I stuck with MH/HPS all this time, quality over quantity
No UV needed. It is a myth. Proven by scientist Bruce Bagby. But I would like to see infrared 730nm. Or will scientists prove in a year that infrared is also not needed?
Ok, that's it. I'm gonna build a 4.5 x 4.5 grow space and hang this at 20"
