Grow Light Physics: Coverage Area & Running Arrays with the Mars Hydro SP-3000
Вставка
- Опубліковано 23 сер 2024
- In this video, I test one and two of the new Mars-Hydro SP-3000s in different coverage areas. I use 5 different PAR tests to explain and explore some of the key aspects of Grow Light Physics. Check out the 4x2 and 5x2 PAR tests with one SP-3000 and then the 4x4, 5x4, and 5x5 PAR tests with two!
See below for scene list and links to specific scenes in this video.
Be sure to also see My PAR Test and Review Video with the SP-3000: • Mars Hydro SP 3000 PAR...
The New Mars SP-3000 is a really impressive fixture! If you want to see what it can do - I will show you! If you want one or two in your own grow space - I don’t blame you! Shop Mars-Hydro.com bit.ly/2YbNe6T and use DISCOUNT CODE: CCFC
However, this video is really about Grow Light Physics, the SP-3000s are just the stars of the show. The physics that I cover is helpful to understand, whether you plan to run the SP-3000 or any other fixture.
Don’t be intimidated! I hope to make the science behind grow lights understandable to all growers. I explain all the key metrics and show how we use them to test and evaluate grow lights. I hope that all growers will find the video interesting, regardless of how much experience you have with grow light physics! I hope it really helps to clarify the way that light works in a grow space.

The single most informative light science video on the internet
I am humbled Ausbucket - Thanks for your support!
Absolutely
🤣 rookies kissing ass to this light shill
@@bohaggin5913 lmao im weak
Dr MJ Coco would u say x2 on a square meter is equivalent to a 1000w double end hps ???
Thanks for bringing a scientific approach to gardening.
I decided to go back to school for microbiology and I'll be heading into Cannabis Sciences soon.
I most definitely wouldn't be here if it weren't for the work you've done.
That is awesome! Love hearing this. I wish you much success and Grower Love!
I decided to go back to school for botany, but my school got rid of it so I'm now in ecology-conservation biology. How-where are you going to study "cannabis studies?" Its not legal in my state yet, i don't consume it, but it helped my aunt when she had cancer, and could probably supplement my income with "cannabis studies"
What a great video for us who have hard time understanding some stuff. You make it easy as well as interesting. Major respect for all the hard work doc..thanks
Thank you Smot! Appreciate all of your support and Grower Love!!!
@@DrMJCoco There are two on/off switches on the SP3000. One on the knob side and one on the other side, can you explain to me what these do?
@@bradleyjtobias the back one switches the dimmer on/off and the front one switches on/off the unit in total
Great info all around, and I love how Coco's voice changes when he starts talking about the 4x4 PAR map. This video sold me two lights!
Wow, You put a ton of time and work into this, Thank You, I appreciate it.
Love your protocol and explanation of basic principles.. such as when area increases useable ppf will always increase due to more target canopy but even distribution of photons will always drop off. Most intrigued to see that even umols in center were lower in expanded grow area even though fixture was 4 cm closer. I used to install conviron growth chambers 30 years ago and teach greenhouse management labs at a university and this aspect of your explanation is the clearest, simplest approach i have seen.
So, to be clear . If one wants max production under a single light one would probably benefit from expanding the area as more useable photons will find green canopy to photosynthesize. If you expand too large some the peripheral areas will eventually fall below optimal levels and there will be a greater uneveness of light distribution which will affect uniformity of growth. If space is not a concern one can get slightly more yield per light by expanding the area covered, though yield per sq foot will decrease and uniformity of size and quality of flower will also vary more widely.
Not even to your part of using multiple fixtures but If a grower wants to max production from a precise area however, he will benefit from closer reflective walls and multiple fixtures [within economic and photo biological constraints such as 1000umols [without additional CO2 i imagine or without some way to move the light fixtures to prevent heat damage or light bleaching] though umol/J efficiency will drop and useable ppfs will drop
Thank you!
Yes, your analysis and interpretation of the data seems spot on. We considered the variables you are discussing carefully in developing our formulas for ideal coverage area.
I am really happy to see how much you got out of the video and I agree that the 4cm closer was intriguing. I look forward to having time to work on my next Grow Light Physics video which will look at hanging height and dimming.
Grower Love
I didn't realize how great those SP lights were.. WOW!!
I appreciate you breaking this into comprehensible chunks of information. This is one of the best videos on PAR tests that I've seen.
I only have one suggestion. If you are putting the Mars Hydro SP-3000 in 2x4 or 4x4 grow tent, consider the tent size while air is being exhausted. I'm reading the length of the light is 42.5 In. That is uncomfortably close to the edges of a 2x4 grow tent. My 2x4 tent pulls in around 3 In on each side while air is being exhausted.
Although, you may be able to provide reverse air pressure with an intake fan or build some type of frame to protect your lights, these precautions should be taken when considering a light for use in a smaller area than suggested by the manufacturer.
Geez what size exhaust fan are you using? With a 4 inch from Mars, EVEN ON LEVEL 10/10 it barely pulls in about 1”
Huge respect for all the work Dr. Coco puts into this. Really makes it easy to understand.
Thank you - Happy to share the science and practice of growing cannabis with the community :) Grower Love
im changing to led and couldnt figure out what light to get for nothing ive watched 2 or 3 hundred videos on led lights and would say this video has by far explained & gave more info on led lights then any i have seen to date kudos to you sir this video rocks ty for all the help
Well done doc! It was great to see the way moving lights, adding lights, or moving walls changes the photon distribution, good stuff!
Thanks so much @Spartan! I hope it helps growers really understand light! Thanks for watching it with us :)
Wow, the way in which you put the physics, and the fun into the process of learning, (being able to learn) has left that part of me which appreciates the aesthetics of art, as inspiration and connection, can only say thank-you for the video.
Glad you enjoyed it! Grower love :)
This is a lot of work to put all this info and editing together. Congrats for doing it so well and thank you.
Yeah, it was really a lot of work - I got immersed in it for weeks. Really happy that it is appreciated - Thank you
Glad after all my searching about running and joining multiple 100-250 watt panel LED's, now I finally found the right terminology. That always helps. There's another mystery old technique or two around the internet I have finally found the terminology for as well, one regarding lighting and saving 30% in run time and cost's all while reducing nutrient demand, veg and flower time, but increasing quality, yield, and especially resins and tannins.
2x SP3KS are the new minimum standard for 4x4s because of this vid. I would love to see something beat it. I think the Royal Kush 2.0 for twice the money can deliver 5 more useable watts.
I went through the grow guide a few times before this video and one thing that never made sense to me until this video is the difference between PAR and PPF and PPFD. makes total sense now, definitely going to lower my lights for that high PPFD to get the most from the CO2. thanks!
Awesome - I am glad that it is all coming together :) I may go back and try to clarify the articles a little - thank you for the feedback.
Wow outstanding video. Now I think you are #1. To understand how to use the light no one is doing this
Thank you
One other factor to consider that's not mentioned in this video. Foliage is not flat and it's not a dome. Having an array of lights (as compared to a point source, for example) allows the light to arrive at many angles. So the array will project light farther into the canopy and illuminate leaves farther down inside it. Not dissing the experimental techniques here at all. This was really well done.
Damn! I just got educated! That was probably the most thorough educational video on par testing that I have ever seen on UA-cam! I need to sub up! I'll have to watch it again. Great job on the par testing!
Thank you! This is exactly the response I was hoping for! Really glad you found the info valuable - Much Grower Love
Love this video, you should take all the HPS comparisons and title that video specifically so that HPS users like myself can see exactly why to change. Just bought a Hydro SP3000 and can't wait for the massive heat reduction and all the other benefits once it arrives! It really is a no brainer, Thank you!
Dude fucking Bravo.... crazy how much tech has changed since Metal Halides and Sodiums were the be all end all. I appreciate all the work yall put into this.
Per Mars Hydro: For the SP 3000 and SP 6500 lights, the previous version is with IR and UV chips. Since March, we have moved the IR and UV from the SP 3000, SP 6500, and FC 6500 lights. Also, the new FC-E6500 light doesn't have IR and UV chips. The reason is that these lights' main customers are personal growers who pursue the best results or the commercial project customers; they prefer to independently control the IR and UV lights time, don't need the IR and UV chips on the light itself. Mars Hydro also will issue independent IR and UV lights in the second half of the year.
That is correct, and i have to say it's a bullcrap move from Mars Hydro.. I've read their poll on a forum, nobody voted to remove the UV & IR.. Most of people if not all of them voted to KEEP the UV & IR.. They are straight lying.. In some other post they said: ''UV & IR doesn't affect the grow too much and it's not needed'' but it is.. And they advertised the UV & IR for the same purpose in the first place..
I guess they realized how good of a light that was, and decided to earn more money without raising the price of the light.. It was perfect, now it's complicated and more expensive to buy separate lights..
I'm coming to this 2 years late, and I ahve not been through all of your videos or website. A few observations:
1. Have you run the same test multiple times to see how reproducible your results are?
2. I like the PPE and cost efficiency. Have you considered combining them into a lifecycle cost? A more expensive light that's far more efficient at producing photons from kilowatts might be cheaper for a 5 years lifecycle.
3. You mentioned coming up with a statistical model for quality of the PAR map vs subjective grade. That's a great idea.
4. I tried out the calculator last night for several lights and saw the number of lights calc for a given area. In line with this video, have you done any work on combining lights in different patterns to see what the optimal arrangement is for a given light and grow area format? It will change depending upon the PAR distribution, clearly.
I like you videos a lot. Right up the alley that I've been following with some custom made lights and purchased lights.
I'm a massive science geek. I find you explain things well and offer excellent advice. Keep the reviews coming I really enjoy them. Thanks
Thank you! Glad you like them :) I will keep promoting the science ;)
Wow, Serious work on this Vid, Outstanding Job Sir , Thank You .
This will be great in greenhouses running with the trusses. Less shadow
You deserve a like for all that work
Fabulous info for the community! Can't imagine anywhere else we could get this info. Thanks doc for all your time, research and sharing.
My pleasure! Thanks for all your support :) Much Grower Love
omg your a teacher! thats why this information is so on point. i wish i had teachers like you when i was in school i would have turned out better
Ha! Yes :) Thank you - Glad you learned something! Grower Love
my brain was so happy watching this... and tomato plants even happier
So glad I found your channel! By far the best!!!
Thank you very much for the information! Cannot tell you how valuable it has been!
THAT WAS THE BEST 1.07 MINS...IV SPENT IN 2020💯🔥👍🇨🇦
Oh snap my bad.....
THANK YOU SIR 👍
Wow, thanks for all the work and the info, it was very informative to say the least! You got me considering the SP3000 for my 3x4, I believe it would not be bad at all and could replace my 3 SF1000! It's rare that I see lights for a 3x4 setup and getting lights for this size is a bit tricky... But your calculator and this video did help me figure it out a little more. Thanks again!
Doc, you ROCK! This video is so well researched and presented and so useful in explaining the photon distribution with these lights and will help everyone interested in maximizing growth under artificial light. Great information!
Thanks So Much Bob! Always appreciate your support! Grower Love
This is a peace of art. Thank u .
This just answered a question I asked on the previous video. Thanks!
I was just reflecting on (BOOM! 😉) what you describe in the Total vs Useable PPF to... I'm a photographer and cinematographer and I often struggle to achieve convincing sky lighting. My LEDs are single chip 300w + 600w (Circular) See the Aperture 300d, incredible lights but having all that power in one chip presents the same spread problem as a HPS... You're dependent on light modifiers which lose you a stop or usually more of light...
However, this has got me thinking... We have so many light modifiers at our disposal! I'm used to making do and creating the light I need from what I have. What if we could experiment on more ideal tent geometries and materials/coatings than the standard "Box of mylar' we're all used to. I have a very expensive Parabolic light modifier by Profoto which works optical miracles from a single point. Also, I wonder what an innovative, mechanical light mover could do with a single 600w led chip moving it across the "Sky" of the tent through the day, mimicking the sun's movement...
It would be fascinating to experiment on techniques to save more photons with you but I'm in the UK.
Thank you for all you do 🙏
Thank u lots brother... This is very interesting, educative and helpful video... Thank lots...
outstanding! Great video, It answers so many questions.
Glad it was helpful! Grower Love
@@DrMJCoco Grower Love!
I very much like your style of presentation. I shall be telling the local grow store employees about your channel and this video so as to hopefully get them pointing customers to this video.
Wonderful - Thanks for spreading the word :)
Dr MJ Coco your welcome! Thank you for putting out information worth sharing!
Insane tests and explain, what a pleasure. Just one question, grow tents also have reflective bottoms and tops; would this affect plant growth ? Or exceed the 1000umol? If taking “ideaal” hanging high from these tests
Thank you buddy for such a great job cheers!!!! 👌😍😍
Thank you!!! Really appreciate the opportunity to play with these two fixtures - you have an amazing light on your hands with the SP3000 Cheers!
Not trying to kiss ass, I'm new to all of this . Just went to your site... Great Work ! Wish I would have went there sooner Instead of all the reddit and everything else. Awesome work, easy to understand, and everything is there.. thank you again Sir.
Thanks! I hope to see you around cocoforcannabis. Much Grower Love!
Great information, you guys are awesome.
Love your videos and your website.
Thank you! Grower Love!!
Covering various lighting options, very useful information!
Seems like this would be a banger for a 3x5 or 3x6 veg. Def banger for 2x4 flower
Awesome videos man thanks for all the info, you should do this test with the Mars Hydro FC 4800 in a 4×4.
Look up justintime2grow on UA-cam he did a review on the fc4800 in a 4x4 tent
Look LED light depots in UA-cam he did a 4x4 test with the fc4800
Love the Information !!!!!! Glad I found your channel. Got me sold on the sp 3000's x 2
hi! did you buy it? If yes, how is it? :D
what about the impact on reducing the wattage on the PPF? Is that linear? (25%,50%,75%,100%) Great channel btw!
Actually, maybe it's parabolic (at least in the sense of final yield)... 0 watts = 0 usable PPF but double the watts (assuming you're 80-100% of the optimal usable PPF) and you double it your final yield is likely 0 as the plants die. Just a thought.
Thanks for the light reviews, and thanks for the discount on marshydro. I got the FC6500.
I am hoping to test one of those soon - I expect you will like it. Thanks for the support! Grower Love
IM GONNA NEED THIS LIGHT FOR MY 2x4 AS SOON AS POSSIBLE. U MADE ME SICK !!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!! THANKS
I got it in mines and it's killing it 💪
Got 2 of these in a 4x4 growing cucumbers. I dont even need to run them at full power. They are really bright even at 50% power. Best part is that i can run 2 at 50% which gives the same power draw as one, but with a much better coverage area. They are LED lights on steroids. Only downside is the amount of heat they radiate. At 50% power im running my exhaust on low-medium which is virtually silent and holding a steady internal temp of 83F degrees with a 72F degrees ambient temp. Its kind of a good thing though when non-scorching heat is needed.
Yeah, running dim can actually generate more heat from the driver. Do you have the drivers mounted on the light still - I bet moving them out of the space would really help reduce the heat. Grower Love
Yeah move the drivers to top of the tent. I put a plywood board on the roof to support all the exhaust fan and drivers. I have no motors running in the tent other then the occilating fans.
Thank you so much for this, I learnt alot! One thing though... I'm so intrigued by the 5x4 but with the lights placed perpendicular to the way you had them, you mentioned it briefly but didn't show the par map. I would love to see how that compares as I think you were onto something there 😅
Was thinking the same thing. Also wonder how this light would do in a 3x5
@@S3brandon quite en expense to test it unfortunately 🤣
Really wish you woulda utilized the sp3000 to their max in the 5x5 using co2
So just ordered one for my 5x3 closet.
Great video
best channel on yt!
Could you do a new review please? They changed something with the new SP3000 after March. They removed the UV & IR, and i believe they changed the diodes. I was so sure i would buy this light, but now i'm not so sure after the change.
Hi did you find this out ?
Thank you for such great content
Waiting for this like Christmas!
Hope you like it!
I love this video so much. I'm terrible at science and maths, but Dr Coco makes this info much easier for me to digest.
I took his advice and now have 2 x SP3000 in a 4x4. I can't seem to get the hanging height correct and burned my plants last run. Any tips would be appreciated!
You found out the right hights?
Can’t wait for the 5x5 tests 😃
What would be the best Mars setup for a 4x8 space? Sp or fc? And which one model.
I'm thinking about it I like to try with 3 SP3000, and maybe ad one more lights once money flow better
lookin' forward to it ;) are we gonna see Dr. Coco in this one? would be nice to put a face to the voice ;)
I am shy because I think it would complicate my relationship with my students at the university. Grower Love
@@DrMJCoco makes perfect sense, all good Doc ;) great vid btw, enjoyed thoroughly ;) ...missed the start, so watching that now
Your videos are awesome you show the results were all want to see but I'd be interested in heat tests as well over a number of hours say with different sizes of exhaust fans or something of that matter
Hey coco, great vid! Did you hang the lights at 1 foot from the wall on either side in the 4x4?
Thx for putting in so much effort, but - you guessed it - we wanna know if you need 3 or 4 of those for a 5x5 to have that sweet even par map.
Amazing piece of work put together by dedicated much appreciated part of the nicest community the cannabis community it was and is a film to last for years and many of the people he mentions are boss too.Now that was in depth just brilliant never thought it would be that informative well done Drcoco and collab with migro man all the best people on the internet definitely subscribe to this lot of clever clogs totally recommended
Really glad you liked it and appreciate the information :) We will do our best to keep it flowing! Grower Love
I just ordered one to replace my Viparspectra TC600!!
Awesome! Just wow!
I just look for a light's kelvin rating. Usually between 4k-6.5k.
Good strategy so far to me.
Since many grow lights exceed my budget,
I look for kelvin and buy a light based on that. 6.5k for autum fall crops, 3k-4k for spring/summer
might have to upgrade over my TSL2000 , even though its doing a great job right now
Can you please do a vid on hlg lights
Do you know how many BTU of cooling power is needed for each sp-3000 I’m putting 24 of these bad boys up
Apparently they have recently removed the UV and IR diodes from their products. This changes everything. Smh
whaat!?
Thanks for this video.
Hey man,
What could you recommend more for 150x150cm? 2 sp3000 or 1 x 600 pro?
Thank you in advane and keep going your good work🔥
thanks for sharing.
Please add the preloaded fixture for the Mars Hydro TS 3000, more specifically 2x TS 3000 in a 1m x 2m x 2m tent.
This is without any doubt the holy bible on grow light science
Could you test 3 SP3000's in a 5x5? That's my setup. Based on your calculations *if* you can get an avg PPFD of 1,000 you'd be at 2.5 Photon Efficiency.
Is Photon Efficiency where they get the max. Grams/Watt stats? (A conservative 900 avg. PPF (and now 900 watts) gives you photon efficiency of 2.25, still pretty good (I'm using 900 watts in the calcs) -- Also, why do you multiply Avg. PPFD by 97% to get usable? I assume it's from lost photons due to reflection but is it a constant 97% (or close enough, i.e. 96%-98%)
Overall an amazing video not only from the light setup for this particular light but the overall principles. you might consider a 30 minute video covering primarily the principles and sensitivity of each variable with a few grow light examples (top selling models) to demonstrate this in practice but focus more on how home growers can incorporate this information to optimize their grow and understand what metrics to measure/target and how to use them. A comparison of say three different likely semi-random setups someone without this knowledge might arrive at (light x fixed to the top of the tent vs. the same light at the optimal height and the difference in efficiency or optimal height but under-powered for the space vs. optimal height & watts)
When I bought the first SP3000 it was because of the evenness of the PAR distribution from their marketing materials but I also have looked at up-front cost/watt as a primary deciding factor between two+ lights assuming the distributions are similar. I think a lot of people would follow the same train of through but it sounds like the focus should be entirely on photon efficiency. If photon efficiency = Max. GPW, most if not all lights that quote a max. GPW always say 2.5 -- I guess this may be true for a theoretical maximum but when deciding what to buy it'd be better to calculate what you'll actually expect to get.
Would you consider doing test where you lower lights but use light mover to even out the distribution and perhaps a DLI meter to work out how far you can move a light but keeps intensity at 1000 umols [averaged] without photo bleaching or heat stress?
Absolute pearl , if you are experiencing whilst High
Great but did feel like an advertisement with how many times you dropped the discount code.
I’d love to see a test with a single sp3000 in a 2x4 at either different dimming levels or higher hanging heights. One of the problems many growers experience when using these new types of LEDs is deficiencies when exceeding dli using long light cycles in veg 18/6. Many of us have found that we can increase PPFD and lower veg light down to 15 or 16 hrs or lower PPFD and increase light hours. I’d love to see what hanging height at full power gives an average of 500 umoles which is great for 18/6. Or keep the distance at 19.5 inches and tell us what dimmer %. Or is that simply somewhere around 50% dimming at 19.5 since you were close to 1000 at 100%. Not sure if it’s linear or not. Thank you again for all the work you do. Your first mars sp3000 test convinced me to buy the light. Trying to help the majority of new growers who get those purple stems.
After watching this extensive analysis as well as for the SP-6500, I’m curious what the result would be four TS-1000 in an array. From a cost perspective it looks like it would be an equal contender in a 4x4 setup
So detailed! Question: are the cxb3590 Cree cobs and luminous cobs outdated compared to these lights? I didn’t see any cob results in your website
Watched this a few times. Each time you sound more and more like the stoner boyfriend from American Dad lol
this is classic
This is a fantastic video--thank you so much for putting this all together and making it so easy to understand. I'm excited to use your calculator!
I am still a bit confused about why you use the 1000 ppfd measure to determine hanging height in these tests when you yourself emphasize the importance of light uniformity. I would think that the "trough" effect would be lessened and uniformity would be better in the 5x5 if the lights were hung higher. Would it make more sense to go the other direction and aim to keep the minimum number above a target ppfd of 500 umol/m2/s?
Yeah, I fully understand your point and I agree that the Optimal hanging height may be a bit higher for the 5x5. However there is a tradeoff there... It is true that the distribution is improved with higher hanging height, but the usable PPF goes down (Higher height exposes more "wall" and leads to more reflective loses). So our testing protocol is to hang at the height that maximizes usable PPF. This makes the most sense as a testing standard and leads to comparable test results. But I do tend to agree - in a situation like the two SP3000s in a 5x5, the Optimal hanging height for maximizing Photosynthesis is likely somewhat higher than the height that maximizes usable PPF. I continue to think about these relationships as I develop the distribution formula - I would like to be able to better calculate the tradeoff. Hopefully these test results would still lend insight if you wanted to alter the hanging height. Grower Love
I run 4 of these in array for flower. This video actually inspired me to do so. I have wonderful results even though they call this a veg - greenhouse light. Any ideas why Mars Hydro calls this a Greenhouse light vs bar styles? is it just because of the ease of linking these in arrays?
Single bar fixtures that pack a lot of diodes are great for greenhouses because they can be positioned below a beam and not cast another shadow (primary light is the sun). They still work well in other applications. In a greenhouse the sp3000 would provide enough light for veg but in a tent it is more than enough light to flower.
Nice testing. How will the SP3000 do in a 3x6 and how many will be needed?
Gonna be rockin 2 of these in a 55×50. Just want a little more room than a 4x4.
How's it working out? Thinking about doing the same thing.
@@billyB419 well I'm still getting everything together, just got my lights today. I figure making it a bit wider so I can have some room to put a few fans on my lights and give a couple more feet of canopy space too.
Thanks for the well detailed video and even more thanks for your coco tutorials. No more soil for me. One quick question, 2 SP-3000s would be better than one SP-6500 in a 4x4? Thank you.
Yes better spread. The sp6500 is too powerful for a 4x4
Would it be a good idea to put 3 sp-300's in a 5x5 ?
My same question
Thanks for sharing your work! Can you tell me if there is anything better than running the sp 3000 in an array?
4x8 and 3 sp3000...
Update: 3 SP3000 work very well on a 5x8 grow space 👍😏
How would work a fixture of two sp3000 in a 1.50 cm for 100 cm space. I have an Sp3000 already and looking how to complement for flowering.
Is there a possibility we'll get light spectrums along with the rest of the videos? I've heard the quality from a CMH is better than the quality from any HID and LED. Which according to terpenes levels, it seems accurate. So I'm trying to find an led that does the same/similar thing.
hehe Bingo from Norway ;) tnx man relly nice job . i love the video . it helpt me a lot . i got a 160cm x 120cm tent and i got 2 Mars Hydro TS1000 . so waht to i use i whas tinking 2 Mars Hydro TSL 2000- but now after looking at the SP3000 am tinking of them .. ;) what do you tink is best for me i waht to runn my ts 1000 to in the same tent hmm ;)
ps i found you as i whas looking at vidos from mygrow you 2 are the best ones on ligths . keep up the grate work
