5 years is a long time In the Cob Universe.... Big Up Gromau5.... NOW in 2022 we Have Sean from Migro...... 👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍 I still come back to your Video Tapes....... 👍
I've watched this vid 20 times with 100 pauses. I bought the 4+1 kit. I assembled it & plugged it in. It worked like gangbusters. I'm using all 5 cobs spread to 12.5in on center. The 4 edges are cantilevered out slightly & should bounce off the 3x3 tent walls; like I saw them do in another of your excellent PAR reader viddies with the light mover rig. We'll see how that evens things out. I sure appreciate your content, Sir. Thanks for the forum posts also. Cheers
Was trying to figure out how to configure 8 COBS per 4' x 4' spacing and then I had an idea... Three strips of (4) COBS more evenly distributes light.. 12 COB setup likely not too overboard either if you were to crank em down but maybe too much??.. How is your 12.5" spread working out?? That spacing would allow me to stick with my potential 9 COB layout.. You getting good par readings with that spacing??
Thanks for your question, Atrociteeshirts. I couldn't be happier with the spacing. I don't have a meter, so I was going off of Growmau5's figures. Six months later I've had a chance to adjust the cantilevers & take notes & pull a harvest of good size satisfying buds. I would build it the same way if I had to do it all over again. Cheers!
Hey excellent!! Been pondering an adjustable system down the road.. Not something like a track system.. just something that would allow some adjustment and expansion of maybe 3-5 inches per cob to accomodate some experimentation.. Glad everything is working well for ya brotha!!
Growmau5: Awesome video! I built this. 1/16" stock is just fine. You need to take some leftover stock and put gussets ( 4 each ) 1 in each corner where the center light and materials join. I would recommend that even if you build it out of 1/8" stock. Once you cut the slots, there is no more support for the crossed piece. Love your videos!!
It looks as if two of these assemblies with the longer aluminum and cobs spread out in a 4' x 8' tent with reflective walls would be a kick-ass setup. Great work and can't wait for the next video.
I'm a total 100% newb and i've been seriously thinking about doing a grow now for about a year. I was going to go with a 400w hps in a 3x3 until i stumbled onto your channel. I knew diy led was a really good way to go, but never would have thought of attempting it myself without you walking me through every step on this channel. I really appreciate that, and i think that i am going to be happy that i went this way when i get my first power bill. I am trying really hard to stick to a budget. I was only going to drop $150 on the hps, i realize that now i have to stretch that a bit, but i would still like to keep the initial investment as low as possible. It seems like something that would be easy to upgrade once i had a few successful grows under my belt. One area that i think i may be able to trim off a few bucks is on the chip. Is there any generic or non cree brand chip that i could plug into this system with similar results? I am also interested in what kind of setup i would need to run in cxa2530 or cxa2540 to obtain similar results to this 200w 5 cxb3070 set up. My last concern is with color temp. The cree cobs seem to cost way more in 3500k than other color temps. What kind of dropoff in results might i see from using a 3000k or 4000k vs a 3500k?
Something to put into your calculations would be the intensity of the light to depth of plant penetration. I believe LED lights have very weak light penetration power to penetrate a canopy thicker than 12'''-18'' and they have to be very close to the plant roughly 6-12'' to get the most out of them. If they are not spaced perfectly you will get hot spots and other areas with very little light. I have a great idea to try with LEDs to help fix this problem I just dont have the money right now to try it myself, hit me up if you are interested.
nice video, i am experimenting with no centre cob and angleing the rest in a bit, thying to get a more even spread. a lightmeter like you are using in the video would take out a lot of guesswork .........can you tell me which one you have and if you are satisfied with it..........thanxx
What if you remove the center reflector? I'm wanting a 5 cob for my 2.5x2.5, but going with citizen 1212s with a hlg 185-1050 think this would be good size for my tent?
Why do you wire them in series? This divides the voltage by 5? Why not in parallel? So you get a driver at 36v that gives 600w and put a bunch of cobs on for example the Cree if you wanted to run them at 100w you could put 6 on one driver as when you wire in parallel you divide the watts.
Yo Growmau, Do you get a advantage if using a lens vs a reflector? I would like to see a side by side lumens test at same drive current. Are there other advantages other than protecting the cob? Do you need a larger heatsink due to the lens retaining heat inside at the cob? What are the advantages and disadvantages?
Would it be better to sacrifice some efficiency and use higher drive currents to increase photons. COBs are much cheaper now and you really do not need 50,000 hours at the cost of fewer photons.
Hey...I'd like to mount the driver on the angle rather than remotely. I've got a 30" x 30" personal grow box I'm building and I was going to leave about an inch of space between the fixture and the walls of the box so 29" long. Do you think that would be possible off the top of your head? I like the 5 light fixture. What is the HID equivalent of this configuration? Which cobs would be best for veg and flower? Thanks!
Ik you said you're gonna be doing a cutter config for a 4x4 with 10 is there any way you could compare the measurements from that compared to the 4x4 12 cob setup.
Hey dude I first want to say thanks for all of your videos. I'm looking for a little bit of help I have a 3 by 3 & a half by 8 foot closet that I will be using it I'm hoping that you can help me construct a Cree LED light that will be best for my area. Is there anything that you can do?
correction to my previous comment, these cxb cobbs are 90 watt, to what level do I drive them for efficiency and heat keeping in mind producing high intensity (most efficient cobb use) for a six cxb 3590 Cob build, what driver do I need to drive this properly
Because the centre COB creates a central hotspot. Would it be wise to raise the centre cob so it creates extra par for the corners?. Might make the frame a lot more complex though.
Hey brother! Given your experience with these COBSs, would you object to a 9 COB on a mover over a 4x4 area. Basically a slightly rectangle shaped fixture. Gonna have some cash on hand here pretty soon!
Thanks a lot for making this video! I know it's old and probably you won't answer but for a 2.6 x 2.6 (80 x 80cm) grow tent with a similar 5 COB setup, what do you think about making the bars about 27" long? The heat dissipators are huge too! Thanks again!
Hey growmau5 i know you barely have time to read all these comments, but if you notice this one, i've been wondering about you mentioning that CMH are 42% efficient at converting electricity into PAR light. I've been looking forever for more details about this, but i can't find anything online. Could you point me towards the right direction? Pretty please?
Hy. Great Job ;-) i´m planing a 6-COB light(36V/1400mA each) only for blooming and not sure which temp to choose? All in 2700K or 4x2700+2x3500 or anything else? what the best decision?
do you think that 6 cob in 2 rows of three would be effective in a 4'x4' and would it be comparable to a 600w HPS? I as because there are companies selling similar arrangements but with older type cobs. what would be the main difference/s between cxb3070 and cxb3590 cobs? Also I have noticed some supplement with other diodes like far red/blue and IR diodes. is that actually necessary? thanks and top notch channel btw
how much would you charge for a led that will cover a 5x5 really good. like 70+ watts a square foot. and a good average par? I am building my new grow room and am thinking of going with your led designs instead of hps
Hi, What would you recommend personally for cob build to out perform a 400w hps for a 1mx1m tent? Im in new zealand so we have 230v mains voltage. Im interested in efficiency without loss of performance over hps..
use a combo of 200-300w led and 70w hid, use white leds or a color combo, dont use just purple, plants like the whole light spectrum, led is very efficient, but hid is very good for plant because of the far reds and ir, but white leds also output IR so you are fine with plain cold white leds, also warm white is better for flowering stage, for veg cold white is best you can use only 400w led cob chips, if you buy a cheap grow led (chinese) please please see the reviews because they tend to show higher power in the description than it really is
I was looking to pick up a Mars Hydro light off their website. I called the number and I speak to to Chinese women who barely spoke English. The whole deal seemed sketchy so I didn't buy the light. Did you have the same issues when ordering?
+growmau5 Thanks for the reply. I have a 3'-2" x 1'-8" grow space/closet. What would you recommend for this space? I've been interested in building my own light but lack the experience and tools. Is there a kit available around the same price as the Mars light?
ok thx cause im just ordering the heatsinks only,as you remember few months back i order the 46 inch heatsink bars from heatsink usa and after watching ur side byside with the pins i went ahead and order the pin heat sinks.
great video M5 on your season 3 , you used far red leds, i just got my 4ft deep red led bars from BML. Can you tell me whats the difference between far red like yours and deep red is the one BML recomended for me? and also do the reds have to be on same time as the 3590 or just few hours of the flip cycle? Basically my set up consist of 12 cxb3590 one meanwell HLG 240h-c1750b per four cobs and 2 deep red BML led bar gonna be sitting between each of the cbx bar in a 4x4 space. The whole room is set up like that in a total 10x40 space.its been a couple months following ur page and its been a great help. thanks for all your help and knowledge. Also i remember you email me aout my power consumption with this set up in a 4x4 space,is their another setup config that can be used to save on power consumption but wont degrade lumens to much and will save me on power consumption? Thanks bro
+ShuhDonk Led life is determined by several factors, drive current, temperature etc. These kits are design to operate at 50 watts, well below their specifications of 130 watts so 100000 hours is totally reasonable under these operating conditions Cheers Mark
I don't get why people pay way more for diy , no infrared, no uvb and it's more expensive than pre-built plug n play. please check out PerfectSunLED, Neils killing it!
5w cips drivven at 2W? Seen this crap on Mars, Apollo and the rest of the "greatest shit from China". We will stick to quality COBs. May as well plug in Mars dude - at least they charge more reasonable price for their blurple boxes.
Balabajka what are cips drivven?I asked about uvb and infrared ray supplementation. I m researching myself, thats why I came to this site. but if I can learn anything, that's my goal. they say you can learn even from an idiot, if its only not how to be one.i haven't compared neils par #s with these here,but I will. I want only the best and to share it.peas
Ad A If the driver was integrated and powered by standard AC wall power, then it essentially becomes like a desk lamp. If you had 4 desk lamps in your office, would you wire them in series before plugging them into your wall?
Just checked the link is this for the 5 light setup that has the x with 4 outside lights and one center ? Thank u again growmau5 for all ur help just want to be sure I'm ordering the correct stuff
"+Josh MedLogics hmmm, same price as a mars, not really, that is a cheap light putting out maybe 1.7 µmol/J (or PAR per watt). these cxb3590 are putting out 2.7 µmol/J of plant usable photons. so you gotta spend the bux to get the efficiency. but 4 or 5 cobs in your space mounted in a S config, or staggered configuration would work quite nicely." Hi growmau5, at the first tanx for your videos, you re on busines with his kind of light but also help a lot diy grower...and thay s sound really generous from you!! Now, why did you raccomand an "s"configuration? Should not good a "cross" ike in this video? Finally i saw your test (pin Vs fim heatsink)...pin heatsin seem good, i know the datasheet and they are designed for low W light, less than 50w as you know but seem really good, 50 celsious is an unbelivelable performance! How do you think would be with a 1050mA cob VS an artic alpine cpu with fan? Many many thanx!! One love.
@growmau5 ,you should at least get back to your people emperor Mau ..lol 3 years no reply.. I subbed you in the last vid i watched ,but ffs man ..keep it real..
Hay bud i got 6 chip here in funt me i need a lay out for tham. I got a 4bay 4 tant. But i dont think it will be a nuff i got marz 700 a some cheepo 600 cree chip 3watt. Magnufiy led i can uses. To fill in spot. But how wood u lay tham out and u no how i am runing tham 240hlg dim 1700mah. Yah i no and one marz diver lol lol for the 2 chips its 6 citizen cluo48 6jan chips 3500k
I'm curious...can i but 16 3590 in a 1x1. i would use an phresh inlinefilter and send the heat direct out of my tent. what would happen? or lets say 12:D
Out of anyone in the grow cannabis community, this channel was my favorite. I frequently come back. It's a shame you disappeared.
I feel he would have more money from youtube over the money from the job.

Cool video thanks. I like the configuration, and I think it's gotta be much lighter than bar sinks.
I built one and its working out very well.
Why do you wire them in series? This divides the voltage by 5? Why not in parallel? So you get a driver at 36v that gives 600w and put a bunch of cobs on for example the Cree if you wanted to run them at 100w you could put 6 on one driver as when you wire in parallel you divide the watts.
cree rates that diode at 40% efficiency at 1.4 amps. factor in the driver and it drops to 36% efficiency. how are you coming up with 56% efficiency?
Could use a smaller pod in center
Yo Growmau, Do you get a advantage if using a lens vs a reflector? I would like to see a side by side lumens test at same drive current. Are there other advantages other than protecting the cob?

Nice Video! How hot is this thing/if my 3.2 feet tent is 25 degrees with a 220m³ exhaust air how hot is my tent going to get?
pls answer
how much dank yields can I get with this light in a 3x3 setup? thanks

Hmm could you illustrate how the pentagon frame would look like? Its hard for me to figure out how to frame it out with the rail lol.
growmau5 for the win!
can you do that same test with out the reflectors?
Or just that middle one. To lower that center hot spot
Hey brother! Given your experience with these COBSs, would you object to a 9 COB on a mover over a 4x4 area. Basically a slightly rectangle shaped fixture. Gonna have some cash on hand here pretty soon!
Thanks a lot for making this video!

Thanks again!
the links are down, what do you suggest in 2021 ?
Is there such a thing as a chart to compare higher current higher photons to lower current lower photons. And PAR values of each.
so couldnyou fit more cobs on a driver if the cobs were 24 volt instead of 36 volt cobs?amd if so how does that effect the light output amd effiency
Hi great video.i have a question if I use a Uv and a ir cob then used a 2700k a 3000k a 5000k 6000k cob would that cover full spectrum?
Do you know when these kits will be available from cutter again?
Hey growmau5 i know you barely have time to read all these comments, but if you notice this one, i've been wondering about you mentioning that CMH are 42% efficient at converting electricity into PAR light. I've been looking forever for more details about this, but i can't find anything online. Could you point me towards the right direction? Pretty please?
What's the par output with just one cob?
Are the two large cutter kits correct on the square footage?
are you going to be restocking anytime soon, says 0 stock on all your products
Hy. Great Job ;-) i´m planing a 6-COB light(36V/1400mA each) only for blooming and not sure which temp to choose? All in 2700K or 4x2700+2x3500 or anything else? what the best decision?
do you think that 6 cob in 2 rows of three would be effective in a 4'x4' and would it be comparable to a 600w HPS?

Also I have noticed some supplement with other diodes like far red/blue and IR diodes. is that actually necessary? thanks and top notch channel btw
NO????
I have a 3x3 I need this kit but I want the cobs running at 100watts each any kits outhere I want to run it with a glass lenses no reflectors?
So how’s this hold up 3 years later??
I also Like to know
how much would you charge for a led that will cover a 5x5 really good. like 70+ watts a square foot. and a good average par? I am building my new grow room and am thinking of going with your led designs instead of hps
Do i need the LGSU250-1400D, 250 watt Dimmable driver like in your 4 Cobs setup?
hey Growmau5 , my growspace is 1.5m by 1.5m . What way would you spread the cobs and how many of em?
what size driver should I use for a 6 cxb 3590 cobb build, as these are 80 watt cobbs, at what level do I drive too. Thank you
thoughts on growing a single plant in a 2x2' with 5 cxb3590s @ 1050ma in an X config? 1' apart?
Is it OK to hold them with only 2 hangers opposite to each other?
Does 1x clu 048 1212 enough for 1 plant?
Great video mate. Subbed. Just wondering how many 3590's you'd recommend for a 2'x3' space?
Could you give us a reading @36" when there's a highly reflective wall (tent) around it?
+growmau5 Thanks I see it now! That's a massive difference
getting 100w Cree cxb3590 3500k COB. timber grow lights
Hey growmau5 I like what I seeing I can't wait to see more . well from the DGC light them up.....
hurry on that 10cobb I just about got the funds, lol. seriously thanks for all the info and peace.
Hi, What would you recommend personally for cob build to out perform a 400w hps for a 1mx1m tent? Im in new zealand so we have 230v mains voltage.
Im interested in efficiency without loss of performance over hps..
use a combo of 200-300w led and 70w hid, use white leds or a color combo, dont use just purple, plants like the whole light spectrum, led is very efficient, but hid is very good for plant because of the far reds and ir, but white leds also output IR so you are fine with plain cold white leds, also warm white is better for flowering stage, for veg cold white is best
you can use only 400w led cob chips, if you buy a cheap grow led (chinese) please please see the reviews because they tend to show higher power in the description than it really is
I have 2 questions:
1. It is sufficient to 100cm x 100cm ?
2. What settings do you recommend?
I was looking to pick up a Mars Hydro light off their website. I called the number and I speak to to Chinese women who barely spoke English. The whole deal seemed sketchy so I didn't buy the light. Did you have the same issues when ordering?
+growmau5 Thanks for the reply. I have a 3'-2" x 1'-8" grow space/closet. What would you recommend for this space? I've been interested in building my own light but lack the experience and tools. Is there a kit available around the same price as the Mars light?
Using those white reflectors, there's nothing protecting the surface of the COB. What happens if bugs land on it?

Can this be build from wood??
growmau5 how many cxb3590's will i need for a very small grow box ex. a storage tote or maybe a slim cabinet grow box will 5 cxb3590's be to much
@growmau5
25w per square foot for cob
HallucinogenicHusky thanks
Hey Mau5 does the heatsinks comes with screws already or does it has to be purchase seperately?
+Son832
Hi Son, each heatsink in the kit comes complete with 8 screws to mount the COB holder and adapter and the side rails
Cheers
Mark
ok thx cause im just ordering the heatsinks only,as you remember few months back i order the 46 inch heatsink bars from heatsink usa and after watching ur side byside with the pins i went ahead and order the pin heat sinks.
once again bro ty for all ur knowledge and videos on these cobs and drivers, just got my 48inch deep red led bars in from BLM WOOT WOOT!!
great video M5 on your season 3 , you used far red leds, i just got my 4ft deep red led bars from BML. Can you tell me whats the difference between far red like yours and deep red is the one BML recomended for me? and also do the reds have to be on same time as the 3590 or just few hours of the flip cycle?
Basically my set up consist of 12 cxb3590 one meanwell HLG 240h-c1750b per four cobs and 2 deep red BML led bar gonna be sitting between each of the cbx bar in a 4x4 space. The whole room is set up like that in a total 10x40 space.its been a couple months following ur page and its been a great help.
thanks for all your help and knowledge.
Also i remember you email me aout my power consumption with this set up in a 4x4 space,is their another setup config that can be used to save on power consumption but wont degrade lumens to much and will save me on power consumption?
Thanks bro
will a 4 cobs on this config work for a 3x3?
is the whole cutte.au webiste down? the links aren't working for me
add www. to the beginning of the address after clicking the link. works for me that way.
Growmau5 please note to your viewers to NOT touch the cobs with anything. Slight pressure can damage it
I bought a cmh 315 - _-wasn't happy at all I did better with my 400w.. I should have bought this led kit with 6 clu48
what make/brand cmh did you get? they vary in price quite a lot, how much was yours? also, what brand of bulb, thanks bud
finally in stock
thnks
how long will a single cob last? Does the intensity lower over time?

Led life is determined by several factors, drive current, temperature etc. These kits are design to operate at 50 watts, well below their specifications of 130 watts so 100000 hours is totally reasonable under these operating conditions

how many WATS are though cobs 50 75 or 100 cause though numbers look kinda crapy

is there a place that you can buy a complete kit?
for the CXB3590 DIY whole kit ,pls help click,onepluslighting.en.alibaba.com ,whats app; 13632880686
I don't get why people pay way more for diy , no infrared, no uvb and it's more expensive than pre-built plug n play. please check out PerfectSunLED, Neils killing it!
5w cips drivven at 2W? Seen this crap on Mars, Apollo and the rest of the "greatest shit from China". We will stick to quality COBs. May as well plug in Mars dude - at least they charge more reasonable price for their blurple boxes.
Balabajka what are cips drivven?I asked about uvb and infrared ray supplementation. I m researching myself, thats why I came to this site. but if I can learn anything, that's my goal. they say you can learn even from an idiot, if its only not how to be one.i haven't compared neils par #s with these here,but I will. I want only the best and to share it.peas
Nice product do you do a uk version ???
+haribo stinky (Mr stink)
What would a UK version be?
Cheers
Mark
+haribo stinky (Mr stink) The drivers accept anywhere from 110-240V, the kit is universal, you just have to get your country's plug-end.

Where do you buy your aluminum?
we arfe the manufacture of making led heatsink ,whatsapp 8618257118760
Is this strong enough to grow tomatoes
xabc1 fuck yes
250w?
Could you use one of those "driverless cob led" which actually have the drivers integrated?
Can they be wired in series just the same?
Ad A If the driver was integrated and powered by standard AC wall power, then it essentially becomes like a desk lamp. If you had 4 desk lamps in your office, would you wire them in series before plugging them into your wall?

Link to buys not working any help anyone
let me google that for you. "cutter mau5" returned this result: www.cutter.com.au/proddetail.php?prod=cut2900
growmau5 thank u so much for the help with the link
Just checked the link is this for the 5 light setup that has the x with 4 outside lights and one center ? Thank u again growmau5 for all ur help just want to be sure I'm ordering the correct stuff
"+Josh MedLogics hmmm, same price as a mars, not really, that is a cheap light putting out maybe 1.7 µmol/J (or PAR per watt). these cxb3590 are putting out 2.7 µmol/J of plant usable photons. so you gotta spend the bux to get the efficiency. but 4 or 5 cobs in your space mounted in a S config, or staggered configuration would work quite nicely."
Hi growmau5, at the first tanx for your videos, you re on busines with his kind of light but also help a lot diy grower...and thay s sound really generous from you!! Now, why did you raccomand an "s"configuration? Should not good a "cross" ike in this video? Finally i saw your test (pin Vs fim heatsink)...pin heatsin seem good, i know the datasheet and they are designed for low W light, less than 50w as you know but seem really good, 50 celsious is an unbelivelable performance! How do you think would be with a 1050mA cob VS an artic alpine cpu with fan? Many many thanx!! One love.
mau5! please make me 2x4 flower unit buddy. spend hours watching ur channel man! \m/
nice!
damn 495.00 for tha cob hell i could save you 100.00zz
