When you make a series of videos that contain like literally all the information you need and they're still super relevant and helpful 5 years later, my guy, you have done well. Thank you so much for sharing your knowledge and research.
Very good video bro . I Just did that exact setup . No college or any book smarts but I managed to figure out how to do these cob builds . I have spent countless days staring at my phone on the internet. I relied on the smart folks like you that have allready figured it all out . I'll use your video from now on when I explain it to friends. Very well put together and excellent explaining skills . Thank you !
Jeez man, rocking the house over here. Thanks for all your hard work. I know how much it takes to make an educational video. Props and keep on growing. Much love from the DGC!
I'm hella glad I came across your channel! This series is exactly what I needed. The way you describe, teach shit is perfect for my learning style. Yea I may have to watch these videos a handful of times to fully grasp all the knowledge, however you had my complete attention, 100%. That's saying a lot for someone like me that has mild adhd. Thanks for uploading!
Excellent intro video on the subject. To the point, stays on subject, provides lots of info without going into extreme details. which would confuse the issue. Moving on to the next one. Thanks.
thank you so much for taking the time to educate and share this sort of valuable information with the community! much love to you brother. im deciding on new lights for a 4x4 space i have and im so close to pulling the trigger on $2400 BML 1200 LEDs ... but seeing this sort of information (although ive never built a thing in my life) it really motivates me to take a deeper look into DIY. so thanks again so much
Hey Zahid, I shot this video a few years ago, so I haven't really monitored comments. Your comment really made me feel good this morning, sincerest thank you!
This is awesome!!! I was planning my new grow in a 4x4 tent and I was going to go with a 1000hps. But now I'm definitely going to build my own led light! I wasn't looking forward to fighting all that heat so this is a great alternative.
Thank you for being gracious enough to provide such elaboration explanation. Creating a vid to meet users specific space size is awesome. Thanx.Looking forward to more teaching/illustrations.
amazing stuff man just watched it a second time and it really helps intake all the info, im going to make a LED panel with some Cree COBs as well as smaller, color'd diodes to help spike colors that up the PAR for my 2x4 grow tent
Great video! I have some electronics experience from many years ago (back when we did our soldering with an iron poker heated in a buffalo dung fire) but I really needed to refresh my knowledge before trying a DIY COB light. This video was perfect for me. Thanks!
Great info! I really needed this, thanks so much. I've decided to go for a Nichia 108 with the meanwell PLM 40-1050, I'm going for a modular build so if anything fails the other lights keep working. Really cannot thank you enough for this info!
Thanks man, I've finished my first build, little clone light from cree xpe's and I'm stoked. Props to you man and best luck for your future led endevours. You got a follower here in NZ
Hell yeah man ...thanks a ton this was an awesome video and we can go back and re watch it ten times til we get it ...this is one them videos that's priceless man ...thanks .your the one that has gotten me wanting to. Build my own and I'm going to here soon ...I've been watching a lot videos about diy trying to learn all I can before I attempt it ...but having videos like this to go back too and is so valuable
GREAT information, I could have used it a month ago. I got some help from a local laser producer and he showed me the ropes on how to do an LED install. Funny thing is every time I had a question, his answer was " Ohms Law" LOL it took me a while to get it but yea. I will be reviewing this video again, firkin great breakdown.
Thanks for sharing, I have been wanting to go with LED for some time but don't want to just pay out the butt for fixtures I am not sure will perform as advertised. I am going to go through and build enough lights to cover an 8'x10' area to really see for myself if I can get good results from them. Thanks for all the DIY info so I can do this in the most cost effective manner.
Love it man. I have to admit I was yelling at you about thermal runaway until you mentioned resisters, lol. I was yelling about resisters and fuses and circuit breakers, lol. I'm a LED noob but have a solid background, expect questions from myself and probably my son as well. Keep makin the vids man. PEACE and keep growin, I know I will.
Dude your a pretty sweet cat, thank you for sharing your information I am in the process of building a pc grow box to challenge myself and I was looking at kits to buy and then I seen this video you’ve inspired me to try to build my own , I will be watching all of the ones you put out. Thanks for taking the time to do this
Great explanation!!! With all things being equal; P=IV (or any derivation of the formula).... Most folks don't feel like doing the basic math, but your explanation is perfect if people just put in a couple extra minutes and throw their numbers into a calculator (if so inclined). Thanks for the knowledge!!!
Bro I know you probably make a buck off of viewership and whatnot, but I really want to give you some props for putting so much effort into informing people like me. I should also mention that the new "first video" did actually help me understand what I'm sure would have seemed a much more heady video had I watched this first instead. Thanks.
volts x amps = watts its been 50 years since I had learned this in boy scouts merit badge. Thank you for bringing its forward for please keep this great way to cob led's
Thanks so much for this...sub'ed. I've got a technically slanted mind but have never forayed into electricity due to fear. You explain this very concisely and I'll be watching this a few times to make sure I get it. Thank you again!
I keep having to rewind to try and remember a lot within this video! Amazing job at breaking it down Barney style as much as you could. Update on new tech? Make sure you have a paper and pen because there’s a lot of great knowledge here
Hey dude loving that your back doing the videos again. I would love to see a cost effective way and the most efficient way to do a 4x4 or 5x5 tent. along with how to wire multiple driver to run off one plug and to have a potentiometer in there .
great stuff! keep them coming. I am going to be doing the ledwizard build from reddit using those cheap 100w cobs. His way is voltage regulated driving 2 cobs in parallel with the resistor as you mentioned . You guys who have the knowledge and the willingness to share is awesome!
these videos are very knowledgeableand helpfull , thanks for your time , also im looking to get me some leds and i get to say ,that all get what ever you recommend .
thank a mill...they seem identical because they both say they constant current. however the one you linked is the one...glad i waited for your guidance...phew!
When running parallel, you can utilize a "crowbar" overvoltage protection. When the circuit sees a jump in voltage it shorts the cobs out of the circuit. As long as the switch (mosfet, igbt) can handle the full current of the supply, the remaining cobs would be protected. Parallel is not ideal for constant current sources, but it something that can easily be implemented into an existing array. Also, depending on how complex you want to get, a crowbar can trigger the driver to shut down as well, sound alarms, etc.
Thanks I really enjoy these videos. I am looking into building a Space Bucket tote with two 27 gal totes and a custom spacer. should end up about 2x2 or 2x3.
hello and thank you for your way over my head but close enough to educate me demonstration. this is actually what i was looking for. a video i can watch over and over and grow along with. i want to build a 4 shelf rack to start my vegetable seeds on but i want to do it with the best possible tech i can find. i also want to eventually power it with a solar panel, i know what a complicated way to waste sunlight right? first how can i make a simple led grow light to light a one foot by four foot shelf for growing tomato plants? and what would be my cost estimate in materials for such a project? any light you can shed on this would be much appreciated. thank you.
I know i would love to see a component selection video for 2'x2' room. I've ran a total of one grow (lol) with cfls and it went beyond my expectations. I'm very much so a diy'er and want to step foot into the led world. Love your videos keep em coming!
+growmau5 What's up dude. Thanks so much for doing these vids!!! I have watched this DIY series twice while taking notes,looked though all of your comments, and joined RIU. I have a similar grow space as SirEenis gib except mine is 24" X 30". I have been wondering about size for a passive heat sink. It is recommended to go 5.88 x 38. Obviously this will not fit in my space. You recommended a "big chunk" to SirEenis gib. Can you help me figure the right size? What do you think about (8) cxb3590 3500k, CD bin 36v version run on 2 meanwell hlg185h-c1400 drivers in this space? I have the money set aside for a LEC315 and I'm excited to see if I can build my own that would match or exceed it's output. Thanks again!
thanks this video has my foot in the door. I am a straight noob and am starting from scratch and am hoping to have a well rounded knowledge of building LED's and matching parts with ease so with in a year I can design my own lights. I also need to get familiar with the extrusions and the bolts you use and do I cut the extrusions my self to size? Thanks,
Great video, I a interested in the mirroring you mentioned. Also I ad lots of others are running a 2x4 tent is a closet or somewhere tucked in a corner. What would be a good cob layout in that? Thanks for the video great stuff
hey growmau5 appreciate your videos it has helped explain the resson why some would go with diy leds. I'm wondering if you can help explain more on doing a setup for a 4x4 tent
wow this channel has the best info but could you do videos that are small where you could walk thru a single rail ... i could attempt one or two or if i was comfortable build 20 i just wanna get my confidence up on this before making 20 cob setups kinda like the flower initiative light you did , thanks for all ur work!
Hey man. I'm looking to build a light for a black orchid Geno box of size 50x100x50cm. Looking to create something like a T5 setup across the top but with LEDs of course. There's not much height in the tent so would need to be a low profile, Max efficiency, low heat, par output of maybe 400 just for keeping cacti and succulents compact over winter. Would love to hear your thoughts. I'm new to building but I used to build drones back in the day so have a decent enough knowledge to work from. Is it possible to do this stuff without soldering? Sick of that stuff after building drones as you can imagine ha.
so thankful ! can u please do a vid for covering two 4x4 trays (4x8) i want to run 8 cxb3070s from plc's bins... off two drivers.? is that enough light?
Dude you Rock!👍👍 Loved the video! And the build!👌 Man id like to see mybe something for a 4'×4' print I think it be easier to build more or less from there. Dude your my favorite on the tube for now.. Keep up the goodwork 👍 👊 👌 👍 ✌
I am working on doing vertical grow towers and have not been able to find a light good for that. Especially LED(the ole school hanging HPS aside) Now I can make my own custom corn cob style kine LED where I can set 3 channels, One for bottom light on when I have the seedling in the center, one for back half light on,(for when the system is closed in the circle configuration) or for just front half on, for when I'm running the system open configuration. (like I am not due to space restrictions)
Thanks for the great videos. I would like to know something about distance and discreet diode spacing in relation to how close you can hang lights to the canopy. If you have a light that is say 500w and you hang it 3 ft above the canopy to get a specific spread of the light, say a 4' x4' coverage, and you have an average par of some given # at that height could you take those same diodes and spread them over say a 4' x 4' space and lowered them to say about 8" over the canopy would/could you achieve the same par but have a more uniform coverage of the space. I am using par , could be photon but the basic question remains. Is this a good idea to pursue?
Bro , i really appreciate your video!!!! i learned alot !! currently i am trying to build DIY grow light for my fish farm to grow ALGAE .....THANK YOU THANK YOU!!!
I understand but I want to hook up to a 12v solar 145w set up. I can add more when I can. I want to keep plants going to keep strains through winter. don't care if produce much fruit. but keeping through winter with some growth to get clones early
I have a 7'x 6' room and a 12' x 7' room that I am turning in to a grow space. I have been slowly purchasing my LED panels but I want to make my own. What type of panel would work best and how many? I am having a hard time finding panels that have more that just red and blue so I mix with T8s. One of my panels that have all the colors is blown out and it cost 500.00 each. I am trying to understand how this stuff works so I can fix it. When I opened the panel up all the identifying numbers were scratched off :(
what up!! nice channel! im also interested in a 4x4 setup tutorial for noobz.. I would like to know what parts are needed and where can you find them. also can you explain how many lumens does a 400w or a 600w HPS PUTS OUT verse the DIY setup you talk about... stay green!
Just found your videos, most helpful info I have found so far! I have a quick question. If you are still around. I'm interested in using cobs, ir, uv, also some colors. Difficult?
