Some viewers have found ep 1 (now called pt2/7) to be too advanced, assuming too much prior knowledge of LEDs and electronics. This is my attempt to define terms and take it a step back for those TRUE BEGINNERS. www.cutter.com.au

[@innerthought4012]

Wow people really complain for free knowledge these people need to research on thier own time...that's how we all learn before social media...bless you brother for taking time and sharing your experience

[@poloponix3602]

dude your a great teacher. so glad we have someone on our side teaching us things like this! Keep em comin!

[@Shadowboxe]

Who's still watching and learning from this in 2020-21 Great stuff, I'm slowly buying components, one by one and leading on the job, before I'm sure I've got all the right parts for efficient DIY lighting.

[@Skeptic2006]

What cobs are you buying atm?

[@grimthereeper]

Who said your prior DIY was too hard then they cannot follow simple directions. That shit was easy and self explanatory.

[@rayreeves4681]

You have a skill for teaching. Every new complicated hobby i get into i have to slowly absorb knowledge from forums and google so its nice to have the process of everything i need to know in one place.

[@TheFredkent]

Excellent explanation , and as someone who has always been slightly in the dark you have opened my eyes as to the actual simplicity of this process and given me the motivation to proceed to my next build, many thanks, you are a star in my eyes.

[@SAWMetalworks]

I don't know what the disclaimer was for you explained everything very well. Once I watch the heat sink video I feel comfortable designing and building my own light.

[@boringlyfactual6368]

Outstanding. Watched it twice. Learned a lot and enough to proceed with some confidence. Thanks.

[@andreimj]

Thank you so much. Nobody has ever had the patience to explain physics like this to me. 8 years and this video is still relevant

[@hepcat5199]

Excellent. I just built a 4 cob bar light that I got from GreenGenesGarden. I watched his build video about a 20 times and have also watched your tutorial vids for us uneducated and learned so much. So good of you guys to share your knowledge. Cheers.

[@tazblink]

Another great video. I would have to say the only real problem I had from the last video was understanding how to calculate heat watts for a specific cob at a specific current. I would say that reading the brake downs on each cob on the rollitup forums took me awhile to fully understand. I am not sure if any one elsa had that problem but it might help to show a brake down and walk them through each column. I just built a 300watt light and it is just amazing and I owe that all to you. Thank you very much for your generosity and expertise. I only found your channel a little over a month ago and I already have a light up and running. It would have taken months more of research to realize this cob light without this channel. Thanks again..

[@dirkdiggler5647]

By far and away the most detailed and well explained tutorial I've found on youtube regarding the basics of l.e.d's

[@davidbugden3746]

This is actually explained thoroughly. My electrical teacher didn't even go this deep into some of the basic things you were teaching.

[@williwonti]

I think I understood the other video, but I'll never know until I actually do something myself. I think a kit will actually benefit people like me who learn by doing. Your real word stand-ins for the theory were also a nice touch.

[@steveg4104]

I'm new to the led/cob diy and trying to soak up as much information as I can in hopes of building my own soon. your videos are definitely giving me a greater understanding of how it all works and I just wanted to say thanks. I'll definitely be watching and hopefully one day will have some helpful input to add myself. thanks again for your time and effort to help others who are interested in this.

[@cannabisgrowzone7924]

You nailed it mate. Nice work. I’m new to led and I understood a lot more now than 21:44 minutes ago

[@schweddyballz4206]

Four minutes in and you’re teaching more clearly than my some of my teachers. Every one who disliked your last video was just pulling your chain. Alright pressing play

[@vvijay7]

You are better than My School Physics Teacher. Great Video. Appreciate your efforts. Thanks a Lot.

[@yusufusayd3151]

I thought this video was excellently done! I didnt see the first video to know if this was a "revised" edit or if this was the original with a prelude. But, this is exactly what i was looking for. Most DIY basic videos here on youtube always either brush pass the technical understanding aspect (theory) of the subject or they jump straight into their "model" of the project, again, not touching the technical stuff. So, for those people looking for "just show me how to make one by the end" type of video..then this aint for you. But if you trying to understand the basics of the technology from a common man avergage joe point of view. then this is it. Great job bruh!!!!

[@CoolOldGeek]

Extremely helpful. It helped tie together some missing pieces of my electrical knowledge and changed some of my long-held misconceptions.

[@bubbasgame]

Just found your channel. I wish I saw this a year ago when I chose to dump HID lighting and switch to a poor quality yet expensive fixture. After seeing this I'm half tempted to turn some screws while voiding the "warranty" and just gut my fixture to add better chips and driver's. You have my attention and thank you!

[@NoahNobody]

Good job. This got me closer to doing my own LED build than anything I've seen or read before.

[@Soilfoodwebwarrior]

Thanks for these videos I appreciate it. Trying to save money and understand this vital component to growing indoors. This is the first vid I have seen from you, I learned a lot from migro you tube channel, now your are completing my training.

[@jacoblankford2907]

so much happier with my cob led vs store bought. smell and density is night and day different couldn't have done it without you growmau5

[@Bunkerbizznizz]

Great analogies used to help explain a daunting mini learning curve , I will most definitely bookmark this and come back to as a reference . Great stuff sir keep up the good work 💪👊😎

[@Bloodreign137]

This is the best beginners led guide! I actually feel like I've learned a lot from this. Thank you for all the time you spend helping us that are slower to understand haha love your content

[@HighDesertGarden]

You put a lot of time and thought into this video. Even though I already knew all the information, I watched it anyway because I was curious to see how you would explain it. Good job.

[@paologrisanti7865]

Even if I understood all from previous videos, going easy as you done make all better! My little kids can understand too, now! Thanks for your work and thanks for sharing!

[@BARBELLS-AND-BUDS]

I wouldn't have been able to explain it this well. when I was learning if I had seen this video it would have been so much easier for me. Great work!

[@TheLeontheking]

this is definetely one of the most informative and well structured, easy to understand videos i have seen so far!! very good job! had to take the time to write this comment, but now i obviously need to go to the next part of the series ;)

[@ThursdayMonkey475]

Holy shit. A like is just not enough. This video just helped me immensely. This was such a clear, concise, and educational watch. I will be referring back here when I start speccing out my light. Thanks a bunch, man.

[@joe1138gz]

Nice! Good to see you back. I must admit I had a little trouble following your first DIY go 'round but I muddled trough. This helps explain in detail a lot of the less clear points. I'm excited to get my own LED grow space going soon.

[@joe1138gz]

+growmau5 Keep the vids coming! I've enjoyed them all and I'm trying to absorb as much information/knowledge as I can. I'm just bummed that the Colorado cup seems to be at least temporarily dead. I was hoping to meet you and the guys from TheDudeGrows.

[@mrstrongable]

Deff a detailed explanation i under stood for the most part how drivers worked but watching this video help me better pick a driver for my future led build... thanks!

[@midwestmangos2452]

What more info do you need?

[@psiloatlantis1246]

This helps a TON... The detial really helps.

[@soultrap8554]

Great vid, thanks and cleared up a lot of half understood concepts for me. I'm in the process of reconfiguring a HLG260 to fit a small space and this has been really useful.

[@bpkop1387]

Thank you for this playlist!!! I have 3 8x cob LED panels that were prebuilt by some company. A handful of the LEDs have gone out on them. This is going to help me replace the LEDs hopefully!

[@iRuf12]

thanks for uploads growmau5 these and the chill and rapid products have convinced me to give led a serious go. nice 1

[@mrman3196]

Hey dude i really appreciate you making this vid. i know it takes time to make these but they sure do help us with the questions that we have thanks man!

[@Templeman420]

Just want to say thank you. I learned a few things and appreciate you sharing your knowledge. Thumbs up

[@markdavies8835]

Great video, first video I've found that even talks about drivers thank you

[@backwoodzbum]

I've watched 100s of hours of your vids...Man..major props.

[@drrdmohile]

Thanks for explaining the basics so well.

[@JC-ul4xl]

Great job explaining Krichoff's Voltage law , clever. As always making enjoyable videos. 😁

[@morg775]

thank you, you really put some effort in, and I love the explanations. thanks for taking the time. I'm doing an anjeet 1200 makeover soon so this helps me see what I'm working with and helps me determine what cobs I can run with my current drivers.

[@seanl1100]

The way u teach is perfect, anyone still behind never had a chance

[@tbublz]

Rofl I think it's perfect too. Very comfortable with his speed and explanation on things. Good compliment there!!

[@jacquesvandermerwe16]

Thx dude, thats all I needed to know. After watching 30+ videos, this is the first one I understand and that explains what I want to know

[@sgarcata]

Wow... I thought your other series was fantastic... but I'm sure this will be as well... thanks for your time and effort in teaching this. (Saroj in RIU)

[@honawikeepa5813]

Thanks for the video series. I hope to grow better buds in the near future. Cheers from New Zealand.

[@mrSnipeZA1ot]

Thanks for video man! Really explained a lot! Im thinking about building a grow light here soon and Im definitely gonna be using this video as reference!

[@Thezaneable]

30 seconds in and i knew you were worth the subscription. Great video!

[@Lbionic]

You are awesome. Thanks for sharing all your work and knowledge

[@ledbuilderdotorg2888]

Thank you Growmau5 - your videos are so helpful.

[@matttilley5669]

Excellent (and very much appreciated) tutorial...thanks so much!!!

[@Volound]

i was a complete noob to LEDs and electronics and watched your videos and made my first light, complete with resistors and voltage boosters. wasnt difficult.

[@DurzoBlunts]

awesome microgreens shout out. never thought of Cree COB for my greens. Awesome vid again Mau5.

[@JR-rk5dr]

i have a background in electronics... but honestly this is so well explain even an absolute newbie could get it. great job. i just wish my electrical engineering prof would explain staff like this lol.

[@HighdesertOgre]

Thank you so much for this video! you perfectly explained the questions I was having. you are a true gentleman for sharing your knowledge with us.

[@nickbigg84]

Good video very informative as you were explaining efficiency I realize you were talking about Ohm's law. Basically the higher the voltage you run the amperage will drop down automatically and the watts stay the same. Using higher voltage with anything is more efficient. And since you have to match LED voltage with driver output you're also spreading the load and the heat will be lower due to view material in between the LEDs.

[@MedicallyFit]

Ok I'm going to follow through this series!

[@1whoFartsinthewind]

Finally someone I can understand. Thank you. Are you planning to show a complete build?

[@theretrobandit]

This is a really well made video. Great job putting it together.

[@northendgaming3831]

I have been growing under lights I put together for just over a year now thanks to this video. Thank You Growmau5!

[@Skeptic2006]

How do you like them honestly? I'm thinking of investing on some but still a bit afraid the yields would suffer. Would be cool to see an updated version of this video. Best leds atm etc.

[@jarrodbrush]

@@Skeptic2006 Can't speak that they are the best, but I have been using the HLG QB132 boards, currently getting about 68w per board (4 boards) in a 3x3. Can get about 4oz per plant, 4 plants in 3g-5g fabric pots. I believe most reputable LEDs will do similar. I am considering a 2nd flower tent, and going with strips, but could end up in another direction.

[@Skeptic2006]

@@jarrodbrush If I'm going to do one it will be using Samsung 301B leds since they are the most efficient white leds out there currently. Buying it all at ones for a 1000w hps equivalent is still just too pricey for me. But I guess I could first build a veg light with just one driver and half of the strips.

[@shanestevens622]

@@jarrodbrush Hello there, I've never done this so just trying to get some info, so here goes....when buying leds do you just buy any ( I'm talking about whiteness, or light spectrum I guess) or do you have a mix of say , red or blue light, infra red etc.... leds? I haven't really looked into what's available yet just thought I'd ask someone who's done it successfully. Thanks.

[@jamesrandle1943]

Thanks for the logical and straightforward explanation

[@isaacweir6798]

Truly a great video.I appreciate very much this effort.

[@dustincurrie8797]

Hey man, I have a degree in electrical engineering. Nice work explaining voltage/current etc. Thanks for the video too, great practical stuff.

[@materra3]

Nicely done, was stuck in calculation for about a month. Your video solved my issues :)

[@dayalanmeyer3474]

lol never saw the 1st one but about to check this out was recommended by a friend to check your channel to start my research on possibly building my own...South africa

[@ckennedy109637]

Thanks so much man. Because of you I will make my own light one day soon !

[@williammorrow4977]

Well done... easy to follow! Great information-- Thanks for taking the time to share your knowledge

[@Beltanas]

YES. Thank you. I've been pouring through freaking videos all day long trying to figure out how to build my lights.

[@Max_Power_3.1415]

Just watched again prior to ordering my COBs and driver. Thanks yet again for being the Bill Nye of LED grows. #growersLove

[@DonPattenaudegrowdaddy]

Excellent video. Very easy to understand and well explained. Thank you much for your time and effort.

Great detalisation man. Very interesting to watch

[@Fozzybeard]

I could totally watch this. I haven't finished yet but I remember how complicated the previous video was, I ended up wasting some money on some premade junk

[@bmunoz441]

Great video. Led's for dummies like me. I will be doing my own build thanks to u. Cheers

[@mikemike5347]

This video definitely much more understandable. My only confusion was the driver. Thank again...

[@Yelnats101]

subbed. great info so far. easy to follow. I Will finish later. it's late lol And in process of ordering led build parts .

[@tedsmeds8136]

AWESOME breakdown thank you

Thanks you for your pacience and excepcional explanations. Greetings from Brasil!

[@tjwooten8095]

Great video thank you for all your information on the help would you please do a video just about the drivers like in complete how to pick one or two out for a setup or add links to your kits for building your own LED grow light

[@azteca088]

thanks, very detailed and great examples.

[@ilampaulino]

You'd make a great teacher. Thanks for sharing

[@Hirudin]

Loving your videos!

[@alexbatsakis8795]

Thank you so much I was very confused on if i could plug a driver into a standard US outlet.

[@djloud4498]

your vids are great. if people can't get it then they should do there own research ur doing a great job

[@rimo966]

excellent video... mad props!!!!

[@ilka1132]

oooohh my god thank you!!! this made so much more sense than anything ive ever seen

[@doubledigitdreams]

I've seen all your diy stuff and I've learned so much, thank you for taking the time. i would like to learn more about building with bridgelux leds specifically the vero 18 for a more budget friendly grow light, what are your thoughts on these leds.

[@Deeleeshush]

Thanks for breaking this down mau they were just words to me before 👍

[@senaizzet]

Im a electririan from the uk. I know I shouldnt need to watch the begginer vidieo. But that was great video.

[@billyrg08]

would you help me make those lights?
