2xGSC-COCO-COBs

Tutorial: Build & Assembly LED COB light See below commentary. Colas, colas and more colas...these ladies are putting in some damn fine work! 👌🏻 I know I’ve said this a fair amount during this grow but I am really impressed with the growth this week .. yet again these ladies have yet to let me down. It’s been an amazing journey with these two plants , the whole series so far has gone off without a hitch. I’ve really learned a lot from the community here at GD and put in a ridiculous amount of hours of my own research time plus a few grows under my belt and it’s really starting to show everything I’ve learned.. The smell of the garden is ripening and by that I mean it’s getting dank! I’m glad I got a 6” by 20” carbon filter to suck up all this smell and vent it directly outside. You can’t even tell I have 5 flowering plants in my basement.. until I open the tent at least haha. It’s really starting to smell lovely in my grow tent and this is what I look forward too each and every grow .. these final few weeks are the most interesting and rewarding! Did I mention flowering cannabis is my favourite smell!? These ladies are packing on the flowers and they’re swelling up day by day now. I continued to defoliate the bottom 1/3 of the plant to increase airflow around the buds and decrease any chance of humidity problems with how packed the garden is right now. I’m really impressed with the LiquidKoolBloom by GHE , I’ve found it does stack up weight pretty quick .. it’s a great bloom booster that’s pretty cheap too. As you can see in the photos and videos the plants are forming up that sea of cannabis and it’s starting to show what we might be able to expect from them come harvest time in a few weeks. The sight of all the colas everywhere formed across an even canopy looks pretty dope!! It will be even more exciting as this progresses further into flower ...! Constructing the ULTIMATE Light! Required Items: * 10 CXB3590 3500K * 10 Ideal Solderless Holder * 10 lenses or reflectors * 10 thermal pads or thermal paste * 10 heatsinks 120mm * 2 Meanwell driver HLG-240H-C1400B * 2 10K potentiometer  * 2 electrical connecters * 2 electrical grounded plugs * 16 gauge(1/16”) angled aluminum * 18 gauge solid core wire 30’ * Power drill * Drill bits - various * Chop saw or hack saw * Wrench / Ratchet * Measuring tape * Marker * Rope ratchet hangers * Wire nuts * Zip ties * Bolts * Nuts * Washers * Money, lots. *Note - All the electrical parts can be sourced from alibaba.com for a decent price or you can alternatively find pre-made DIY kits on EBay with a markup. I recommend sourcing the remaining items from a hardware store like Lowe’s or HomeDepot. You can also buy a prefabricated light like this from timbergrowlights.com but you will pay double to triple the price.* I highly recommend watching videos on YouTube by “LEDGardener” or “GrowMau5”. Their videos helped immensely with the project and if they somehow see this - I owe you guys one! Both of them have great instructional videos on the DIY process and core required knowledge. So last week we built the frame and this week we are going to complete phase two! Phase Two - The Electrical work 1. Place your COBs into the solderless holders , make sure the + and - line up properly. 2. Place thermal pads/paste on back of COBs. 3. Screw on the solderless holders to the Heatsink. 4. Measure the length between each COB on your frame and cut lengths of wire plus a few extra inches to give some slack. 5. Make a long Positive(+) lead from the first COB so you have something to attach to the driver later to power everything. 6. Connect the COBs together in a series power circuit. Which is essentially just one long wire with the connecting positive to negative alternating between COBs as you go down the line. 7. Wire 5 COBs together in a series and leave a long Negative(-) lead from the last COB to hook up to power later. 8. Repeat step 4/5/6 for the remaining 5 COBs. 9. Connect the Grounded Plugs to the input of the Meanwell drivers. Make sure it’s wired correctly. 10. Take your potentiometer and attach it to the Dim+ and Dim- leads. You want the adjustment knob to be facing you. Connect the positive wire to the middle lead , the negative wire to the left lead and the right lead you want left empty on the potentiometer. 11. Now that you have the drivers assembled and your COBs rough wired it’s time to put on the reflectors or Lenses. Screw these in place to enhance the light penetration and concentration. 12. Attach the fully assembled COBs to the frame. Try to get the 4 long Leads(2+ and 2-) heading in the same direction. 13. Take the the positive and negative lead from the first set of 5 COBs and attach to the Output wires from the driver. Make sure to attach positive to positive and negative to negative. 14. Repeat step 13 for the other 5 COBs. 15. Test it out ! Plug the first driver in to power and hopefully you followed these steps .. it should provide a intense blast of light! Repeat for the second driver. 16. Now you can zip tie down the wires securely to your frame so nothing comes loose by accident. 17. I bought heavy duty zip ties and attached 4 of them, one to each corner. 18. Attach the rope ratchet hangers to each corner zip tie and hang in desired area! 19. You now have the ultimate light for a 4x4 tent ! This is just as powerful as 1000w HPS at half the power while providing a Full spectrum to the plant. Next week I will go over the specifications and nerdy data points about cobs and the light we built. Wow! So now you should have a working light fixture and hopefully some great looking plants too. If you’ve followed along with this series at all .. we have covered a lot of subjects. We covered how to make the perfect Coco, plant training, building a water table, building an auto watering system , building an LED light frame plus how to wire/assemble an LED COB light! That’s over 7 tutorials I’ve packed into this grow so far.. we have a few weeks left .. what else can I come up with? Thanks for following along everybody and as always Happy Growing! -TheWeedMan
