1xCC-COCO-COBs

Well we got even more nugs forming up now, the plant is really packing on some weight and smells great. I’m thinking the plant is gonna be a great yielder. The nugs are starting to give off the same smell as the last plant I grew. It’s got a great chocolate cream mix that smells awesome! I’m excited to hit this treat again! 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
