    Bobby can I drive a constant current buck driver like the Mean Well LDD-700HW off of a constant voltage HLG-185H-24 ?

    I'm looking for a way to add a 700 ma constant current string of deep reds\UVAs to supplement a couple of Samsung strips without using a second HLG driver as the buck driver is a lot cheaper.

    If that works can I run the deep reds\UVA string in parallel to the Samsung strips or do I have to run them in series ?

    We were in the same place as you back in 1986. I recommend getting the wood chips out of there before adding coolant. Most materials don't expand when contacted by the coolant, wood does, and it can get into small spaces. I'm not saying drilling a couple 1/8" holes will hurt but not a good idea on a large scale. The rule of thumb in steel when using a high speed steel drill is the chips should never be turning color as the come off the bit, if so you are turning at too high an rpm, alum there is no color change, hard to go too fast. We don't machine any wood in our cnc's. There is also a soft plastic material you can buy to test your programs, made just for that, or just machine "air" you can get a pretty good idea if things look ok. Also using the feed override to slow down helps when proving the prog.

    You'll be really happy just clamping a part and having all the work done, fast and accurately.

    thanks man. its been a lot of work to get where im at. the clones going into this space have stalled out and im getting a little frustrated. got backups on the way in case these tank. gonna dim my COBs down. i think they are too strong and they went into shock. this run will tell me for sure if im gonna build more COBs or buy a few DE fixtures to run at like 750w since i dont have high ceilings. currently about to test out this new square wave DE fixture and see how it does. im also trying to get a hold of their premade LED fixture and see how it does. i still think for the money a DIY cob array will perform quite well and you wont be spending money on bulbs anymore.

    i think thats what i did iirc. snagged a 30 pack of 3-3500k cant remember and did one per sqft at about 37.5w each i think. going off memory. works great for flowering but its one heavy sumbitch and heatsinks get pricey at 1 per sqft lol.

    they'll grow some donkey dicks for sure :) dont mind the circle, was trying to show someone a certain plant

    If you cant dim them down enough try getting some LED floodlights and take the reflectors off. I find that the transition from these to COB's, my case QB's to be better.
