How do u make these cool diagrams!! U missed your calling brother!Also, be safe when measuring the current.
Set your space up first. Power disconnected. Then, after power is disconnected, hook up your multimeter to the cct so it doesn't move around even if bumped lightly, its best if you can plug the 2 ends of the open cct directly into the multimeter, or use alligator clamps. Then after you have your multimeter in series rotate your multimeter dial to the 10A position (make sure the multimeter probe is in the 10A hole, or the end of the cct goes in the 10A hole), and then finally power your cct, or plug the driver in.
Here's a quick example of measuring current.
3v battery pack "+" goes through multimeter, then through 1kΩ POT, then through red LED, and then back to battery pack "-." You can see here where I've broken the cct or opened the loop, and the 2 leads lay dangling to the left of multimeter. They have duct tape on them so when I insert them into the multimeter holes they make a solid connection and stay in place. With low power its not such a big deal but if this were a 600h(?) then ya it matters. Just safer.

I only measured the current of a small battery pack, so my max current selection on the multimeter was 200mA, if I were measuring over 200mA+ then I'd have to switch the hole where the red positive wire is in this pic below to the 10A hole on the far right instead of in the middle, and then Id rotate the dial to the 10A position.

My grow is at a friends nearby so sometimes I get a chance to hangout and do experiments or tests on the environment. But its hard because after I make the changes I leave.
I took both driverrs out of the tent and turned up the intake 4" hydrofarm with makeup ambient air.
The 4 " hydrofarm with the carbon filter is on 24 7 becaise of smell. I have it vented out thw only exit from the basement. Naturally the dryer vent.
U can see wherre AC would be a problem in a basement. So I am trying to run this as long as possible without adding an AC.
Temps max reached 84.
I know if i keep it up its gonna affect yoeld and maybe hermie the whole lot of em.
Been there, met Herm. I didnt like him hahaha
