Looking for some more advice
I am putting together a 3x3 QB132 array for my 4'x4' tent. So far I have one row done and currently running, and those three boards are powered by an HLG-240H-C1750A. They're pretty bright, and I plan to run them at less than max output to get some more efficiency... but I'd like the ability to crank them to their max 2000ma current if I have good reason to do so. Would it be safe to run the remaining two rows on an HLG-240G-C2100A (1 driver for each 3 boards)? I imagine I'd just need to keep the internal pot turned down a little below max and confirm with a multimeter that the current is <= 2000ma. Do I have that right?
I like the idea of having 3 rows of lights that can be dimmed, raised, and lowered separately -- it's a compromise between one giant fixture and tons of individually adjustable lights. I like to grow a variety of plants at once, so having the ability to put the short plants on one side and tall ones on the other is pretty attractive.
Here's some stuff I learned since my last post. Hope it helps someone!
- Making an aluminum frame is much easier if you use rivets instead of self-tapping screws. I just clamped the pieces together, drilled 4mm holes for everything, and riveted the corners with 4mm aluminum rivets.
- A "center punch" really helps you drill your holes where you intended to. I tried a few different types of bits before I got a center punch and they all wandered a bit before digging in.
