Dramas aside, the Quantum Board 324s are doing well. As mentioned in another thread, I like the spectrum of the Nichia NT2L757GRT-V1 mixed 3000K 80CRI and 90CRI leds, which was the main reason for choosing these over the QB288 or QB304 boards.
We are growing out some Paradise Seeds Wappa side-by-side with six 600w HPS bulbs (Gavitas). The HPS usually yield about 20oz per 7-8 week harvest. That's pretty average, as they've been as high as 24oz.
There are four QB324s in the room now. Each plant station has two boards with heatsinks that have been mounted to some L-shape aluminium (50mm x25mm x3mm) and are being driven in series by a HLG-480H-C2100A driver at about 200W per board, or 400W total per station. Each 400W frame has replaced a single 600w HPS. All the plants are being fed run-to-waste coco.
Here are the plants and QB324s when they first went in two weeks ago:
Here is the entire room they are in:
This is obviously a commercial operation. Those 600s produce a lot of heat.
