Just one? Is the spread that good?

One QB 96 flowers a 2x2 quite well. Another option is wire two QB 96’s which would be around 90w per board. This would allow you to hang one on either side with the CMH in the middle.

That would give about 42w per sq ft which is perfect for a LED/CMH combo.

You have the option to use a HLG-320H-54A driver and dimming it down in case you ever move to a larger space or end up replacing your CMH. You could potentially replace the CMH with a 3rd QB 96 on its own 185H driver down the road for a total of 500w of LED.

I’m looking for a little advice on lighting. I’ve been using a 315w cmh (vertical Philips 3100k) for the last four years in a 3x3 with great success.

I’m expanding slightly, to a 3x4 area, and want to add some additional lighting to maximize my space. My budget is around $300 and I want to use LEDs.

I’ve come up with two options that appeal to me and am open to other options from experienced growers.

Option 1: move the cmh to the center of the 3x4 and run two 65w, one on each side of the cmh. (https://chilledgrowlights.com/our-p...t-x1-mini-65w-led-grow-light-commercial-grade

Option 2: run the cmh next to a single 200w led attempting even spread across the entire area. (https://rapidled.com/products/chilled-logic-2-x-2-led-grow-kit)

Option 3: you tell me

Attached are some photos of my typical grow style in a 3x3 with a 315w

Gonna have hot spots with a 315 and LEDs unless you can figure out proper light distribution. I used 1 315 3100 k along with a pair of China made knockoff boards in a 4x4 and was constantly having to rotate my plants. Granted I'm a newb so maybe I didn't know what I was doing. I would think strips would be the best way to achieve the best coverage.
