Another thing to consider if you have a more powerful efficient light you can grow autos with less time because it's all about the dli daily light intake. I think it's called which is how much light the plant needs they can only absorb so much light without additional co2. I've grown photos and autos together and do the autos on 12 for part of the grow. You need to figure out how much light you need. And only give that even if that means running light closer on 50 percent. The leds can be closer than hps. But honestly if your space is cold you might want the extra heat.
