I had a spawn jar where I didn't use all spawn. I found 2 shrooms. Should I just leave the jar cap open or slightly to get more oxygen in?

So I had a spawn jar where I didn't use all the spawn, and I found these 2 today. I'm going to harvest it since the veil broke. Guessing I could get more flushes, but should I just leave the jar cap open or sligthly ajar to get more oxygen in?
