I had a spawn jar where I didn't use all the spawn, and I found 2 shrooms. Should I 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? #2 Shroomok: it's invitro grow 👍 In fact air filter on the lid enough for such small amount of spawn. You can open the jar from time to time or just don't close the lid tightly
