Is the bathroom used? I mean for showers/baths where there would be steam. I wonder if you aren't using it, it might not be very humid at all. If you are using it, I'd think that would be more than enough.

I think I remember you using Home Assistant, do you have a humidity sensor?

Also warmer air holds more water, so cold areas may not hold much water even if the relative humidity is high. I seem to remember hot water cupboards being a good place to grow mushrooms for this reason.

Don’t have anything for humidity at the moment sadly.

It’s a combined shower, bath and toilet. So a fairly big room and only 1 kid showers in there once a day. It’s got a single skylight that probably lets some air through. We just use our ensuite.

Main problem is Oyster mushrooms require air flow for oxygen and reading level light, but not direct sunlight. So I can’t keep it in a dark enclosed space with no airflow, which would keep humidity up.

I would guess that one shower a day adds more to the humidity than a bath of cold water sitting there all day, but that's just a guess. However, it may help make the humidity more consistent.

I would be pretty sure it won't make it less humid, so give it a go and see if it helps.

The problem is I had it there while there was one shower a day and that's where it stalled. So fingers crossed the bath helps!

Good luck!
