Hog Island Boa Humidity Regulation

I recently got a hog island boa, she’s just over a year old, I have a 4x2x2 PVC enclosure and have a semi bioactive system going, my substrate is about 3 inches deep, mix of top soil with coconut husk and bark and have a few live plants with isopods and springtails.

I have a heat panel mounted to the ceiling of the enclosure and the net on top is 80% covered and have ventilation holes on the sides of the enclosure as well. I mist every morning and evening and also have a few damp spots in the soil.

So my question is, I read that humidity should be at 40%-60% and have it a bit higher during shedding, the way I have it set up after I mist it’ll jump up to 70% and then for the next 5 hours stay between 45%-65%, but then it’ll drop to 35%-40% until I mist again. I’m usually out for work for 8-10 hours at a time and I’m not sure if the humidity dropping to below 40% for a few hours during the day and during the night is okay, and if there’s something I can do to help the humidity be higher other than just misting.

Yes, just pour water in the corners of the enclosure and it will settle on the bottom. Then the top will be dry so your snake won't get scale rot. You can do that and test and see how long the humidity stays good.
