Question regarding High humidity in home made incubator

[Dementeddogz]

I have the temps right and they stay fairly stable. Substrate is not overly damp, its more on the dry side, and expected it to stay around 50 for the time being and hadnt planned on bringing it up much more then that.

I checked on it not too long ago and was climbing fast hit 85-90 at one point according to hydrometer. Theres no water in the unit, and its air tight. Its a converted wine fridge. Its been gutted and is being used as just a box the only components being used are the fridges upper fan (displays also work but arent accurate)



Any ideas on what can be done to lower humidity on a permanent basis, dont want to sit around opening the door up when it gets too high or start drilling holes in it


Other then that its been working great. Switching over the heating source and thermostat, installing wire shelves and adding another fan, will have steady temps throughout. I have a glass shelf between the heat source now, acting as a divider, since theres only one large clutch in there now.

Any ideas would be appreciated.

Only real way is to increase ventilation in the fridge. Either add a few holes with a grill style vent control plate (to fine tune venting), or increase the fridge fan speed somehow. The other options are not really practical, but you could place a large desiccant bag in the enclosure, or one of those DampRid tubes. Those wouldn't last all that long with the constant moisture however.

I actually ended up taking care of it.I was trying to avoid putting holes in the unit but I upgraded one fan, had to rebalance heating though, and put in an exhaust vent that can open/close based on humidity levels if needed. Temps and humidity levels are holding constant as of now.
