Nice going there... good job !!
What a coincident.... I also just recently completed a new "prison"... eerrr "place" for my neps too...
Yup, this kind of humidifier were mainly used for swiflets house and poultry farm but not sure if the external plastic enclosure can withstand constant sunlight as it's mainly designed to be used indoor or under a roof (to also enable mist to circulate). I actually consider using it but for the reasons stated above, I decided not to use this for my neps since I grow them outdoor under shadenet.
Anyway, always good to see someone putting time, effort and money to setup new growing places for their beloved neps...
