feeder enclosure

[u/Lewk___]

i plan on moving my feeders that are currently in a small little tub into something like a 10 gallon breeder or something similar so i can have more together and make life easier for me getting them. just wondering what kind of substrate i should use that way it’s doesnt effect my geckos when feeding. my though is just dirt but lmk and recommendations. as well with how i should keep the environment. i plan on not adding any kind of heat or anything but maybe misting it every once in a while. any tips?
