so im losing a lot of humidity from my egg boxes, i use a ralph davis style plastic tub with a sheet of plastic across the top under the lid, i did the same last year and it worked great, but this year i have two egg boxes both losing humidity and in fact i coulndt seem to get it over 85% from the start! im using the same vermiculite as last year! and i open the tubs once every other day to vent them, any ideas why its doing this!!!
thanks
