I am using a clear plastic tub, with hole son all six sides. i have a 3 1/2 inch layer of perlite on the bottom with my cakes sitting on a small piece of tinfoil. my relative humidity has only reached 57%. why is my humidity so low? when the the rr lets grow mushroom video says that it should maintain itself? and how should i raise the humidity?
Try using a spray bottle and wetting down the sides of the container. Just try not to get any water on ur cakes. Hope this helps :)
Your holes may be to big or not enough polyfil in the holes.
You can always start plugging the holes until the proper RH is acheived.
