raising humidity

[k12357]

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.
