That's what I'm thinking that I should get rid of the press n seal. They are 6 quart tubs from sterilite and the lid really doesn't seem like it is totally for lack of a better term sealed or air tight seems a bit loose when u put it on has a little play. So with this said I will prob. Remove it and just keep adding distilled water every few wks or so. To make sure it's humid in the tub. Thanks again
