I am using a Hovabator this year.. trouble is, I have not found any rubbermaid or sterilite tubs that fit into it; they are all either too tall or long. Now, I have a tub that would fit fine, but the lid is pathetic and not at all airtight or snug..
Here's my idea: to use this, with a plate of glass over it for a lid. Now here's where I need some advice: I was thinking of using Vaseline around the lid of the r-maid and then placing the glass atop it to avoid gaps and lost humidity. I got the idea from my friend, whose gas cap on her car leaked; she coated it with vaseline and it seals fine now..
Any ideas as to how this would work?
