RickCorey said:This is not a cheap solution unless you have 100s of trays or plan to invest for years of seed starting:

plastic food film ("Saran Wrap") comes in 18" and even 24" widths from food supply stores. One roll will cover thousands or maybe millions of trays.

Or you can laboriously tape pieces of 12" food film together to get a sufficiently humidity-tight cover.

Actually, if you have a Costco/Sam's club membership, you can get the plastic food wrap there pretty cheap, like $15 for like 5000 ft. I bought one from Costco back in '06 & I'm STILL using the same box!!
