Devil in the details, milk jug edition

For those gardeners who make their own manure tea, the obvious thing to decant your 5-gallon pails into is old plastic milk jugs. They're free and easy to store, pour from, and cap off.

But.

Look closely at the jug. Is it made from two peices of plastic sealed together? Remember, your garage will get hot and the pressure inside the jug will rise. If there's a weakness in the seams anywhere, the liquid will find it. Half the jugs sprang leaks. This isn't a dry ice bomb class failure, fortunately. But it is a mess.

I'm trying some old injection-molded round gallon jugs--no seams.

FWIW, for homeschool science class I'd made a couple of robust screens of different mesh sizes to illustrate sorting by "particle size" in soil. They've been kicking around unused for a while, until I needed something for making the "tea."

I read blogs of some people who occasionally discuss their "prepping" for emergency needs, and it seems to be pretty common knowledge with them that the polyethylene jugs – such as gallon milk containers – are made with non-durable plastic that promotes biodegradability, Most have discovered this by storing purchased spring-water that came in such jugs, and later finding wet shelves under them.

I was wondering if the mix was corroding the plastic somehow, but didn't think to research that. I hadn't known it was a different plastic.
