A 2 month "buffer" (beyond that needed due to crop seasonality) needs to hold a lot of pee.
This processing time can be reduced to 10 hours by adding watermelon seeds[1], which contain the enzyme urease.
If only the Romans had known this! They stored large amounts of urine (converting to ammonia) for washing clothes. For this reason, Roman laundries were legally forbidden from being located within city limits.

- schiffern 4y agoThanks for correcting me. To add insult to injury, I even checked first to see if there was a rule about that! This really should be added to the Guidelines. It might avert some future embarrassment for others. I want to follow the rules. This was a discoverability failure (as your need to link to a third-party search tool as the "source" should demonstrate). Thanks again. https://news.ycombinator.com/newsguidelines.html https://news.ycombinator.com/newsguidelines.html
