> not a class-II vapor retarder No time to elaborate, but from what I've read about it, hempcrete houses were built in different environments, even on seashores, as the hemp will petrify and turn the lime back into stone, but keeping the good properties. I've yet to hear about problems with water vapor or about one where it's uncomfortable to live in. Hempcrete has superb insulation properties, it may easily be the best material for home construction. https://insidergrowth.com/advantages-and-disadvantages-of-hempcrete/ https://insidergrowth.com/advantages-and-disadvantages-of-he... https://greathemp.net/advantages-and-disadvantages-of-hempcrete/ https://greathemp.net/advantages-and-disadvantages-of-hempcr... https://www.nytimes.com/2018/01/29/science/hemp-homes-cannabis.html https://www.nytimes.com/2018/01/29/science/hemp-homes-cannab... > they all still use nylon brushes Or boar hair ... and that's obviously not good either. Don't know what the best material is. But with using just the nylon brushes, and replacing the rest with wood, we'd save apx. 98% of the material. > You must be unfamiliar with warehouse conditions I'm not. But if you eat plant based only, that's maybe less worry than if we were talking about meat/cheese, I assume. There were no individually packed deli/cheese cuts when I was young. The shops instead had a counter with a shop person preparing orders, packing them into waxed paper. I've seen some counters recently, so it's still practiced somewhere. And people buy it and live, even without plastic.
