Depends on the state/local laws. Two examples: Hawaii is cool with it and might reimburse installation of rain barrels, while Arkansas says it’s only okay to collect rain if you’re not going to drink it.

Is there a transcript available?

Interesting. It would be reasonable to assume fungal spores could spread at the same rate in a direction as trees. I’ve heard recently (last year-ish) about a study done in South America that found fungi lowered the exchange ratio of nitrogen for carbon from trees because there’s so much carbon currently being taken in by trees compared to constant level of nitrogen in soil.

I love how being a plant owner is a never ending battle against buying new plants and having space for them lol. Just added this to my wishlist, thank you for sharing ^^
