1) It's not much. Maybe a handful.
2) There isn't much because it likes to die off on me. I don't know if you want a super-delicate strain of hornwort.
3) I'll be visiting Pacific on October 14th, and I work in the Bronx on Wednesdays, but am otherwise nowhere near NYC.
Let me know if you still want some despite all this, and I'll try to work something out.
