Thank you all so much for your replies! I apologize for taking so long to get back to everyone - I'm not able to get on here as much as I'd like.
@mike - thank you for the heads up on the pine! There is a ton of pine grown in my area and it can be bought very inexpensively through the state forestry office...or university extension...can't remember exactly which one, but they're stupid cheap!
@Glen - thanks for the clarification on the BL thorns! And yes, unfortunately we have a large area of EAB in my state
. Although I've been reading a lot of people saying how the EAB only attacks the older trees, which could still leave ash as an option for coppicing? Not sure, but I'm definitely going to continue looking into it.
@Nadine - I've never heard of Hempcrete! But off-the-chart R values sounds just about as cool as "hempcrete"
. Thanks for the heads up on that - I'll definitely be looking into it:)
@ Daron - Best of luck to you as well!
