200 Free Hempcrete blocks - eco building material

Hi all, is anyone interested in some free hempcrete blocks, amazing climate change busting/energy efficient building material? You can use them alongside a timber frame to make incredibly well insulated walls. We have almost 200 left over from a build we did and my plans to reuse them are not materialising so looking for a good home as they are currently sitting in our garden under a tarp. Collection from me near turnpike lane. DM me if you want details on dimensions etc.
