This week on the Hemp Show, we catch up with filmmaker Joel Caldwell and hempcrete builder Danny Desjarlais about the film "Green Buffalo."

Coming off of a win for the short documentary category at the Santa Barbara International Film Festival, "Green Buffalo" is making waves.

Caldwell shares his experience on making the film within the limitations of the short documentary medium and how he was able to capture the resilience of the Lower Sioux in the film.

"I had the light turned on as far as this massive solution," he says. "We can create carbon banks and live in healthier homes."

Desjarlais explains how his crew is addressing the local housing crisis by rebuilding their community — one hempcrete home at a time.

“I came into this as a conventional builder, trying to find the bad in hempcrete, and I keep getting proven wrong," says Desjarlais.
