Event Description

Don't miss this intensive 4-day hempcrete workshop with Jayeson Hendrysan. Why build with hemp?

Hemp is an efficiently renewable annual crop, growing in about 90 to 120 days to yield 4-6 tons of carbon sequestering bio-mass per acre.  The carbon that is locked up in the plant offsets that which is released by heating the lime, the other main ingredient used to make hempcrete. Lime, like cement, is calcined to drive off Co2.  Then, as a powder, it can be reconstituted, cast, and molded.  It sets up by taking back the molecules that were driven off in the heating. Cement is heated high enough to make a solid set that will not deteriorate under water.  Lime, on the other hand is fired to a temperature that encourages a slower set, curing over a long period of time—50-100 years!   As it cures, the lime continues to pull carbon from the atmosphere in a process of calcification, thus leaving a micro-porous, incredible insulative, limestone home.
