Should San Francisco Build Hemp Houses?!

"Hemp can be made into any building material, including fiberboard, roofing, flooring, wallboard, caulking, cement, paint, paneling, particleboard, plaster, plywood, reinforced concrete, insulation, insulation panels, spray-on insulation, concrete pipes, bricks, and biodegradable plastic composites which are tougher than steel.

Foundations can be made out of hemp hurds, a processed based on ancient technology adapted for modern use. To do this, set up a plywood frame (preferably hemp plywood), then fill with a mixture of hemp hurd (wood chip-like substance) and combine with lime, sand, plaster, some cement, and enough water to dampen, and let the mixture set for a day. Then take the frame down, but let the mixture continue to harden for about a week. The lime and the hurds create a chemical reaction which binds the mixture together. Amazingly these structures continue to get harder and stronger everyday until they fossilize, as is testament by a 6th century hemp-reinforced bridge in France. After this happens, the hemp foundation walls are as strong as stone.

Hemp foundation walls are 7 times stronger than concrete foundations, half as light, and three times as elastic, which means that these building will bend, but not break. Because of their superior strength and flexibility, hemp foundations are resistant to stress-induced cracking and breaking. Even earthquakes and other natural disaster cannot break or crack these structures.

Hemp foundation homes and buildings are self-insulated, including thermal and sound insulation, resistant to rotting, rodents, insects, and they are fire proof, waterproof, weather resistant, and the walls breath so the rooms do not get stuffy. Hemp homes stay warm in the winter, and cool in the summer.

If hemp were legal in the United States, it would be the cheapest source of raw material for concrete-like foundations. Plus hemp hurds can be processed in existing wood mills without major changes to the equipment. Hemp-foundation homes are ecologically appropriate because they are inexpensive, and can be prepared on site using only a cement mixer, and the material would be cheap and abundant.

Cannabis: It's Not Just Medicine!

Germany and France are using hemp for construction material, replacing drywall and plywood. A French company has built over 250 homes using hemp materials. Hemp homes have also been built on the Pine Ridge Reservation in South Dakota. Using hemp is economically smart and ecologically appropriate, plus the homes built with hemp are as hard as stone and are not subject to natural disaster."

Imagine if hemp homes started popping up in San Francisco. Now consider highway pillars, overpasses, skyscrapers, and sidewalks?!

San Francisco wants to be green - and we demand sustainability: let's grow industrial hemp domestically to keep the cost down. This is a great alternative to current methods - which poison our environment and destroy our beloved city!

Hemp isn't marijuana - it's a cash crop.
