Poly-Propagator

A poly-propagator is an appropriate technology for multiplying plants that are most easily propagated under very humid conditions. Poly-propagators have a frame constructed with wire, bamboo, wood, or other supportive materials. Use what you have! The exterior of poly-propagators is made of clear plexiglass or polyethylene as you can see from these two examples. If you build it with polyethylene, use plastic with a thickness of 6-8 mil. The bottom few centimeters of the poly-propagator should be leak proof and able to hold the water needed to keep plant material moist. These structures provide constant moisture and maintain up to 95% humidity, increasing the propagation success of hardwood and semi-herbaceous cuttings.
