KRATKY METHOD HYDROPONICS E2 MASON JAR GROW

Описание: Professor Kratky of Hawaii introduced me to passive hydroponics, which he called non-circulating hydroponics in most of his research. I like to teach principles of the Kratky Method for beginners, as well as seasoned growers. It is one of the best hydroponic methods for beginners. This DIY project is demonstrated, along with tips for starting and growing tomatoes. This DIY hydroponic method can easily be adapted to hot peppers, lettuce, house plants, and flowers.

Anyone who enjoys a container garden for plants, house plants, propagating, or cloning. Will easily pick up on this hydroponic method.

If interested in reading more about Dr. Kratky, check out this link to one of his research papers.

Wikipedia Says,
"Plants are placed in net cups filled with an inert growth medium such as rock wool, expanded clay aggregate, or coconut coir. The net cups are suspended above a reservoir of water containing essential nutrients in solution. Only the root tips are allowed to touch the surface of the reservoir. As the plant grows and depletes the water level, a gap of moist air will form and expand between the water surface and the base of the plant. The roots in this gap become laterally branching "oxygen roots," and absorb oxygen from the air inside the container.[3] By the time the water level is fully depleted, the plant should be ready to harvest. Thus, in one growing cycle, no additional replenishment of water or nutrients is needed beyond the initial application.

The method is named after Bernard Kratky, a researcher at the University of Hawaii who first proposed the method in the journal Acta Horticulturae in 2009.[1] In the article, Kratky discusses using floating pallets for commercial food production. Multiple plants are placed in net pots on boards that float atop a shared reservoir, with support beams slightly underneath the water level. As water is depleted, the boards eventually come to rest on the support beams, providing an air gap to allow oxygen intake.[1] The Kratky method has also found popularity among home growers, and is often carried out on smaller scales in containers such as buckets and mason jars. The technique is designed for leafy vegetables that do not consume large amounts of water, so the water supply does not need to be continually replenished."
