Abstract: A beehive system includes a main hive body with opposed, insulated side walls having access ports formed respectively therein. A vent assembly fits into an access port, and includes a valve case with an outer housing, a coaxial core portion, and plural opposed panels between the outer housing and the core portion, with openings formed between the panels. A pivotally movable valve member includes a core portion and two or more blades attached to and extending outwardly from the core portion. The valve member cooperates with the valve case to regulate air flow through the vent assembly. A bimetallic coil interconnects the valve case and the valve member, and a perforated screen cover is attached to the valve case to allow air flow therethrough. A kit of components usable to retrofit an existing hive, and a method of retrofitting an existing beehive to add a vent thereto, are also disclosed.

Abstract: A latchably closable horticultural capsule is configured to contain a growing medium, and to be temporarily closed around a branch section of a parent plant during an air-layering propagation process. The capsule includes a first shell portion and a second shell portion pivotally joined together by a central hinge. The first shell portion includes a main shell body having a cup-like shape configured to partially surround the branch section, the main shell body having opposed end walls with notches formed therein. The first shell portion also includes two seal-receiving cups externally attached to the end walls of the main shell body. The seal-receiving cups have hollow notches formed in respective edge portions thereof, and are also configured to partially surround the branch section. The notches of the seal-receiving cups are substantially linearly aligned with one another, and also with the notches of the main shell body.
