Ground to canopy gaseous media delivery system for crops including leak detection and hook and wand features

An agricultural gas delivery system for delivering at least CO2 gas to a plant of the type having a trunk and foliage, comprising:

• a. a gas supply adapted to be disposed proximate the bottom of a plant;
• b. a flexible tube connected to the gas supply at a node, the flexible tube having a lumen for communication of gas from the gas supply, the flexible tube being adapted to be oriented vertically along the vertical length of the plant, the flexible tube having a predetermined length that permits wrapping around the trunk of the plant and to extend automatically if the plant trunk increases in length or width;
• and
• c. a rigid tube connected to the flexible tube, the rigid tube having a lumen for communication of gas from the flexible tube, and at least one gas emitter for release of gas from the rigid tube lumen to the exterior environment, the rigid tube being adapted to be oriented vertically along the vertical length of the plant, above the flexible tube, the rigid tube being substantially straight to permit extension into the foliage of the plant above the flexible tube and the trunk of the plant.
