Abstract: A CO2 generation and control system for controlling ambient gas CO2 concentrations in a controlled environment agriculture facility, including a housing, a controller disposed within said housing, a CO2 gas supply electronically coupled to said controller so as to receive control signals from said controller; wherein said controller includes a plurality of data ports for connection to one or more environmental condition sensors, and further includes software, which when executed receives and responds to signals from said one or more data ports and adjusts gas output from said gas supply in response thereto, the adjustments being infinitely adjustable between no gas output to high gas output.

Abstract: A double-walled nested plant pot assembly having a base pot and an insert pot, the latter removably inserted into the base pot. The base pot has a bottom and tapering sides, an open top, a drain hole in the bottom, and legs on the bottom for elevating the base pot above a surface. Clearance holes are provided for plumbing to be disposed under the base pot bottom. A pipe fitting is disposed in the drain hole for connection with a drain line. Stand offs are formed in the base pot for supporting the insert pot. The shape of the insert pot conforms to the base pot with slightly smaller dimensions and includes a basin portion with a plurality of drain slots. When placed on the stand offs, the spaces between the basin portion, the insert bottom, and the interior sides and bottom of the base pot provide a volume through which water may drain from the insert pot into the base pot and through the base pot drain.
