Half-Price - New C.A.P. PPM-4 CO2 Controller - Crazy Deal-O-Rama:£39[hoGarden & Outdoor_3728299ua]

CAP's PPM-4 is a safe, easy to install, and operate CO2 Controller for any growing environment. The controller features 2 pieces, an electronically safe 120v wall plug and a wall-mounted infrared sensor connected together with a 10 foot power cord. The PPM-4 comes factory calibrated and programmed with an optimal CO2 maximum controll set point of 1450 PPM. I had opened this Estate Sale find (that was sealed) to ensure it is operational. It will be sent in its original packaging.
