The Proleaf CO2 Regulator and Solenoid kit is a precision regulator, flow gauge, and industrial solenoid valve that comes with 5 metres of plastic dispensing tubing, and an Australian standard 240v Plug.  

This unit should be plugged into the Proleaf CO2 controller (click here) which reads the CO2 levels in your grow area and adds CO2 to the correct level. We recommend levels of 300ppm-1000ppm for normal growth, and 1000-1500ppm for enhanced crops. DO NOT exceed 2000ppm or plant damage will occur.

DO NOT spend time in CO2 rooms that are not ventilated every 1-3 days as oxygen levels and CO2 levels may be dangerous for humans. Above 1000ppm limit exposure time, and do not spend time in a room with over 3000ppm. Limit exposure time above 1000ppm and DO NOT spend time in ANY room with over 3000ppm. This is extremely dangerous.

Familiarise yourself with safe CO2 levels before using any CO2 device. Symptoms of too much CO2 may not be noticed by the affected person. Ideally, clear your lungs in outside fresh air after using the grow room. Another person should be present to check you do not have blue fingernails and do not spend too long in the grow room.

CO2 is safe to use when used in a responsible manner. As we are unable to control your use of CO2 systems we feel it necessary to ask you to learn more about CO2 poisoning before use.
