Ecotechnics Evolution Co2 Controller Carbon dioxide is one of the most important factors in an indoor grow room. Photosynthesis is the term used to describe the process by which plants combine CO2 molecules with water molecules to form complex sugars, there is a resultant spare oxygen atom which is released back into the air, the sugars being further processed by the plant to form natural polymers for growth. The ambient level of CO2 in air is 300-400ppm, fast growing plants in your grow room can use all the available CO2 in less than an hour slowing photosynthesis and therefore growth to a virtual halt. The Evolution digital Carbon Dioxide control system is the most advanced carbon dioxide controller in the world with 4 modes of operation it can be used with or without a CO2 monitor and can also control extractor fans by internal timer or by interface to an external thermostat or humidistat, it also has the ability to make predictive dose settings based on actual read values when used with an analyser. Plants grown with enhanced CO2 levels grow much faster and bigger resulting in increased yields and decreased crop cycle times. This Controller one of the most advanced of it's kind and has more features and has lots of functionality. It can be used either with or without the Evolution Carbon Dioxide Sensor and can be interfaced to an external thermo / hygro stat providing a cheap entry level system with an easy & affordable upgrade path in the future.
