  • Sentinel C02 Regulator

    Reduces the pressure of the CO2 exiting the tank, controls the flow of CO2 with a solenoid valve and regulates the amount of CO2 being released with a precision ½ to 15 SCFM flow-gauge. The CO2-REG CO2 regulator assembly comes complete with all of the required devices to make using compressed CO2 easy. 120v

    Sentinel has taken digital accuracy and combined it with ease of use. Its one-touch functions make using its products easy. Gone are complex sub menus that are confusing and time consuming to navigate. Many of its products will serve more than one function (such as heating or cooling control) making them extremely flexible and capable of being used in many situations. All Sentinel products were designed to maintain a very high degree of reliability while performing critical functions. In some cases Sentinel offers innovative designs that are so unique there really are no other products available for comparison.

  • Hydrofarm CO2 Regulator (tank required)

    CO2 is an odorless, invisible, and non-flammable gas. It is also safe for humans in the maximum concentrations recommended for plant growth. The average level of CO2 in the atmosphere is about 300 PPM (parts per million). If the level decreases down below 200 PPM in an enclosed growing area, plant growth slows to a halt. Through the years of testing and research, the optimum enrichment level of CO2 for plant growth has been agreed to be about 1500 PPM. With CO2 enrichment, under good conditions, plant growth rates and flowering will increase 20-100%. CO2 can be used from seedling right through harvest.

    the COREG is a replacement part for the HF COSYS.

  • Autopilot Digital CO2 Controller Fuzzy Logic

    Autopilot's simple to use highly accurate digital CO2 controller has arrived. Autopilot's digital CO2 controller measures the carbon dioxide level in the grow room and automatically turns on and off the CO2 device to accurately keep the carbon dioxide PPM at the desired level. The Autopilot digital CO2 controller can be selected to operate in Fuzzy Logic mode or standard logic CO2 injection within the room. When used in Fuzzy Logic mode, the built in microprocessor will apply the calculations to the injection schedule which eliminates the guess work and maintains CO2 levels efficiently. Standard logic CO2 controllers will not make these calculations and will continue to inject more and more CO2 into the room until the controller reaches its set-point. Standard CO2 injection methods do not allow enough time for the carbon dioxide to mix with the air. Standard logic CO2 controllers may be fine when using a CO2 generator which costs very little to operate, but can be costly and inefficient when using bottled CO2 tanks. The Autopilot Digital CO2 controller has a 15 ft remote CO2 sensor with built in photocell. Controlling CO2 has never been easier or more affordable. Autopilots digital CO2 controller eliminates guesswork while it controls your carbon dioxide level with accuracy and efficiency. Autopilot offers guidance for your growing environment. 15 ft remote combination probe, CO2 and light Accurate dual beam CO2 sensor Adjustable CO2 Dead-Band Fuzzy Logic mode adjustable (on/off) Built in data logger stores high and low readings for CO2 PPM
