The Greenhouse-IV Controller from Green Air Products provides complete control over all aspects of a greenhouse or indoor grow room environment. We have gone to great lengths to learn about this product and understand its functionality. In the environmental control world, the GHC-IV is the omnipotent king of controllers. At first glance it can seem extremely complex, but once you become familiar with it, it is fairly simple and user friendly. If you are a grower considering a controller of this caliber, we feel that we are unique in our ability to assist you with clear and concise knowledge and the unending support you deserve. We will continually be updating our resources and information, and we guarantee that we will be the industry leader when it comes to the GHC-IV.

Remote Access and Data Logging
The controller is operated manually from the unit itself, or it can be connected to and operated via computer, allowing for local or remote access. Remote access can be achieved effortlessly with the help of Windows® XP Pro and its built-in remote access capabilities. Alternatively it can be implemented with the help of remote access software such as PC Anywhere®. Sure, go to Kalamazoo! Or even Timbuktu! As long as there is an available phone line, there's the GHC-4, with its trusted readings and your piece of mind. Computer interface connections on the unit will allow easy monitoring, data logging or control.

Environmental Monitoring
The Greenhouse Controller comes standard with five external sensors to help it keep track of the environment. It monitors nutrient levels via conductivity and pH probes. It senses other environmental factors with the help of its remote humidity and temperature sensors. Light is sensed via the built in photo sensor which automatically turns off CO2 equipment in the dark.

pH and Nutrient Control
Optional Metering Pumps are used to accurately dispense corrective additions of pH down or nutrient adjusters to automatically maintain desired solution parameters. In the picture to the left, the GHC-IV is being used with three pumps to dispense a two part nutrient solution and a pH adjuster. Plug pump(s) directly into the GHC-IV and set the values you want. Adjustable flow rate from 4 to 13 ml per minute.
Click here to see an economical alternative, using only two pumps. To achieve this, a grower may use a single part nutrient solution and use only two pumps. (We suggest Ionic Nutrients.)

CO2 Control
CO2 can be controlled via the internal CO2 timer, or for optimum efficiency, with the help of an optional CO2 monitor. When temperature or humidity rise to high levels (common with CO2 usage), the vent fan turns on, the CO2 turns off, money is saved, a sigh takes wing, a flower blooms, happiness is glimpsed.

One Box to Rule Them All
The GHC-IV is fantastic because it controls such a wide variety of equipment: CO2 production apparatus, humidifiers, pH and nutrient dosing pumps, fans, cooling equipment and irrigation pumps will all plug directly into the 120V outlets
