The Autopilot APCET Temperature Controller is an analog 24-hour day / night cooling or heating thermometer. 

The Autopilot Desktop CO2 Monitor has an easy-to-read LCD display with independent CO2, relative humidity and temperature readings. 

The Autopilot Digital Environmental Controller (DEC) is designed to control the humidity and temperature levels in your growroom while coordinating the use of supplemental CO2 injection within the temperature function. 

If you use an Autopilot Greenhouse Master Controller, this access kit gives you complete control of the unit from any location. 

The Autopilot Greenhouse Master Controller (GMC) precisely controls the temperature, humidity, and CO2 levels in your growing area. It also provides Day/Night temperature set-points. 

The Blueprint Analog Atmosphere Controller controls up to four 120V devices with dedicated receptacles for cooling, humidity and CO2. 

The AIR-1 allows you to control the temperature and humidity within your growing environment. 

The AIR-2 allows you to control the temperature and humidity within your growing environment, using separate temperature and humidity outlets. 

The AIR-3 expands our line of atmospheric controllers by providing the ability to coordinate supplemental CO2 with your ventilation equipment. 

The C.A.P. AIR-3DN separately controls the day temperature, night temperature and CO2 production within the growing area. External temperature probes have proven to be highly accurate and reliable. 

The AIR-4 operates independent temperature and humidity control, coordinated CO2 sequencing and an additional outlet that is powered only while the lights are on. 

The CGC-1e Complete Greenhouse Controller controls all of the main devices required in today's modern hydroponic garden. Your garden's HID lights are controlled by a precision 24-hour time clock. Two outlets are provided for your lights. 

The HLC-1e allows you to control the temperature within your growing environment. It can also be usedr as a high temperature shutdown to protect your garden. 

The HLC-2e HID Lighting Controller will prevent your HID light from Hot starts. A Hot start occurs whenever your lights are turned off and then back on before the lamps are allowed to cool off. Hot starts are usually caused by power outages and they reduce your lamp’s life and intensity. 

The HLC-3e HID lighting controller combines the functions of the HLC-1e and HLC-2e to protect your expensive HID lights from hot starts and your garden from high temperatures. 

The HPR-1 is a hard-wired 30 amp capacity, 240 volt version of the UPM-1. The HPR-1 is perfect for controlling higher loads such as large air conditioners or multiple HID ballasts. 

The HUM-1 is perfect for orchid growers! 

The C.A.P. TMP-Dne gives you complete control of your grow room temperature. 

The UPM-1 Universal Power Module is a unique device that lets you control and run two HID lights, fans, coolers or other high amperage 120 volt equipment. 

The XGC-1e is the best all-in-one controller ever made. It is identical to the CGC-1e, except for the addition of Fuzzy Logic(tm) CO2 control! Fuzzy Logic(tm) gradually keeps the CO2 level at your desired setting, without going over the set point. 

This quality Centrifugal Humidifier features a multi-directional fogging head that spreads moisture evenly throughout your growing area. 

Designed to turn "On" and "Off" exhaust fans and/or intake fans to remove unwanted atmosphere due to heat or humidity. 

The Green Air CT-HT-2 controller features fully independent sensors for cooling and heating equipment. The cooling thermostat activates the left outlet of the controller and the heating thermostat activates the right outlet. 

The Green Air HAR-1 power relay uses high amperage capacity contacts to transfer power to large fans, pumps or lighting systems requiring high voltage or amperage service. 

The Micro Climate Controller MCC-1 is designed to perform all the major atmospheric and timed functions required in an automated growth environment including temperature, humidity, carbon dioxide enrichment, lighting and irrigation control.  

Designed specifically for the control of plant growth and related environments. Perfect for plant zone environments, reptile habitats or any other application requiring automatic switching of heating and cooling equipment. 

Control humidity automatically and accurately with Green Air Products THC-1 Total Humidity Controller. Switches 120V at 15 amp maximum. Sensor allows a 7% (differential) comfort zone between "on" and "off" functions. 

Compatible with a Gro1 Wireless Weather Station, use this wireless sensor to monitor an additional growing area. 

The Gro1 Wireless Weather Station is a great way to keep track of temperature and humidity levels in multiple growrooms, grow tents or greenhouses. 

The Grozone TEMP-1 Day and Night Temperature Controller operates cooling or heating equipment to maintain optimum temperatures in your grow room. 

A dual analog thermometer and hygrometer that's waterproof! 

The Sentinel MDT-1 combines two timer functions into one unit - it controls supplemental lighting, 120 volt devices that have to be "recycled" ON and OFF at precise intervals, plus nighttime (or when lights off) operations. This 100% digital and programmable timer has an easy-to-use menu, simple pushbutton programming and a bright LED display that's easy to read. 

With the Sunleaves Hygro-Thermometer, keeping tabs on your indoor garden has never been easier. 

Keep track of humidity and temperature readings at a glance with a Sunleaves' large display Hygro-Thermometer. The digital numbers are big enough that you can easily read them from across the room! 

Built by Titan Controls, the Sunlight Supply EOS 1 Humidity/Dehumidity Controller is the complete solution for controlling the humidity levels in your grow room. 

The Titan Controls Zephyr 1 day / night temperature controller was designed specifically for grow room conditions.
