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 CAP TMP-1 cooling thermostat is extremely easy to use and you can reset the temperature setting at any time with the twist of a knob. 

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.

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.

A dual analog thermometer and hygrometer that's waterproof! 

Sentinel has replaced the CHHC-1, with the CHHC-4 Temperature, Relative Humidity and CO2 Controller. It looks the same so you will be comfortable making the switch, but inside, there are several improvements. 

The Sentinel DRT-1 digital recycling timer has an easy-to-use menu, simple pushbutton programming and a bright LED display that's easy to read. 

Temperature, humidity and CO2 are all environmental conditions inside a growing area that need to be controlled for successful gardening. The Sentinel EVC-1 Environmental Controller controls all three and more. It's simple-to-use and reliable, yet affordable. 

Sentinel combined digital temperature and humidity controls together in one flexible unit called the EVC-2 Environmental Controller. Additional features include activation of a Night Device AND a CO2 device. 

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. 

When you need to control larger equipment with higher amperage, or when you need to increase the number or size of the lights, fans, air conditioners or pumps in your growing area, the Sentinel PXM-1 or PXM-2 is your answer. 

The Sentinel Therm-1 cooling or heating thermostat is an economical way to regulate temperatures in your growing area. 

Temperature should be the first priority when considering how a grow room will be setup. The Sentinel UTC-1 Universal Temperature Controller solves the Day and Night temperature difference problem by taking temperature control and monitoring to the next level for a variety of set-ups. 

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!
