The Inkbird ITC-608T is a plug in controller with two switched outlets and separate temperature and humidity probes. It turns heaters, coolers, humidifiers, and dehumidifiers on and off automatically to hold the conditions you set, and it handles up to 1800 watts at 120 volts.
It fits growers running tents or greenhouses, mushroom cultivators, home brewers, and cheesemakers who want environmental controllers that manage both heat and moisture from one unit. The 1800 watt rating covers both outlets combined, so total the wattage of everything you plug in.

Running Heat and Humidity Equipment Automatically in Grow Tents, Fruiting Chambers, and Cheese Caves
If you are trying to hold a grow tent at a steady temperature while also keeping humidity in range, or you need a mushroom fruiting chamber to stay damp without overshooting, this controller replaces the separate timers and dials you might otherwise juggle.
Plug a heater or cooler into one outlet and a humidifier, misting setup, or dehumidifier into the other, set your targets, and the unit switches each device based on probe readings. With only the temperature probe connected, it can run heating and cooling together, which helps in a greenhouse that swings between cold nights and warm afternoons.
The compressor delay matters if you are converting a fridge into a fermentation chamber or cheese cave, since it keeps the compressor from restarting too quickly.
What to Expect from the Inkbird ITC-608T in Real Use
Purchasers describe setup as straightforward and the large display as readable from a distance, showing both conditions and which outlet is running. Several replaced rheostats and humidifier timers with it for tighter control.
Owners run it on a fridge and humidifier as a cheese cave, in grow areas, and on a crawlspace dehumidifier that has worked for seven months, where placing the probe on the opposite side of the space from the dehumidifier solved their humidity problem. In high humidity work between 85% and 98%, the humidity probe stays accurate rather than maxing out the way some controllers do.
The included instructions are a weak point. They read as a rough translation, so stepping through the menus with the manual open is the easiest way to learn the settings. Some owners weren't sure how to adjust the gap between target and trigger temperatures, and one wished for a waterproof temperature probe.
A separate owner had a unit fail and received a replacement from Inkbird. The long power cord can eliminate an extension cord in many automated climate setups.

Frequently Asked Questions
Is the Inkbird ITC-608T good for mushroom growing?
Yes. Mushroom fruiting chambers typically run at very high humidity, and the ITC-608T's humidity probe reads up to 99% RH and holds accurate readings in the 85% to 98% range where many controllers struggle. With both probes connected, you can control a humidifier on one outlet and a heater or cooler on the other, so you manage moisture and temperature together from one unit.
What does compressor delay do on a temperature controller?
Compressor delay sets a waiting period before the controller turns a cooling device back on after it shuts off. Refrigerators, freezers, and air conditioners use compressors that can be damaged if they restart too soon, while pressure in the system is still high. If you are controlling a fridge for fermentation, curing, or a cheese cave, set a compressor delay of a few minutes so the cooling outlet doesn't cycle the compressor on and off rapidly.
Where should you place the probes on a temperature and humidity controller?
Put the probes where they read the conditions of the whole space, not right next to the equipment being controlled. A humidity probe sitting beside a dehumidifier or humidifier will reach its setpoint quickly and shut the device off while the rest of the space is still off target. In a crawlspace, tent, or chamber, place the probes on the opposite side from the equipment and at the height of your plants, mushrooms, or stored goods.
