NICREWDigital LED Heating and Cooling Temperature Controller, Reptile Thermostat for Snake, Lizard, Tortoise, Vivarium and Other Reptiles, 1100W 220V

I have been using this paired with a cheap reptile terrarium heat pad inside a cool box to grow Koji for Miso and Sake and other fermentation projects. It can easily maintain 32c. It is designed such that you simply plug a heatpad into the open plug socket and plug the device into the wall. My only small critique is that when setting it up the temperature it doesn't ask you to set a range to maintain but rather asks you to put in a maximal value at which it will turn off and a difference value beneath which it will turn on. This amounts to the same thing but I did have to re read the instructions a few times. In all fairness this is primarily aimed at he as ting terrariums where I am sure desirable parameters are different.Previously I have (poorly) wired my own temperature and humidity controller as Humidity/Temperature controllers like InkBird with two plugs are quite expensive. However I have been having great success with my Koji simply covering my grains with a plastic bag or cling film to keep humidity in.In my experience it is poor temperature control not poor humidity control that kills Koji most often. This device maintain temperature excellently and if you do wish to grow Koji specifically I don't feel humidity control is a must, just steam the grains so they are not at all mushy or stick together (undercooked if anything) and then cover to keep the bulk of the temp in with just enough space to let air flow (another factor majorly over emphasized online in my opinion).This device maintains temperature at 30-32c in an insulated container and does not exit these parameters, it's quite cheap and so I would highly recommend it ( for fermentation).

Bought this to regulate the temperature in tortoise vivarium. Absolute amazing. Definitely well worth the money eady to setup. I would definitely recommend this.

Easy to use, good price, does the job

Good product works well with our bearded dragons heating

Fantastic product, however the packaging could do with being reinforced when out tor delivery. I don't l8ke the fact Amazon parcels come with the products original box with just the address label printed out annd stuck on it..the box was partly opened on delivery. Driver said it must hav3 come poose in transitGrwat oroduct though for my daughters Ball Python.will definitely buy again

So I got this product to heat a tube heater which is placed in an insulated box I have over my solar panel batteries for cold weather protectionI just wanted the heater to come on only when the temperature dropped to a certain temperature and then heat up to a certain temperature then go off againThe instructions on this are really poor and confusing so I'll explain them so people can figure it outso let's say I want my batteries to be at 20°c and if the temp drops to 17°c for the heater to come on until it reachers 20°c again and then turns offFirst off use the up-down keys to set your start temperature so I pressed until it was 20°cThen press the "H/C" button to "heat" so it would come on the heat something up increase in tempThen press "set" Here you can set the drop in temp before you want my heater to switch on so I set mine to "3.0°c" which would be 20°c minus 3.0c = 17°cPress "set" again and you come to the "delay" This is how long you want the delay before it switches on your plugged-in equipment. I set mine to 002 so it comes on almost instantly when the temp hits -3° from my set temperatureIt took some playing around with I had a cup of cold water to rapidly make the temperature drop, you could have a hot cup too if you want to increase itTo do this for Cold you have to press the H/C button to "cool" - I would guess you follow the logical pattern but for an increase in temperature it would then turn on your equipment

I've got 4 of these now for all my jumping spiders and tarantulas!

Unfortunately broke within two months of purchase. Worked well prior. I'd recommend a different brand
