REOTEMP K83W Worm Therm Soil Thermometer with Worm Composting Digital Guide for Red Wiggler Compost Bins

Works great - Its not just the air temp. you need to know in the spring for planting - Its the soil temp too !

It does what it's supposed to, and it's nice having the worm temperature range highlighted; I also bought a generic compost thermometer and I always have to remember to mentally change from normal compost temps to vermicomposting ones. I wish it came in multiple lengths though. I could use one a few inches longer.

Right now it is summer and the temps are approaching a 100 degrees. I am new to raising worms and was starting to worry about the health of the worms in my six bins as the temps started rising above the 90 degrees that can kill composting worms. I have initiated a couple of minor precautions that have kept the bins 15 to 20 degrees cooler than the outside temps. Some of these precautions are using white bins, keeping bins in shade, digging bins into the dirt, putting shredded wet cardboard on top of the bin soil and wet old towels on top of the bins themselves for evaporation cooling. Due to summer heat, I use this Thermometer daily, and I will likely have to use the thermometer and other precautions in in winter as well to keep my worms as close to 70 degrees as possible.

Super fun tool for my students to check composting worms temperature!!

Both came with battery included. I have 1 in my grow tent and 1 inside. Happy with the purchase.

does the job

It's as simple as just sticking it in the dirt and immediately seeing the temperature.

You always want to buy an instrument that's measurement parameters are as close to the expected conditions as possible. This dedicated worm farm thermometer from Reotemp is exaclty that. It's not the cheapest thermometer some worm retailer could find to slap their brand on. Thermometers are Reotemps specialty. Thats why I chose it. I wanted a good thermometer so I went with a thermometer company. Reads quickly and accurately. Reotemp will definitely get a look for all my future instrument needs.

Perfect temperature

Works great.
