Urban Worm Thermometer - Perfect for the Garden & Worm Bin

Worm Bin Thermometer — Know Your Bin's Temperature at All Times

Temperature is one of the most important variables in a healthy worm bin. Too cold and your worms slow down significantly. Too hot and you risk a die-off. The Urban Worm Thermometer gives you an accurate, at-a-glance read so you're never guessing.

Features

• Stainless steel probe penetrates up to 5 inches into soil or bedding for an accurate core reading — not just surface temperature
• Color-coded dial with green, yellow, and red zones — instantly shows whether your bin is in the optimal range for worms and soil microbes
• Works equally well in garden beds, raised beds, and compost piles
• No batteries required

Optimal Worm Bin Temperature Ranges

• Red Wigglers: 55°F–77°F optimal, tolerant to 40°F–90°F
• European Nightcrawlers: 70°F–80°F optimal, tolerant to 45°F–90°F

A simple tool that pays for itself the first time it saves your colony from a heat spike. Available as a single or a money-saving 2-pack.

Works great inside an Urban Worm Bag Version 2. Browse more worm bin supplies.
