3 in 1 Measuring materials: With a single tool you can quickly check the humidity and pH levels of your worm beds, two very important points for the proper development of your hatchery. In addition, this tool allows you to measure the light of the ground.
It will help you control the levels accurately. The worm lives in substrates with a pH of 5 to 8.4 and humidity must be between 70 and 80%.
Outside these levels, more or less serious problems may appear on your farm.
