Mega Mass - 3-in-One Soil Meter

Stop guessing when to water your plants. This soil moisture meter makes it easy to know exactly when your soil needs water, helping prevent the two biggest causes of plant problems: overwatering and underwatering. Simply insert the probe 3–5 inches into the soil, wait a few minutes, and read the results. The meter measures soil moisture, while also offering optional pH and light readings to help you better understand your growing environment.

The meter is solar powered, so there are no batteries required. Just place the probe in the soil and let the built-in solar panel power the reading. This makes it a reliable, low-maintenance tool for houseplants, vegetable gardens, lawns, raised beds, and greenhouse growing.

It’s especially useful for indoor plants, where watering mistakes are common. Whether you grow orchids, houseplants, vegetables, or herbs, a soil moisture meter helps you water at the right time for healthier roots and stronger growth.
