Moisture Meter, Small

Never go dry again with this moisture meter. To prevent over or under watering, simply stick into your soil, and you'll know it's time to give your plants a drink when the color changes. The simple design goes well with any pot type. Wilted leaves? Not in this house. Root rot? We don't know her.  SM: Recommended for 2"-4" pot diameters. Compatible with potting mix, barkdust, peat moss, and semi-hydroponic setups. Color of meter itself may be green or white. Designed by Tetsutaro Nakabayashi. Researched and tested by the Tokyo University of Agriculture.
