Moisture sensor meter
If self-watering pots are too futuristic for your taste, and you want to stick to the basics of gardening, there’s a gadget for that too. The Indoor/Outdoor Moisture Sensor Meter offers another way to bypass the common problem of under-watering and over-watering thirsty house plants. The easy-to-read needle meter has a color-coded gauge that reflects a plant’s soil water levels, with no batteries needed.
