Stop guessing when to water. Push the probe into the soil and the needle tells you if it's dry, moist or wet. Flip the switch to read light level or soil pH. No batteries, works in any pot.
Why you want one
Overwatering kills more houseplants than anything else. A moisture reading at root level — not the surface — is the fastest way to learn what each plant actually needs, and the perfect companion to a self-watering planter while you dial in refill timing.
