THE PROBLEM
THE FINGER
TEST LIES.The top inch of soil dries out fast. The root zone, two inches down, can stay swampy for days. So you water on schedule, the roots drown, the leaves yellow, and you blame yourself. The number one cause of houseplant death is overwatering by people who were trying to do the right thing.

THE FIX
ONE PROBE.
ONE HONEST ANSWER.Slide the probe down to the roots, where it actually matters. The dial reads DRY, MOIST, or WET in seconds. No batteries to die. No app to update. No subscription. Just a calm, confident answer every time you walk past your plants.
HOW IT WORKS
THREE STEPS. ZERO GUESSING.
-
01 - INSERT
Push the probe 4 to 6 inches into the soil, close to the root ball. Avoid hitting roots or stones.
-
02 - READ
Watch the dial settle. DRY, MOIST, or WET appears in a few seconds. No batteries, no calibration.
-
03 - DECIDE
Water only when the dial reads in your plant's preferred zone. Wipe the probe, move to the next pot.

QUESTIONS, ANSWERED
THE FAQ.
Do I need batteries?
No. The probe is fully analog. There is nothing to charge, replace, or update. Take it out of the box, push it in the soil, read the dial.
Can I use it outdoors?
Yes. Indoor pots, outdoor containers, raised beds, and in-ground garden plants all work. Just don't leave it sitting outside in the rain when you're done.
How deep should I push the probe?
Aim for 4 to 6 inches, right around the root ball. That is where the plant actually drinks. The top inch lies.
Will it work for succulents and cacti?
Yes. Use it to confirm the soil is fully DRY before you water. That single habit will save more succulents than any other tip we can give you.
How long does it last?
Years, with light care. Wipe the probe with a dry cloth between pots so soil and minerals don't build up on the tip. Don't pry rocks with it. That's it.
