FAQ

Q: Will a Moisture Meter Damage the Roots of My Plants?

Moisture meters won't damage the roots of your plants if installed properly. As a general rule of thumb, the probe should only be inserted 1/2 to 2/3 of the way down the pot from the surface—as long as the probe doesn't touch the roots, it won't cause any damage.

Q: Is a Plant Moisture Meter Worth It?

Yes, due to over/under watering being a key issue in the death of many houseplants, a moisture meter is worth the investment if you want beautiful, healthy houseplants.
