Q1 Is TerraProbe easy for beginners to use?
Absolutely. Its intuitive design and clear digital display make soil testing simple, even if you've never done it before.
Q2 Can I use it for indoor plants?
Yes! Its compact size and versatile testing modes work great for houseplants as well as garden beds.
Q3 How often should I test my soil?
We recommend testing every few weeks, or before planting season. If you notice plant stress, test more frequently to catch issues early.
Q4 Is the device waterproof?
The probes are built to measure moisture, but the main unit isn't fully waterproof. Keep it away from heavy rain or submersion.
Q5 Does it work with hydroponic systems?
Yes, TerraProbe accurately measures pH levels in hydroponic setups, helping you maintain the perfect environment for your plants.
Q6 How long does the battery last?
With normal use, the battery lasts several months. An auto-shutoff feature helps extend its life even further.
Q7 Do I need to calibrate it before use?
Not at all. TerraProbe arrives pre-calibrated and ready to test the moment it's out of the box.
Q8 Can it identify specific nutrient deficiencies?
While it won't name exact nutrients missing, the fertility reading flags when your soil needs a nutrient boost.
