Dr.meter Soil Moisture Meter, Plant Water Meter for Garden Lawn Farm Indoor & Outdoor Use, Soil Tester Hygrometer Sensor for House Plants, Gardening Gifts, No Battery Needed

Do NOT under any circumstances submerge the probe in water, especially to test if it "works" as so MANY reviewers have done. It'll just stop working. I have over 100 plants. I use my moisture meter consistently with pretty good success and it's never failed me. Moisture meters are designed to work in soil ONLY and will not provide a reading in water. Leave it in the soil between 30-60 seconds, not longer and NEVER more than 5 minutes as this can corrode the probe, which is sensitive. One thing to keep in mind is the reading will depend on the depth and location of the probe in the soil. Soil might be very moist towards the bottom and dry in the first couple inches. Dry on one side and wet on the other. It all depends on how evenly you water your plants. A lot of the complaints are by people who are not aware of these factors. Different plants have different root systems. Some naturally have shallow roots, while others head straight to the bottom of the pot. So how deep you place the probe is very important. Under normal conditions—and this is likely the problem many are having—mineral salts, coming from fertiliser and tap water tend to build up in potting soil over time. So, unless you re-pot annually, changing the old soil for fresh soil, readings will gradually become less and less accurate. If the soil is heavily contaminated with mineral salts, the meter will always read moist or wet, even when the soil is obviously dry. Also, over time, often in as little as a year, mineral salts slowly penetrate the probe itself, or it may begin to rust and, again, both situations can lead to inaccurate results. Always dry off the probe immediately after use! Moisture meters actually read electrical conductance, not the amount of water present. Water is a good conductor, but air (which is abundant in dry soil) is not. That’s the basics of how a meter works. Remember how air is a poor conductor? Freshly potted plants have fluffy airy soil compared to old pots with compacted soil. That’s going to skew your readings. It's also important to know that because moisture meters work by measuring electrical currents within the soil, soil that has a high salt content will result in inaccurate readings. The numbers given are usually just a scale, not an actual measurement. So you should be checking the output against a specific plant’s water needs, because not all plants need the same amount of moisture. Sometimes a 7 means water, sometimes a 7 means wait. If the needle in the display window is bouncing around and does not settle, the probe could be touching a small rock or piece of metal in the soil. Remove the probe and try again in a different location.

Super pour voir si vos plantes sont sèches ou humides

Love this moisture meter! Easy to use and very accurate. I’ve been using one for years! Works great and helps me to keep my plants alive by not overwatering them. I recently bought this one for my daughter, and I gave my mother one last year. My mother loves it also!

Geeft goed weer hoe vochtig de grond is.
