VIVOSUN Plant Soil Moisture Meter, 3-in-1 pH Tester, Indoor & Outdoor Use

Just great! Now I have one for the living room area at the front of the house and my old one in the den at back. I have plants all over, and this is a life saver.

This is actually the second Hygrometer I have gotten, the other one just tells me the moisture level of the soil. But this one also tells you the pH and the light levels. It is really easy to use, just stick it in the soil. I nearly killed my Knockout rose plant by too much watering, and after I repotted it and read up on how to care for it, I am REALLLLLY careful about how much water it is getting. I check the hygrometer then to a "finger test" (stick my index finger deep into the soil) to double check the moisture level. So far my Knockout Rose is sprouting leaves again, and i think it is because of the hygrometer and the "finger test". I would definitely recommend this

I am very sorry to report that this meter isn't very useful for my needs (growing succulents outdoors in containers in the Bay Area). The problem is that the sensors read the same unless conditions are truly extreme. For example, the light meter does show a high reading for bright sunlight directly on the sensor. But it can't tell the difference between bright shade and deeper shade. The moisture meter - which was my reason for buying the item - registers in the red, "Very Dry" region unless the meter is placed in soaking wet soil. Then it does go all the way to "very wet". So, the moisture meter is probably useful for soil that is usually quite moist, to warn you if it dries out. But it's not useful for succulent growers. (Maybe if you haven't figured out yet why all your succulents die...) Finally, the pH meter seems to be entirely useless. It reads highly alkaline (above pH 7) unless placed in soil soaked in vinegar. But this is *not* a problem with this specific plant sensor. It is a problem with affordable plant sensors in general. I did a lot of research on the topic after I got a second Vivosun meter that performed as described above. Basically, you have to spend $50-$100 to get a sensor that will probably work. The really good ones start at around $320. Soil sensors, it turns out, are a huge business. They are a crucial component of up-to-date agriculture. They allow automation - and save water, reduce chemical use, etc. Goals everyone can cheer for. Those sensors, placed permanently in the ground at many locations on a farm, are part of multi thousand $$$ systems. The $300-$1500 handheld sensor is for the person who goes around checking on actual conditions. Less expensive systems exist for gardening, but again, they're designed to be incorporated into irrigation systems and so on. There are also at least 4 fundamentally different technologies used in soil sensors. (I'm ignoring the light meter here. Also, some technologies can measure both pH and moisture content like this meter - I think they're both measuring electrical potential between the two sensor prongs. But the more accurate and expensive tech only measures moisture. I guess they have a different sensor for pH, or more likely, it's not incorporated into automated irrigation systems.) The more accurate tech is cumbersome and has been developed largely for permanent installation in agricultural settings. There are a couple of in-between levels that are also marketed for agriculture; these are the types that appear in garden systems. Finally, the technology used in inexpensive moisture meters is no longer used in serious equipment. I don't really understand why a $10 moisture meter can't work a bit better, though. Some tinkering with the probe materials and adjustment of the sensor readout range might well make this type of meter work considerably better. Leaving out the other sensors would reduce costs and confusion. There is a big consumer market for moisture meters that get the right basic answer. Everyone with a houseplant could use something like that. Never mind the enthusiasts who fuss over tricky plants from succulents and cacti to marsh living carnivorous plants! So, for now, succulent growers should just avoid these devices. (There's no reason to imagine another brand is better.) It would be interesting to know if people whose plants need moist soil find this type of meter more useful. And Vivosun (one of the top companies in the indoor horticulture area) should go back to the lab. Plants in containers don't allow for the expensive, high-tech systems I referred to above. Each container needs a sensor of its own. So, users need many separate inexpensive small sensors. Given the money in some forms of indoor horticulture, it seems worthwhile to develop a moisture sensor that's still inexpensive, but two or three times as accurate as this one.

Can't beat the price. It seems very responsive to light and water levels... I knew that my soil pH was way too alkaline to start out with, so it doesn't really move the needle, and it's hard to tell sensitivity, but I believe it. 😆 Hopefully, I get the pH down in my soil soon and we'll know more soon. Happy with this purchase -here's to hoping my plants will be happy soon. 🙃

The reason I bought it was because in the picture it shows the letters are white and easy to read. And then I got it. I can’t see a dang thing , because the letters are the same color as the casing. So I had to write MLP in the spot so I know what it is. Besides that it’s an OK meter it works for the bottom of the line product. I ran both moisture and pH test in some leftover soil in a pot. Saturated one side and left the other side dry, both read. As for the PH. I diluted distilled vinegar and some water and pour it into the soil and let it sit for 10 minutes. Soil went from 7.5 to 6.5 so it read the change. Overall, like I said earlier, it’s not bad for an OK bottom of the line product. You just can’t see the letters. This would be great for a beginner.

At first it showed the PH being 6.5 which cannot be correct since I use Happy Frog soil. But I thought I’d use it for moisture only. It rained hard , over an inch of rain and even the topsoil was wet. It showed dry. It is cheap Chinese junk that does not work.

I already have one and use it for indoor plants and to check my outdoor bushes so I know when they need watering which helps me out a lot! I bought this one for my daughter! Definitely recommend.

I learned that I needed one of these and started to do some shopping here on Amazon. Talk about OVERLOAD! If one isn't really knowledgeable because it's your first time needing one, it is OVERWHELMING trying to pick ONE that meets your needs, doesn't cost an arm and a leg and just isn't complicated. This is EXACTLY what you need if you are using soil. Works great, easy to read, accurate, easy to clean, seems durable enough, no problems there, not cheaply made. Everything I need, not complicated or expensive! If you're looking for that, this is a great find! I totally recommend it! If you need something for hydroponics or anything more complicated, this would not fit your needs!

This product worked great initially, but after a few months began to display corrosion on the rods before no-longer working. The product works, but unfortunately don't expect this to last longer than perhaps a season.

سيئ لا انصح بشرائه، عندما جربت الجهاز على التربة الزراعية قياس قوة الضوء يعمل وقياس الرطوبة يعمل لحد ما اماً قدرة قياس قلوية وحموضة التربة لا تعمل ابداً ، جربتها على عدة أنواع من التربة وكذلك على ماء من الحنفية ويعطيك نفس القراءة، إذا كنت لاتهتم بقياس قلوية التربة فالجهاز مناسب، أما إذا كانت هذه الميزة مهمه فأنصح بعدم الشراء

Good Product to measure Moisture. Other function accuracy is questionable

Product worked well for the first month I had it. Too bad it stopped working right after my return window closed. UPDATE My first review commented on how it stopped working but it seems to be reading correctly now and have been using it for regularly and it is very helpful.
