4-in-1 Soil Moisture Meter, Moisture Meter for Plants, Soil Ph Meter, Tester for Moist, Light, Nutrients, pH, Great for Garden, Lawn, Farm, Indoor & Outdoor Use，No Battery Required, Blue

Great for a beginner gardener, Planted some hydrangeas and almost killed them for under watering it, gives moisture readings, PH levels good size easy to read two thumbs up

This was a little more than I wanted to spend but now that I have it, it’s totally worth it. I’ve never had one that tested the nutrients in the soil. I love the rotating head, it looks nice, works very well, is very accurate. I will say, the soil has to be moist for the other meters to work. Obviously the light meter will read, but if you have a dry plant, it will not be able to read the pH and nutrient levels. But I very much recommend it, it seems very durable, so much nicer than any I’ve had in the past, and like I said, I love it has the nutrient reading.

This is the first meter of this sort that I have ever used and overall I'm happy with it. The solar portion seems to be spot on and I get what I feel are accurate readings on moisture and nutrients. That being said I do have to jiggle it a bit to get it to give me those moisture and nutrient readings. As a novice with these I'm not sure if I should be doing that or not. Nevertheless I do use it every single day to guide me and double check my gut feel that I think is improving with practice. The ph meter is the most problematic for me. I have never seen it move off of being completely pegged out to the left. I find it hard to believe that I haven't managed to achieve some ph balance in any plant so far so I can only assume that it isn't functioning properly. For the price and what the instrument does do for me, I think it was a good purchase.

Discovered my back yard needed fertilizer and once I got it everything bloomed and veggies grew gast. Very pleased. Helps diagnose what your garden needs to flourish.

UPDATE: The pH metering stopping giving me readings. I used in the Fall and it stopped working in Spring. I sanded it per instructions but didn't help. Customer service quickly got back to me and sent a replacement with some extra hints. I think I might have messed it up because you are only supposed to lightly sand the lowest piece of the probe - the tip - but I had lightly sanded the length of the probe. The extra instructions they sent said this - so save your sandpaper and don't overdo it like me and you should be able to enjoy using it for multiple seasons. ---- The meter does produce different results for different soils around the yard. I mainly wanted the pH part, the other stuff isn't super necessary for my needs but interesting nonetheless. The pH seems like it could be pretty correct as it does adjust slightly for soils I know are more acidic (due to the type of fertilizers I use.) My problem is that the range of pH anyone really needs for soil is liberally only between 4.5 - 8.5. If you have soil below or above these it really doesn't matter how much since it is so far off the chart of what is needed for anything other than highly specialized growing media. And if you were doing that you would have more sophisticated equipment. So the entire range of what I care about takes up very little space between 1 and 8 since everything I have is between 5.5 and 7.0 pH. It's impossible to see at this scale if you are at 5.8 or 6.2 or what. You just have a rough approximation that it is about 6 which isn't super helpful. Every 0.1 change in pH represents a 26% difference in acidity or alkalinity of the soil. This instrument should be fine tuned for a smaller range of the pH scale showing at least .5 unit steps. An annoyance is that the needle at rest, in no soil medium, is pretty much right over the 6.5/7 pH scale. So if you insert the probe into soil that is 6.5 the needle doesn't move causing you to think it doesn't work. Every time this happened to me I flipped the switch around and would see the needle react very quickly and so I know it was functioning but the resting needle should really have its own place as is the standard on almost every other instrument you can find. The probe itself seems well constructed. I pushed it deep into the ground and was able to pull it out pretty easily. I think if you put too much pressure on the meter head while pushing it in you might break it though. The box comes with a little square of sand paper you should not throw away. Eventually the probe will lose its measuring abilities from a little corrosion build up on the metal. A light sanding would refresh it.

This is a simple way to make sure that you are watering correctly. It seems to be accurate on the ph meter.

It's inexpensive however is inaccurate from what I have seen.

I purchased a meter because it has a swivel head and I thought it would really be nice to know the alkalinity and acidity. I am very disappointed that the alkalinity / acidity function does nothing. I tested it on potting soil that was rich nutrients and also in straight sand the meter reading didn't change both read the lowest alkalinity. I know sand is not alkaline it is acidic. I'm going to keep it only because I like the swivel head and the moisture reading seems to be accurate.

China scam product, does not work.

Producto de Excelente Calidad

للاسف المنتج سيء جدا ولايعمل حاولت كثيراً مع المؤشر ولكنه لايتحرك باي طريقه اشعر بالاحباط والخداع لن اشتري من هذا البائع مره اخرى وسااخبر اصدقائي المزارعين بذلك

Plant water meter. Works well. Good buy.

Best thing I had bought for my house plants and garden,so, I am not over watering them.
