Sonkir Soil Moisture Tester Gardening Cover
11.5 x 2 x 1.5 inches
2.39 ounces

Received meter today. Went right out and gave it a try. Problem number one, which isn't a flaw of the instrument, is it measures LUX, 1 candle placed one meter above an area 1 meter square. In other words, a candle power.

Not a great deal of use in trying to figure out how much light my plants need at various stages. (I knew this going in, so this isn't a bitch, just an admission that I didn't think things though before purchase) Finally found measuring PAR would be better, and that confused mr no end.

Any way, I found out with my trial run, that measures Ph accurately. The moisture, I am not to sure of. It measured three plants that I thought dry as wet, but one I knew to be dry it measured as dry.

Also, determined that the 10 minute wait period is necessary for the meter to calibrate itself. The immediate measure of moisture was past the 10 on the scale. Ten minutes later it had dropped to 8 on the moisture scale. That has to be done at each plants location.

Xlux Soil Moisture Sensor Meter Cover
10.43 x 1.18 x 2.17 inches

So far I'm very pleased with this product. I think that the few negative comments have been made by people who don't understand the science of sampling and data collection. They don't realize that with any device used for measurements, there will always be a sampling error.

They think if the device doesn't record the same result every time then there's a problem with the machine. Yes, you can place the probe into soil at different locations in the same pot or garden area and it may record slightly different readings, say maybe 6 at one spot and 6.5 at another.

But for the price of this device, it is very accurate. Also, many comments were made that they inserted the probe into a glass of water and it didn't read "wet", when the instructions clearly say not to do this.

There were comments made about the probe being a weak spot in the device, and would break off.Yeah.... If you try to use this as a pick axe or a fence post. You're not supposed to beat it into the ground with a sledge hammer.

This product does exactly what it says it does!Efficiently too! This product is 3 bottles pH-up, pH-down and a pH test solution. (also comes with a vial to conduct the pH testing in AND a pipette which I thought was great, I ended up getting on before I opened the package assuming they did not provide one, but General Hydroponics really gives you everything you need to open the package and do testing RIGHT AWAY!

I tested this on my hydroponic system with a calibrated pH meter hehe..... I wanted to know how accurate the test solution is. The test solution runs on a color scale, acidic being pink basic being dark green. The scale is located ON THE BOTTLE!

So you never will lose it. As far as my basic testing concluded, the test solution is accurate; the color changes are visibly recognizable and comparable to the provided scale.6.0 is yellow, 7. 0 is green, and both of these matched my pH meter (in approximation, don't expect to perfectly get a 6.

This is exactly like the one I bought at a big box store many years ago, except that it was black plastic and did not have a brand name on the meter. In every other respect they were identical in every detail.

When my old one finally gave up the ghost this Fall I bought this one to replace it. I noticed several other listings on Amazon that look the same except for the name on the front of the meter. I was very happy with my old one and this new one as well.

It is important to know whether plants are getting enough moisture. Different plants need different amounts. The package contained a listing of a number of plants and their requirements. Sometimes after a heavy rain the ground is saturated for a period of time even when the surface is dry.

If you water too Mich you can cause the roots,to rot, and,then the plant dies. With the probe you are checking the moisture content below,the surface.

Worthless junk.PH reads the same no matter what soil you place it in? Flip the switch to moisture while in the same soil and readings do not change? Only 1 of the 3 that seem to read correctly is the light meter.

Sadly the only one of the 3 I did not need. I bought this to measure PH for the different plants separated out in my elevated 10 X 10 garden. All of the separated portions read the same. Which it starts out between 7 to 8 on the scale.

And does not vary no matter what soil you check. Maybe just a bad unit? Should have gone the extra money for a working PH tester. As I NEED to see the real PH balance in each of my different plant types.

Tjhey all can not be 7. 2 in every container or every part of my yard which also all read the same.....Update.7 3 19. Customer service for this seller is awesome. After having a bad experience with the 1st product. I just posted a review and threw it in a junk drawer.

I laid new Bermuda grass in April and put new soil and tall fescue just two weeks ago. The flowers I've planted in the flower beds along the way. One has succeeded and the other has been a garden of death and that was the reason for buying this soil tester.

I want to show everyone what I received out of the box. I got home and went straight to the yard because my sprinkler system had just watered and the soil was loose. I have a small screwdriver that I initially used to make the holes to insert the probes.

I soon found they were not as fragile as people claim and only had to use it in a couple areas. But, I do recommend using the screwdriver method in case you have rocky or clay lawns. You have to use common sense.

If it doesn't slide smoothly into the ground, why force it in. As for the rest, the pictures I uploaded speak for themselves. Every area was a little bit different and most importantly, I got a great overall picture of what is happening with my lawn and garden areas.

Vivosun Moisture Outdoor Promote Healthy Cover

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...

Dr Meter Moisture Hygrometer Outdoor S10 Cover
13 x 4 x 1.6 inches
2.72 ounces

At first I wasn't sure if it worked or not, testing it in the dozen potted fuchsias I'm overwintering in my garage under lights. The reading varied from 2 to 3. 5 in each pot however, so I figured it is measuring something.

Then I added 1/4-1/3 C water to each pot and saw almost no change in the meter readings. I took it outside and stuck it into the moist ground in my back yard-same result, right around 3. I stuck it in a glass of water and it read dry, so it occurred to me that it's measuring something that's not present in pure water, perhaps ions that are only present in soil.

Finally I went back to the fuchsias and pushed the tip all the way down to the bottom of the pot-the meter read 6-7 in a few of the pots, but still 3.5 in one of them. The answer was obvious-the water had gone directly to the bottom of the pot, not to the roots, which were mostly still in the middle portion of the pot, due to being recently repotted.

Outstanding product and service. I have both an old lawn in pretty rough shape and an area that I am putting in a new lawn. I decided to get 2 kits one for each area. Before I bought the product on Amazon I called the My Soil company at the number Amazon provided for them.

The whole process could not have been simpler! In total it took 10 days from the time I ordered the kits on Amazon till I got the results online from My Soil.

As they come from the factory, these (at least the two I got) seem to only be good for desert plants (cacti & succulents) that need to be totally bone dry before watering. First let me debunk a couple of reviews I read that said these were 'crap' because when the customer put them in a glass of water they read 'dry'. They are NOT made to read the presence of PURE water!

They only take a reading on water that has impurities. I got some clean pure water, stuck the probe in it and it read 'dry'. I then boiled the water and made a cup of strong black coffee, and a cup of strong black 'Earl Gray' tea;stuck the probe in each one of those and the meter pegged over to a 10++ reading.

If you get a pot of good soil, and soak it well with water until it's dripping out of the bottom of the pot (waiting until all water dripping stops first) and then stick it in the dirt, it also reads 10++.

This moisture meter works just fine. For all the reviewers who stuck this moisture meter in water and claimed it was junk because it read "dry"-(*facepalm) that's not how moisture meters work! Such devices are designed to measure the electrical conductivity in soil, not the "wetness" of water.

I haven't ever met a moisture meter that would read water. For those who said that they just watered their plant and it still read dry... I would wait a good hour and test again. Depending on the type of soil (many types are quite hydrophobic, especially when bone dry), it takes a while for the soil particles to absorb the water.

Sometimes seeing the water draining from the bottom is not enough. It can run right through if the soil is bone dry. Let it sit and water again after 30 mins. Then wait a while and test again. Another possibility on that one would be that the soil was so saturated with standing water, the meter could not read the soil because it only had contact with water (similar to what happens when you place the meter in a glass of water).Anyhow...

Soil Test Kits Buying Guide


Everyone differs in budget as well as the product features and prices. It is a good way to go for a pricey one if you are looking for the highest value. It is advisable to opt for high quality when choosing a soil test kit. In general cases you get what you pay for. That does not mean higher cost equals to better quality. Nevertheless, you are possible to get an affordable one with effective cost. Checking reviews of the options is another way to narrow down your choice.


Soil test kits provide details of the soil but not all models deliver full information. The most common data includes light exposure, moisture content, PH, temperature, and nutrients. Some models can cover all the data while some only present a few points. You have to choose the information as you need. The light exposure tells how much light a certain spot in the garden receives. That determines whether it can host some sunlight-liking plants in the area. Moisture content helps to avoid overwatering or under-watering. A balanced PH around 7 ensures the soil can absorb the nutrients. The nutrients content indicates what the soil needs. Adding fertilizer without knowing the nutrients might cause adverse impacts.


When testing the soil, most do not need to know the exact PH level of the soil. The soil test kits tend to be accurate on a rough grade of the soil including basic, neutral or acidic. Choose a probe with higher accuracy if you want detail PH. It is vital to get accurate NPK data and how much of each nutrient is in the soil. What level of accuracy you want depends on what you will use the data for. Famers tend to care more about the accurate details of the soil that they usually require high accuracy.


The soil test kits vary widely in the functions and features. The digital models present PH levels while chemical kits present the macronutrients. There are plenty of models to measure light, moisture, temperature and so on. You have to know what you use it for and what is your expectation before making a choice. When you are doing a professional sample test, it gives comprehensive data. But it takes longer to get the results. You have to evaluate your needs accordingly before choosing the right type of soil rest kits.

FAQs on Soil Test Kits

Unless you are growing grass, your soil is pretty useless. Fruits and vegetables need amended soil. That's why the big box stores sell garden soil, potting soil, compost, mulch etc. By the time you get your soil ready for real plants, your dirt will not need to be tested because you know what you put down.

So, I don't know if they are accurate, but I do know they are useless. Spend your money on a soil thermometer instead.

Sil testing kits are ok for testing and reading p, H of the soil to determine if you need to add lime. But if you want a good soil test run, send to the land grant university lab through your local Extension Office.

The are generally cheaper and very helpful.

FirstWhat are your concerns? If this is farm land then you may be interested in the fertility of the soil which can be tested by any reputable facility. However, if there are concerns about some type of pollution then more extensive examination should be done by an environmental engineering laboratory that specializes in testing for contaminants.

SecondThere are natural treatments of the soil that can help eliminate, or at least, reduce the level of residual pesticides, herbicides, etc.In the soil. Apply the best compost that you can afford wherever you intend to grow fruits and vegetables.

You may begin with spraying the soil with a molasses solution to encourage beneficial bacteria in the soil.

I am a student and as for testing soil analysis we used Niton XRF sprectrometer which at that time needed calibration and would say that it was not correct but its data can be used as reference for at least to know what the soil lack of, has enough.

For this type of analysis you have to do more repetition of analsis but it gives you a nice results. Photoelectric photometry (flame) i would say that is an important tool to use to determine the soil nutrient availability of soil and their amount in the soil.

And another one that i worked i gave correct result i would say is the case of chemical soil analysis kits which i used in laboratory were correct. It has its own protocols, in case you want correct result you have to be precise to follow the rules in there.

These three are kind of some that i know how its done the job. But actually i always had the results which now i understand that i did not do the interpreting' of data. I think that is important to be clear when do prepare the samples and to stay on track of the work.
