at 40c / test u cant go wrong - very accurate!
Did exactly as described (its like primary school science!). Tested soil here where we live in San Pedro California. Only took one sample as Im planning to seed princess (Hybrid bermuda) in the nest 2 weeks.The kits works great! As stated you really need to use indirect but good sunlight for best results. Tilting the tank a little (as shown in the pic) helped me match the color better than looking straight onto the chart.This pic was taken after it stood overnight - the more the dust/particles settle after shaking the better color comparison u can make - its clearer.I held it up against our wood fence to remove distracting background colors -Very happy and I have 9 samples left for 4 bucks - win win! Lucky we have a neutral to slightly alkaline soil!

5.0 out of 5 stars Quick, Simple, Reliable. Provides a general Idea of soil pH based on color comparison.

I bought this to test the pH of my blueberry soil that I have in half wine barrels. I used 1/3 pine bark mulch, 1/3 sphagnum peat moss, and 1/3 organic potting soil. I mixed it all up well and checked the pH a few weeks later. This quick little kit gave me indication I was at around a 6. I wanted to drop it a bit further so I added some organic acid fertilizer, waited close to 2 months and rechecked. My soil is now around 4.5 to 5. The blueberry bushes love it and they are green (not red and yellow now), growing fast, and have tons of flowers!

+ Water Dropper Included
+ Simple Instructions
+ No Mess
+ Consistent Results
+ Takes about 2-3 minutes to take a sample and get a reading
+ Small Booklet providing details of many different plants, vegetables, and flowers and the soil pH they grow best in

_Bottom Line_ Yes, I would recommend this pH kit over other products, such as a soil probe. In my experience this is the fastest, most consistent, easiest way to get an accurate idea of what the pH is. This kit really helped me get my blueberry bushes up and going and I will continue to use the test kit to monitor my soil pH.

Kit includes10 separate PH test capsules; purchase this and can perform 10 separate tests.

Easy to use nice little vial to place in sample soil, PH capsule contents, and water. shake around and wait a bit. Hold up to sunlight but not direct sun (important).

PH tests are inherently somewhat difficult to interpret. Is it this shade or is it the next over shade. This kit cant fix that. But this kit is easy to use and reliable if instructions are properly followed, especially the light source.

5.0 out of 5 stars So easy to use!
Reviewed in the United States on June 15, 2012

I had never tested my own soil before and had wanted to, but the tests seemed so complicated and hard to use. After looking through the soil testers on Amazon I thought I would take the plunge and do my own testing. Well, it was a lot easier than I thought and the results are easy to read and are accurate.

My neighbor has a larger, more expensive kit and he did a test right after I did mine and they were pretty close to each other with the results. I could not be happier with the kit and I found out exactly what I needed for my garden. The best part of the Luster Leaf kit is the price. So inexpensive and such a great result!

4.0 out of 5 stars Soil PH Test Kit for the Nimble
Reviewed in the United States on December 23, 2023

The test cavity is small and results vary with the moisture of the soil.
I got an easy to read test color with dry soil and moist soil came out
black as the color of the sample. The readable sample came out at
about a 6 so as a precaution I spread one coat of lime. We'll see how
things turn out in the spring. The test powder lozenges do not separate
easily. The smaller ID half crushes with little pressure trapping the powder
and spilling out some on separation. I have no idea what less than a full
lozenge does to the accuracy of the test. All of this does not build a lot of confidence
in result efficacy.

5.0 out of 5 stars Don't throw money away on fertilizer
Reviewed in the United States on February 6, 2012
Verified Purchase
I grew up on a farm and I've been gardening for over 50 years. When I was a child, we took soil samples to our county agent every few years and guessed during the years between samples. That was not often enough for NKP or PH. The County Agent's report covered 6 or 8 more things such as borax, aluminum, and calcium. Those things change very slowly and only need to be tested for only every 5 to 10 years. In the fifties and sixties, we just assumed the soil would need lime each year; it was acid. However, the amount we used was calculated by rule of thumb. Others used the taste test; tasting the soil to tell if it was sweet or sour; better than nothing but very distasteful when the fertilizer of choice is manure.

If you do no other tests, do this one! PH controls whether or not a plant can take up nutrients. All the fertilizer in the world will not help, if the PH is wrong. I purchased the full test set as well as this one so that I could do more frequent PH tests and in more places such as around shrubs, bushes, and trees, especially fruiting trees and bushes. I have been using these products for at least 20 years. This purchase was just to renew my supply. I can usually go 2 or3 years with a full Luster Leaf set plus an extra PH test set. Buy and use it!. It will save you money on fertilizer and you can have the best garden in the neighborhood!

3.0 out of 5 stars Worked OK, with modified instructions
Reviewed in the United States on February 21, 2014

I tried following the instructions - put soil in the tube to the first line, add the indicator powder, fill to the second line with water, put the cover on and shake, then read the color - but it was too muddy to compare the color to the chart (there's a lot of clay in the soil in my area). So I modified the instructions: I measured the lines on the tube to get the proportions of soil to water, marked a clean clear glass jar with two lines in the same proportions (e.g., 3/16" on the tube = 3/4" on the jar, etc.), then put dirt in the jar to the first line on the jar, water to the second line, shook it thoroughly and let it settle for an hour or so. Then I decanted some of the now-clearer water above the settled dirt and filled the kit tube to the second line, added the indicator powder, put on the cap and shook to dissolve the powder, and found it was easier to read the color. I reasoned that the acid and base components of the soil would be water soluble and stay in the leachate above the soil in the jar, giving an accurate pH color reading without the mud interfering with the indicator color, but I'm not a soil chemist, so take all this with that in mind.
