Luster Leaf 1625 Digital Soil Thermometer

The media could not be loaded. i started growing a bonsai on 12/25/2023 and when i read the instructions, it said the soil had to be a specific temp. and when i tell you it took me like a solid hour to find this, im not kidding, this is the only one i could find. and thank god i did because this is surprisingly cheap for the quality. now i'm not sure how accurate it is since i have no other way to test it, but it's been helping my keep my tree growing and alive and beautiful, so i'd say it's fairly accurate. it's pretty long so it can test pretty deep into a lot of pots, but it can also take the temp from the very tip is you have smaller pots. its super easy to use, literally all you have to do is press a button. i've had this for about a year now and it's help up great, its super durable. it's also pretty bright and easy to read. i'm so happy this was made because i literally couldn't find anything else so thank you makers(trust you should buy this) oh it's also super fast. i just wish it had some sort of feature like a normal thermometer that beeps or something to show it's done taking the soils temp. but it's a great product

I have their pH gauge, which is sketchy at best, until I can verify its accuracy, but this thermometer works well. I use it for soil temps in order to time the planting of garden vegetable seeds. It’s accurate and gives a good reading within a few seconds of sitting in the soil. None of their gauges are very easy to read. You need to remember to insert them at a steep angle so you can see the numbers easily and clearly. The display is not illuminated at all, so getting the correct light balance in order to read the numbers is a hassle. But it isn’t a dealbreaker. It’s priced decently and does the job.

I am a golf course superintendent. I use this to take soil temps to determine when to spray certain chemicals such as pre-emergent crabgrass herbicides. This little guy is easier to read than most soil thermometers. Give it about 10 seconds to stabilize and record your temp. Consistent with other soil thermometers I have used. For the price its a great buy.Only negative would be that it feels a little flimsy. The plastic shell that holds the components isn't the most rugged but if you take care of it it should last a while.

Happy this works good for monitoring my seedlings and plants while I have them on a heating pad.

It took me a whiles but I finally figured out why both my thermometers always - always! - showed 65 degrees. The vendor pastes a little clear piece of plastic on the read-out window, is why. The instructions give you no warning. Geesh.

Received product in a timely manner - 8/14Tested the thermometer in several window beds, and found very accurate readings.From air to soil the needle was extremely sensitive to the temperature change. Currently we are in the middle of August and the weather is quite warm. My soil is a few degrees cooler than the air. I immediately saw a temperature raise when I pulled the needle from the soil.At $15 I would recommend this product to all home gardeners.As always with these kinds of instruments "Care and Cleaning" is a must to maintain a good product. If you read other reviews with negative remarks - then please keep in mind how one handles a product will reflect it's performance.

Worked perfectly the first two times. Quick read and seemed to be accurate. It broke on the third day. As I pressed it into the ground, the shaft retracted into the thermometer unit and immediately stopped reading the temp. Everything inside just fell apart. It was cheap. What do you expect? Don't buy unless you're going to be measuring the temperature of soft potting soil. I'll just buy another product.

I have 700lbs of Combat Extreme grass seed sitting on a pallet that is totally dependent on soil temperature and when I plant. This soil thermometer, as I test the rising temps, has given me accurate and steadily climbing temp readings. This tells me of its quality. Its not 50* degrees one day and then 47* then 51*. It has been 48*, 49*, 50* and so forth as the ground warms. (55* degrees is my minimum target temperature.) I have thousands of dollars and a year's prep time resting on the success of my planting and the Luster Leaf thermometer has given me the confidence I need to plant right when the ground is ready!
