What to Look For in a Good Soil Meter
As said, all the tools that make your gardening easy and more enjoyable are welcome in your toolbox, but you have to agree that the soil meter is one of the most important, if not the most important, tool of all. With a variety of choices on the market, it’s important to have a few directions before deciding which one to buy. You should keep in mind these essential features:
The model you choose can be only moisture meter or only PH level meter, but it’s always better having one device that’s multifunctional than having three different devices. Having only one device saves you money and space, and it’s convenient for carrying around. That’s why you should consider buying a 3 in 1 meter that will offer you a complete analysis of the soil.
2. Durable material
You want to be able to use this device in years to come. High-quality, sturdy material will make that possible. Probes are fragile in general so try to find a device with the least fragile sensors for longer use. A nice choice would be buying a device that is water and dustproof.
The majority of people aren’t professionals, and complicated devices would only make gardening harder. That’s why the display and controls on the meter should be intuitive and easy to use even if it’s your first time using a soil meter.
If you want to be sure your soil and plants are treated right, the meter has to be accurate and always show the right amount of moisture, sunlight, and PH level. Even the slightest imprecision can be deadly for the sensitive plants in your garden. This is especially important when it comes to measuring the moisture of the soil since it’s very easy to over/under water the plants.
If you’re searching for something that can be used indoors, go for a small and compact device that can fit your plant pots. This will also be convenient to use outdoors, especially if you choose a model that doesn’t require electricity or batteries.
