Garden Soil pH, Humidity and Incident Light Metre

Product detailed description

Get a clear picture of the conditions in which you grow with this 3-in-1 multifunctional soil metre. Use this metre to quickly and easily check three key parameters for healthy plant growth.

Key features in one device

• Humidity measurement: Find out instantly when it is time to water. This helps you avoid common mistakes such as overwatering or drying out the root ball, which can cause irreversible damage to plants.
• pH measurement: Get an approximate idea of how acidic or alkaline your soil is. The right pH value is essential for effective nutrient uptake by plants.
• Light measurement: Check whether your plants have enough light for photosynthesis. Ideal for choosing the right place for plants indoors or in the garden.

How to use the metre

It is very intuitive to use and suitable for everyone. A major advantage is that no batteries are needed. The device works on the principle of a galvanic cell, which is activated by contact with moist soil.

1. Use the switch on the device to select the parameter you want to measure (MOIST/humidity, LIGHT/light, or pH).
2. Carefully insert the probes into moist soil near the plant, to approximately two-thirds of their length (following the instructions provided).
3. Read the value on the analogue dial. For a more accurate pH reading, wait 5–10 minutes as instructed.
4. Clean and dry the probes carefully after each use to ensure the longest possible lifespan and accuracy.

Who is the metre for?

This metre is an ideal tool for a wide range of users. It is suitable for both beginner growers of houseplants and experienced gardeners. It is great for caring for annual herbs, fruiting vegetables such as tomatoes and peppers, ornamental flowers, as well as checking lawns and much more.

Important information for correct use

We want to be transparent, so it is important to know that this is a hobby-grade metre for approximate readings. While humidity and light measurements are reliable for everyday needs, pH readings should be treated as indicative. For precise laboratory results, we recommend using calibrated digital pH metres. Handle the probes carefully; they are not designed to be pushed into very hard, dry or stony soil.

This soil metre provides valuable data to help you better understand your plants’ needs. It is a simple but effective way to grow healthier plants and enjoy a more abundant harvest. Our guide Soil pH: how to identify, measure and adjust it explains how to measure and adjust soil pH correctly.
