The XLUX Soil Moisture Meter is designed to help gardeners know the moisture level deep inside the soil, which is more reliable than just feeling the surface. It features a large, easy-to-read dial with clear zones indicating dry, moist, or wet soil. The meter gives instant readings when you insert its single probe into the soil, making it very straightforward to decide if your plants need watering.

This product doesn’t require batteries, which means it’s always ready to use and lightweight to carry around. The single probe design is gentle on plant roots and reduces soil disturbance compared to meters with multiple probes. However, it’s important not to leave the probe in the soil for too long to avoid corrosion, and it’s not suitable for testing very hard soil or liquids other than soil moisture.

Since the meter measures moisture but not light, it is not suitable for those specifically wanting a light meter for gardening. For gardeners focused on soil moisture monitoring, this tool is affordable, simple, and effective, but if you need a device to measure how much light your plants are getting, you'll want a dedicated light meter instead.

Accuracy
Sensor Type
Display Type

Most important from
1404 reviews

Accuracy
Provides clear and reliable readings for soil moisture, pH, and sunlight, making it easy to monitor garden conditions accurately.
Sensor Type
The large probe length is ideal for garden beds but may be less suited for smaller pots.
Display Type
Displays data instantly and clearly, eliminating guesswork and helping prevent overwatering.

This 4-in-1 soil and light meter is designed for gardeners who want a handy tool to check not only sunlight intensity but also soil pH, moisture, and temperature. It uses updated sensor technology from 2024, which helps it deliver fairly accurate and quick readings. The large green backlit LCD screen is a big plus, making the data easy to read both day and night, especially for users who might struggle with small or unclear displays.

Since it measures four important factors for plant health, it’s especially useful for people growing a variety of indoor or outdoor plants, as well as for garden and farm care. The probe needs to be inserted about 3-5 inches into the soil, which is easy to do but requires caution with hard, dry soil to avoid damage. It’s quite lightweight and portable, so you can carry it around the garden comfortably. However, the product runs on three AAA batteries (not included), and some users may find it inconvenient to replace or worry about battery life, although it does warn when batteries are low.

Durability-wise, it’s made with standard materials and should hold up well if used carefully, but pushing the probe into tough soil can risk damage. Its accuracy is good for casual to intermediate gardening needs but may not satisfy professional growers needing lab-grade precision. This meter serves as a practical, user-friendly choice for most gardeners who want to monitor multiple soil and light conditions with one device, though users should handle it gently and be prepared to manage battery replacement.

Buying Guide for the Best Light Meter For Gardening

Choosing the right light meter for gardening can significantly impact the health and growth of your plants. A light meter helps you measure the amount of light your plants are receiving, ensuring they get the optimal light conditions for their growth. When selecting a light meter, consider the following key specifications to find the best fit for your gardening needs.
Light RangeThe light range of a meter indicates the spectrum of light intensity it can measure. This is important because different plants require different light intensities. Light meters typically measure in lux or foot-candles. For low-light plants, a range of 0-10,000 lux might be sufficient, while high-light plants may need a meter that can measure up to 100,000 lux or more. Choose a light meter with a range that matches the light requirements of your plants.
AccuracyAccuracy refers to how close the meter's readings are to the actual light intensity. This is crucial for ensuring your plants receive the right amount of light. Accuracy is usually expressed as a percentage. Higher accuracy meters (within ±5%) are better for precise gardening needs, while slightly less accurate meters (within ±10%) may be sufficient for general use. Consider how critical precise light measurement is for your gardening setup when choosing the accuracy level.
Display TypeThe display type of a light meter can affect how easily you can read and interpret the measurements. Common display types include analog and digital. Digital displays are generally easier to read and can show more precise measurements, while analog displays might be more durable and simpler. If you prefer quick and clear readings, a digital display might be the best choice. However, if you value simplicity and durability, an analog display could be more suitable.
Sensor TypeLight meters come with different types of sensors, such as silicon photodiodes or selenium cells. Silicon photodiodes are more common and provide accurate readings across a wide range of light intensities. Selenium cells are less common but do not require a power source. If you need a reliable and versatile meter, opt for one with a silicon photodiode sensor. If you prefer a meter that doesn't need batteries, a selenium cell sensor might be the way to go.
PortabilityPortability refers to how easy it is to carry and use the light meter in different locations. This is important if you have a large garden or multiple growing areas. Compact and lightweight meters are easier to move around and use in various spots. If you need to measure light in different parts of your garden frequently, choose a portable light meter. If your measurements are mostly in a fixed location, portability might be less of a concern.
DurabilityDurability indicates how well the light meter can withstand regular use and exposure to gardening conditions. This is important for ensuring the longevity of the device. Look for meters with sturdy construction and water-resistant features if you plan to use them outdoors. If your gardening involves a lot of outdoor work or you tend to be rough with tools, a more durable light meter will be beneficial. For indoor gardening, durability might be less critical.
