Blumat Digital Moisture Meter (20 CM) & Protection Cap

A super accurate way to know the moisture level near your roots. Often the moisture near the surface where you can feel is fine while the soil near the roots is dry as dust - or the reverse: dry at the surface and over-watered at the roots. Seasonal differences can cause these conditions to rapidly reverse. With this Blumat Digital Sensor, you won't have to guess! You'll know exactly if your plants need water or not.

Comes in clear tube with precise instructions and number readings that apply for different seasons and different kinds of plants.

It works in a similar way to the Tropf-Blumat but it does not control watering. It measures the levels of moisture and/ or dryness. It operates using the tensiometer principle and indicates the amount of force necessary for a plant to absorb water.

This method of measurement allows for very accurate recognition of the level of moisture near the roots and therefore, a more exact application of water - whether by hand in large container plantings. For example, when over- wintering plants, it's very important to keep a moderate moisture level - sometimes harder than watching for this during the growing season. And of course in the summer for monitoring and adjusting your watering schedules. Knowing the moisture level in large containers is no longer a matter guesswork and experience, but rather of concrete numerical data.

The lower the number readings, the more wet the soil. On average, the standard Blumat setting of two arrows down from a drop holding = 120 mb. (Ideal settings for cannabis growing = 120-150 mb in veg, 150-180 in bloom). The higher the reading, the more dry.
