We write about all sorts of interesting aspects related to plant nutrition and health!

Buffer

Buffer

All kinds of mistakes can be made during fertilization. The main error is the imbalance, by unilaterally adding an excess of certain ions (salts).
Carbon dioxide CO2

Carbon dioxide CO2

In the air, the carbon occurs as carbon dioxide (CO2). It is brought into the air by breathing plants and animals and by decaying or burning organic substances.
EC value

EC value

EC stands for Electric Conductivy (mS / liter) and with that we measure the amount of (usable and unusable) salts in water.
Growing temperature / energy

Growing temperature / energy

The culture temperature is a very important determining factor. If the growing temperature is not correct, the plant will grow less or not at all.
Humidity

Humidity

Humidity is perhaps the most underrated growth factor. We use relative humidity RL as a unit to measure this and to make adjustments.
Light / Dark / Hormones

Light / Dark / Hormones

The relationship between light and dark (day and night) is what we call the photo period. Flowering starts when the days get shorter.
PH value

PH value

he pH of a medium is a very important, but also the most wrong factor. A plant transports the elements in water.
Rhizobacteria and Trichoderma

Rhizobacteria and Trichoderma

With the help of soil life, plants can build up a healthy and natural resistance to diseases and attacks. We can distinguish bacteria into bad bacteria and good bacteria called the Rhizobacteria.
Spraying plants

Spraying

Plants usually fail to absorb fertilizer through their leaves, but it is still common for experts in agriculture and horticulture to use spraying methods. Why do they do it?
Plant nutrition

The new generation plant fertilizers

Metrop Hydroponics' new line of highly concentrated organic fluid fertilizers can rightly be called the new generation of organic plant fertilizers.
Growing Plants

Growing Plants

The most phosphorus in a plant or tree is in the root !The higher the phosphorus level in a growth fertilizer, the greater root growth ! That is why Metrop made the MR1 Grow fertilizer.
Flower fertilizer MR2

Flower fertilizer

The Metrop MR2 is a very high concentrated liquid Flower fertilizer. Maximum use is 100ml in a 100 litre water tank. That means you dont have to carry large bottles of fertilizers anymore.
Foliar Feeding

Foliar feeding

Nutrients can’t normally be taken in through the leaves or fruit. Still, we spray a lot in professional agriculture and horticulture markets. How can this be?
