The present invention makes it possible to visualize the drying of soil to a desired degree and notify a user of this drying.

As for the drying of the soil, there are several solutions to this problem.

When drying the soil, abundant watering is carried out, allowing the soil to be saturated with water by about 50 cm.

This causes the soil’s premature collapse, thus increasing the soil’s drying time and slowing the growth of your bonsai.

During growth, flowering and as the soil dries, swimsuits need to be watered.

At the same time it is impossible to allow both waterlogging and drying of the ground.

Bortics, together with the step, first primed, and after the drying of the soil, waterproofing works are carried out.

Fertilizer or nutrients can accelerate the soil’s drying time by affecting the speed of a bonsai tree will grow.

A decrease in the drying rate of the solvent increases the initial release rate of the drug and an increase in the drying rate of the solvent decreases the initial release rate of the drug.

So, if usually irrigation was carried out as the soil dries, then a blooming orchid should be watered abundantly every 3-4 days.
