One of the great problems of inside plants is the irrigation. It is common for people to over water, failing to read the needs of the plant and wetting it more than necessary.
Remember that being indoors, water takes longer to evaporate in indoor plants even when the earth looks dry in its surface layer. The biggest risk of overwatering is that the plants become waterlogged and their roots rot. Fungi that are attracted to damp conditions can also appear.
What is a hydrometer
To avoid overwatering, some find a solution in the hydrometers, some manual devices that must be placed on the ground and take care of de measure soil moisture levels through a needle.
These humidity sensors They can be used for this purpose, although they also have some limitations, so before buying one it is best to know if they really provide valuable information.

Some experts claim that lhydrometers are not reliable for the ideal humidity level it depends not only on the land itself but it is also related to the species, taking into account that some need a more humid habitat than others to live in optimal conditions.
In addition, it is known that a clinical eye is worth more than an apparatus and this is how when you have experience it is not necessary to resort to a hydrometer since it is enough to remove the surface layer of the earth to verify its general condition. Or you can see what the grass looks like: if you notice that the ground is very dry and that the grass flattens when stepped on and does not recover, it is time to water.
Despite what has been explained, a hydrometer is a lifesaver that is still useful in the case of beginners. If they want control lawn watering You can use it because just by pricking the grass you will get information about the humidity level of the soil, you can even repeat the operation when watering in order to suspend watering when the optimum level is reached.
