Vermiculite is a mineral with a laminated structure that is mixed with the substrate or applied on the surface to maintain the temperature and humidity during germination.

Vermiculite is used in hydroponic systems and with the use of this mineral you can maintain the humidity of the substrate in a more optimal way.

The amount of vermiculite that you add to the substrate should never exceed 5% of the total of the pot, since, if you exceed this amount, it is possible that problems of excess humidity in the substrate may appear.

Why Should we use vermiculite?

The action of vermiculite is very similar to that of expanded clay, but vermiculite retains more water, since it can retain up to 5 times its weight.
