Vermiculite, agrivermiculite 1/3 mm (pallet of 36 100 l bags)

VERMICULITE, AGRIVERMICULITE 1/3 mm (pallet of 36 100 lt bags).

For the production of Vermiculite, only vermiculite with very high levels of purity is used, extracted entirely from the Palabora deposits in South Africa.

The thermal process to which it is subjected gives rise to a lightweight expanded material, free from pollutants (heavy metals).

The particular treatment gives the product a porosity of approximately 95% by volume, a water retention capacity of 54% and a thermal conductivity coefficient k of 0.049 cal/hm °C.

Thanks to these values, the distribution of Germisol F over the sown containers allows a reduction in water evaporation, a delayed drying of the substrate, thermal insulation and a reduction in the frequency of wetting.

All to create a microclimate favorable for seed germination.
