Pearlite

BENEFITS OF PERLITE:

• Ideal for achieving mixtures with good aeration

• Improves drainage

• Retains moisture

• Inert

• 100% Natural and friendly to the environment

• Incorporate perlite so that it represents between 10% -50% of the total volume of the final substrate.

• Planting in substrates with a high proportion of perlite requires greater addition of fertilizers during all phases of growth.

• Planting in substrates with a low proportion of perlite, provides greater retention of water and nutrients, therefore requiring less addition of fertilizers in all phases of growth.

• It is recommended to mix with  Coconut fiber  and  Compost Premium  by BioTerra

* You don't know how much perlite to use?  Look for the  Potting mix  I the  Bio-Substrate  that were specially developed to provide growth in groves, pots and beds.
