perlite
 
Expanded Perlite is a natural product, derived from silicates of volcanic origin, subjected to high temperatures.
 
Properties:
Provides aeration| Retains water | Decreases substrate density | neutral pH | Sterile
 
Total pore volume: 95% volume
Aeration capacity: 65% volume
Granolometry: 3-6 mm 
Electrical conductivity: 3-5 𝜇S/cm
pH: 6-7
 
Because it retains water and nutrients, while providing aeration to the plant, expanded perlite is a product with special characteristics to be incorporated into the substrate. Improves drainage.
 
Applications:
Substrate component - Mix the perlite (5-10%) with the other substrate raw materials (peat, humus, peat coconut, etc.).
 
Attention:
Do not ingest. Keep away from food, drink and feed.
No special requirements are needed for its use.
