Siro Royal

SIRO® ROYAL is a universal "GOLD" quality substrate ideal for the planting and transplanting of a vast range of demanding plants, especially flowering plants, with the exception of those that require an acidic pH. It's enriched with a slow controlled releasing fertilizer that provides the appropriate nutrients for a healthy plant development during 14 months. The humic and fulvic acids present in the humus together with the perlite and coconut peat provide effective aeration and drainage to the substrate promoting growth conditions to the plants' root system.
