Siro Royal is a "GOLD" quality universal substrate ideal for planting and transplanting a wide range of demanding plants, especially flowering plants, with the exception of plants that require an acidic pH. It is enriched with controlled and slow release fertilizer that provides the appropriate nutrients for the healthy development of plants for 14 months. The natural humic and fulvic acids present in humus promote excellent conditions for the growth of the root system of plants, and in combination with perlite and coco peat, create a balanced aeration and drainage of the substrate.
