Features
DX Seeding uses a superfine structure to ensure uniform germination. The 50/50 balance prevents waterlogging in the first 72 hours. The calibrated EC (0.6–1.0 mS/cm) protects cotyledons from root burn during the first critical days.
PG Mix starter fertiliser is integrated into the formula. It provides sufficient nutrition up to the first transplant. The incorporated wetting agent allows you to re-wet the seedling root zone evenly after the first drying cycle. Selected peat from the Baltic countries: consistently extracted from the same fields, season after season, ensuring batch-to-batch quality continuity. 30 years of selected supply chain and 7 million m³ of substrates produced since 1996.
