Daltons Organic Seed Mix

Daltons Organic Seed Mix is manufactured using the finest quality BioGro certified products, including naturally composted bark, organic materials, NuFert and pumice; blended and screened to produce a high quality medium suitable for all seed germination and cell growing. It includes NuFert, a BioGro certified slow release fertiliser produced by infusing nutrients into Zeolite granules. Plant roots then extract these nutrients, resulting in a more efficient uptake and stronger long term growth. Also includes Bioinoculant Granules, chemical-free friendly fungus for natural disease suppression and healthier plants.

  • BIOINOCULANT GRANULES for seedling health
