Premier PRO-MIX Organic Seed Starting Mix with MYCOACTIVE | 16qt - Loose Fill

OMRI Listed Organic Seed and Cutting Starting Mix, 16qt

Germinating seeds and rooting fresh cuttings both call for a finer, more moisture-even mix than a general potting soil provides, and organic growers need that mix to carry proper certification too. Premier PRO-MIX Organic Seed Starting Mix with MYCOACTIVE combines Canadian sphagnum peat moss, coir, and perlite with a soy-based natural fertilizer and Mycorrhizae from Premier Tech, and it's OMRI Listed for organic production.

This 16qt loose fill bag is sized for a full flat of seed trays or a batch of cuttings, giving growers enough mix for a complete propagation run.

About Premier PRO-MIX

The PRO-MIX brand traces back to 1968, when Premier Tech extended a peat-substrate business it had run since 1923 into packaged growing media. The MYCOACTIVE seed-starting line blends the company's own peat and coir supply with the mycorrhizal inoculant produced at its biotechnology lab.
