This bulk seed starting mix is an all-purpose potting soil for professional and hobby growers everywhere. Use peat-basted seed starter soil to kick-start produce, herbs, flowers, cuttings…you name it! It's particularly effective for starting perennial flowers and shrubs indoors before transplanting them outside.
PRO-MIX Organic Seed Starting Mix has a 6-1-2 NPK ratio, which is ideal for green, leafy growth and also makes a good fertilizer. MYCOACTIVE technology produces stronger roots to help plants resist transplant shock and general stress - and spur them to grow up to 20% larger than standard seed starting soil. The coco fiber maintains good moisture levels to prevent rotting.
A single application of PRO-MIX seedling starting soil will feed your plants for up to three months, offering the sustained nutrients they need at this early stage. It's OMRI-listed for organic gardens and requires no additional mixing or preparation. Greenhouse Megastore sells PRO-MIX seed starting mix in bulk for high-volume growers and has free shipping on qualifying orders.
