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.

PRO-MIX Seed Starter Organic Mix Features:

  • Formulated with quality all-natural horticultural ingredients for growing a wide range of plant species.
  • Contains MYCOACTIVE technology with Mycorrhizae, an exclusive biological growth enhancer that promotes plant growth, root strength and stress resistance for increased yields.
  • Provides easier plant care than standard mixes and results in improved seedling performance.
  • Organic fertilizer that gradually feeds plants for up to three months.
  • 16-quart loose fill bag
  • NPK: 30-5-10
  • OMRI-listed

amazing product
Model: 36 Sqft
actually surprised how great the product is and way better priced then other companies. its sticky and also has thickness enough to cover metal parts on cars. i would recommend 100% just ordered another 18ft for the rear deck and to have some extra! does not smell. easy to install and helps stop vibration.

No more scrolling. Best price, abundant, does its job.

I have it under the closed cell foam. It’s great. Just as great as Killmat and all the other butyl rubber products. Let me ask you to do something: look at the people who rated it 1 and 2 stars. No reviews. No pictures. Why? They don’t want to see the most budget friendly product getting sold. That’s some weak business. Rest assured you’ll be happy with this. Why did I buy both types? Butyl rubber helps the car not be a tin can. It keeps the outside road vibrations out. Closed cell phone keeps your music in. They work best together., Kumbaya, we have unity! We can get along, even in this age in time. The closed cell foam is cheap. You’ll get it to replace the nasty cloth under your carpet. Do the knock test. It won’t help. You need this too. And truth be told, I prefer that it has no name on it. I’m not paying money so you can brand yourself on my car. Ps: these products go on and don’t come off. Don’t mess up. It’s the same for the competitors and the closed cell foam. One shot. Do it right the first time. I’m writing this review after I used up my first box and am getting more. Happy returning customer.

Great stuff, well made.
Model: 36 Sqft
I was very pleased with this product. Very easy to use, flexible enough to conform to the variations of the surface (floor of the car and some side panels), and it stuck well. I topped it with a similar foam product to provide additional sound deadening. The car has not been run yet but the panels are much "quieter" when tapped on vs before with undercoating, felt and carpet. Seems well made and I expect no issues in the future.

Good inexpensive sound deadening
Model: 36 Sqft
This stuff works great, it's easy to apply, sticky, easy to cut. 36 ft.² was enough to do the inside and outside of my doors the roof, the wheel wells and rear fenders. Plus, it's a lot cheaper than others.
