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.

Works awesome. If you don’t use them within a year replace them. It’s way cheaper than a tow truck!

Bad Product

There was no pressure in the can. It would not even inflate a bicycle tire. Be careful there is no amazon refund or return with this item!

IT WORKS, IT REALLY WORKS!
Size: 16oz, Size: 16oz
I carry a tire plug kit in my van. Low pressure light came on and quickly made my way to air pump. Checked out tire and was at least a 5/16" bolt right between tread, very easy to locate (hissing). Inflated tire, prepared plug, pulled out bolt, inserted plug done. Almost home light came on again. Used water soap and plug was still leaking. Tried double plug and still leaking, but would take days to trigger low pressure light. Tire still had decent tread and didn't have facilities to patch, so got a can of fix a flat. I have never believed in this stuff, but it worked. No low pressure warnings for about a month. Around here they would charge $50 for a patch, 2 .25 cent soft rubber plugs and fix a flat, problem resolved!
