Pro-Mix BX Biofungicide + Mycorrhizae is a general-purpose growing medium that is great for a wide variety of plants as well as for transplanting applications. It provides the protection of a high-quality biofungicide while offering the growth enhancement properties of 100% contaminant-free mycorrhizae.

The 2.8 loose cu. ft. bag is 25-35 lbs., while the 3.8 compact cu. ft. bag is 60-75 lbs.

The 3.8 cu.ft. size is compressed and expands to approximately 7 cubic feet loose. That amount of loose Pro-Mix fills approximately seventy-five 8" hanging baskets, ninety 1 gallon pots, four hundred and fifty 4" round pots, or fifty standard bedding flats.

  • Contains Mycorrhizae: Mycorrhizal inoculum (Glomus intraradices).
  • Peat-based growing medium with perlite and vermiculite.
  • Ideal for production of vegetable transplants in large cell trays.
  • High water retention capacity.
  • pH adjusted.

About Pallet Size

We are now offering a new bulk ordering size for some of our most popular growing media: the pallet size. Due to certain shipping factors, we are able to offer an entire product pallet for the same shipping cost as smaller bulk orders. For this product, a single pallet consists of (30) 3.8 cubic foot bags of Pro-Mix. We believe this will be a great option for schools and commercial institutions.

The best I have found

Pro-Mix seems to have everything my vegetable and flower seedling need when I "pot them on" as the British say.
It also works for the edible geranium flowers I grow in my light tray. They produce best in 4" pots of Pro Mix watered with rain water.
Two bags it in a 65 gallon wheeled trash container to stay dry and be moved to where needed.
I'm not sure the delivery company loves it, but I do.

So far, so good!

Will know more after plants have grown.

Wonderful seed starting medium

I love pro mix for starting my seeds each spring. I’ve been using it for years with great success.

No fail seed starting

I love this product! Haven't lost any seedlings since I started using it. Convenience is a plus too. The extra I pay for this is negated by the labor I spend for the mixing.

Love to grow from seed

I have used BRK and HP in the past, try to stick with Promix even though it is peat based.

David Godfrey

Will be using this from now on

I have used Pro-Mix for 50 years for seed starting. Have never had a problem with the 3.8 cubic foot bales and hope to continue using it for another 50 years.

Perfect !!

Bought the big bail. This is the best stuff I have used for seed starting since it is so fine. I add a bit of pearlite And how can you beat free shipping on an item this size.

Great soil for seed germination

This soil can be used for flower and vegetable seed germination. I also use for transplanting and as potting soil for my hanging baskets and planters.

Generally happy

I bought the bag of mix and really like it. Light and fluffy with very few extra bits like clumps and sticks. I then bought the compressed bale and I've found more sticks in the top 4 inches of the bale than in the entire bag before. I am a little disappointed in the difference in quality. It's definitely still usable but with more effort.
