Serious horticulturists use this PRO-MIX growing medium when they need a stable, growth-promoting base for container applications. PRO-MIX BX uses biofungicide to ward off disease and mycorrhizae to retain moisture. Combined with a 75-85% sphagnum peat base and an introductory fertilizer, the result is PROMIX soil that is productive in many applications. Use it to start young foliage plants in trays, transplant vegetables to larger pots, grow perennial flowering plants in hanging baskets and much more. The starter fertilizer will be used up within 10 days, at which point you should begin a new program.

At Greenhouse Megastore, we sell PRO-MIX with Mycorrhizae in 2.8 cubic-foot loose-fill bags and 3.8 cubic-foot compressed bags. The compact bales expand to seven cubic feet of loose fill, giving you enough for 90 one-gallon plant pots. Both sizes can be ordered as a single bag or in pallets, letting commercial greenhouses and farmstand owners stock up. We guarantee the lowest price on all-around PROMIX soil.

PRO-MIX BX General-Purpose Growing Medium Features:

  • Contains Mycorrhizae: Mycorrhizal inoculum (Glomus intraradices) with PTB297 technology.
  • Peat-based growing medium with perlite and vermiculite.
  • Ideal for the production of vegetable transplants in large cell trays.
  • High water retention capacity.
  • pH adjusted for balance.
  • The 2.8 cubic-foot loose bag is 25-35 pounds while the 3.8 cubic-foot compact bag is 60-75 pounds (equivalent to seven cubic feet of loose growing medium).

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 or (57) 2.8 cubic foot bags of Pro-Mix. We believe this will be a great option for schools and commercial institutions.
Note: 10 or more bales of the 3.8 cu ft bags will have a longer lead time since it must ship via motor freight carrier.

Great option for sink organization!
Color: Black, Size: Large
This has been a great organizer! Everything stays neat and in reach. It drains into the sink so no mess on the back of the sink or countertop. We have bought this for my daughters work and her apartment as well.

Something I never knew I needed, and now can’t live without!
Color: Black, Size: Large, Color: Black, Size: Large
Absolutely perfect, high quality organizer. I was constantly reaching under the kitchen cupboards for sponges and drain stoppers which then cluttered up the sink while letting them dry before putting away. I love the size and option to put the basket on the outside edge for more space. It holds everything I need. I especially like the stone underneath so I can place it anywhere and not have to worry about a drain spout. Keeps my sink and counters clean and organized and looks great in my kitchen.

Best kitchen caddy!
Color: Black, Size: Large
This is the best kitchen caddy. It works well on the edge of my sink. It's a little bigger than I thought. My measurements were off, not there's. I propped up one side and it works beautifully. It holds all the sponges, soap, and cleaning utensils needed to clean your dishes. Now my kitchen sink is clutter-free. It also looks great!
