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.

My Honest Positive/Negative View From My 3 Cats. Different Sizes & Ages. Indoor Cats.
Color: Dark gray, Size: 23"L x 15"W x 1.5"Th
POSITIVE: My cat likes the mat; it's very soft & keeps her content & warm. NEGATIVE: It slides very easily even though there's a grip fabric on the bottom, it's only sewn around the edge so it doesn't stop it from sliding. My senior cat did slip off it & fell. She won't go near it. She was limping for a little bit. I hand sewn a few spots in the bed to connect the top & bottom more securely. Cats didn't like or try to use it until I put a couple toys and some catnip then one of my cats was willing to lay on it. I also wish there was padding on it. I put in on her blanket so it could be more comfortable to sleep & feel secure. I don't know why they don't like the smell of it, but I hope with time, my cat will have her scent on it enough where it becomes her favorite bed.

Our puppy loves this mat
Color: Latte coffee, Size: 35"L x 27"W x 1.5"Th, Color: Latte coffee, Size: 35"L x 27"W x 1.5"Th
Our new puppy loves this bed for his crate. It is thicker than many of the other crate mats we have looked at and extremely soft. I also appreciate the little silicone pattern on the bottom that keeps it from moving around since we take it in the car. I can’t speak to the self warming piece though. We have a self warming bed for our cat and it has reflective fabric on it similar to what you find in a Columbia omniheat coat. This has nothing like that. Either way it is our puppies favorite mat and so far one of the few he hasn’t chewed to bits. That alone makes it 5 stars for me.
