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.

Puppy loves it!
Size: X-Large, Color: Teething Bone, Size: X-Large, Color: Teething Bone
My small puppy loves this bone! I originally purchased this for a larger dog, but my small 10 pound puppy loves it more. It’s good quality and a softer material for puppies!

A hit, but could be stronger
Size: Medium, Color: Ring Bone, Size: Medium, Color: Ring Bone
Gave this to my 11 week old pittie, and she did significant damage within 15 mins. She left a pile of chewed bits on the couch but thankfully didn't eat them. Definitely don't leave unsupervised. That said, she LOVED it and it seemed to help her teething gums so, I'm still giving it a 4/5 Puppy pics for tax

FOR SHORT TIME USE
Size: X-Small, Color: Ring Bone
My puppies love this. After a couple of weeks, it is worn so I throw it out and buy another since it's reasonably priced. I don't want them to actually ingest a chunk of this.

Great for our puppy
Size: X-Small, Color: Ring Bone
This chew toy has quickly become our puppy’s absolute favorite. She’s just starting to teethe, and keeping her busy and comfortable has definitely been a challenge, but this ring has been a lifesaver. She was interested in it right away and keeps coming back to it on her own, which is a huge win. The chicken flavor seems to really hold her attention, and it gives her something appropriate to chew instead of everything else. It’s the perfect size for a very young puppy and easy for her to hold and gnaw on without getting frustrated. It keeps her occupied, helps soothe her gums, and gives us a much-needed break during those teething moments. If you have a puppy just starting the teething phase and need something safe, durable, and engaging, this is an excellent choice and one I’d happily buy again.

Nylabone Ring Bone
Size: X-Small, Color: Ring Bone
My dog loves these. She chews them into pieces which helps keep her teeth clean. It is a mess to clean up. She chews and spits out the pieces. She is 6 years old so not a puppy.
