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 value!!
Color: White, Size: 6-Tier(10.7 x 14.5 x 65.3 Inches), Color: White, Size: 6-Tier(10.7 x 14.5 x 65.3 Inches)
Totally worth buying! The assembly is tinkertoy easy and they look nice! I bought four of the six tiers for my small home art studio.. one for books and three for all else. I didn't want big heavy shelves and these are light and stable! I put them with a couple other storage pieces I already had, painted a piece of 1x12 lumber white, to put across the top of them to make one long shelf and installed a couple of battery operated puck lights in them, and voila; a large, stable unit without the intimidating weight or price. If my little art studio were bigger I would buy more of them!

Looks great, gets the job done, definitely not high-end
Color: White, Size: 6-Tier(10.7 x 14.5 x 65.3 Inches)
I purchased not one, but *two* of these shelves for the purposes of storing my massive hoard of plush toys. For what I purchased them for, they get the job done swimmingly and they look great with the rest of my room. Assembly was simple, and although it was fairly easy to figure out, the provided instruction manual may not be easy for some to make sense of. There are also provided pieces for mounting the shelves to the wall for added sturdiness, and though they are included in the parts list, there are no provided instructions for them. One thing buyers should be aware of is the shelves and legs may arrive dirty with the dust and dirt from the factory. It's relatively easy to wipe them off with your hand, but it may not be a good first impression. As other buyers mentioned, a few of the pieces came with visual imperfections that, while easy to hide, may turn away those who are more particular about aesthetics. For the price however, the shelves are still well-made. Other buyers have mentioned concerns about the sturdiness and stability of the shelves. I cannot comment on the sturdiness as plush toys are not particularly heavy, however the shelves do exhibit a wobble (which is to be expected for this particular make of shelf; one without structural support in between the beams). That being said, though it wobbles, it doesn't feel as if it will fall apart easily. The pieces are all solid wood, as well. One negative is when I was putting on one of the feet for the second shelf, I'd twisted it tight (as I did with no issue for the other pieces), but for this particular piece it caused the glued in screw component to pop out. I had to use pliers to remove it from the shelf so I could use one of the spare legs instead. I did not face this issue with any other pieces, but it should be kept in mind that the application of glue across the pieces does not appear to be consistent. All in all, it is a good shelf and I am satisfied with my purchase. I did not expect a pristine or elegant shelf (nor did I intend to buy one), as this is a very fairly priced shelf. I got what I paid for.
