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.

Comfortable fit, but the pattern looks a bit dated
Size: XX-Large, Color: Dark Green Stripe Knit
I grabbed this in an XXL looking for a comfortable, breezy shirt for the summer. The actual fit and feel of the shirt are really nice. It's a true relaxed fit that doesn't pull tight across the chest or stomach, and the knit material is surprisingly soft and breathable, kind of like a lightweight summer sweater. It definitely doesn't feel like stiff, cheap cotton. My main issue is just the design itself. I ordered the dark green stripe, and in person, the pattern just looks a bit dated, almost like a retro bowling shirt or old upholstery rather than a modern vacation button-down. I'm not the biggest fan of how the stripes look on me, so it has basically become a shirt I just wear lounging around the house instead of actually wearing it out anywhere nice.

Airy, 100 % cotton, crochet, button-down shirt
Size: XX-Large, Color: Dark Blue Stripe Knit, Size: XX-Large, Color: Dark Blue Stripe Knit
This feels super soft and airy. Even though it’s made of 100% cotton, it doesn’t feel heavy at all. I love the contrast between the dark blue and white. The fit is slightly boxy, and it doesn’t wrinkle whatsoever. It’s absolutely worth the price. I can’t get over how good-quality, versatile, lightweight, and soft this shirt is. I highly recommend it as a fun layering piece or a stand‑out top.

The Materials Are Very Soft And Durable
Size: Large, Color: Dark Blue Stripe Knit
It is ideal for warm weather or casual nights out because of its relaxed fit, which is comfortable without appearing overly baggy, and the soft, light knit material. The button-down style preserves the relaxed vacation vibe while giving it a polished, clean appearance. It looks great with both jeans and shorts. The fabric's ability to breathe throughout the day was one of my favorite things. The short sleeves make it perfect for everyday casual wear, cookouts, and vacations. It is comfortable enough to wear for hours without feeling heavy or stiff. For the price range, the buttons and stitching appear to be well-made as well. Without exerting too much effort, the shirt's fashionable appearance draws praise. The fit can run a little larger depending on your typical size choice, which is the only reason I am not giving it a perfect five stars. Sizing down can be beneficial if you prefer a more fitted appearance. Apart from that, it is a fantastic, adaptable shirt that blends ease of care, comfort, and style. A great complement to a casual summer outfit, without a doubt.
