Why is this PRO-MIX Organic Gardening Blend so cheap compared to other PRO-MIX varities?

I need to transplant two from solo cups but I'm on a tight budget. I have these in my local Walmart for $12 for 2cuft. It's OMRI certified, it has mycorrhizae etc. What's the catch with this blend? Can I just use this and amend it with EWC, Bio-Live and fish hydrolysate and be good to go or is there something I'm missing in this equation?

I used it once. Did not perform as well as promix. The main difference is the addition of coco. Anyway, it has an overall finer texture than hp, held too much water while at the same time being difficult to water evenly due to compaction.

Looking at the price tag it's even cheaper than buying peat moss itself and ingredients don't look bad.

  • Sphagnum peat moss (60-70% by volume)
  • Perlite
  • Coir
  • Gypsum
  • Ground Limestone (for pH adjustment)
  • Wetting agent
  • Mycorrhizae
From your comment I infer that you didn't have a big issue either. I think I'm inclined to try it, it's better than getting these two root bound in solo cups.

I bought 8 bags the beginning of summer used about a half a bag and I wasn’t impressed with the few plants I used it with. The other 7 unopened bags got returned to Home Depot. Currently using sunshine mix 4, but no luck finding more. If I can’t find the sunshine mix, then I will be trying the Promix hp.

I used it outdoor this year, though amended it with EWC, GG 4-4-4, more perlite, Dyno etc. worked pretty well. Fair warning it’s slightly hydrophobic so you’ll want to introduce water when building/amending for your pots to save a headache later.

I've been using it purchased at my local walmart on my last few early veg before putting in the ground. I use synthetic nutes. Plants seem happy with it. Here's a plant that grew in it that I chopped a couple weeks ago.

It's 1cu. ft. compressed for $12, my local gardening store just bumped the price of 3.8 cu. ft. PRO-MIX to $62. So even if I buy 4 of them, to match the quantity that's still $48. I should have bought some PRO-MIX HP when they were still $50 so I wouldn't have to venture out to this one. Another factor is that I don't need 3.8 cu. ft. right now and would prefer to spend that money on worm castings instead.

Thanks for everyone for their inputs, I appreciate it!

I sent Pro-Mix an email asking what was the difference between the red bale you can get at Walmart and the HP.
They replied that the HP has more perlite for better drainage, that's it.
I did not ask about the organic pro mix in the yellow bale. My personal experience was my plants liked the red bale better, they did not like the organic and I ended up transplanting them to better dirt.

Thank you, is this the red one you tried? Interesting that the ingredients look pretty much the same, I wonder why one is organic and the other one isn't.

The website says "1 cu. ft. compressed pack bag contains 2 cu. ft. of potting soil"

Do you know if PRO-MIX HP (or similar bales) are compressed as well? Should I consider 3.8 cu. ft. HP as 7.6 cu. ft.?

The cuft number they put on compressed bags and uncompressed bags tells the final volume they fill after broken up.

2 cuft of any soil/coco/perlite or anything of the like, whether compressed or not, will fill 2 cuft of space when broken up.

The red bale is peat, coco, perlite and dolomitic lime. My guess was the ph was different on the organic.
