PRO-MIX BX | 2.8cu ft - Loose Fill (57/PL)

General-Purpose Peat and Perlite Growing Medium, 2.8cu ft

General greenhouse propagation and transplanting work doesn't need a specialty formula, but it still needs a medium with dependable drainage and structure batch after batch. PRO-MIX BX combines fibrous, high-quality Canadian sphagnum peat moss with horticultural grade perlite, giving growers the drainage and aeration perlite provides without moving to a specialty high-porosity or coir-blended formula.

This 2.8cu ft loose fill bag ships 57 per pallet, sized for general greenhouse and transplanting use without the mycorrhizae or biofungicide additives carried in PRO-MIX BX's enhanced variants.

Premier Tech, a peat substrate supplier since 1923, launched the PRO-MIX brand in 1968. The BX line is the company's general-purpose peat-and-perlite formula, also offered with mycorrhizae or biofungicide blended in for growers who want those additives.

Frequently Asked Questions

What is PRO-MIX BX made of?

It's built on Canadian sphagnum peat moss with horticultural grade perlite added for drainage and aeration. Unlike PRO-MIX BX Mycorrhizae or BX Biofungicide + Mycorrhizae, this plain BX formula doesn't include those additives.

What is this formula designed for?

It's a general-purpose medium for general greenhouse use and transplanting applications, rather than a specialty formula tuned to one crop type. It suits growers who want a dependable, everyday peat-and-perlite base.

Should I choose plain BX or one of the Mycorrhizae variants?

Choose plain BX if you don't need the added mycorrhizal inoculant or biofungicide and want to manage those inputs separately or skip them. Choose BX Mycorrhizae or BX Biofungicide + Mycorrhizae if you want those additives already blended into the medium.

How is this formula packaged?

This is a 2.8cu ft loose fill bag shipping 57 bags per pallet. That's a standard commercial count for growers restocking a regular potting program.

Can this medium be used for seed starting as well as transplanting?

Yes, the peat-perlite particle size and structure support both germination work and general transplanting. Growers running dedicated plug and germination programs may prefer PRO-MIX FPX's finer texture instead.
