Years ago Lambert was the only peat sold in stores locally until other brands were introduced. The product had a large grind and an awesome amendment.

Peat is processed at different screen levels depending on the end use application.
Commercial trades uses a fine grind to fill those cell pack flowers and veggies that you get at the big box.
Big box store peat bales are medium to fine screened for general consumer use however I have gotten some that I consider peat dust off the same skid.

Local better garden centers as well as hydroponic stores will usually carry a course screened peat or a mix that contains it.

A manufacturer Promix has different grinds of peat that could work.
Amazon has a few choices which might work too

Shipping is pricey for a bale of peat ....
