I love how it's the grow stores.....Most don't even have the space to store pallets and pallets of soil for a long time. I cycle through 4 fresh pallets a month of most soil offerings. I could throw stores under the bus,as I have had people come to my shop after getting a gnat compromised soil. However I will defend all hydro shops.
Maybe......It is your precious manufacturers who are mass producing soils and storing them for 6+ months before they make it to the wholesaler, and then who knows how long before it reaches the retailer. Most soils have a date on them....For example the Pro-Mix order I just got in was bagged 8 months ago....Wonder where its been stored for the last 8 months.
