Thanks for the info. I would assume to be competitive they would all have similar procedures. Maybe it’s what they do to it once it’s inside that makes it “special”They all store materials outside. The space required makes it prohibitive to store everything indoors. I took a peek at Aurora Inovations which makes Roots Organic. They have covered facilities where they likely mix the product but the materials are stored outside. The FoxFarms image I posted doesn't look like a mixing facility but a storage facility. There are several large warehouses in the area with likely one being where they truck the materials to for mixing. I just want to point out that I see nothing wrong with storing the materials outside. It's pretty much the only feasible way to store them.
