About Pallet Size We are now offering a new bulk ordering size for some of our most popular growing media: the pallet size. Due to certain shipping factors, we are able to offer an entire product pallet for the same shipping cost as smaller bulk orders. For this product, a single pallet consists of (60) 2 cubic foot bags. We believe this will be a great option for schools and commercial institutions.
