i get blocks of compressed coco coir ($7.99) and a bag of cocoa shell mulch($9.99), add water and mix it all up in a 5 gal bucket and i get what i concider to be the best yet i have used. i get 4 blocks per package and each block breaks up to 2 cubic feet, wich is a lot. i have tried a few different mediums and this is so far my fav for outdoor and hydro
