Not sure what you mean by "original" but I use their "Ocean Forest" and will from now on! Close to harvest now after my first experience using it and must say this is the best I've ever done in the 20-some years of indoor growing! In the past I used Whitney Farms (NOT the Uncle Malcom's brand tho...it sucked) but it's hard to find where I'm at now so fortunately I stumbled across Fox Farms Ocean Forest! Sure it's expensive but what isn't with this hobby/therapy?
