I had bears attack my bags of FF soil supplement. Not sure what they were going for there. They never touched any of my plants once I added the soil to the ground. I use FFOF because it has more nutrients that Happy Frog. FFHF is mainly for starting plants where FFOF may be too hot for starting new plants but has more nutrients that the plants need for the long term. If you use FFHF you probably need to add a few more nutes later in the growth cycle.
