foxfarms OF is good stuff. Like many said I would add perlite to it, they seem to have changed there recipe and it dosnt drain as well as it used to. Also I did have problems with some squirrels and raccoons while using it at first. But they seem to be over it, and dont bother me anymore.
2 bags per plant is alot tho, I think each bag can fill up 2, 5 gallon containers, so that would be 20 gallons of soil for each plant. I mean I guess if you think your plant is going to need that much then go for it, but I think its an overkill. 1 bag a plant should be fine.
