Happy Frog is good stuff; you just have to make sure you don't have a big clump of bark sitting on top like that. Although I've never seen Happy Frog with that much bark! Maybe a 'bad bag'?the bark came in part of the fox farm happy frog soil mix that i am using.. I tried to move as much as i could away. would roots soil or ocean floor be a better option for next time? my hydro shop doesn't have too many options.
