I only use Happy Frog and honestly, I dont see why that dude said its "low end" soil.. Its great.. Its only a dollar or so cheaper than Ocean Forest.. What exactly is the diff in the two? All I do is mix one 8qt bag of perlite to one 2.0cf bag of Happy Frog and ive never had any problems with it. Granted, im only on my secong grow and the first one I had to end early and throw out ( long story ), but the statement that "Happy Frog is low end soil" made me confused.. how can a $30.00 ( varies dep on where you live ) bag of soil be "low end" ? I think its better than Ocean Forest as I have heard that OF is bad for seedlings. And since I go straight from Peat Pellets ( 2-3 day old sprouts max ) into my final container with Happy Frog soil ( no transplanting here ), I feel it is a better choice for me.. Any info on this would be great thx
