i'll second Coho's thoughts, perlite and dolomite make it much nicer
i've had good luck with it, though fungus gnats are a common hitch hiker but they can be dealt with pretty easy
Dont mind the attacks your gonna get from everybody on here. I think weve all used Miracle gro Once and have had our issues. Now I dont know how many grows you have below you but I think with some experience we can make MG work.. Im working on using it now cut with Black Kow now. I didnt use any amendments but but I probably should. We'll see how the seedlings react.
