I myself never used any FF products before,,, cept the big 3 powerhouses in phous,, open sesame, beasty blooms and cha ching.. Costy stuff,, to me worth every penny.. I use the GH products,, and they have a dry kool bloom which will really work with most fertilizers,, cept it's atad cheaper than FF.. But I do love that tripack of what I call 'juice'. I have seen alot use FF and get great results.. GL and Knockem dead and Keepem Green
