I thought Cha-Ching was the one that is "supposed" increase the flower "hardness". If you ask me those three solubles FoxFarm markets are worse than the Tiger Bloom crap. I just threw away samples of that crap I was given 3 years ago when it was first introduced. Grow organic.just my opinion but i think beastie bloomz does a hell of a job. didnt use it for quite awhile cuz of the price but i can tell a noticeable difference in the hardness of my budz. just my $0.02
