Bcuzz bloom is awesome stuff and another dope line is Green Fuse.Bcuzz bloom stimulator - same stuff as in their bloombastic without the clay or PK sources.... essentially molasses & kelp (sugar and amino acids, micro nutes n other goodies) as the main constituents from the research I have done. It doesn't make any gunk appear in the rez and is used from week 2 bloom to flush @ 0.5 - 1.5ml per L
