>Just curious... What brands of ferts are you guys using? I use Flourish Comprehensive Liquid and also Seachem Trace Minerals. They are $10 a bottle each. I have never done the math but I bet it about .30 a dose which I do once a week. Pretty cheap for nice plants to me. _______________________________________________ GSAS-Member mailing list GSAS-Member@thekrib.com http://lists.thekrib.com/mailman/listinfo/gsas-member
