ive tried promix and have had poor results, it is peat based and the ph tends to fluctuate with time but thanks for your input i guess i should have listed the soils ive tried so here they are: Shultz, Dutch Treat (the worst EXTREMELY HIGH IN NITROGEN), Promix BX, regular Promix, regular C.I.L potting soil, C.I.L seed starting mix (works but not satisfied with such a peaty soil that messes with ph)
