Thanks Stush! So you lower the pH for your Sansevierias, stapelias & huernias...what else would you use that with? I got some of the sulfur stuff you mentioned. I was thinking it would be good in my "tropical" plant garden...with alocasias, philodendrons, strobilanthes, ferns, chenille ground cover, dracaena, taccas, diffenbachia, etc etc...
