Cool -- Mark and SG -- Please Keep us posted on your findings! Im really curious as to see how your results will turn out. I think I'll pot my other mex pings up in the new batch I made last night.
NAN - thanks for the info!! Pings are awesome lil' plants man!!
BTW, how alkaline is vermiculite anyway? Just curious if it has that much of an affect on the alkalinity of the mix. I was also wondering if pumice is more or less intert and if it had any adverse affect on the alkalinity as well. Sorry for all the questions, I think the world of pings will be my next new "thing" :-)
