source for KNO3 and K2SO4
Three weeks ago I placed an order with PCI Scientific supply for KNO3 and
K2SO4. This was one of the sources listed in a posting Jan. 6. Three weeks
passed without receiving my shipment, so I called to follow up. After a few
calls I was finally told that they would no longer be shipping chemicals to
individuals because of the explosive nature of the chemicals. Seems PMDD
ingredients are getting tougher to find. Maybe I'll see what I can find at the
local garden centers.
