Here is the basic question, I can no find a cheap source of Potassium Nitrate within my local area. I have read on the internet about lengthy refinement methods and i have purchased the product of Ebay (for an expensive $15 a pound), however I am certain that it must be able to be attained cheaper. I have rang 5 nurseries and out of the three who knew what it was, only one stocked it. However the one who stocked it refused to sell it to me, openly expressing his assumptions that I will be using it to make explosives. anyway, the basic question is, "Where can i get KNO3 in Sydney". I hope that i dont sound like a complete idiot as this is my first post and i hope to bcome more self reliant in the future.
Thankyou all.
