Magicide Posted December 3, 2005 Report Share Posted December 3, 2005 Since I've been given the advice here and read it on other forums I wanted to start doing macro dosing of Potasium Nitrate (KNO3) and Potassium Phosphate (K2PO4) but I can't seem to find any. I went to Hole's Greenhouse in St. Albert and they only carry fertilizer with other additives included. The fish store showed me another option that had a blend of Potassium, Phosphor and Nitrogen but I wasn't sure if that would work out so I said no. But I still don't know where to get those chemicals. Ideally I would like St. Albert since the roads are bad right now but north Edmonton would work too. Anyone know a source?

Big Red 265. Posted December 3, 2005 Report Share Posted December 3, 2005 You can order KNO3 from London Drugs. A few years ago I got a 2kg bag from them. Quote Link to comment Share on other sites More sharing options...
Aquanerd Posted December 3, 2005 Report Share Posted December 3, 2005 Look at hardware stores for Tree Stump removers. I hear Green stump remover is all KNO3. Or I ordered all mine from Homegrown Hydroponics it was cheap and fast. Quote Link to comment Share on other sites More sharing options...
cgmac Posted December 9, 2005 Report Share Posted December 9, 2005 I found K2S04 Potassium Sulfate in the form of No-Salt at Safeway about $6 I found KH2P04 Phosphate (Fleet Enema)at Walmart...I bought generic for $1.87 I had trouble finding a source for nitrate so I broke down and bought the Seachem stuff.
