"I am having trouble finding a source for calcium
nitrate. Googling, I can find that it used to be commonly sold in a
15.5-0-0 formula.....snip" It is readily available in Canada in four
grades, each with an NPK ratio of 15.5-0-0. Supplier is Plant Products, who have
been in business
for some 50 to 60 years. I use their
Calcium nitrate together with their hydroponics fertilizer
7-11-27. Excellent when you are using RO or rain water lacking calcium.
