kno3

I have some kno3 and wanted to use it as a fertilizer, I was wanting to know how much to a gallon of water so I won't burn my plants?

get your self some Sulfur and Charcoal and you have Blackpowder. where did u get this potassium nitrate?

Since you're using it for potassium, why don't you get a teeny carton of molasses instead. No risk of burning plants with those

I do make black powder with out sulfur and I make charcoal out of naptkins.

But I only wanted to use it for fertilizer because I have it alredy.

I got it from ebay for about $4 a pound.
