Potassium Nitrate - KNO3 Powder - Laboratory Grade - 1 Pound | 1 Lb

This product was great for my plants. Some plants I have don’t react to miracle grow, but they like this food. My fern likes it, they all so. It lasts a long time it does not require much for indoor plants anyway. I’m sure there are other uses, but I used for plants and works great

Worked perfectly in my application. May need to be milled finer for rocketry projects, but the price was right!

This stuff was almost impossible to find. I found a recipe in one of my mom's books regarding a "Pantry Plant Food". It works like a charm on indoor and outdoor plants. I didn't really need this much but it was so hard to find that I bought it when I found it. Pantry Plant Food recipe. 1tsp baking powder, 1 tsp epsom salts, 1 tsp saltpeter (potassium Nitrate), 1/2 tsp ammonia. Mix into one gallon of warm water.

Good product, in the garden

This is high quality kn03. I’m going to dilute it to supplement my vegetable garden. Gets excellent nitrogen & potash at the same time. Produced great tomatoes in the past using this with some calcium prills. Have 4 stars because $18.00 for 1 lb is way expensive. Need to find a larger size for the same amount. But other wise. Seems pure and ready to use for the garden. If you are going to make something else with it it will need a lot of milling. I think I paid too much.

Appreciate it exactly what I thought it was. Prefect for west I'm using it for

Good potassium nitrate, nice and clean. Does exactly what potassium nitrate is supposed to do. Dissolves well, burns… appropriately. No complaints. Five stars before anybody starts asking unnecessary questions.

it's exactly what it says it is.
