Hydroponic Plant Nutrients - Mix your own

Here is a recipe to create your own hydroponic plant nutrients mix. I have not personally tried this recipe so I can make no guarantees as to whether it will work or not. Make it and use it at your own risk - or should I say at the risk of your plants... Use it at 1 t per gallon of water. In any event here it is:

Chemical	Dry Ounces	Grams	Comments
Potassium Nitrate	9	255	An ingredient in gunpowder; also called Saltpeter
Calcium Sulphate	7	198	Plaster of Paris
Magnesium Sulphate	6	170	Epsom Salts
Monocalcium Phosphate	4	113	---
Ammonium Sulfate	1.5	43	Principle source of Nitrogen in recipe
Iron Sulphate	-	---	Use a pinch only; maybe 1/2 t

Here's another one...

Chemical	Dry Ounces	Grams	Nutrient Added
Sodium Nitrate	12.5	355	Nitrogen
Potassium Sulphate	4	113	Potassium, Sulphur
Super Phosphate	5	142	Phosphate, Calcium
Magnesium Sulphate	3.5	100	Magnesium, Sulphur
Iron Sulphate	-	2	Iron

Mix all ingredients very well and store in an air-tight container. When needed use '1 t' for each gallon of water. In the table below the following apply: '1 teaspoon = 1 t', '1 tablespoon = 1 T' and I calculate '1 t' to be equal to 10 grams. Be careful with your measurements or you could very well create a mixture toxic to your plants. As for trace elements, these are usually accidental by-products of commercial fertilizers so here is another recipe solely for trace elements:

Chemical	Amount
Manganese Sulphate	1 t
Boric Acid powder	1 t
Zinc Sulphate	.5 t
Copper Sulphate	.5 t

Mix together well and store in another air-tight container. When needed add '.5 t' to 1 quart water and mix well. Add 1 liquid oz of this solution to 3 gallons of your plant nutrients solution from above.

Good luck ...
