## Questions & Answers

**Q: what is the recommended dilution rate per gallon for this product?**
A: First, dissolve 2 pounds dry calcium nitrate in 1 gallon of water to make a liquid concentrate.  Then use 1/2 oz of the liquid concentrate per gallon of water on your plants.

**Q: This says it's 15.5% nitrogen and 19% calcium--what's the other 65.5%?**
A: It is mostly water. Calcium Nitrate formula is Ca(NO3)2.4H2O and that shows 4 molecules of water.

**Q: Will it help mangoes trees?**
A: Hello,

This product will work well for your trees if they are deficient in Nitrogen and Calcium.

**Q: Can it be added to the water reservoir of a grow box?**
A: Yes but it is like a teaspoon per quart. 
It stops your tomato plants from getting blight.  I use every year with great results. You can actually spray it on the fruit as they begin to grow. No need to spray the plant. Just spray the fruit.
