## Questions & Answers

**Q: Can this product be applied to grass lawn using a Broadcast spreader?**
A: I don't believe so! Used mostly in greenhouses. Add it to water.

**Q: Does this have to be mixed with water before applying or can you just sprinkle some around the base of the plant?**
A: I used it in a hydroponics setup so of course it was dissolved in water.  I don't see why you could  not sprinkle a very thin layer on the surface or mix into the soil. I am just not sure why you would want to use a water soluble fertilizer in that manner. The directions on mixing are based on ratios of fertilizer to water.  But give it a try. What can you lose.

**Q: Could I use this in my earthbox fertilizer strip?  Or would it be too potent?**
A: Just mix at half strength if your worried about being to strong

**Q: would this be good to use on a one acre food plot ?**
A: No, it appears the cost would be prohibitive - since you aplly this stuff every 7 to 14 days and 1 pound covers about 400 square feet - to cover one acre (approx. 43,500 feet) would then take about 100# every 7 to 14 days.
