## Questions & Answers

**Q: Will this product make stonger skin on foilage, or make plants resilient to. Spider mites and aphids?**
A: Silica helps plants build stronger cell walls and thus helps them be more resistant to pests, but it isn't a cure all type of solution. I would recommend that you look into how to raise the overall Brix level in your plants to offer the most resilience.

**Q: it can be used in hydroponics**
A: Yes, RAW products were all designed with hydroponics in mind. They are all completely water soluble

**Q: Can I use this to spray on my plant rather then soak it?**
A: i use it as a foliar. it is harsh on spray bottles and way less is more. a tiny  bit really works good luck

**Q: What is the best ph range for this product to be taken up by the roots?**
A: 6.5 - 6.8
