## Questions & Answers

**Q: Lotus has a unique look and feel. Why is that?**
A: Due to the complexity of our powdered blend, Lotus Nutrients will have a consistency similar to kinetic sand, which is exactly as it should be. Its unique texture is caused by the multitude of essential micro and macro nutrients we use in our mix.

**Q: Can I expect Lotus Nutrients to completely dissolve?**
A: Although you may see some residual undissolved humate casings left over in the solution, all nutrient content has been released. The end solution and these leftover residuals will have zero negative impact on your grow.

**Q: Do I need to use any other products with Lotus?**
A: Lotus was designed as an all-in-one product line, without the need for additional nutrients outside of the recommended feeding schedule. Our Pro Series formulas are designed to give your plants everything they need to produce unmatched harvests.

**Q: Is Lotus organic?**
A: Lotus is a naturally derived product composed of raw ingredients containing essential micro and macro elements for all your growing needs. As a grower, you can expect beautiful, clean end results, but is not a certified organic product.

**Q: When applying to soil, should I mix Lotus with water first?**
A: Yes. In order for the macro and micro elements to be fully activated and utilized by the plants, Lotus should be mixed with water when applying to soil. We recommend following the feeding schedule on our website for optimal results.
