## Questions & Answers

**Q: What is the NPK analysis for this product?**
A: It has No NPK rating. It seems to be purely an irganic seed starting medium with no added fertilizers.

**Q: Does this product contain perlite?**
A: Thanks for the question, yes! This mix is made up of sphagnum peat moss, perlite, vermiculite and Purple Cow Organics compost.

**Q: 12 quarts weighs 25 lbs. Why does the description say 6 lbs?**
A: Thank you for your question! The measurement you're referencing is for 12 quarts of water. Our Seed Starter Mix is less dense than water, so it weighs less.

**Q: how many cells in a starter tray will this bag fill?**
A: Thanks for the question, the answer to that depends on what type/size tray you are using. There are 12 quarts in this bag, so I'd recommend finding the volume of the tray you'd like to use in quarts and dividing that number by 12 to find out how many bags you'll need.
