Review: Excellent fertilizer for the seedlings - I use this fertilizer when I plant my seedlings. A very good fertilizer, none of my seedlings died and all them are doing very well. Very happy with the quality of the fertilizer.
Review: When replanting this is an absolute must! - If you're having to repot plants or even plant plants in your yard or garden This is an absolute must and a game changer. First of all when you go to replant something you need to trim away at the roots to a certain degree I always do half and I always have, then you tease the roots meaning breaking them apart I will even bang the roots on a solid object to loosen up all the old dirt. This biotone is a great value for the money. By using biotone you're increasing the roots strength and thickness while also improving your plant growth your plant health and I must say it is such an easy product to use All you do is sprinkle the adequate amount for the amount of roots that you're planting and you will have the best thriving plants thriving in great organic matter I have gone through about 12 bags of these over the past 3 years That's how fantastic biotone is I learned about this product when I worked at a premier garden center.

## Questions & Answers

**Q: what are the N-P-K values**
A: 4-3-3

**Q: Can I use this in potted plants?**
A: That's all I use it on.   I've used it for years and it's been great.    I use it when I get plants from wherever ( nursery, Lowes, Home Depot, etc.) and want to put them into pots.   I use the Bio-Tone starter to be sure they get good root growth and to make sure the transfer from little nursery containers to a bigger pot are successful.

**Q: I used this for the first time last night.   It smelled like organic fertilizer.   Today, I went to use it and it smells like ammonia.   Is this OK?**
A: Organic fertilizers can sometimes continue to compost if kept in a very warm place.  The nitrogen heats it up further causing the ammonia smell.  If the bag doesn't feel too warm, this is not a big deal, but I recommend you store it in a cool place to maintain the natural N-P-K balance and micro-organism makeup.

**Q: Can this be used in a potting mix (vermiculite and coconut choir) for starting seeds? Or will it cause burn?**
A: Yes, definitely use it for potting mix- it promotes root growth like nothing I've ever used before and the strong odor comes from the mycorrhizae fungus- not from anything that would burn the seeds.
