## Questions & Answers

**Q: Description says "snip'n dip 8 .75 ounce packets", but the picture shows "hormex rooting powder #3" what is it the #8 or #3 powder & in a bottle?**
A: There are different numbers to the powders based on how hard it is to root plants. You have to select the powder that best suits the need of the plant you're trying to root. If you look in the pictures there is a chart listing what number you need for different plants. Once you've established which number you need you have to select from the different options when powder you want.

**Q: I’m a novice. Is this “ organic”? Or used by organic farmers/ growers?vs associated with potential  environmental or human health problems? Thank you.**
A: I use these products and I am an organic gardener. When I looked into this was a lot better then some of the other cloning/rooting products. Such as the ones for cloning cannabis. Depending on the type of plant you are cloning you may not even need to use anything.

**Q: If i buy #16 for very hard to root plants, will it also work on easy to root plants? iow can you use the high strength, 8, 16 and have success no matt**
A: The brochures that came with the product (#16) says you can go to  hormex.com/plantist 
As for me. I have tried five times to get roots to start of on some woody stemmed plants (cannabis) & the 1st 4 failed. I took 4 cuttings from 4 different plants & put #16 on 2, #3 on1 & none on 1 Always uncovered in & or near a South window 1st Fail; Used moisture control potting mix(2wks), 2nd F. =perlite,(2wks) 3rd F. i sterilzed potting mix(3wks), 4th F. City tap water in individual jars & rotated a bubbler.(3-4wks). Succeeded when i moved away from window & used a 10"deep plastic tub filled  1/3 with tap water, an air bubbler & 2 CFL light bulbs in cheap heatlamp fixtures. After 1wk. all had 1/2-2" roots. After 2wks. all had  1 1/2-4" roots.. With or without rooting hormone, although the ones with the #16 do seem to be doing better on  these woody plants. I've been propagating VIA stem cuttings for 50yrs. & have always had very good luck with any opaque container, just keep it covered in a bright area. BUT NO DIRECT SUN!! Also usually best NOT to use soil (unless sterilzed ), Perlite or sand seem to work best for me, Even if its   dirty sand.

**Q: Can i use (hormex rooting powder number 8 difficult to propagate plants) for shoot (date palm) and lemon or there is any other hormone is the best ?**
A: I am not familiar with those woods. If they are fibrous and hard, woody....then it might be the right one. It is the highest concentration that I currently use.If they are softer, green shoots, like vegetable stalks, then you may need one that is less concentrated. The active ingredient is indole 3 butyric acid. I have concentrations from .1% to .8%. Hormex #16, #30 and #45 are all progressively stronger. #45 is the strongest. Hardwoods will need the stronger ones, semi-woody will use the #8 or #16, while soft stems will use the less concentrated like #1 or #3. I use #8 because it is good for most plants that I work with. Hormex is the best product I have used, it is very successful. Good luck, I hope it works for your cuttings !   :-)

### ⭐⭐⭐⭐⭐ Review
*by P***8 on 24 February 2025*

Used this Hormex #8 to root a heap of dragon fruit cuttings and had significant root growth on 27 out of 30 cutting in 2 weeks. Without rooting hormone I’d be lucky to get this amount of growth in 8 weeks. Got recommended Hormex #8 by a large scale dragonfruit grower and I’ll say he wasn’t wrong. Thought I’d give this a try on some Hoya cuttings that also generally take a while to root and I had roots pushing through in 3-5 days which was way above and beyond my wildest expectations. East to use, extremely happy with the results. Big fan of this #8. Rarely give 5 star reviews but I truly believe this product deserves the highest rating possible. Blew away my expectations by a lot based on my decades of experience with other rooting hormone products. My grading scale My ratings are based on one or more of the following characteristics. Please note I consider 4 stars a very high rating. * 1 Star - unsatisfactory - poor quality - misleading or false ad copy - would not recommend to anyone * 2 Stars - below expectations, needs improvement - inferior materials And/Or design - poor value * 3 Stars - meets reasonable expectations of quality, design and durability at the price point * 4 Stars - Exceeded expectation - above average performance of materials, design and craftsmanship - good value - would recommend * Five stars - Truly outstanding - exceptional quality and design - exceeded all expectations of materials, design, craftsmanship, durability and value. Would recommend without any reservations 5 point rating scale: * 1 - Unsatisfactory * 2 - Needs improvement * 3 - Meets expectations * 4 - Exceeds expectations * 5 - Truly outstanding
