Dear Lucky,

 

You would not want to use a powder rooting hormone sine these products contain large percentage of talc (usually 99.9-99.2% talc). Talc being completely insoluble in water will become a barrier to the union.

 

When you trialed, what methodology did you use and the ppm of the auxin?

Did you use a liquid application?

How did you dissolve the auxin?

How did you apply?

What was the ppm of the auxin?

What was the percentage of takes and what was the total number of iterations?

Did you use a control lot? 

What was the season of the treatment? 

regards

MRK
