Q: Companies that have rooting hormone, colchicine, gibberellic acid, etc.

We don't have quite what you have asked for, but we do carry a liquid kelp 
concentrate (Northern Pacific kelp processed at low temperatures) that 
contains many natural growth hormones and enzymes.  In our growing tests, 
we have found that cuttings soaked in a diluted solution of this product 
root very quickly, and foliar sprayings stimulate healthy growth of young 
plants.  A quart is $4.95 plus shipping (makes 32 gallons of solution).
