I would not advise a 10% dipping solution of bleach unless you mean
household bleach cut with 9 to 10 parts water for every 1 part bleach.
About 13 ounces of household bleach for a gallon of dipping solution.
Household bleach is a 5% hypochlorite solution. All of the recommendations I
have been given are for a 0.5% hypochlorite dipping solution. The Wal-Mart
type liquid swimming pool chlorine is usually a 10% hypochlorite solution.
If you have that, it is generally less expensive and only 6.5 ounces are
needed for a gallon of dipping solution. I leave my TB and PCI rhizomes in
the solution for 20 minutes or so and then rinse thoroughly in running
water.
Instead of the artificial potting mix, why not use an amended garden soil?
If the plants are not going to be in pots for an extended time, then you can
transplant the entire potted plant with the soil and minimize the
disturbance of the root system. I grow over 2200 potted iris every year. I
use a 50% good top soil/50% forest compost mix with great success. The pots
need a better water retention mix than normal garden soil because of the
root masses exposure to more heat and subsequent water loss. Of course most
of my potted irises are TBs so the situation is not identical. However I
have also successfully grown PCIs in the same mixture. Again not identical
but an indication that it could be successful.
