Dear John,

You can make a dilution of the bean itself, crush the bean in water and
make a mother tincture at 10%
From it make  let say 6 or 8 Centesimal dilutions (every 2 CH, or else),
from 1C to 30 C

Have few dozains of beans in petri dishes and cotton
water them says 2ml every 2 days with the water used for the mother
tincture and the same used for the dilutions, and with the dilutions
prepared. Make sure beans are almost the same weight.
prepare 6 beans for each dilution to get an average.

Shaking? hammer around 10 times the bottle hal full like suggested by
Hahnemann on a telephon book. After 5 to 8 days you can see the
differences, please mark the petri dishes, or if you dont have any use
bottom plastic glass.

First after selection of the bean, growth few of them to evaluate the
amount of water required and function of the bean size and the temperature
of the room.

Have a nice experiment, All petri dishes must get the same amount of liquid
at the same time.

RRC
