Looking at all of the high CBD strains out there is seems like you plant a number of them and have a small chance of getting one which will have a high CBD low THC content but most will be 1:1 ratio and some high thc low CBD. I would like to grow a batch of cannatonic with high CBD low THC for medical purposes. My question is if I buy a few seeds and only 1 in 24 will yield the results I want can I feminize seeds with colloidal silver on one plant and use the resulting seeds to plant over and over until I get the desired mother plant or will this result in the same plant genetics every time? Having trouble understanding phenotypes of strains.
