@Sativied I am on the same page as you regarding the tissue culture. Eventually tissue culture will replace "mother plants", because the tissue culture can be kept completely sterile and free of anything that may mutate its genetics or sicken it. So far only a team in China has been able to successfully tissue culture cannabis (from cell to full grown plant). Skunk Pharma in PNW (
http://skunkpharmresearch.com/tissue-culture/ ) is getting
close to success, and on some other forums there are threads of people getting close. At the Humboldt Cup DJ Short was saying that hopefully old valuable mother plants that have sickness can be "restored" back to their original health by going though the tissue culture process.
Once the protocol for tissue culture of cannabis is perfected, then we have no longer have to worry about mothers getting sick and passing on the sickness via propagation. Hopefully it will be sooner rather than later.
There is so much we don't know about this amazing plant it is astonishing.
We don't even know for sure if it is truly dioecious !!!
