Hi hope this helps I’ve been reading a few articles aimed at tissue culture and preserving plant genetics over long periods of time
This is also a helpful article https://www.plantcelltechnology.com/pct-blog/the-future-of-cannabis-cloning-tissue-culture/
The beauty of TC is that unlike conventional methods, it lets cultivators preserve a living specimen, almost perpetually, through minimal effort and using minimal space. Small pieces of plant tissue, even just a few cells, from cannabis specimens can eventually produce hundreds of identical clones.
All tissue cultures start life as a small cutting from a sample. The tissue sample is trimmed and goes through a crucial sterilization process. Once cleaned, the plant tissue goes in a dense nutrient culture which is typically an agar gel containing a carefully crafted nutrient, hormone and sugar mixture. The tissue culture controls the sample. Different hormone mixtures will trigger various stages of development for the tiny culture.
The culture can technically remain in a period of indefinite purgatory, until a time when the grower wishes to work with the sample again. Through the introduction of new hormones and nutrient-rich growing solutions, a cultivator can trigger growth, root development, and multiplication. When the plant is large enough to multiply, it is ready to be trimmed into literally hundreds of separate yet precisely cloned individuals.
These hundreds of samples follow a similar course until they are large enough to enter into a phase of hardening off and ready for planting. From one small tissue sample, a well-organized cultivator can potentially create hundreds of perfect clones, without any contamination from the mother.
