Did my first Cannabis TC more then 20 years ago after I self taught myself and bought all the needed lab equipment and set up a small in-vitro lab.
I found it pretty easy to Clone in-vitro meristems, Callus even easier, but I did have trouble getting the Callus to shoot after rooting. Rooting is easy.
Growing meristems and Callus is easy, so is sterilizing a clone so you can stick it in agar and nutrients to grow.
Give it a try, it is easy, and if anyone figures out how to freeze Callus or Meristems and then thaw them out and re-grow them please let me know, that was my real interest in the first place. When I did it they were reduced to black slime lumps, zero life...
As for freezing, I had a professional In-vitro Company try and find a way to freeze meristems or Callus, but after a few years gave up, I still think it will be done by pretreating the Callus or Meristems or other newer protocols in use today that we did not try.
My dream was a library that would maintain varieties or unique individuals in a very small space, for very long times, that could be re-grown if needed. Keeping clones alive is such a pain and waste of time, space and energy. Freezing would be great!!
