If you’re not familiar with TCP, it is basically a way to rid a clone of bugs, disease/viruses, and “rejuvenate” it in a sterile sugar-based medium, create hundreds of clones in a very small space, and retard growth for easy storage. For people that pop seeds all the time this is probably of little to no interest, but for people that are trying to maintain large libraries of living genetics or that want to restore vigor to 20 year old clones, this is potentially a miracle.
Rather than spend any more time with a half-ass explanation, I have attached one of the better videos on the subject (that I’ve found, at least) that you can peruse at your leisure.
TCP is really cool, even if you’re never going to do it yourself. Be sure to check the video.
