Hi SummerGlow -
I've done a fair amount of flasking, and it's actually not toooo difficult to do at home if you're willing to spend a good amount of time (or quite a bit of money) to get prepared. I started off by building a sterile glove box, and it worked just fine... cost $50 or so, I'd guess, but took time to construct.
Mixing the agar medium isn't hard.... it's just like mixing Jello-O. Add some boiling (pure) water to some powders, and put them in the flasks before you pressure cook them or autoclave them. The trick is getting the seed into them and keeping the flask sterile
Again, not too hard with the proper equipment.
On the other hand, that's just for sowing seed. Even for people who do a good amount of seed flasking at home usually can't do cloning. The process involves a sterile environment and disecting microscope (also sterile), as well as an electric agitator to keep shaking the flask while the protocorns develop... all said, it's pretty advanced stuff for a home lab.
BTW, the Arditti book (last time I looked, which wasn't in the link above, I admit) costs a fortune!
