What are the methods of inducing crystal formation?

The first thing is by "scratching" or rubbing the flask with a glass rod or metal spatula. A second tactic is the use of seed crystals. Taking just a few crystals from the previous crop and putting them in your solution will promote the growth of more crystals.

What did they do at the first harvest?

At the first harvest, they pick whatever fruits or vegetables are at the appropriate point of ripeness. It depends on the crop. With a crop like hay, when the hay is at the appropriate height, they run the machine through it, cut it, and bale it. With cotton, they pick the bowls when they at a little over 2 inches. Then the second crop grows. With peaches, they pick the first crop so the second can grow.
