I like planting the seeds myself when I'm doing the cross breeding thing - 5 on top, 5 on the bottom, top to self-pollinate, bottom to cross pollinate, middle for cross-bred between the two. (I'm very OCD that way..)

The CTRL-Z script is good for "mining" for big chunks of cash when you want to plant multiples of an expensive plant. It's pretty neat - first 5 seeds in the box goes to the top row, then 6-10 goes into second row, 11-15 goes in the third row. It does go through it pretty darn quickly so it can be pretty freaky to watch. *grin*
