A reference sheet of breeding plants out there?

[Emia]

right now, I am in city living's apartment, trying to use fewest amount of plant for plant indoor. my objective is described below:

1. Eliminate trees from the plant form, as it clipped onto the walls.
2. determine the rules for grafting, as I've found some hybrid plants are missing its hybrid components when grafted onto others, giving the other just its base plant.
3. ratio of the hybrid plant's produce. so far, I've grafted hybrid plant with same amount of specie onto others.

well, for you apartment (small to mid sized apartment and not penthouse)gardeners, how do you go with your garden indoor? since space limitation really hurts me (I shouldn't fit a science lab equipments onto an apartment, I guess) I would like to ask anyone if they have plant combination that is good for apartment?

also, if anyone know where I can found reference for these mentioned above, I'd really appreciate it.

Have you looked through all of the wonderful guides written by this forum's Godfather Carl and his awesome crew?
Here's a link to the one about gardening. It includes a section on grafting. Hope it helps.

I've read that. That's why I ask.

Determining combination of each plant is really tedious, to be honest. If I could glance onto the game code for grafting, and understand it, I'd do that in a heartbeat. Alas, my programming experience is just from R, matlab, and such.
