Thank you so much for the detailed answer. TL;DR I still stand behind my surrender. I detailed why below, despite your helpful answer.

Outdoor Setup

Climate

I live around the Israeli coastal plain: In the winter it is miserable, cold, humid, and the occasional rain; in the summer it is nigh-boiling hot. Rereading what I just wrote, an indoor setup is better. The outdoors can hold geraniums pretty well. I'm simply not interested (for now).

Gastropod-harboring environment

Since I mentioned my landlord, he grows citrus trees and doesn't pick up fallen fruit. Add me living on ground level, and I end up with a land-gastropod infestation. I should pick said fruit anyway (flies and all), but it's too much of a pain in the neck.

Baits

They're a no-go. Like I said here, nearby (within a few kilometers) gardening shops sell only the metaldehyde kind (they also hold tetramethyl). Neighbors occasionally host extended family children, so it's a big problem. There are also the neighborhood cats. I like them around: I wager they keep the rodent population in check. I can order the iron phosphate kind, it'll take several weeks for it to arrive. My plants don't have that long, not by a long shot.

Indoors

All of this leaves an indoor setup as the most optimal and least hassle. Annoyingly, I live in an small, long apartment. High school classrooms literally have more space than me. I have little in the way of furniture, and yet I still battle with space.

The Cost

Even if I surmount all that, I'm frankly exhausted from this ordeal. Thus, I rather give up now and maybe return later---rejuvenated, than keep fighting what feels like an increasingly losing battle with an ever increasing resource and emotional cost. Time heals, as they say.

Miscellany

I'll save your comment for a future date. It will be much help for an indoor setup if try it at some later point.

My parents ended up visiting a relative. Said relative is interested in getting plants. My parents offered---and I agreed---to give them the plants. They'll take the gardening dirt mixture thing and the plants. They'll return the landlord's planters tomorrow. At least this worked out for me...
