a lot of dependencies in the answer:

How many plants per pot?
How old is each seedling before it is counted as a "plant"?
I can make an aragula seed shoot in two days. I'll be harvesting in three weeks. In one square metre I can have well over a thousand plants on the go. I've done this. How many plants can I produce in a year? How many seeds ya got?

There're lots of examples of prior art local to me, if anywhere else that has a mains electricity supply, and that's pot farms.

Here, they tend to explode as people use halogen lights at silly power densities (like 6kW/sq.m) and lag the shit out of their lofts in an attempt to conceal them from police helicopter FLIRs, then wonder why they catch fire.

My first hack: built a motorised table for my mum's Singer sewing machine, came complete with foot operated beltdrive for the flywheel.
My second hack: built an automatic typewriter head cleaner, which was basically similar to an electric toothbrush. It would "walk" the keys one at a time, cleaning the heads as they came up.

More recently, I've just finished building a server inside a wooden footlocker. Weighs a LOT but boy, is it ever quiet - even considering it's got five fans and five hard drives in it.

if I had an SSD instead of a spinny thing, I'd be running all swap ops on an SD card. They're dirt cheap (8GB for what, three quid these days?) and swapping out a dead one is a simple case of press until it clicks and wait until the spring ejects it. Hell, you don't even have to power down to do it.

I already use such a system on my home terminals. Everybody has their own SD card (a key, if you like) that contains their OS-of-choice and workspace. No matter which system they plug into, their dekstop and settings look identical and even if they were plugged in remotely, if there's an internet connection available they'll connect to the home shares. The exception is my laptop and my netbook, both of which have internal persistence (hard drives) necessarily because I also administrate the file services through them.

Always look over your shoulder because everyone is watching and plotting against you.
