Hell, I'd do it just for side income on top of my actual job, it's not like you need to sit there and watch it grow.
Depending on the strain...you kinda do. At least, in terms of regulating temperature, insolation, testing pH and soil nutrient balance, and safeguarding against disease, parasites, and insects. Remember, a lot of these high-yield, high-concentration strains that are popular today have been kept as far from the ravages of natural selection as humanly possible for decades' worth of generations, meaning while their yields are consistent and highly marketable, they ain't robust.
Addendum: funny story, in high school one of the guys in FFA designed a modular, portable, collapsible single-piece hydroponics unit that was vertical farming-ready, and built a working prototype for my high school's agriscience fair. Each unit had its own filtration, pump, timer, and grow light operating off a single power supply that could be daisy chained to other units, and isolated/quarantined at the pull of a lever in case of outbreak. Damn thing was built entirely out of materials you could buy at any local Wal-Mart or hardware store, and he somehow figured out how to make the thing with a stupidly-low price-per-unit, like less than thirty bucks each in mid-'90s dollars.
It was absolute fuckin' genius, he could have patented the thing and probably won a Nobel prize marketing it to starving third-world countries or some shit. Instead, he built a bunch of his hydroponic Legos at home and started growing weed. Surprise of surprises, he got busted for possession of a
lot of fuckin' weed not even six months later because the idiot was selling at school and on field trips which made him easy to track down and catch. When he got busted was hands down one of the absolute funniest things I'd ever seen in high school, it was like some Heisenberg shit.
