4. Plant nutrient dispenser (a bunch of peristaltic pumps to measure out a specified dose) 5. A wifi-attached thermostat with a 4-colour e-paper display and simple, physical controls (I'm trying both a rotary encoder and a magnetic angle sensor with a "dumb" wheel that has a magnet embedded in it, I also considered doing something truly out there, like a retractable string that you pull out and attach to various hooks on the wall at regular intervals to indicate what temperature you wanted)
