I would want ideal plant growth, while testing for taste.
Seeds can germinate with paper towel and some water, I wonder how direct you could get it to sprout, some rock wool maybe. A filter for the bubble air pump. The more variables you can control the more you can test for.
Light amount, spectrum, time of day.
pH of water
Oxygen water & air
CO2 water & air
Circulation amount water & air
Nutrient amounts
A different spectrum of light at times of day, a light at 60Hz and our eye doesn’t notice it blinking. Wonder if photosynthesis acts the same as the reactions in our rods/cones and it stops mattering at a certain refresh rate.
Lighting, I have a very large grow LED and liquid cooling, better with a large fanless heatsink.
Hydroponics, I have the 3″ mesh pots.
Needed:
ph sensor, ph up and down
liquid nutrients
a way to circulate air, I have a few pumps which may do
germinante seeds, rock wool may work
