Who did you consult with for the agronomy part of it? Does the system measure cues from the plants (NVDI etc) to determine water and fertility needs? Or does it just follow a recipe that dictates nutrient/water timing?

Also, what do you use for fertilizer? Recycling the N and Phosphate from astronaut waste and uneaten plant material would be ideal in terms of self sufficiency. Otherwise nutrients will eventually limit growth. And most of the fertilizers used in agriculture are corrosive, reactive etc so not ideal in space. Curios what the choice is there.
