About
A research project about why home food crops fail.
The detection window
A failing crop is measurable about three weeks before it looks like anything is wrong.
Day 0
Soil, moisture and timing have already decided the outcome
Day 19
The grower sees the first symptom and starts guessing
Timeline: the conditions that cause a crop to fail are measurable from day zero, before symptoms appear. The grower typically notices the first visible symptom around day nineteen. The roughly nineteen days between are what this research is about.
