FAQ
Questions GDU Accumulator owners ask.
- 01
What is a Growing Degree Unit (GDU)?
A GDU is a measure of heat accumulation used to predict how quickly a crop will develop through its various growth stages.
- 02
How can I predict my harvest date?
You can use the predict_maturity_and_harvest capability by providing the planting date, the required GDU for maturity, and a temperature forecast.
- 03
Does this capability account for environmental stress?
Yes, the calculate_daily_gdu capability accepts a stressFactor to adjust heat accumulation for conditions like drought or waterlogging.
