Phase Duration
The number of days flowering facilities were used for a phase.

By default the flower phase is always associated with flowering facilities in yield expressions, simply enter the number of days the flowering photoperiod was used.

Vegetative and Propagation phases
Both phases are sometimes associated with flowering facilities. Most indoor crops are grown on a repeat basis, where other resources at remote areas often accommodate one or both of these phases. And because their photoperiods are incompatible with flowering, repeat growers make a choice between two evils....

Defaults for these two phases are set to the option most repeat growers would likely choose. But unlike the flower phase, these defaults can be changed, and the associations between phase, cycle time and resource usage will automatically change in yield expressions. Please see the Vegetative and Propagation links for more about choosing your option.
