Fertigation changes Favens increase the demand placed on your plants, which means you must provide additional resources to handle the increased demand.  Irrigation Volume A typical irrigation volume increase in plants is around 10-15%. This change will be easy to manage if you are using substrate sensors. The extra volume can be mitigated by extending the duration of your P1 sequence during stretch and ripening. During bulking, this demand can be met by pushing out your final P2 event later in the day.  Fertilizer The need to increase fertilizer input varies from facility to facility. We recommend starting at a 10% increase in EC input throughout the flowering process. If you feed at a 3.0 EC, increase to 3.3 EC and see how your plants respond. If you need to increase input further, then do so. We believe in a less is more approach. Be careful not to over-fertilize.
