A substrate management technique where the growing medium is allowed to dry to a specific moisture percentage before the next irrigation event, used to steer plant growth between vegetative (wet) and generative (dry) states.
Dakota targets a 30–35% dry-back in the coco before restarting the irrigation cycle. The Pulse dashboard monitors VWC sensors and triggers the Open Sprinkler when the dry-back threshold is reached. He notes it was a steep learning curve to dial in the timing.
