Dryback what is the percentage?

Hellooo, In coco/perlite 70/30 the dryback is more about steering the plant than hitting one fixed number. With your Bluelab Pulse you’ll quickly see that after full saturation (field capacity) the media usually sits around 60–70% moisture. A common practice is to let it dry back by about 30–50% of that value before re-irrigating, depending on the stage: Veg / early growth: keep it a bit wetter, 20–30% dryback, so roots can spread easily. Mid to late flower: push it further, 35–50% dryback, to get stronger oxygenation in the root zone and better generative steering. Just be careful not to let it get bone dry, because coco loses structure if it dries out too much. The sweet spot is to keep a rhythm where the media always re-saturates well, but the roots also get plenty of oxygen in between 👍Have Fun and happy Growing.
