Rehydrated bags day 7 with Jacks 321 at 2.4 EC + 5ml/gallon Calimagic+ 0.35mL/L RapidStart to help correct low CEC in coco and increase root density quickly. The label claimed the coco was pre buffered, I should have buffered it myself anyways.
Humidity lowered to 62-65%, aiming at 0.9-1.1 kPa VPD
Trellis net installed pre-empitively
Installed an Irrometer Tensiometer on day 13 in GG4 to monitor moisture level, nothing needed watered again after rehydrating until day 14
