Day 65: The lower branches of all 4 cultivars have been cut (they were carrying small buds, judged to be unsufficiently lighted).
Watering: 5l total dispatched between the 4 cultivars + 2.5 ml/l Bloom + 1ml/l Ca Mg
Day 67. As soon as the fan is blowing, the humidity reaches 93% 95%, espacially in the first 3 days after watering. Opened the tent's door halfway in order to reduce humidity to a reasonable level especially w/ buds already formed. The tent is closed when fan is stopped.
