Week 5 already? Plant is struggling to catch up after such that two week lag period where it didn't do a thing. Still, things are starting to get encouraging so now watering every day at 2 hours after lights on.
Added a webcam to the tent to watch what is happening. Noticed that at 12 hours after lights on, the leaves would start to wilt. Flooding at that time didn't have any noticeable effect before lights out, so I added a flood at 9 hours in (half the period). Pushed the wilting back to 14-15 hours after lights on, and just a little now, but still not completely solved.
Grew from 2 inches to 7 inches this week!
