Day 15:
For the first time addition of fertilizer to the water (2dl). Humidity varies between 55% and 65% during light period, and 60-70% in the dark.
Day 16:
I heap some soil around the stem for stabilisation. The plant is actually longer than it looks.
Day 17:
I reassemble the air tube. Now the air is blown out of the box instead of being blown in. Humidity and temperature drop (52%, 22 degrees).
Day 18:
I give 3dl this time. I cover the soil with aluminum foil, which increases light penetration and keeps the soil moist. The internodes are short. hopefully it stays that way.
Day 20:
Starting LST (low stress training). I hold the big leaves together with a brace so that the side branches get more light.
Day 21:
5dl water (after two days without).
Power consumption this week:
55 Watt, 18 hours per day,
5 Watt, 6 hours per day
