Plants have been topped around Day 30. Also applied a little bit of LST. Both are looking good.
Had the growbox inside the cellar with ~15°C. This was a little bit too cold for them, so i moved the Box back into the House again.
At the start of next week, I'll repot them into bigger pots.
@FlatBrainGrower, a change would only make sense if you repot them to 20l pots. I would start with 11l or 12,5l Airpots the next time, but this is the maximum condiderung your tent size.
