<span class="link_user">@JonEm</span>, Hey! tried once fabric pots but the lack of rigidity was a no go.
For airpots, after cutting plant, the density of roots is impressive. 0 root tapping! Some say a 6l airpot is equivalent to a 12l plastic pot.
<span class="link_user">@Janjo94</span>, I have no idea why so small. It is otherwise looking healthy. The growing environment conditions were OK but maybe should have introduced nutrients earlier. Although it doesn’t appear there is any sign of a specific deficiency. It was slow in the beginning and didn’t grow much more vegetatively after starting LST. There are a few decent size colas so I will get some harvest out of it. I will update photos soon.
