I transplanted the girls to 11 liter fabric pots on day 28. In case they have to finish outdoors, I spray painted them greyish with some white paint. After the transplant I added 22 grams of Biogrow as a top dressing in each pot. I have trained the 4 branches a bit outwards/downwards to get some more main shoots.
They are still both allowed to stay in the tent as there is just enough space for them.
@Mrs_Larimar, I don't know to be honest. I don't think paint on the outer layer of the pot will damage the plant. But we'll see, I currently have 4 plants in painted pots.
