I am super pleased with this grow thus far!
She's definitely shorter and bushier than the African Amnesia but seems to have caught up in terms of rate of growth.
The last week was a challenge regarding temperature control with night temperatures, outside the tent, dropping to zero on some mornings and the single 100w ceramic heat globe was not keeping up... I switched to a 24h light cycle which managed to keep the lowest temp, inside the tent, at around 11°C - which is super low. The plants have been purched on a heat mat for their entire grow which is keeping the substrate at a respectable temperature, which I believe is the underlying factor of their continued growth despite the harsh temperatures.
I have now added a second 75w ceramic heat globe which seems to be holding the temperature above 17°C.
Day temperatures are still perfect, ranging between 24°- 28°C.
Humidity is low - between 30% & 60%.
If you actually read all of that, you're a legend!
Happy Groing
