I just transplanted my girl in to a bigger container. Perlite and soil. I made a little humidity dome because it's in the basement and it can get cold, around 12-14°C.
So the humidity dome in theory traps in some heat and moisture that is created from the light.
She is growing slowly and very short, but she has 3 nodes already.
I also gave her nutrients for the first time. Just a simple 20-20-20 to get things growing.
