Hello and Thank you for the reply Daisyl!
Im growing it inside. I'm located in Berlin, Germany. Temperatures now are of 3 celsius at night up to 11 celsius during the day.
Do you have a suspicion of what it is? Do you think is safe to put it outside for such a catctus in these low temperatures? ANd if so for how long?
Attached here is a picture of the whole plant.
Thanks so much for helping!!
