It was always a big dream of me to grow a N. bical, but never possible for me because in Sweden it was to dark and now in germany i dont have space because my basement is full with highland neps.
So i thought about how i can grow a bical and dont spend much money for a setup.
I found a nice and cheap solution for my windowsill. The window get full sun for 6hrs.
Found PET sheet in a hardware store and build a small tube for a first test. When the bical gets bigger i can easy build one with 1m or 1,5m diameter and costs for the small one is only 15euro.
Here are some pics, plants are now inside the tube since 2-3 weeks and seem to start growing now.
