Hey everyone,

I heard about windowfarms a while ago and now time has come and I want to build my own. There’s a big balcony door in my apartment next to a window. It’s on the sunny south side but without much direct light. Because my desk is in front of the window and there’s less space I want to use the balcony door. The problem is I am not allowed to drill in the door. I found nothing about other windowfarms hanging at a balcony door. You think I can hang 3-4 columns on the door with hooks like in the picture? How much weighs 1 column with 1,5l bottles?
