Heyyy thx for the comment :) I didn't recognized the water bc while winter the water is turned off in the whole community garden so I just recognized when turning it on the first time of this year (fortunately) ^^ I'm so glad that I found the issue and a reason to rebuild that part of the house in 2021 xD Yeah I need to be busy I guess - my girlfriend is having her chilly and lazy days since months now and I am starting all over haha
