Mosspole dripper, to water your mosspoles slowly without spilling water everywhere. It works with round and D-shaped Poles and even with a garden stake. It works via a wicking cord. make sure you chose a wicking cord made for water, because those made for wax dont work that great.
The wicking cord I use (https://www.amazon.de/dp/B07HWSQB5B?ref=ppx_yo2ov_dt_b_fed_asin_title&th=1)
The bottom diameter is 58mm and the diameter for the wicking cord is 5mm.
