I am still on holiday. My irrigation system seems to work. I can only show you a video from my Blink in the greenhouse, showing 24 hours from Friday to Saturday. Tropical Mirage is the cannabis plant in the front; she seems to be well. You can also see Euphoria in the back and right in front a giant basilicum hybrid and a Lila Luzi chili plant. Next sunday, I will be back with a more detailed report. Meanwhile, I am testing a few new strains in coffeeshops in Den Haag and Amsterdam :-).
@timbarin, I have bought a Gardena Set for pot irrigation: https://www.gardena.com/de/produkte/bewaesserung/micro-drip-system/tropfbewaesserung-set-terrasse-30-pflanzen/970653301.html
Maybe you can find an English version. It is available at Amazon.
It basically consists of two different sized tubes, which you have to cut according to the distance of your pots; at the end the get a combi element of extension and dripper, so that you can reach all plants. There are several good examples in the manual sheet.
The water comes from a Gardena water distribution system (1197-20) and controller (1892-20), connected to a water tap in the garden. Unfortunately, my system probably stopped working two days ago (I could see it in action on my electricity controller). My neighbor is watering now :-) I will be back on Saturday and will post some more details of the problems in my reports on Sunday. Hope this helps.
