Tropical Mirage is growing nicely in the greenhouse. Because I had a major attack of thrips and gnats on my larger plants, I preemptively treated the soil with nematodes.
@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.
