Tropical Mirage grows very slowly. I probably overwatered and overfed her in the beginning, but now I added a little Alga Grow, because I suspect the slow growth is now caused by a nitrogen deficiency. I am still not sure, whether it is over- or underfeeding :-( But at least she looks healthy now. Let us keep our fingers crossed that she accelerates her growth in the next days. The weather last week in my region of Germany was cold and rainy, so I kept the plant in the greenhouse. This does not help either to give her a growth kick.
@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.
