Siwa world without Open Air Farm

[zgrssd]

I started a game on a Siwa class world. The world is fully suiteable for Open Air Farming. There was a lot of space for open Air farming around the city.

Yet the starting Farm is a Agriculture dome, wich porduces barely enough for my existing military of 1 army.

I noticed that I have 18 RAD on the City hex, maybe that caused it?

More likely it is the average temperature of the Hex

If it was temperature, then the Xenofarm should still work or not?

Temeprature is 34°C in winter. Tropical planet avereage is 39/40°C.
32°C Planetology temperature, 11° axis tilt.

Xenofarming usually can survive a wider range of temperatures compared to Terran farming. In my experience.

Check the xeno crops agricultural details in the help tab. It's possible to roll a completely flora covered planet with edible crops suitable for a very atypical temperature bracket for that planet. I had a world with -30 - 20'C and xeno crops being barely growable at the poles with optimal temp around -50'C and max barely coming to those -30'C.
