What's that growing on the wall?
China just announced it has finished building its space station. Here is a review of 11 launch missions since April, 2021 when the in-orbit construction began and how the station named Tiangong or Heavenly Palace in Chinese looks like now. (Video not complete due to time limit)

Device to detect orbital particles mounted outside China's space stationSource: Xinhua Editor: huaxia 2023-01-11 18:15:45BEIJING, Jan. 11 (Xinhua) -- A particle detector has been installed on the extravehicular platform of China's space station to obtain key data used for the space station's safety, extravehicular activities of the astronauts, biological experiments, and the study of space material.The energy particle detector in Wentian lab has been transported via the cargo airlock cabin, assisted by a robotic arm.The detector used a new material called CLYC for the first time in the world that can achieve high-efficient neutron detection.The newly-mounted device can monitor the energy and orientations of high-energy protons and electrons, heavy ions and neutrons in the space station's orbit, according to the National Space Science Center under the Chinese Academy of Sciences.
I understand that once a germinated seed breaks the surface of the ground it will naturally grow toward the light. That's how to control plant growth direction in zero-g. But what do they do when they plant a seed? There is no detectable gravity to tell the germinated seed which way to the surface. What is the mechanism to get seeds to grow toward the surface where light can then take over?
