Besides just sitting there and watching them grow, I also started working on my first Arduino circuit and program so I will be able to just check my 'grow computer' - if the humidity is right in relation to the current temperature and grow phase - instead of doing it with a VPD chart all the time by hand. Later it should also trigger the necessary equipment via relais by itself.
Plants went with the coco they germinated in right into the final soil to minimize stress.
