Than check the coco prior to transplant. If you see bugs or smell forest or mushrooms than I would not recommend to start a plant in there. I can imagine that in Sweden it might be difficult to get some suitable coco or not you know better. If it is problem, than get some bricks, rinse them with tap with dose of calmag, than flush it with nutrient solution and than put a plant there. But before all of that do some research how to treat coco and than reconsider if you are able to invest that time and effort to follow that treatment, thats lot of time and water. BTW springtails are beneficial if they are not crowded, not sure about them in coco… instead of trying to get rid of them, if they are not causing issues, I would just let them finish and take mesurements before the next run. Good luck!
