Hi Guys

So I bought a starter kit with various seeds and followed the instructions to the note.

My query is though my pot with the japenese black pine has 4 chutes sprouting and don't know what to do. Should I be repotting these into separate pots, taking off the seed casings off the top or just let them be? I've uploaded pic hopefully this helps.

Sorry should have mentioned these are nearly 4 weeks old and yesterday I only had 2 chutes I could see. Dont know if this makes a difference but I've been keeping them at a window facing sunlight below a radiator with intermittent heating in Scotland.
