The photos were a bit slow loading, I only saw the closeup of the seedlings in the cups (someday I will convince people to stop using cups and smooth pots).
Take em out of that bin as well they need to fight for themselves, they don't need a humidity zone, and will do better dryer, trust me, you need to not water it for like 3 or 4 weeks before that seedling will keel over and die. You can make the most difference to a weed plant in the first 10 days after germination, by focusing on growing roots and forgetting there are even tops connected,
