Willeke, They will thicken up over time, but will probably be taller than others. Just watch them and see. I usually find that most seedling start to come up on Day 5, sometimes a bit earlier. Then the others come afterwards. I like to take them out of propagator and have under my lights, once there are about 50% of them germinated. Then I just keep the top of the grit or soil from drying too much.
