GrowCNanswered grow question 4y ago I do not use the paper towel method. It is easy to over water and then it is very easy to damage the tender tap root when planting. I find it more reliable to soak the seed for 24 hours and plant it.
Looking at your photos everything is soaking wet. If the sprout got planted without damage it is possibly rotting. The jiffy pods look soaking wet, the towel underneath is dripping, you've got them under a humidity dome with max humidity and the temperature is high, not terrible but I would not let it get any warmer.
Your fan is not doing anything. It is blowing on the plastic humidity cover so it's not accomplishing anything. Also, you don't need both germination lights and your main grow light.
