no just one, if you're looking at that white tube in the BG its just the wire for the thermometer. I was checking soil temp. it's at 29C. Soil doesn't look very wet in person only poured a teaspoon of water earlier in the day over the surface before the seed sprouted.It looks fine.......all new sprouts are pale until they've been under the light.
Your soil looks very wet.
Also, are there two plants in the same pot?
