ok it's almost 48 hours but what about in maybe 4 days?Dude you are going to need a few days to even tell. I would not disturb it.
Growing takes tons of patience. Your are just at the first stage and anxious, calm down a bit.
I did 1/2 inch from reading another source. I don't water it but just make sure the soil isn't dry on the surfacegive it a week atleast. then you can take some tweezers or something and remove a tiny bit of dirt till you find it ive done it before no problems. did you plant it shallow? like 1/4 inch is how far to go just enough to cover up the seed a tiny bit. keep a humidity dome on it or like a plastic cup upside down and just dont mess with it no watering or anything with the dome it will take forever for it to dry out you shouldnt have to water for like a week or two depending on your container.
