how long does it take for seeds to break through the soil

So I put the seeds in paper towels until they cracked and had little roots then put the 1/4+- inch deep in soil and covered. Anyone have an idea how long it should take them to break through the surface?

you could see some coming up by tommorow they sprout pretty fast yesterday i checked mine and i had 4 sprouted and within 2 hours another one came through.

day 2 at most.Make sure yu dont pack the dirt on them just brush the soil back over them lightly

hmmm I put mine in last night, so I'll wait until tomorrow morning before I get nervous.

They need to go under light as soon as they sprout right?

I actually used a spray can and misted enough water over the soil to get it to settle a bit. is that ok?

i keep them under the lights before they even come up dont get nervous some just come up faster then others i planted 3 days ago and there still comin up. just keep it moist and humid and about 75 and u will be golden

or grab some rockwool place seed in middle water a bit then grab a 2 ltr.bottle and cut off the bottom mist inside place over rockwool keep moist near indirect booyah!! 3 days tops for me if not i check inside rockwool to see sprout.

I have trays with 15 cells in each, and in order to keep them moist, I just put ceran wrap over them. Its not air tight but ought to work.
