How long for seedling to grow?

3 days. After a week give up. You can carefully dig down in the dirt to find out what happened. Occasionally, you'll find it and it was just having trouble breaking the surface, you can open it up and it will recover. Good luck!

It takes me 3 days for seed to sprout above medium. In a humidity dome temps 75-80 degrees and humidity 80% 3 days every time you can check out my new seeds sprouted after 3 days I plant another seed 3 days later sprout time. My ogkz is exactly 3 days behind the rest .

Heya! I find it takes 1-2 days for germination to show tap roots. Once planted another 1-2 days to sprout out of the soil. From there on the growth changes very very quickly and explodes. If taken care of, will double every week in size until later veg. Cheers!
