DBQushanswered grow question a year ago Was pretty sure someone had already said this, but doesn’t seem to be the case.
The seedling stage normally starts when your seed breaks ground and opens its existing “baby leaves”.
And the end of this stage/start if veg is normally considered to be when your seedling has 3 nodes.
In my ongoing grow, It took 3 days to germinate and 10 days to transition from seedling to veg after that 🙏
