Hello my friend
Do not worry it's normal the first 10 days the seedling grows slowly after all accelerates 😉
Optimum conditions are 23 degrees and 70% humidity. For light I advise you a cycle of 20/4 is the one that offers the best performance for autoflowering. 👍
If you need advice do not hesitate good luck for your culture 🌱
May the strength be with you 💪
