My First Grow

Good morning everyone! This is my very first grow and I am more than certain that I am going to do a lot of mistakes so don't mind to give me some tips if you're following this grow. So I decided to not let my seeds germinate in water & paper towel, instead I used growing earth with almost no nutriments and watered them with rain water. After 3 days, 3 of the seeds germinated and started to show leaves. I used a germination box as temps and humidity were very low.
