I'm growing magic mushrooms and hiding it from my parents
Why are you trying to hide the mushrooms from your parents?
Otherwise, my parents will get angry with me.
At your age it's common for kids to hide stuff like this from their parental figures. Have you thought about trying to grow them somewhere else?
This is just my first time growing them, I didn't know they grow up so fast.
While it is normal to be curious and want to experiment with hallucinogens, it would be wise for you to be careful. There is a reason your parents would be concerned if hey found out you are growing hallucinogenic mushrooms. Perhaps you should do some research into the dangers of the mushrooms before you continue growing them.
