When it comes to seedlings, light is the most important factor to consider when starting them out in the world. When the light is too strong for the seedling to see, it is visible in the growth of the plant. This is why when you start them with the most simple things, like a lightbulb in the room when they are born, they will be able to survival in the dark.
But what about when the light is too weak? That’s when the seedling might get blinded by the light and die. To avoid this, you need to light up the room when they start to grow, so they know can’t be blinded by the light.
