3 week growing marijuana then light swith

A question from a fellow grower:

How big will my plant get after 3 weeks veg from seed and switched to 12/12

Not very big. This is all dependent on what, You do to and for the plant.

Everyone grows differently with different lighting , indoor/outdoor, etc, etc… Letting us know what you are doing and using will help us to give you a more educated answer In the future. Good Luck :slight_smile:
