Light intensity decreases at a square.

Double the distance from the light source and you'll cut the intensity to 1/4
harris7 Reviewed by harris7 on . keeping light same height? what would happen if i kept my light the same height, about 20 in above plant, would the plant grow into the light? or would the plant slow its growth and become more compact? i have not raised my light and i am getting alot of secondary growth. thinking about raising it to get more vertical growth with the secondary growth. thanks Rating: 5
