When does it grow??

I couldn't find much on this or maybe I was looking in the wrong place.

Does it grow more during the dark period or light period during flowering?



I would think the light period would produce more growth, but I've read people have seen their plant grow inches overnight.

Just curious.

They collect energy when it's light and metabolize it when it's dark. Mine are in week 2 of flower and are growing 2 inches every night.
