Yes you need light to grow your cannabis and here is what you need to know about the cannabis plant light cycle.
Best light cycle for vegetative growth.
In the cannabis community light cycles are expressed as a fraction with lights on time over lights off time.
Additionally when plants are exposed to 18 straight hours of intense light they become stressed.
When the lights are turned off and no photosynthesis is occurring the plant can absorb new co 2 into its cells.
More metal and less plastic is always a good way.
While under light cannabis tries to prevent co 2 from leaving its cells by cutting off transpiration.
All of this growth takes a significant amount of light which is why the vegetative light cycle should provide between 18 and 24 hours of light per day.
There are two major cycles of growing marijuana.
In every phase your plants need 6 hours of direct full spectrum light each day.
However this prevents new co 2 from entering the cell blocking new growth.
Which light cycle is best for vegetative growth is an often debated topic.
In the vegetative stage your plants need about 18 hours of lights on 6 hours of lights off.

While the marijuana plants are in the vegetative growth stage they require a minimum of 12 hrs per day of light preferably metal halide grow lights which produce the white blue color light spectrums plants crave to grow healthy.
