There are two major cycles of growing marijuana.
Best light cycle for vegetative growth.
In every phase your plants need 6 hours of direct full spectrum light each day.
These are the vegetative stage when plants are growing and the flowering stage when plants produce flowers or buds.
In the vegetative stage your plants need about 18 hours of lights on 6 hours of lights off.
Cannabis light cycle basics.
Additionally when plants are exposed to 18 straight hours of intense light they become stressed.
Here we review the basics and explain why we prefer an 18 6 light cycle.
Lights are on 24 hours and off 0 hours.
The vegetative stage light cycle.
The best lights for this tend to be fluorescents.
While under light cannabis tries to prevent co 2 from leaving its cells by cutting off transpiration.
For vegetative weed growth you want a lot blue light which on the spectrum is between 5000k and 6500k which is what you need to look for in vegetative growth lights.
Don t want to worry about light schedules.
There are two stages of cannabis growth where it is important to strategically monitor your light cycles.
Many indoor growers provide 18 24 hours of light a day known as 18 6 or 24 0 light schedules during the vegetative stage to encourage faster vegetative growth.
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.
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.
The plant can receive as much as 24 hours of light a day while in the vegetative stage.
More metal and less plastic is always a good way.
Yes you do want to look for a grow light that is very durable.
The light your plants get throughout their entire life cycle will have a tremendous impact on how much they weed they produce.
When the lights are turned off and no photosynthesis is occurring the plant can absorb new co 2 into its cells.
Vegetative stage this stage hosts the chemical reaction that converts light and carbon dioxide into sugar.
The vegetative stage the flowering stage.
Seedlings do best with 24 hours of light.
Knowing the importance of light cycles for cannabis before even making your first move is as important as looking for the perfect growing soil for your plants.
In the cannabis community light cycles are expressed as a fraction with lights on time over lights off time.
Growing marijuana indoors you need to know the best schedule to set your timer for the vegetative light cycle to come on and turn off.
Yes you need light to grow your cannabis and here is what you need to know about the cannabis plant light cycle.
