Additionally when plants are exposed to 18 straight hours of intense light they become stressed.
Best light cycle for vegetative growth.
The light your plants get throughout their entire life cycle will have a tremendous impact on how much they weed they produce.
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.
There are two stages of cannabis growth where it is important to strategically monitor your light cycles.
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.
Here we review the basics and explain why we prefer an 18 6 light cycle.
When the lights are turned off and no photosynthesis is occurring the plant can absorb new co 2 into its cells.
Cannabis light cycle basics.
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.
Which light cycle is best for vegetative growth is an often debated topic.
More metal and less plastic is always a good way.
Make sure you have a room perfect for the light cycles an enclosed room without light leaks would be very perfect when you have this clear you may have a well fed healthy plants ready to grow for you.
Lights are on 24 hours and off 0 hours.
In the vegetative stage your plants need about 18 hours of lights on 6 hours of lights off.
Seedlings do best with 24 hours of light.
Yes you do want to look for a grow light that is very durable.
Yes you need light to grow your cannabis and here is what you need to know about the cannabis plant light cycle.
The vegetative stage the flowering stage.
Vegetative stage this stage hosts the chemical reaction that converts light and carbon dioxide into sugar.
Don t want to worry about light schedules.
For flowering you should switch to a 12 on 12 off schedule.
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.
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.
In every phase your plants need 6 hours of direct full spectrum light each day.
The plant can receive as much as 24 hours of light a day while in the vegetative stage.
However this prevents new co 2 from entering the cell blocking new growth.
There are two major cycles of growing marijuana.
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.
These are the vegetative stage when plants are growing and the flowering stage when plants produce flowers or buds.
