The Importance of Complete Darkness to Cannabis Flowering
As we know, cannabis has four growth stages: seeding, clone, vegetative and flowering, different growth stage needs different hours of light and hours of darkness.
During the flowering stage, we need to ensure the true 0-10V dimming, as the flowering stage occurs naturally when plants receive less than 12 hours of light a day. For cannabis to completely enter the flowering stage it requires periods of 12 hours of complete darkness.
Also, when i see Mars Hydro Amazon's comments, there are many customer complaints are dim glare when the light turn off, the Amazon customer also said the dim glare is not suitable for bloom/flowering stage, please kindly check the below comments.
Why does the cannabis need darkness?
cannabis plants are “long night” plants or “short day” plants. This simply means that, for their hormones to be triggered into changing from vegetative growth to flowering, they need long periods of darkness without interruption.
How to create darkness?
You’ll want to confirm there is absolutely no light leaking into the grow room before you start the flowering cycle. Here is how you do that:
- Go into the room yourself, turn off all the lights, and close the door.
- Give yourself a good quarter of an hour until your eyes are used to the darkness, and then take a close look around the room to see if you can spot any light leaks at all.
- Double check beneath the door, the curtains, the dehumidifier, CO2 generator, and other such devices.
- Equipment with light-up displays will disturb periods of uninterrupted darkness. Cover those displays with duct tape.
- Buy true 0-10V dimming LED grow light
