Cannabis Grow Light
Why is Grow light important?Light is vital to photosynthesis, and thus essential to the growth of almost all plants. But, the specifics of how cannabis plants receive light are especially important.
For instance, photoperiod cannabis (non-autoflowering cannabis) grows best when it receives a particular amount of light hours per day, usually 16 or more, during the vegetative stage of growth. Once plants hit the flowering stage, that light requirement changes to around 12 hours per day. This, of course, is in line with the shift in sunlight hours that occurs in the spring, summer, and fall.
With that external signal, female cannabis plants (that haven’t been pollinated) know to start shifting their energy towards producing resin-loaded buds. If they don’t receive that signal, however, they won’t know how to distribute the energy they take in from the sun, and your yields will end up smaller than they otherwise would.
In turn, if you’re growing your weed plants indoors, it’s vital to ensure that your grow lights not only simulate the sun’s energy output, but shine on the same schedule as well.
The benefits of using LED lights to grow cannabis:
- LEDs run cool despite high energy output
- Less heat leads to decreased water usage
- Decreased water usage means more efficient nutrient usage
