How many lights do i need for commercial marijuana growing? 2020 Updated
For the many growers who are unable to cultivate cannabis outside in the free abundant sunshine, grow lights are necessary to successfully grow cannabis indoors. Commercial LED Grow lights take the place of the sun, and power the growth of your plants and their buds. Light is like “food” for your plants, so without a lot of bright light, even a healthy cannabis plant won’t produce much bud at all.
In the absence of natural sunlight, grow lights for marijuana play a critical role in indoor gardening. Light is necessary to bring about photosynthesis, during which water, carbon dioxide, and light provide the energy source for plants to produce glucose and oxygen for their growth. As you search for a suitable grow light for weed, you should first consider the following:
Different light sources provide different colors, each with varying energy outputs and wavelengths. Plants need more blue light during the vegetation phase and more red light during the flowering stage. Blue waves tend to be smaller and possess more energy whereas red light waves have a longer reach but with less energy output.
When growing cannabis, the vegetative stage of plant growth requires a longer duration of light than does the flowering stage. Some grow lights have built-in timers for light cycles (automatically turning on/off lights at set times), while more basic grow lights (without this capability) will need a timer.
In general, each cannabis plant you grow requires at least 1sq ft of space. After germination, I like to pot one plant in a large 5 gallon fabric container, which has a diameter of roughly 1 sq foot.
