The Importance of Light in Growing Cannabis

Light is a very important factor needed for growing marijuana seeds. The sun is the best source of light but if you are growing cannabis indoors, artificial lights are necessary to support the plantsí growth. In growing indoors, choose a kind of light that will allow the marijuana plants to grow to their fullest potential in order to obtain high yield and potent buds. Since the growth cycle of weed plants depend on the hours of light they are receiving, the artificial lights give growers the flexibility of inducing the plants to flower whenever they want.


What are the different lights you can use to grow marijuana seeds?

The sun is the source of light when you grow cannabis outdoors but in indoor growing, artificial lights are needed. Among the most efficient types of lighting used for growing marijuana seeds are high intensity discharge lamps such as metal halides and high pressure sodium lamps. LED grow lights are also best to use because of the little heat emitted while providing the right blue and red spectrum of light. CFLs are also good to use if you are growing a small number of marijuana plants. Fluorescents are also popularly used in the early 80ís but this kind of light is emitted over a large area. You may need to install a reflective material so light is focused to the plants and not just wasted.


How much light is needed in growing marijuana?

There are different lighting types that a grower can use for the marijuana plants and each type of light produces different intensity of light. As much as possible, mimic the light coming from the sun to ensure that the cannabis plants will give you big harvest. Use grow lights that produce more of the blue spectrum during the early stages of marijuanaís growth until the vegging period. For the flowering stage, the plants need more of the orange and red spectrum. During the vegetative period, cannabis plants need as much light as they can to grow fast but less light is needed as they are about to begin the flowering stage.
