Indoor Marijuana Grow Lights Tips and Secrets that will help you with growing your cannabis, as well will help keep the grow lights in good working condition.
Controlling Marijuana Growth using Grow Lights
The life cycle of the cannabis plant is determined by the daily photoperiod (hours of light per day). Natural sunlight is the best form of light for growing cannabis plants, although their life cycle can be controlled much easier with artificial indoor grow lighting.
A marijuana plant tends to grow faster if it is grown under continuous light for the first two months of it’s development.
Lamps should be kept as close as possible to the cannabis plants, they should never be allowed to touch the cannabis plants.
The Best Grow Lights for cannabis plant growth emits high intensities of the blue and red bands of the light spectrum.
Fluorescent light is one of the most effective source of artificial light readily available to home growers.
Metal Halide lamps are better than most fluorescents, because they radiate more light in the blue and white bands of the light spectrum.
If your grow lights are too hot on your hand, they are also too hot for the plants leaves and need to be moved up higher or put on a light rail grow light mover.
The amount of light you supply your cannabis plants depends on the size of the garden, but at least 20 watts per square foot is recommended.
Metal Halide lamps are generally considered a better light source for marijuana vegetative growth, they use a lot more electricity than fluorescents..
Grow Lights for Growing Large Marijuana Plants
Under artificial light, a cannabis plant can grow from three to six feet tall in 2-3 months.
cannabis plants entering the vegetative stage enjoy up to 24 hours of light per day, while twelve hours is required for flowering.
The more light you give your cannabis plants, the faster and larger they will grow.
Lamps should be fixed to the roof in such a way that they can easily be raised as the cannabis plant grows in height.
The use of reflectors ensures that the light is spread more uniformly around the cannabis plants.
Use a fan to cool down your cannabis plants if the lights in a small grow room raise the temperature too much.
cannabis plants grown in conditions of varying daily light patterns will not settle into a regular life cycle and will grow poorly.
If there is not enough light in the grow room, the marijuana plants will often grow tall and thin, in search of the light.
Do not “wake up” your cannabis plants by switching on the lights if they are in the dark period of their daily light cycle. Use a green-colored light bulb as an emergency bulb in your room.
cannabis plants grown with a long daily photoperiod, will require more frequent watering than those grown with less light.
Incandescent, or screw-in light-bulbs are usually not suitable for cannabis growth, although they can be used with fluorescent tubes.
If the edges of the leaves near the lights and growing tips start curling up, it usually means that they are getting too hot.
A cannabis plant will grow with as little as six hours of light per day, but requires more than twelve hours per day for good strong growth, 24 hours is my recommendation.
A cannabis plant grown with insufficient light may sometimes develop disfigured leaves with only one or two blades per leaf.
Paint the walls, floor and roof of your grow room white (use a flat white) for better reflection of light onto your growing cannabis plants.
cannabis plants require twelve hours of light per day for at least two weeks before you can expect to see the first signs of flowers appearing.
Never increase the daily light photoperiod to more than twelve hours, once your cannabis plants have started flowering.
A cannabis plant grown indoors with lots of light will often grow larger and more potent than a similar cannabis plant growing outdoors in natural light.
To increase the amount of light available to the lower branches, you could mount extra fluorescent tubes vertically, onto the walls of your grow room and keep the water leaves trimmed, allowing more light to reach the bottoms of the plants.
Grow lights and replacement bulbs can be costly if not taken care of!
