Lighting to grow marijuana seeds is extremely important to ensure that the cannabis plants reach maturity, because when it is grown indoors the sunlight has to be replaced. Simulating sunlight is done with different types of lighting to grow marijuana seeds, but it is not normal household lights. The lighting that is used can be metal halide, low sodium or even florescent lighting. The reason is they have the hot and cool rays that simulate the sun and help grow marijuana seeds to their fullest potential.
Sunlight for indoor plants that come through windows is not near enough light and when using simulated lighting the cannabis plants will have hours of light and hours of darkness when this lighting is turned off. This allows the cannabis to grow just as it would if it was planted outdoors, but without the threats of weather, bugs and pests.
The largest concern is having the right amount of light and for the exact amount of time the cannabis plants need it. Growers that buy the strain to grow marijuana seeds, they want should order the indoor weed knowing that they will have to provide lighting for the amount of plants they want to grow.
