You need appropriate amount of light for obtaining the high yield of marijuana. When growing indoors, if there is no light in your closet, you will have to provide the cannabis a lot of artificial light. There are mainly three types of marijuana grow lights available for the cultivators: Metal Halides, Florescent lights and high pressure sodium lamps. The growth of indoor cannabis plants largely depends upon the intensity of light. Florescent lights are reasonably cheap, effective and don’t emit much heat. Metal halides are expensive but more efficient than fluorescent lights. These emit more heat so ventilation is necessary. The metal halides require separate halides for functioning. High pressure sodium lamps provide the same output as metal halides but emit less heat. These require separate ballast and ventilation for functioning.

Lights For Growing Marjuana – Grow Lights
What are the best marijuana grow lights to use?
One can easily buy metal Halides and High pressure sodium lamps for growing cannabis indoors. These two types of marijuana grow lights emit more heat and are considered as best for growing marijuana. Metal halides emit white light and these are used where natural lighting is required. High pressure sodium lamps emit pink light. These are more proficient than metal halides as these consume less energy. High pressure sodium lamps have no adverse effect on the vegetation and these encourage faster plant development during the vegetative as well as flowering stage. When choosing for marijuana grow lights for your garden, we suggest a combination of metal Halides, high pressure sodium lamps with fluorescent should be used in cloning and early seedlings. It is also important to choose for best shades. Some of the lights are better reflectors; consult a good supplier to recommend the best light to suit your requirements.
What are the tips for using HID lighting for growing cannabis indoors?
When it comes to the tips of using HID lighting, the lamps and fixtures use to emit light should be hanged according to their sizes. The smaller wattage system (100-250 watt) should be hanged about two feet from the top of the marijuana plant. Medium wattage lighting systems (400-600 watt) should be fixed about three feet from the top of canabis plants. Considering the high wattage light sources usually 1000 or more, the bulbs should be placed at least 4-5 feet from the cannabis plant. Using the marijuana grow lights also depends upon the type of cannabis plant. Some of the plants need 10-12 hours of lighting to promote their growth. Several types of marijuana plants exhibit their growth improvement if lighted for 15-16 hours daily using artificial lights.
What is the cost of marijuana grow lights for high yield?
You should think about energy costs when choosing what type of light to use. A 400 watt HPS will provide an output of about 45, 000 lumens. This will cost approximately $20 monthly as electricity costs for every 500 watts which are continuously used. With the quick calculations, one will see that after monitoring the price of electricity, the ‘cost-effective’ or ‘cheap’ metal halide lights will be costlier than High pressure sodium lamps. In addition to this, the HPS lamps always augment the yield of cannabis, so these reimburse the cost after a harvest or two. For calculating the operating cost of light per hour for a single marijuana grow light, the grower should take the combined wattage of light and divide it by 1000 to get it in Kilowatts. Then multiply the number obtained by the sum of the KW per hour from the provided and charged by Electricity Company.
