The Common Grow Lights For Indoor Cannabis Growing
Every cannabis grower knows how important good lights is in achieving a successful harvest of marijuana. In addition to nutrition and water, it is also one of the most critical factors to ensure healthy growth and high yield.
Although natural sunlight is usually the best condition for marijuana cultivation, many growers prefer to grow indoors for a variety of reasons. Including grow lights, so that growers can better control the vegetative period and flowering period of cannabis.
Today, you can find many different types of indoor cultivation grow lights in the market. But not all grow lights are equal; In fact, there are great differences in efficiency and cost. Below is the common grow light in the market;
1-HID grow lights for indoor plants
HID ( High intensity discharge ) lamp has always been the preferred light source for every indoor grower and indoor cannabis growers (from beginners to professional growers). There are two main types of HID lamps: MH (metal halide)grow lamp and HPS (high pressure sodium) grow lamp. The difference between the two is that MH lamps produce a “colder” blue light, while HPS lamps are usually red. This makes MH Lamp more suitable for vegetative period and HPS grow light more suitable for flowering.
Very high heat requires additional equipment to operate, including electronic ballasts and reflectors, thus increasing costs. Very short lifespan, so you have to replace them regularly (usually within 3 to 6 months). In addition, they are very power consuming and may significantly increase the electricity bill. But it with good yield and good for flowering stage.
2-CMH grow light bulbs
CMH (ceramic metal halide ) grow lamp, the most common is 315w CMH bulb, but for standard MH or metal halide lamp, the upgrade cost is quite high. CMH grow light with less heat than HPS. But cost is higher.
4-LED
LED (light-emitting diode ) grow light is a new technology light source for indoor cannabis growing.
The efficiency of LED grow light is very high, and their power consumption can be reduced by up to 60% compared with the same HID, because they can produce pure light instead of wasting electricity on heat. The full spectrum LED grow light can provide suitable light for plant growth and flowering stages. the cost is higher than HPS. But LED grow light bar is easy to install. Low heat, and high efficiency .
