![]() ![]() LED gives you the option to switch up your scheme in different stages of development. Green, red, and blue spectrums affect root formation, growth, and flowering. Grow lamps combine multiple types to create a scheme that mimics natural light and fits budding cannabis. In isolation, each diode produces a single narrow color range. ![]() They’re worthy contenders in the LED vs HPS discussion because of the color spectrum they produce. These lamps consist of multiple individual diodes in a case with a heat reservoir and built-in fans. Light-emitting diodes, or LEDs for short, have a much more straightforward mechanism. If possible, vent the exhaust near the top of the tent or room – the warm air will rise naturally and pull cooler, fresh air back into the space. Keep the run as straight as possible to ensure a smooth air flow. The exhaust run should be as short as possible because the farther the air has to travel, the more inefficient the system will become. Install An Exhaust SystemĪn exhaust system is the key to regulating the temperature inside the grow tent, keeping it within the optimal range. It is important to check the height of your plants regularly, lights must never be placed too close or too far from the plants.Ĭheck out our report on “ grow lights distance chart” for more details. Increases in the plant-lamp distance means decreases in intensity of coverage, but it does mean the lamps cover a larger area. Putting enough gap between the two will prevent the heat from overwhelming the plants. It has to be hung over the vegetation at a distance that is relative to its corresponding wattage. You will need to maintain a large gap between the plant and the light source. HPS grow lamps give off a serious amount of heat. Work towards at least 50 watts per square foot, 60 to 75 is acceptable. The appropriate wattage is dependent on the size of the grow space. They are widely regarded as the best kind out there because they maximize light output while simultaneously consuming less power. A digital ballast uses computer chips to draw sufficient electricity to power the lights. Remote ballasts have a long cord allowing them to be placed outside the grow room. It’s best to opt for either a remote or digital ballast if your budget allows. Ballasts also produce a significant amount of heat. Without it, the lamps will overheat and burn out. This regulates the current and provides the required voltage to start the lamp. Vent holes help diffuse the excessive heat emitted by the lamps. Make sure they have at least a 6-inch vent hole on both ends to ensure maximum airflow and cooling. They are glass-bottomed and can be equipped with exhaust fans. There are many models available, the best ones being air-cooled hoods that fully enclose the bulb. With an omnidirectional HPS bulb, a hood must be used to focus the light on the plants. Choose The Right AccessoriesĬhoosing the best components is key to getting the most from your HPS grow lights. To create optimal growing conditions, you’ll need to learn a little about wattage, plant-lamp distance and temperature regulation. Growing cannabis plants using HPS lights requires setting up the different components that make up the lighting system. LED debate, but if you’re interested in the MH or HPS decision, you can check out our report on that matter. ![]() MH and HPS grow lights, commonly used high-intensity discharge systems, are still a go-to for old-school growers. They’re quite big, too, at least in the LED vs HPS comparison, with a metal hood and an exhaust fan on one side. These systems are pretty powerful, producing more than 140 lumens per Watt, which is a lot of light for your cannabis to enjoy. The mediation of xenon and mercury often seen in these lamps results in a whiter light, making it seem more natural. Sodium, in particular, emanates a yellow-orange shade. Heated sodium vapor produces light when the pressure rises high enough.Mercury heats to raise the pressure and the voltage.Electrodes receive voltage, which strikes the arc tube by ionizing the xenon.The section called an arc tube contains sodium, as well as some mercury and xenon.They produce light through an interaction between electrodes and gas, most often metal halide or sodium.Īs an abbreviation, HPS stands for ‘high-pressure sodium.’ Here’s how the system works: HPS is a subtype of high-intensity discharge lamps (HIDs), popular for their high efficiency and long shelf-life.
