HPS grow lights

Light Distances for Growing Cannabis with HID Lighting HID grow lights like Metal Halide and HPS (High Pressure Sodium) are the most widely-used and debatably the highest-yielding grow lights available for growing cannabis. Metal Halide lights are well-suited to the vegetative stage and tend to encourage plants to grow short and squat though they are less electrically efficient than HPS. HPS grow lights are suitable for both the vegetative and flowering stage of cannabis growth and the light they give off encourages plants to quickly grow tall and produce big buds. Despite these differences, MH and HPS bulbs need to be kept about the same distance away from your plants. The proper distance actually depends on the size/wattage of your lamp. In addition to the wattage, it’s important to realize that older bulbs stop giving off as much light over time, so new MH/HPS bulbs generally need to be kept further away and older bulbs should be kept closer than the normal recommendations. ...

What is a HPS grow lights? Before we look at some of the best HPS grow lights in the market, it is good to understand what they are first. HPS stands for high-pressure sodium. HPS light comes in the form of a narrow arc tube held by a wire frame. HPS light contains xenon gas, high-pressure solid sodium and mercury. How HPS light works HPS light works by using ballast, which creates a pulse that stirs the gas in the bulbs or lamps. The ballast first ignites the xenon gas, which in turn generates a flow of electrons. The electrons heat up the arc producing a pale blue light. After this, the arc vapors mercury into gas generating a deeper blue color. Finally, the sodium gas vapors turn the arc into a yellow color spectrum. These are all the colours that provide lighting effects that influence the growth of the crops. All the colours have different wavelengths depending on the gases inside them. Majority of the HPS bulbs are ideal for the FLOWERING phases of the crops because of their ora...

Benefits of HPS Grow Lights When choosing a high pressure sodium grow light, use the wattage to determine how large of a grow area the lamp can cover. 150-Watt HPS grow lights are for very small spaces around 4 square feet. 150W HPS grow lights can be used to grow lettuce, herbs, and other small plants. 250-Watt HPS grow lights can cover around 9 square feet of space, making them a good choice for small indoor gardens. 400-Watt HPS grow lights are the most commonly used HPS grow bulb , covering around 16 square feet and capable of producing high yields. 600 Watt HPS grow lights are the most efficient HPS grow lamp. 600W HPS grow lights produce more light output per Watt used than other wattages and cover around 36 square feet. 1000-Watt HPS grow lights are the most powerful and cover a wider area of around 49 square feet. High pressure sodium grow lights generate heat, so higher wattages should be mounted farther away from your plants. Depending on what plants you are growing, HPS gro...
