What is HPS grow light? 2020 Updated

HPS Grow Lights
HPS (High Pressure Sodium) Grow Lights are a specific type of HID grow light often associated with a reddish/orange-ish output. If you have ever seen a friend’s indoor grow light and noticed it had a red/orange appearance, it is likely an HPS grow light. You may have also seen HPS lights used in parking lots and street lights because they provide a lot of illumination and they’re brighter than fluorescent lighting. While HPS grow lights are also used for general lighting applications, high-quality HPS grow lights are engineered specifically to grow plants and put out even more light than standard HPS lighting.

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 orange and red lights.

What is the difference between HPS and MH lights?
The main difference between these two types of grow lights is the spectrum they produce. MH grow lights produce a blue spectrum, perfect for vegetative growth, whereas HPS grow lights emit a red spectrum, ideal for flowering or blooming. The differences in spectrum is due to the type of gas in each tube. Growers should have both types of HID lights to grow a healthy plant.

How To Grow Marijuana Outdoors: The Ultimate Guide

GROWING CANNABIS INDOORS VS OUTDOORS: DIFFERENCES Growing outdoors usually means more space to work with, plenty of sunshine, free rainwater, better ventilation, and the joy of cultivating in the elements. However, growing outdoors also comes with a set of challenges. Plants are more vulnerable to pest insects, larger predators, heat waves, and cold snaps. Growing indoors by marijunana grow tents and cannabis grow lights offers plants more shelter, and cultivators are in complete control of the growing environment. They are free to change temperature and humidity settings, and their plants are more concealed. With that said, indoor growers usually have less space at their disposal, less potential for massive yields, and have to splash money on electricity bills to run their setup like HPS grow lights .

How Much Marijuana Can I Yield by using 8×8 Grow Tent? 420 Guide

How much marijuana can you yield indoors? Lights are of the utmost importance when you’re growing indoors. Experienced growers can produce about a gram of marijuana per watt of light (1 gram = 0,035 oz). So, a 400-watt HPS grow light can potentially translate to 400 grams or 14 oz of dried, usable cannabis. Likewise, a grow tent for marijuana with 1200 watts of light can yield 1.2 kilograms or 42 oz of cannabis. Having the right equipment, adequate nutrient solutions, beneficial air quality, and other valuable factors is important for producing the highest yields possible. Making sure the plants have space to grow is also key. Maximum indoor yield Get the right light but don’t forget you’ll also need the right nutrients, the right equipment, good air quality, a good room for the plants to grow in, and plenty of time for the attention you’ll need to give it if you want the highest possible yield.
