6 Best HPS Grow Light Reviews in 2019 – Top Advice
HPS grow lights are essential for indoor vegetation. Their importance can’t be overemphasized which is why we have decided to write about them. In this article, we will be giving you some necessary information about them. Not only that, we will be reviewing some of the best HPS grow lights available.
What Are HPS Grow Lights?
HPS grow lights are also known as High-Pressure Sodium Lights. These types of light fall under the High-intensity Discharge (HID) grow system. The other type of light under the HID grow system is the MH (Metal Halide) but we won't be discussing that now.
The HPS light produces a red spectrum light which is good for budding and flowering. Also, the HPS light is energy efficient as they make use of up to 40% of the electricity that goes into it to produce light. Finally, HPS lights are known to produce a great deal of heat which is why users are advised to use cooling fans with them.
How To Choose The Best HPS Grow Lights?
We will be giving you some tips on how to choose the best HPS grow lights for you below:
Regardless of what you are buying, the cost is very important. In the case of an HPS grow light, you need to consider the price tag on the product before making a buying decision. This is because you do not want to buy products that will put a big hole in your pocket.
However, this is not to say you should go for the cheapest HPS grow light. What you need to do is to compare different products in your price range with the features they offer. With this, you will not only be getting a good HPS light but at a good price too.
PAR stands for Photosynthetically Active Radiation. Yes, radiation is a scary word but not to plants. This is because the PAR radiation helps in creating photons that produce light to help the plants grow. So, when you see an HPS light with high PAR value, go for it because it means it will help your plants grow faster. So, in conclusion, the higher the PAR value, the more photons the HPS light will produce.
You have a choice of choosing among the 150, 250, 400, 600, and 1000watt HPS grow light. The 150watt and 250watt HPS light are capable of covering 4 square feet and 9 square feet of space respectively. If you want to cover a bigger space, then you should be looking at the 400 watts and 600-watt HPS light. The 400-watt HPS bulb is capable of covering up to 16 square feet while the 600-watt bulb can cover up to 36 square feet of space. For large scale use, the 1000 watt HPS light is the ideal choice because they can cover up to 50 square feet.
Finally, note that if you use an HPS light bigger than the area you want to cover, you might end up burning your plants.
An HPS grow light needs a ballast to run and there are different types of ballasts to choose from. But, digital ballast remains the best option and this is due to many reasons. First, digital ballast is compatible with almost all types of bulbs. Not only that, they run cooler and they use less electricity. Also, it is advisable to go for dimmable ballast as they also help to protect the plants from burning.
