250 Watt HPS Grow Light
Once you get down below 400w, HPS lighting begins to make less and less sense. A 250 watt HPS lamp makes sense for a small 2 by 2 foot garden, but if you have anything larger, I’d use at least 400w bulbs. And even for a 2×2 space, I’d consider going 400. The extra power will only help.
What is a HPS grow lights?
Before we look at some of the best HID 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.
Nowadays, besides LEDs, you’ll encounter high-intensity discharge (HIDs) in any commercial grow lights. Hobbyist growers also have great results with HPS as well.
Known for their high light intensity and PAR output and a great pairing with Metal Halide lights, it’s no wonder that HPS will still have their place in any modern growing systems.
How To Choose The Best HPS Grow Lights?
Cost
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.
PAR
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 grow 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.
