Have you seen the light? Do you know what’s on the other side?
Well, we haven’t but love talking about high pressure sodium (HPS) vs light emitting diodes (LED)
Let’s break this down. HPS has a huge following, it was the first widely accepted lighting option for the indoor grow space. The “old timers”, wups! I meant “more experienced growers” will tell you LEDs just don’t have the power of HPS and cannot produce the same outcomes. That is not true. According to Perdue University you can, in-fact, achieve the same outcomes with the more efficient, environmentally friendly LED lights.
Looking at the details: HPS lighting produces a great deal of energy and are relatively inexpensive. You also have countless models to choose from. On the flip side, HPS lights give off a huge amount of heat requiring you to counter cool with your HVAC system. HPS lights also have a much shorter life span than LEDs.
In summary, HPS lights are proven and less expensive upfront… but use more energy and burn out faster.
On the other hand, LED lights can more efficiently produce energy that offers greater lighting spectrums for your plants, they also last on average 50,000 luminous hours or more than HPS lights. LEDs are often also offered with government provided rebates! So, while LEDs are initially more expensive upfront, you may spend less than an HPS set up. The savings do not stop there. Because LEDs don’t generate the same heat, you won’t have to run your HVAC to counter the additional heat load.
In summary, LED lights are the future for many crops. LEDs offer a wider spectrum of light, use less energy and last longer. Except for very cold environments that will benefit from the HPS heat production, soon LEDs will be used in most ever single grow.
