HPS Lighting Explained

High Pressure Sodium (HPS) lighting has been at the heart of indoor growing for decades. While LED technology has become increasingly popular, HPS still offers several advantages and remains a great option for many growers.

What Is HPS?

HPS lights produce a powerful spectrum that’s proven to grow healthy plants, but they also generate considerably more heat than modern LED fixtures. For some growers, that’s actually an advantage.

Advantages

Additional Heat

HPS fixtures naturally warm the grow room, making them ideal for colder environments where extra heating would otherwise be required.

Proven Technology

HPS has been producing excellent harvests for years and remains a trusted choice among experienced growers.

Budget Friendly

For growers working with tighter budgets, HPS can still offer fantastic results without the premium price tag of high-end LED systems.

Things To Consider

Less Efficient

HPS fixtures require more electricity to produce the same level of usable light as modern LED systems.

More Environmental Control

The additional heat means you’ll often need larger extraction fans, filters and environmental controls to keep temperatures under control.

Great In Hybrid Setups

Some growers even combine HPS with LED lighting to introduce additional warmth while benefiting from the efficiency of LEDs.

Ian’s Verdict

If you’re growing in a colder environment, working with a tighter budget, or simply prefer traditional growing methods, HPS can still be an excellent choice. The best advice? Speak to your local grow shop, explain your setup and your goals, and they’ll help you choose the right lighting for your grow.
