What Every Modern Grower Needs to Know
For years, the cannabis community has been split into two camps when it comes to indoor lighting: the old-school HPS loyalists and the new-wave LED evangelists.
But which is actually better for your grow—High-Pressure Sodium or Light Emitting Diodes?
Let’s settle the debate with real data, real-world insights, and a no-nonsense look at what matters most: yield, efficiency, and quality.
💡 The Basics: What’s the Difference?
| Feature | HPS (High-Pressure Sodium) | LED (Light Emitting Diode) |
|---|---|---|
| Light Spectrum | Narrow, red/orange-heavy | Full spectrum (customizable) |
| Heat Output | High (runs hot) | Low (runs cool) |
| Energy Use | High | Low to moderate |
| Lifespan | ~10,000 hours | ~50,000 hours |
| Initial Cost | Low | Higher upfront cost |
🌿 Real Results: Yield Comparison
| Setup | Average Yield per Watt | Notes |
|---|---|---|
| 600W HPS | 0.5–0.7g/watt | High heat, frequent bulb changes |
| LED Equivalent | 1.0–1.5g/watt | Lower heat, better light penetration |
💥 LEDs outperform HPS in grams per watt, especially in controlled environments.
Result: Higher efficiency = more grams, less electricity.
🔥 Heat & Environment
HPS lights generate a LOT of heat, requiring extra ventilation and sometimes air conditioning—especially in summer or small tents.
✅ LEDs run cooler, reducing:
- Stress on plants
- Humidity swings
- Energy costs from fans and exhaust systems
💸 Energy Efficiency: The Money Talk
Let’s say you’re running a 600W HPS vs. a 480W LED for 18 hours/day in veg and 12 hours/day in flower.
Over a 3-month grow:
- HPS energy usage = ~650 kWh
- LED energy usage = ~390 kWh
- At €0.20/kWh, that’s a savings of €52+ per cycle—plus lower cooling needs.
Over time, LEDs pay for themselves.
🌈 Quality of Buds: Terps, Trichomes, and Taste
Many growers report:
- Denser buds under LED (with proper spectrum)
- Increased trichome production
- Stronger aroma and flavor profiles
Why? Full-spectrum LEDs mimic natural sunlight, helping bring out a strain’s true genetic potential—especially for terpene-rich strains like Purple Ghost Candy or Black Orchid Auto.
🧠 Final Word: Should You Switch?
If you’re growing at scale and managing heat well, HPS still works. But if you’re looking for:
- Better efficiency
- Cooler temps
- Longer lifespan
- Higher quality yields…
