🌞 Nova Sun Series – Full-Spectrum LED Grow Lights (2026 Model)
The First & Only Sunlike CMH Spectrum
Proven Science. Bigger Yields. Higher Quality.

Introducing the Nova Sun Series by Mammoth Lighting—our most advanced line of full-spectrum LED grow lights for professional cultivators, research institutions, and high-performance home growers. Inspired by sunlight and backed by peer-reviewed science, Nova Sun is the only LED grow light series engineered to replicate a true Sunlike CMH-style spectrum while offering optional independent channel control (on select models) for White, Far Red, and UV.

🧬 Why Spectrum Matters More Than Intensity
Decades of academic research confirm: Light quality = plant quality.

🚫 Outdated red/blue or “blurple” spectrums limit genetic expression.  Many manufacturers are going back to the heavy red/blue spectrum to push efficacy numbers higher (good for marketing) ...but plant quality suffers.  

✅ Full-spectrum light mimicking natural sunlight enhances flower quality, cannabinoid levels, and terpene production

🔬 Peer-Reviewed Research Confirms:
• White Light improves cannabinoid synthesis (Magagnini et al., 2018)
• Green Light enhances penetration and morphology (Kim et al., 2005; Johkan et al., 2012)
• Far Red (730nm) boosts flower size and biomass (Zhen & Bugbee, 2020; Craig et al., 2023)
• Teal Blue (470–500nm) regulates plant structure and circadian rhythm (Lin et al., 2022)
• UV-A/B increases terpene, resin, and flavonoid levels (Ries et al., 2000; Magagnini et al., 2018; Lyu et al., 2024)

🧪 Why UV = Oil Boost, Terp Boost & Chemical-Free IPM
UV exposure triggers the plant’s defense system, increasing trichome and oil output while activating natural pest resistance.

Supported by Research:
• Ries et al., 2000 – UVB increases phenolic compounds
• Magagnini et al., 2018 – UV raises terpene content
• Lyu et al., 2024 – UVB linked to trichome density & pest suppression
• Jenkins, 2009 (Annual Review of Plant Biology) – UVB activates secondary metabolite pathways

🙋 FAQ Highlights

Q: What’s the best grow light spectrum for hemp?
A: One that mimics full sunlight—balanced red, blue, green, far-red, and UV. Nova Sun checks every box.

Q: Does spectrum matter more than PPFD?
A: Yes. Oversaturating plants with the wrong spectrum (like red/blue-heavy lighting) limits phytochemical expression. A full spectrum unlocks the plant’s genetic potential.

Q: Why does green light matter in a grow light?
A: Green penetrates deeper into dense canopies, improving lower-canopy photosynthesis, morphology, and overall efficiency (Kim et al., 2005).

Q: Do I need spectrum tuning?
A: If you’re running high-value genetics, pheno hunting, or dialing in commercial output—yes. If you want simple, proven performance, fixed spectrum models still deliver strong results.

Q: What’s the difference between the 8-bar and 10-bar systems?
A: It comes down to how you want to tune spectrum.

• 10-Bar: More advanced UV + far-red focused tuning system. Designed for deeper spectrum control with dedicated UV and far-red channels plus full-spectrum control.
• 8-Bar 950W: Traditional spectrum tuning setup using warm white, cool white, and far-red. A proven, straightforward approach. UV can be added via the upgrade kit for expanded control.

👉 Simple breakdown:

• 8-bar = traditional spectrum tuning
• 10-bar = expanded UV + far-red tuning control

Q: How is spectrum controlled?
A: Option 1 controller uses low-voltage RJ45 connections for clean, reliable channel control across the system.

Q: Why include UV in a grow light?
A: UV mimics natural environmental stress, helping increase resin, terpene production, and plant defense responses. It’s also useful as part of an integrated pest management strategy.

Q: Will this work for veg and flower?
A: Yes. All models are full-cycle optimized. Spectrum tuning systems simply give you more control over how you shape each stage.

Q: Is far-red necessary?
A: It’s part of nature. Far-red can influence canopy structure and plant signaling - YES
