Lighting Strategies That Maximize Yield: From Veg to Late Flower

(A Cannabis Cultivation Lighting SOP Guide with Real-World Application)

Whether you're running high-pressure sodium, LEDs, or a hybrid, lighting isn't just about lumens anymore—it's about timing, spectrum, intensity, and how they all sync with your Cultivation Standard Operating Procedures.

This week, Evergreen Growers LLC. dives into lighting protocols across the Seed-To-Harvest SOP Vault, including insights from our NFT SOPs that make compliance, optimization, and scalability easier than ever.

🔆 1. Know Your Lighting PPFD Benchmarks

If you're not measuring Photosynthetic Photon Flux Density (PPFD), you're guessing. And guessing leads to inconsistent yields.

Growth Stage	Ideal PPFD (µmol/m²/s)	Light Cycle
Clone/Seedling	100–300	18/6 or 24/0
Vegetative	400–600	18/6
Flower (Weeks 1–4)	700–900	12/12
Flower (Weeks 5–8+)	900–1100	12/12

NFT Spotlight: Our “Flower Light Requirements” NFT walks through spectrum staging, dimming schedules, and sunrise/sunset simulations. It's pulled directly from our Cannabis Cultivation SOP Templates and minted to verify compliance and reduce training errors.

🌈 2. Spectrum Strategy by Stage

Blue-heavy spectrums promote compact vegging plants. But what most cultivators overlook is far-red integration during flower, which stimulates phytochrome responses and increases resin production.

Evergreen Growers LLC. Pro Tip: Install tunable LEDs or supplemental red/far-red strips for peak bloom results. Run your last 15 minutes of lights-on in pure far-red to trigger faster transitions.

⚠️ 3. Light Stress Is Real

Light too intense? Leaves taco. Too weak? Plants stretch. Here's a simple SOP from our Cannabis Operation Management files:

• Daily Light Integral (DLI) Calculator: Use your PPFD and photoperiod to calculate DLI

• Monitor canopy temperature with IR guns (not room temp!)

• Adjust lights weekly as plants grow to maintain distance and avoid hotspots

💬 Engagement Corner: Share Your Light Setup

What lights are you using, and how are you optimizing for each growth stage?

🌱 Are you team HPS, LED, or hybrid?📏 What’s your average DLI target during flower?🔄 Do you use automated light dimming or spectrum shifts?
