Is 24 Hours of Continuous Light Too Much for Plants? 🌱💡

More light doesn’t always mean more growth.
Running *24 hours of continuous light* sounds like a shortcut — but in most cases, it actually *holds plants back* instead of pushing them forward.

Plants evolved with **day–night cycles**, and those dark periods aren’t wasted time — they’re when critical biological processes happen. Here’s why nonstop light can become a problem 👇

🌗 1. Plants Need Darkness to Reset
During the dark cycle, plants shift from photosynthesis to **respiration**. This is when sugars are redistributed, cell repair occurs, and growth hormones regulate development. Without darkness, metabolism can fall out of sync.

🧬 2. Photoinhibition & Stress
Continuous light can overload the photosynthetic machinery, leading to *photoinhibition* — where chlorophyll becomes less efficient. Symptoms include slower growth, leaf stress, and reduced vigor over time.

🌱 3. Root Growth Suffers
Roots rely on nighttime respiration. Without a dark period, root expansion and nutrient uptake efficiency can decline, even if top growth looks acceptable early on.

⚡ 4. DLI Matters More Than Hours
What truly drives growth is *Daily Light Integral (DLI)* — not total hours of exposure.
You’ll get better results hitting your target DLI over *16–18 hours* than stretching low-intensity light across 24.

🧠 The Sweet Spot
For most plants, *16–18 hours of light* in veg delivers the best balance of energy input and biological recovery — maximizing growth while minimizing stress.

Plants don’t need nonstop light — they need **balanced light cycles**.
Give them time to rest, reset, and build.
