Indoor Plant Lights: Growth vs. Decorative—Choose the Right Type

Not all plant lights grow plants. Understanding the two categories saves money and frustration.

Grow Lights: For Photosynthesis

These deliver photosynthetically active radiation (PAR)—400–700nm spectrum plants use. Types:

• LED full-spectrum—efficient, cool, tunable, long-lived. Best all-around.
• T5/T8 fluorescent—affordable, good for seedlings/leafy greens.
• HID (MH/HPS)—intense, hot, high electricity. Overkill for most homes.

Match intensity to plants: seedlings need 12–16 hrs/day at 2–4 inches; mature tropicals 12–14 hrs at 12–24 inches. Use timers.

Decorative Lights: For Aesthetics

Spotlights, fairy lights, or LED stakes highlight plant form at night. They emit negligible PAR—useless for growth. Use for drama, not survival.

Value Shopping

Compare PAR output (µmol/m²/s), spectrum charts, warranty, and reviews—not just watts or price. Reputable brands publish specs. A $60 quality LED outperforms a $30 generic for years.

Define your goal. Buy accordingly.
