How do I determine light needs, height, and duration for my plants?

Check your plant's Daily Light Integral (DLI) and use our PPFD values at different heights to calculate optimal lighting duration.

How does this light compare to red and blue spectrum lights?

Our 4000K full-spectrum light mimics natural sunlight, suitable for various plants without causing light pollution. Ceramic construction ensures durability and safety.

How energy-efficient is this grow light? Will it significantly increase my electric bill?

Our LED grow light consumes 15W, costing approximately $0.65 per month (12 hours/day) at $0.12/kWh. LEDs like ours are highly efficient, providing cost-effective lighting solutions for plant growth.

I prefer growing tropical plants. Is this light suitable for that?

Yes! Our full-spectrum light mimics natural sunlight, essential for tropical plants. With a high PPFD of 265.58 μmol/s/㎡@1ft, it promotes fast photosynthesis and robust growth, evenly illuminating plants for compact, symmetrical growth.

What's the best light for indoor plant growth?

Plants need specific light at different stages -more blue for growth, more red for flowering. Our Full Spectrum Lights meet these needs and provide optimal conditions. Adjust duration and maintain optimum height above plants for even growth.
