Artificial Light for Interior Plantscapes: A Complete Guide

Interior plantscapes bring nature indoors, making spaces more lively, refreshing, and biophilic. However, most indoor areas lack sufficient sunlight for plants to thrive. To maintain healthy growth and beautiful greenery, artificial grow lights are essential.

This guide explains the key factors to consider before choosing artificial lights, the best options available, and how to balance plant health with interior aesthetics.

Key Factors to Consider Before Choosing Artificial Light

When designing lighting for interior plantscapes, these points are crucial:

1. Growing Area (Length × Width)

• Larger areas require more lights or higher wattage fixtures for uniform coverage.

2. Height from Roof

• The distance between lights and plants determines intensity.

• Higher ceilings need stronger fixtures or focused beams.

3. Roof Type

• Transparent or Glass Roof – Partial sunlight reduces artificial light needs.

• Opaque Roof – Requires complete artificial lighting.

• True Ceiling vs. False Ceiling – Important for fixture selection:

            • True ceiling → Surface-mounted fixtures are ideal.

            • False ceiling → Concealed fixtures look elegant and blend with interiors.

4. Growing Structure Type

• Green walls → Require vertical lighting.

• Indoor gardens → Need top-down uniform coverage.

• Paludariums/Terrariums → Compact, moisture-resistant fixtures.

5. Plant Types

• Shade-loving plants need softer light.

• Tropical and large plants require higher intensity.

6. Area Location

• Indoor → Relies fully on artificial lighting.

• Semi-indoor → Artificial lights act as supplements.

Best Artificial Light Option

LED Grow Lights

LED grow lights are the most effective choice compared to fluorescent or halogen lights.

Why LEDs?

🌱 High energy efficiency

🌱 Long lifespan with low maintenance

🌱 Customizable light spectrum for plants

🌱 Slim and stylish fixture design that complements interiors

Fixture Design & Light Output

• Fixture Types – Should match the area’s interior. Slim, modern designs or concealed options work best in commercial and residential spaces.

• Lighting Output Color – Traditional grow lights often combine red and blue LEDs, making the output look pinkish. This is not suitable for interiors as it disturbs the natural plant view and reduces comfort due to low CRI value.

👉 At Nexsel, we developed special spectra that look like warm white or cool white, offering:

• A broad spectrum similar to sunlight

• CRI value above 80 for natural plant appearance

• Comfortable lighting for human visual experience

Light Intensity & Plant Health

Light intensity depends on:

1. Wattage of the light

2. Distance from plants

For large plants, higher intensity is required. Proper design is critical as it affects:

• Plant growth and longevity

• Project cost

• Energy bills

• Lux level in interiors

👉 This is where a grow light consultant plays a key role in balancing cost, efficiency, and plant needs.

Light Automation & Photoperiod

• Timers – Ensure automatic ON/OFF scheduling.

• Photoperiod – Plants generally need 8–10 hours of light and 6–8 hours of darkness daily.

• Dimming Options – Useful in areas where full darkness is not possible.

• Advanced Simulation – Modern systems can mimic sunrise and sunset by gradually adjusting intensity, improving plant growth cycles.

Applications of Artificial Light in Interior Plantscapes

Artificial lighting enhances a wide range of interior projects:

• Corporate Offices – Desk plants, green walls, lobby installations

• Hotels & Restaurants – Indoor gardens and decorative plants

• Homes – Living rooms, balconies, kitchen gardens

• Wellness Spaces – Hospitals, spas, schools for biophilic design

• Airports – Plant installations across terminals and lounges

Conclusion :

Artificial lighting is not just a substitute for sunlight—it is a core element of interior plant design. By considering growing area, ceiling height, roof type, plant species, and automation, you can achieve vibrant, healthy, and energy-efficient plantscapes.

👉 For the best results, always consult a professional grow light expert to design the right spectrum, fixture type, and intensity for your project.
