NorbBOTANIC® (Nutri-Orb) are specialized White-Light LED grow bulbs that provide the right spectrum for growing plants.

Plants are a lot like people and pets, the need proper nutrition to thrive. Typical LED grow lights use a combination of red and blue diodes that emit a violet-pink color that is unsuitable for most places that people work, learn, heal, shop and live. NorbBOTANIC grow bulbs are designed to provide the light-nutrition that plants need in a comfortable color for people living and working among them.

NEW NorbBOTANIC LED Grow Lights

Our line of grow lights has expanded to more than just living wall lighting. We are proud to offer grow lights in multiple shapes and sizes that provide the best spectrum for growing greens and seeds indoors.

LiveWall’s founder, Dave, is a biologist and horticulturist that wanted to discover the perfect grow light spectrum that outperformed all others. He evaluated 20+ different grow light spectra, in order to determine which spectrum provided the best growth for plants, such as house plants, herbs and vegetables. Dave says, “During the 18 month grow trial, we assessed the quality of the stems/leaves, health and trueness to color, and even flavor – compared to plants growing outdoors in direct sun. NorbBOTANIC offers the leading grow light spectrum for happy and healthy plants.”

Frequently Asked Questions about Lighting Green Walls

Is supplemental lighting required for indoor living walls?

Lighting is critical to the success of your living wall. In nearly every indoor application, supplemental lighting will be necessary to ensure the proper intensity and spectrum for plant growth. Designers should specify fixtures, bulbs, and placement to ensure that the living wall is evenly lit and receives the full spectrum of lighting required to grow healthy plants.

What light intensity is required for indoor green walls?

Light intensity is a measure of light energy hitting the plant surface and is also very important to plant health. For traditional interior lighting applications, light intensity is discussed in terms of foot-candles of light energy. While foot-candles is not the preferred measure of light intensity by horticultural scientists (who prefer a measurement in terms of “photo active radiation”), we have found that foot-candles will suffice with a proven light source, such as LiveWall’s Norb® Botanic. And, for most tropical foliage plantings 200-400 foot-candles of light energy hitting the foliage, is sufficient.

LiveWall, LLC has developed a plant selection and pairing guide for indoor plants based upon their lighting and water needs, and growth habit. This LiveWall design guide should be consulted for the correct light intensity for the type of plants that one intends to use. We have categorized the plants into lighting needs as follows:

Bright Light

Indoor location with direct light from a south or west exposure where the plants receive 2 or more hours of direct sun, but preferably not during the hottest part of the day.

Artificial Bright Light is approximately equal to a four tube florescent fixture in close proximity to the planting, in the range of 400 to 600+ foot candles, for 12 to 15 hours per day.

Medium Light

Indoor location with direct light for a couple of hours in the morning or afternoon (from east or west facing windows), or from a south facing window provided the location is several feet interior of south facing windows.

Artificial Medium Light is approximately equal to a two tube florescent fixture, 2 or 3 feet from the foliage, in the range of 100 to 400 foot candles for 12 to 15 hours per day.

Low Light

Low Light pertains to an indoor location that is not close to windows or supplemental lighting—typically a north or east exposure.

Artificial Low Light is enough to read a newspaper, in the range of 25 to 100 foot candles for 12 to 15 hours per day.

What type of lighting fixtures and bulbs are best for indoor living walls?

Light fixtures should be adjustable for direction and are typically located in front of the living wall and attached to or suspended from the ceiling. Occasionally, they are located at the bottom or sides of the LiveWall structure, to create proximity to the plants, and thereby provide sufficient light intensity across the entire wall surface. Often times, track lighting is used as it is contemporary, comes with many fixture options, and is relatively inexpensive.

In respect to the light source (bulb), the key considerations are proper light spectrum and light intensity. Plants tend to respond to blue and red wavelengths and in a proportion not available from incandescent or typical office-type LED lights.  There are, of course, LED grow lights composed of red and blue diodes—but they tend to cast a purple light which looks odd, unnatural, and unattractive.

For this reason, LiveWall LLC developed the Norb® (Nutri-Orb) Botanic, a specialized White-Light LED that provides the right spectrum for growing plants. With Norb® bulbs, the plants can be healthy and “look right under white.” 

Where on the ceiling should lighting be affixed?

While each light source may have a different beam angle and intensity, it is important to keep in mind:

  1. The distance that the planters sit from the wall.
  2. The distance that the plants may extend from the planters.  This distance will be greater with large-leaved, billowy plants.

As a rule of thumb, when using Norb® Botanic to light your indoor LiveWall, we recommend setting the track lighting fixture back 7′ from the building wall.  This should allow ample room for the vegetation and support even light distribution.

Track lighting offers flexibility

This living wall installation is lit by 12 Norb® bulbs (6 with 30 degree beam angle and 6 with 15 degree beam angle) directed at the 8’ x 8’ and 11’ x 11’ walls.

These bulbs are angled from track lighting attached to the 12 foot ceiling. This configuration provides plenty of light.

The following lights are NOT recommended for growing plants:

Halogen

Halogen lights do not have the proper spectral components for growing plants.

High Pressure Sodium

High Pressure Sodium lights are yellow in appearance. Their spectrum supports flowering but lacks the spectrum needed to support indoor foliage plants.

They may support living wall plants only when combined with a Metal Halide light.

Ordinary LEDs

LED lights that are commonly used in office or exterior lighting—typically with color temperatures of 3000K-4500K— are not suitable for plant growth.

Specify Norb Botanic when LED lighting is preferred.

How long should indoor plants be artificially lit?

Plants need a dark period to rest and prevent metabolic fatigue. Therefore, grow lights should only be run 12-15 hours maximum per day—typically from 7 AM to 8 or 9 PM (to mimic light conditions in tropical regions). The rest of the time, they should be in darkness, or near darkness.

If security lighting is required in the area of the LiveWall, it should be of very low intensity and not directed toward the plants.

Do not run Norb® bulbs (or any bulb labeled as supporting plant growth) on the green wall for more than 15 hours per day.

Fourteen hours is recommended for running lights.

We recommend running the lighting for the living walls on a dedicated outlet programmed to run for 14 hours per day.

Can I use LiveWall to grow herbs and greens indoors?

The LiveWall system does an excellent job of growing a broad array of greens, lettuce and herbs.  When those plants are grown indoors, the plants must receive enough light of the correct spectrum.

Fortunately, we have a solution for that!  We have tested and selected a lighting product with the best overall plant growth performance and value.  We developed an ingenious bracket for mounting these lights and allowing for simple plant replacement or system inspection.
