Growing plants in closed and fully controlled environments, under artificial lighting is method of growing popularity. There is also increasing competition to have results at a low cost and as fast as possible, thus the lighting system plays a crucial role.
Below you will find a quick guide how to build the most efficient lighting system.
1) Research, research
Understand what spectrum and intensity of light your plants need.
2) Choose the right PPFD and light color for your plants
With the latest technology achievements, special or full spectrum white light LEDs are the most efficient and cost effective light sources for plant growth. With 3000K white color temperature you will have more pleasant looking plants while with 5000K you obtain faster growth.
With our Nichia 757 Rsp0a LEDs with white light for special spectrum for plant growth or full spectrum Nichia Optisolis CRI98 LEDs your plants will grow up to 50% more than conventional light, including standard white LEDs, a combination of red and blue LEDs or a fluorescent tube, for lower energy consumption.
The PPF and PPF/Watt values of our LinearZ modules are in the table below. You will also find the PPFD per square meter from a distance of 30 cm between the LEDs and the plant leaves:
Examples of recommended PPFD (PPF per square meter) for some common plants grown indoor:
To light the plants in the table above you can use the below recommended data, for each square meter of soil.
At a distance of 30 cm two LinearZ LED modules 3000K will have 354 PPFD while at 56 cm only 100 PPFD. We recommend 30 cm as the optimum distance between the leaves and the LED modules.
3) Minimize energy cost. Efficacy: PPF/Watt
The LED system should deliver high PPF for minimum power consumption (PPF), so your operating costs are very low. For example, our LinearZ Nichia Horticulture Rsp0a LED strip at 5000K has 1.82 PPF/Watt, one of the highest on the market.
4) Take care about color stability
The LED system should have a minimum color shift over its lifetime of operation otherwise the effective of growing plants will be severely affected.
As a general rule, long lifetime LEDs, such as those manufactured by Nichia, Osram or Cree has excellent color stability. Our Nichia LED modules have very good color stability for a minimum operation period of 60.000 hours.
5) All LEDs should have 3000K or 5000K
White LEDs, as with all manufactured products, have material and process variations that yield products with corresponding variation in the shade of white light emitted. For example Nichia warm white LEDs just out of the production line can have a color temperature between 2580K and 4260K. If they would be directly integrated into strips or luminaries for plat growth the results will be very poor.
To prevent the issue above LEDs must be sorted and grouped in batches known as "Chromaticity Bins". Thus to have have all the LEDs in the strip with 3000K or 5000K a 3-step MacAdam Ellipse sorting is a must.
6) Modules must be easy to install or replace
Horticulture makes intensive use of the lighting system, with typical 12-16 hours daily run time. For this reason the modules or strips should be easily replaceable. The Zhaga shape and connection standard is recommended, as it means LED strips can easily be installed or replaced.
Our LinearZ LEDs are available in easy to install plug & play modules with Zhaga Standard. LinearZ 52 complies with Zhaga Book 7 L56W2 and LinearZ 26 with Book 7 L28W2.
LinearZ modules use a Plug & Play power system that allows wires to connect without using a soldering gun and are available in the constant current version for the highest energy efficiency.
