In horticulture terms, this traditionally refers to the ratio between blue and red light. Often expressed in terms such as 6:1, or 10:1 (i.e. red:blue)
The GROW3 system is capable of more than one color ratio for each light, as each light is customizable to your needs with many having the ability to adjust from 1:1 to 10:1 ratios and everything in between.
- The SmarTune software comes with several pre-programmed lighting recipes for various types of common plants. You can use those, or use those as a basis to create your own unique color ratio for your plant variety.
LED Smart would be happy to assist with suggested design for your specific application.
Most of the GROW3 products, would only require 1 light for each 4×8 shelf, however, this also depends on the mounting height.
LED Smart would be happy to assist with suggested design height for your specific application.
The suggested µmol depends on the desired PPF and DLI for plant growth stage, plus several other factors, such as, greenhouse structure and plant type. LED Smart would be happy to assist with suggested design for your specific application by designing a lighting layout plan unique to you.

Used typically for commercial or residential lighting systems, the measure of a light’s color rendering index (CRI) is a measure of the ability of a light source to reveal the colors of various objects faithfully in comparison with an ideal light source (i.e. the sun). This value is NOT important to how a plant responds or photosynthesizes.
Where CRI is important is how well you can tell the true color of something, for example a leaf that might be chlorotic (lacking green). When you have a high CRI it is easier to detect color variations that might be indicating poor plant health. GROW3 with white LEDs has a typical CRI of 85 (out of 100). For comparison, HPS has a CRI of only 25.
- There are many rebate programs throughout North America. Each electrical provider had different project application requirements. To ensure that your project could qualify for a potential rebate please contact our sales representative for assistance. They will let you know if there are any potential rebate options available for your area.
The GROW3 system is a culmination of advanced power and control technology, high-quality top-tier LEDs, and high-grade housing materials. These critical features reduce the total cost of ownership and produce a product with long in-service life.
The system can adjust color, dim, and program schedules for the most efficient power usage and shortened growing cycles. Designed, produced and serviced from Canada, the local production gives you, the user, confidence that the customer service will be fast and reliable. All this means that your overall ownership cost is reduced over the product’s life.
LED Smart’s engineers considered other horticulture lighting systems when designing this product line and applied our decades of experience to a new and innovative grow light system. As a result, GROW3 fills in a unique gap that was missing in the grow light industry.
Utilizing the features that our clients in the transportation and military industries have come to rely on for high-quality, long-lasting, durable LED lighting systems. Within the GROW3 product line, the design features such as the military-grade aluminum body, the high impact resistant ultra-clear lens, and the use of top-tier LEDs within the system are some of the unique features.
Compared to other LED grow lights on the market, the GROW3 can control each part of the spectrum of the light available in each type, allowing the user to generate their own color ratios. In addition, the ability to dim the GROW3 system without losing the high PPE is also a unique advantage; the user can set the color AND the light intensity and still achieve their required PPFD and DLI.
The ability to control the GROW3 fixtures through various control methods so that each user can customize their set-up without complication means that the user can add to existing building controls too. In addition, the inclusion of the SmarTune technology in each fixture allows the user to set up the system in a quick and precise manner.
LED Smart also offers the control systems and APP at no charge to the users.

- This is not recommended, but it is possible. Depending on how the lights are powered, the light may be turned on-or-off using the main power switch, the same as any other type of light fixture.
A Bluetooth® mesh network is self generating; you do not need to do anything to create a ‘mesh’ other than turning on the light fixture. Each node within the mesh can connect up to 800 nodes total.
- Hybrid mesh is a combined method of communication utilizing Bluetooth®, PLC and Wi-Fi. This hybrid method takes advantage of the best of each method to deliver uninterrupted control signals to the GROW3 system.
- PLC is Power Line Control, a new method of control signal delivery. This method uses the existing power line, provided with each light, to send a momentary signal for controls. This new method allows the integration of new technology into existing infrastructure without major controls or building upgrades. PLC also reduces the overall weight of control signal systems, as no additional wiring is required.
The SmarTune controls come with each GROW3 fixture. These controls allow you to program the color ratios, schedules, zones, and other features.
You may be able to order your GROW3 products without the SmarTune controls. However, these cannot be added to the system at a later date if you change your mind
- Yes, the SmarTune has pre-programmed color ratios for various growth stages. Such as seedling, rooting, greens, bud and flower stages. These are basic pre-programmed settings, which you can use as a starting point to make the color ratio that works best for your plant cycles and growth stage.
There is a feature in the current Android version SmarTune™ APP to put the lamps into different locations, groups and zones. Inside this feature, a user can visually view the icon representation of each light.
After creating the locations, groups and zones, the user can operate a group of lights the same as a single light.
PAR: The type of light that a plant can ‘see’ is far greater. How grow lights efficacy and light output is measured is different from traditional light systems. Plant spectrum is often referred to as PAR (Photosynthetically Active Radiation). The type of light that drives the majority of photosynthesis. The visible light from 400-700nm.
PPF: The method of measurement for grow lights is different than regular lights. This number is expressed as PPF (Photosynthetic Photon Flux) or the measurement of the total photons of PAR that is emitted from the light fixture. This is expressed as µmol/s (micromoles per second). This number is the key to measure the overall quality of a grow light. This number helps to compare the amount of photons for photosynthesis of one grow light to another.
PPFD: Photosynthetic Photon Flux Density – how many photon densities are delivered. Typically measured in µmol per square meter, per second.
PPE: PPE (Photosynthetic Photon Efficacy). The measurement of the efficiency of the fixture to convert electrical energy (watts) into light (PPF). This measurement is calculated by the µmol/s divided by the input power (watts). One watt equals one joule per second (J/s). The measurement is expressed as µmol/J That all sounds complicated. However, this is an effective method to compare one type of grow light to another. However, it should not be the sole factor of consideration.
DLI: Daily Light Integral is the measurement of the PPFD delivered to an area of 1-meter squared (1M2) over a 24-hour period. Measured within the standard PAR (400-700nm) range only.
The GROW3 products come with a variety of options. GROW3 products are available from power sizes 40W to 320W. Within each size, there is a light color solution for your application. All products operate with input power from 100-277VAC; for special voltages, don’t hesitate to get in touch with our sales team for assistance.
- Each GROW3 is provided with a 14 gauge, 3-conductor, waterproof connector, so that you can connect any length of cable desired to the light.
- Ask your sales representative for more information.
The connector to the light fixture is a branded waterproof horticulture connector.
- Please contact our sales team to confirm if the product is certified for use in your country.
- GROW3 has many options, each designed for different crop types. To help you find the best GROW3 for your growing conditions, we need to answer a few questions to suggest the right GROW3 for your application:
· What crop are you growing? (e.g. tomatoes, lettuce, roses)
· What stage of growth for this area? (e.g. seedling, rooting, clone, leaf, flowering)
· What is the mounting height of the light to the crop canopy? (e.g. 18” ~ 14’0”)
· What is the size of the growing area? (e.g. 5,000ft2)
With this information, our team can assist you in finding the right solution for your growing area.
- Depending on the series you are using and the size of the power breaker, the maximum amount is 8-10 lights in one circuit. Some higher-powered GROW3 systems may be limited to only 6 per circuit (e.g. 6 x 320W on 20A 120V breaker).
- The Grow 3 fixtures are designed to be passively cooled using natural convection without needing a fan, despite a higher ambient temperature.
This passive cooling design ensures that the power is used towards light output and growing the plants instead of cooling the lighting system.
- It may feel warm depending on the air temperature and air velocity around the fixture. This is normal, as the fixture housing is designed to draw heat away from the LEDs and drivers. However, as these are high-power lighting systems, we do not recommend handling them while in operation.
Unlike traditional lights, the watts and light output are not the measurements that are solely used to consider the best illumination for the plants. While an average watt per square meter may be able to be calculated, the best method is PPFD, or µmol/m2/second, and DLI (mol/ m2/day).
Each plant type requires a different level and kind of light at each growth stage. Too much light and you could ‘burn’ your plant, and too low, the plant will not grow to optimal performance.
- Yes, PPFD maps are available for our products. Please email us with the specific light fixture that you are looking for.

- All lighting systems produce heat, but our systems have very little heat. The heat from a light fixture is from poorly designed power supplies and ballasts. Fluorescent and HID light systems traditionally rely on heat transfer by radiation, which generates a great deal of heat to the surrounding environment. Most of a poorly designed product’s efficacy is lost through heat from the lamp or the ballast. This poor design feature is compounded by the aluminum reflectors commonly used in these systems, which can substantially impact the temperature at the canopy level.
LED Smart’s GROW3 is designed to conduct the heat away from the fixture by conduction and convection. This is why the sides and backs of the GROW3 fixture body may feel warm. However, since convection is carrying the heat away from the fixture from the top of the fixture, your canopy temperature will be minimally impacted in comparison with fluorescent or HID lighting systems.
- A customized lighting fixture layout plan will assist you in determining the best layout for your location and demonstrate to you the potential lighting volume of your space.
Free of charge, our team will gladly assist you in designing your lighting plan. With a little input from you, our specialists can create the best lighting options for your growing needs.
Each lighting plan is unique to the specific location. Your customized lighting plan to correctly calculate the number of fixtures, suggested mounting height unique to your environment.

Power savings is based on the number of hours of usage and the light wattage, or power consumption. On average the initial installation from HPS to LED easily saves 40%. Utilizing the control features of the GROW3 system, such as dimming, you could save an additional 20% or even more.
Example, if you are currently using a 1000W HPS light system, installation of the Grow RE 320W system could initially save you 65%
- GROW3 systems should be installed as per the National Electrical Code. In most areas, this will require installation by a certified electrician. However, it is possible to have a direct plug and play installation, if powered through the provided NEMA 5-15 connector direct to 120VAC, for some installations.
- The suggested mounting height depends on several factors, such as, greenhouse structure, plant type, desired µmol for plant growth stage, and the series of GROW3 light used. LED Smart would be happy to assist with suggested design height for your specific application. The GROW3 systems can be installed from 17-inches up to 14-feet. growing area.
- The beauty of the GROW3 technology is that you can simply change the light intensity, in this case you may not have to change the height. However, the GROW3 installed by the provided hanging wire and quite easy to change the height at any point in the growth cycle. Each GROW3 system could also attach to any commercial greenhouse height adjustment system as well.
The GROW3 light is rated IP66 for water and dust ingress, meaning that there should be no water or dust inside your light. However, we understand that cleaning the outside of the fixtures may be desired from time to time.
It is best to consult your instruction and care portion of the manual. Never use abrasive or acidic cleaning solutions or materials on any part of the light fixture. Soft and gentle cleaning so as not to scratch the lens or the body. As it is IP66 rated, with the power OFF, the fixtures could be cleaned with a gentle spray of water. Allow to completely dry before operating.
- It may feel warm depending on the air temperature and air velocity around the fixture. This is normal, as the fixture housing is designed to draw heat away from the LEDs and drivers. However, as these are high-power lighting systems, we do not recommend handling them while in operation.
The GROW3 system is designed to operate with various input voltages. These include 120VAC, 208VAC, 240VAC, 277VAC, and 347VAC upon special order.
