Elevate Your Plant Growth The FGI Far Red LED Grow Light is a top-tier solution designed to significantly enhance plant growth by delivering 730nm far red energy, which is crucial for optimal photosynthesis. Unlike cheaper 660nm red LEDs, which fail to produce this specific wavelength, the FGI light effectively stimulates growth processes that are otherwise neglected. Its robust, commercial-grade construction guarantees exceptional durability and consistent performance, making it the 730nm choice for both amateur and professional growers seeking to maximize their yields and improve plant health. Scientific Benefits Far-red light (700-760nm) is crucial for optimal plant growth, enhancing photosynthesis and increasing plant size. Studies, such as those from the University of Texas, show that “far-red light boosts overall plant mass and terpene profiles. It improves light absorption, influences leaf angle, and promotes higher yields.”  Read the study here. Far Red light is believed to create a competitive response in plants, pushing desirable terpene production and assisting in the formation of trichomes.   The Emerson Effect Using far-red light just before nighttime increases photosynthesis, cell division, and growth. Implementing a 10-15 minute far-red light cycle after full spectrum lights are off can optimize your growing environment. Recommended Use Ideal for 4x4 grow spaces, this light is easy to install with included hardware, ensuring full coverage and enhanced PPFD delivery. Controls With an low Amp draw at .3 amps, we recommend these units are operated on standard 110V receptacles. One dedicated 15 amp circuit can safely operate more than 30 units. Standard service outlets for fans can easily be used to operate as many units as needed. Standard wall timers can serve as on/off, or they can be connected to Smart plugs, or TrolMaster 4RS-1 Outlet Expansion Module.   Customer Reviews John D.:  “My plants have never been healthier. The far-red light truly makes a difference." Sarah P.: Excellent quality! This light has transformed my growing setup."

What's Included With The Hydro-X System: Hydro-X Environment Controller (x1) 3-in-1 Sensor for Temperature, Light, and Humidity (x1) RJ12 Cable Set (x1) Male-to-Male 16ft RJ12 Cable (x1) Male-to-Male 4ft RJ12 Cable (x1) RJ12 T-Splitter (x1) Achieve Complete Grow Room Control With The Hydro-X With one piece of equipment, you can essentially control anything you need in your grow room. There are more than 17 separate types of control modules, granting you the ability to connect the Hydro-X to A/C's and HVAC  To put it simply, the TrolMaster Hydro-X Environment Controller With 3-in-1 Sensor is the most intelligent and versatile system on the market.  The Hydro-X System Features A Modular Design Another great feature of the Hydro-X Environment Control System is that you can control and customize every last detail of the controller. The modular design means you can configure the separate components in unique ways to create the best environment for your plants because every grow is different. You can control up to 512 different grow lights on two separate channels, and operate different systems simultaneously. Just about every lighting brand and product on the market is compatible with the Hydro-X with different adapters. LMA-11 for Phantom - Lighting Adapter P LMA-12 for Dimlux - Lighting Adapter D LMA-13 for Sun System - Lighting Adapter S LMA-14 Lighting Adapter F for most brands and also FGI brand LEDs LMA-15 for DLI - Lighting Adapter DLI LMA-T for ThinkGrow - Lantern Schedule Adapter F The LMA-14 Adapter can be used for 24 Drivers (LEDs) or 40 Ballasts with either the HCS-1 or HCS-2 Hydro-X controllers. Both the Hydro-X Controllers have 2 line lights giving the ability to control double the amount of each type of light (48 LEDs and 80 Ballasts).  

The LMA-14 lighting adapter is specially designed to control a wide variety of lighting systems including FGI brand LEDs and HIDs. TrolMaster’s Hydro-X system can control most of the horticultural lighting fixtures sold on the market today. Most light manufacturers provide the ability to control their lighting systems using what known as a low-volt control. That low-volt control can take many forms and communication protocols. TrolMaster makes several types of lighting adapters (LMA units) that allow the Hydro-x to control lights using their low-volt control option. 

Affordable, compact, extended far red spectrum LED grow light for plants of all types.    Growing tomatoe starts with the FGI Square 2   The FGI Square 2 is an excellent entry level LED grow light for those looking to give their plants the sun's energy. Unlike other lights on today’s market that only provide certain colors needed by plant life (or lack thereof), this one provides all the necessary components: red, orange, yellow green and blue spectrum which together make up the building blocks for successful photosynthesis (and closely matches our sun).  If you are looking for an easy to use LED to learn how to grow any plant types indoors, look no further than the FGI Square 2. Well loved by gardeners everywhere. Designed in the USA by Forever Green Indoors in Seattle WA. Plant lighting LED light experts since 2013. Use the Square 2 to grow all types of plants. Placing the light closer to the plants provides enough energy to match the summer sun. Pulling the light further away, or using the built in dimming, provides the right energy for starts and seedlings.  Learn more about the FGI Square 2 on our YouTube Channel here:  The Square 2 is one of the more efficient grow lights on today's market, using only 220 watts! This means it can produce far less heat than higher wattage lamps. We designed it to deliver the perfect balance of light. It's full spectrum white LEDs help plants grow healthy while adding 5% total deep as well as far-red diodes for an extended range that will optimize your plant growth! Key Features:  Compact size: 20" x 20" x 3" Lightweight: 10 lbs  Built in dimming knob: Adjusts levels for young to mature plants.  Spectrum: Full spectrum plus 5% 660nm deep red plust 730nm far red LED diodes.  Includes: 110V power cord. Two clip and steel cable wire hangars. Product manual.    Technical  PAR Chart at 24" From Diodes The right kind of light can make all the difference for your plants. Flowers, fruits and other high energy use types require levels as high as 1000 PPFD - a measurement that approximates natural sunlight. Spectrum From Our Sun   We design grow lights to closely mimic natural sunlight (shown above). Although it's not possible to exactly duplicate a giant burning ball of hydrogen, we get as close as possible with the Square 2.   Spectrum from the Square 2     Don't wait!

Elevate Your Plant Growth The FGI Far Red LED Grow Light is a top-tier solution designed to significantly enhance plant growth by delivering 730nm far red energy, which is crucial for optimal photosynthesis. Unlike cheaper 660nm red LEDs, which fail to produce this specific wavelength, the FGI light effectively stimulates growth processes that are otherwise neglected. Its robust, commercial-grade construction guarantees exceptional durability and consistent performance, making it the 730nm choice for both amateur and professional growers seeking to maximize their yields and improve plant health. Scientific Benefits Far-red light (700-760nm) is crucial for optimal plant growth, enhancing photosynthesis and increasing plant size. Studies, such as those from the University of Texas, show that “far-red light boosts overall plant mass and terpene profiles. It improves light absorption, influences leaf angle, and promotes higher yields.”  Read the study here. Far Red light is believed to create a competitive response in plants, pushing desirable terpene production and assisting in the formation of trichomes.   The Emerson Effect Using far-red light just before nighttime increases photosynthesis, cell division, and growth. Implementing a 10-15 minute far-red light cycle after full spectrum lights are off can optimize your growing environment. Recommended Use Ideal for 4x4 grow spaces, this light is easy to install with included hardware, ensuring full coverage and enhanced PPFD delivery. Controls With an low Amp draw at .3 amps, we recommend these units are operated on standard 110V receptacles. One dedicated 15 amp circuit can safely operate more than 30 units. Standard service outlets for fans can easily be used to operate as many units as needed. Standard wall timers can serve as on/off, or they can be connected to Smart plugs, or TrolMaster 4RS-1 Outlet Expansion Module.   Customer Reviews John D.:  “My plants have never been healthier. The far-red light truly makes a difference." Sarah P.: Excellent quality! This light has transformed my growing setup."
