GREENHOUSE CULTIVATION

Proven Results in Cannabis Greenhouse Applications

GrowRay’s lighting systems provide supplemental lighting for greenhouse at half the energy cost of traditional HPS lights. GrowRay lights substantially increase yield, improve plant health, benefit root structure and reduce the crop growing cycle. GrowRay manufactures the world’s best supplemental lighting solution for cannabis greenhouse applications:

  • GrowRay’s unique patent pending design reduces shading to only 8%, leading the industry.
  • GrowRay’s patent pending adaptive controller turns lights on only when needed and the minimum amount required.
  • GrowRay’s supplemental lighting solution utilizes the maximum available sunlight before ​coming on, to minimize energy costs while ensuring best growth and photomorphogenic results.

ADAPTIVE CONTROLLERS FOR GREENHOUSES

Produce the Correct DLI for Optimal Plant Health

GrowRay adaptive controller / sensors optimize lighting throughout a greenhouse. Each luminaire has its own sensor, effectively providing plants with their own “light meter.”  If a particular section of a greenhouse is shaded from the early morning sun, GrowRay lights adjust to provide the plants with ideal level of light. At the same time ​lights on the eastern side of a greenhouse would be dimmed or off. This reduces energy consumption significantly and provides plants with the correct DLI (Daylight Integral) at all times.

GrowRay’s adaptive controllers / sensors adjust light intensity in real time, based on available sunlight. If full sunlight is is available, GrowRay LEDi fixtures are automatically turned off.  If the sun is dimmed, lights are turned on in a linear fashion, with just a little for a passing cloud, to full on for a rainy day, or short winter days. Adaptive dimming thresholds are factory set for 200 to 600 PAR as standard.  Maximum is 1000 PAR , or may be user modified within this range.  GrowRay adaptive sensors provide plants with the correct DLI for optimal growing results.

MAINTAIN PERFECT LIGHTING AUTOMATICALLY

GrowRay adaptive controllers ensure optimum light levels throughout the entire crop cycle while minimizing the amount of energy expended.  This is how:

  1. ​Grower uses personally obtained or published lighting profiles for individual crops.
  2. Purchases pre-set adaptive controllers for recommended light levels (PPFD levels of 200 to 1000), or sets ​(if necessary) the ones he already owns.
  3. Then:  The adaptive controllers measure the sunlight level, real-time and adjust the amount of light produced to achieve the optimal light intensity at all times (see chart​ to right).

ADAPTIVE CONTROLLER / SENSOR

GrowRay’s self-contained, Adaptive  Controller / Light Sensor (patent pending) optimizes light levels in greenhouses to provide the perfect supplemental lighting.  In one field test GrowRay fixtures with adaptive sensors reduced electricity consumption 80% while producing an 18 % higher cannabis yield compared to HPS results.

GrowRay’s adaptive sensors adjust light intensity in real time, based on available sunlight. If the sun is brighter than a predetermined threshold, the GrowRay LEDi lights are turned off. Below this threshold,  lights are turned on in a linear fashion, from just a little for a passing cloud, to full on for a rainy day, or winter weather. This threshold is factory set for 200 to 600 PAR, depending on the plant, or may be user modified.  GrowRay sensors and lights work to provide the grower with the correct DLI (Daylight Integral) for best growing results.

REDUCED SHADING

Maximize ​Available Sunlight

Many greenhouse growers refuse to use supplemental lighting even though they know it can extend the growing season and even provide additional ones. Why? In greenhouse environments supplemental lights will block a significant percentage of sunlight. This means that the supplemental lights have to be turned on more frequently to offset the shadows they create, causing a big bump in their electric bills and more labor tracking when the lights should be on, or poor plant growth if forgotten.

GrowRay’s patent pending luminaires minimize the loss of available sunlight. At only 8% shading, GrowRay offers the smallest shadow of any light on the market. One look at the non-streamlined shape of competing lights tells the story–large shadows covering valuable plant canopy. Other brands hide their true shading numbers by claiming that their lights can be placed under existing struts or beams. This is an impractical and unrealistic solution in most greenhouses. GrowRay’s unique shape passively reflects sunlight to the canopy below. This allows plants to receive the maximum available daylight in almost every greenhouse environment.

SINGLE BAR LIGHTING

Increases Yield 10% To 30%

Single bar lighting augments sunlight and multi-bar lighting to ensure even PAR throughout plant canopy. Single bar lighting can provide additional light to increase plant growth in rooms where multi-bar systems are mounted high above the canopy. Single bar systems can also be used to brighten up dark corners, behind weight bearing pillars, and wherever structural  barriers block the sun. Tight growing spaces can also block overhead lights or sunlight from penetrating as deeply into the canopy.  In any situation where a portion of a tray is under lit, single bar lighting is an excellent solution.

GrowRay single bar lights can be hung or be held by a heavy duty gooseneck clamp (available from GrowRay), on a bendable extension to ensure ideal placement.  With effective placement, single bar lighting can expand crop yield from 10%-30%:

  • ​Horizontally, adjacent to the canopy on the edges or in the center of the room
  • ​Vertically, adjacent to the canopy in corners, behind structural sunlight barriers, or inside the canopy itself
  • ​Back to back side-lights, side lighting trays on both sides of an aisle

Customer Testimonial

“We have added GrowRay single bar lighting to my existing  test grow.  We determined where PAR was below optimum and added side lighting and supplemental top-down lighting to bring PAR back to ideal levels in the canopy and add additional PAR to the sides of our 4’x4’ SCROG setups.  We determined that adding this additional light and adjusting our pruning to take advantage has increased dry weight per square foot between 10% and 30%, by improving growth and density of the peripheral flowers.  The side flowers also showed visibly increased trichomes.  In addition to the additional dry weight, and trichome production another great benefit is that our bloom cycle has been consistently reduced by up to 7 days, translating into additional output per square foot annually.  Having these LEDis also has helped to identify plant deficiencies earlier due to the spectrum providing better visible light than the standard yellow wash of HPS.” Customer Testimonial – 2017-2018, 4 Cycles, 6 strains.
