Grow Lighting
Background: Our Story
Cannabis grow lighting is where we came from.
Since 2014, we have dedicated ourselves to engineering grow lights specifically for cannabis. This journey has been paved with experimentation, setbacks, and invaluable learning. We have experienced countless failures and killed thousands plants. Here are a few examples of our failures:
-
We tried red and blue photon-based spectra, only to see plants suffer and die.
-
We experimented with high ratios of red photons, which resulted in plant bleaching.
-
Attempts to precisely mimic HPS spectra using LED technology repeatedly fell short.
-
We were asked to develop a “one-size-fits-all” universal grow light with a single spectrum—a goal that proved unachievable.
-
We even tackled the design of an IP68-rated fixture for extreme environments, which presented its own set of difficulties.
Each failure taught us something new. Then, one day, a simple yet profound question we asked ourselves changed our approach: “Why not mimic sunlight?”
Inspired by this idea, we shifted to designing a white-light-based spectrum—and succeeded. We didn’t stop there. Through rigorous field testing in Los Angeles, Detroit, Washington (USA), Canada, and Israel, we replicated and refined this success. Continuous improvements followed, and by 2018, we began commercializing our specialized cannabis grow lights—proven, reliable, and designed to help plants thrive and yield. And this is actually why we called our spectrum technology as Sunlike+.
Background: Understand Cannabis Behaviors
One of the most important lessons we’ve learned is this: to grow effectively, you must truly understand the crop and its behaviors. Cannabis is a high-value plant that demands precise environmental control to maximize yield, optimize cannabinoid content, and ensure top-tier flower quality.
In today’s cultivation landscape, LED grow lights for cannabis have become essential in indoor and greenhouse settings, giving growers unmatched command over light spectrum, intensity, and photoperiod. Switching from conventional HID or HPS lighting to advanced LED technology brings benefits far beyond energy efficiency. It empowers cultivators to tailor light settings for each growth phase—from vigorous vegetative development to finely tuned cannabinoid and terpene synthesis during flowering.
This level of control is how modern growers achieve consistency, quality, and confidence in every harvest.
Challenges in Professional Cannabis Cultivation
-
Balancing Light Intensity and Plant Health
Cannabis requires high light intensity, but uneven distribution can create “hot spots” that stress plants. Excessive intensity can cause photobleaching, while low-light areas produce weaker, lower-quality buds. Uniform cannabis grow lighting systems are essential for stable crop performance.
-
Limited Canopy Penetration and Light Uniformity
Cannabis plants develop dense, multi-layered canopies where upper leaves absorb most of the available light, limiting penetration to lower bud sites. This results in underdeveloped “larf” flowers and reduces the overall yield of premium-grade cannabis. Achieving uniform PPFD distribution across the canopy is critical for maximizing production.
-
Spectrum Control for Cannabinoid and Terpene Production
Light spectrum directly influences plant morphology and chemical composition. An unbalanced spectrum can lead to excessive stretching and reduced terpene and cannabinoid development. Optimized LED grow lights for cannabis enable precise spectrum control for improved yield and product quality.
-
Energy Efficiency and Heat Management
Energy is one of the largest operational costs in indoor cannabis cultivation. Traditional HPS systems convert only about 30–35% of energy into usable light, with the rest released as heat.This increases HVAC load and operational costs.
Switching to energy-efficient LED grow lights for cannabis can reduce total energy and cooling costs by up to 40–50%.
Solutions and Best Practices
Like all plants, cannabis progresses naturally from seed through vegetative growth and flowering, culminating in harvest. In commercial cultivation, however, the cycle typically begins with clones for consistency and efficiency. At Richland, our grow lights are engineered to match the distinct requirements of each cultivation stage. We provide specialized lighting solutions—clone lights, vegetative lights, and flowering lights—to deliver precisely the spectrum and intensity your plants need, exactly when they need it.
-
Vegetative Lights & Flowering Lights
We have done a lot of research on the grow practice worldwide; finally, we have precisely sized the vegetative lights and flowering lights to fit the grow rack: in US and Canada, the light is designed at 43” x 47”; in Europe, the light is sized at 108cm x 108cm. With this, our cannabis grow lights can deliver uniform PPFD distribution across the entire canopy, ensuring that every plant develops at the same rate and reaches its full genetic potential.
-
Clone Lights
For the cloning stage, growers typically start plants on a smaller multi-tiered rack, often 60 cm x 120 cm in size. We have precisely designed a clone tube light that measures 120 cm (4 ft) in length. With three of these clone tube lights, you can easily achieve balanced light intensity and uniformity.
