Insights

Agritech Product Strategist

New under‑canopy light claims to improve lower-bud quality and raise harvest yields for commercial cannabis growers.

The product links a tunable Full Spectrum + Far Red + UV output to lower canopy zones and sells at $179 MSRP per fixture. The release reports early trials showing up to 35% yield increases, 5–7% flowering time reduction via a Short-Cycle™ recipe, and features suited for commercial racks and tables.

This works by supplying photons below the canopy where light normally attenuates, which can stimulate photosynthesis and secondary metabolite pathways in lower buds. The claims align with the described mechanism, but independent validation of the reported 35% figure and maturation gains remains necessary before treating results as confirmed.

Key dependencies include real-world adoption rates, fixture density needed per table, and the durability of claimed effects across cultivars and cycles; these details determine commercial and margin impact. Monitor unit sales, distributor uptake through licensed stores and the B2B portal, and any independent trial data confirming the 35% yield improvement and the 5–7% faster flowering across multiple harvest cycles in the near term.

New lighting technology delivers full-spectrum, Far Red, and UV light beneath canopy to increase yield, boost flavor, enhance aroma, and improve overall flower quality for commercial cultivators

DENVER, Oct. 29, 2025 (GLOBE NEWSWIRE) -- GrowGeneration Corp. (NASDAQ: GRWG) (“GrowGen” or the “Company”), the nation’s largest specialty hydroponic and organic gardening retailer, today announced the launch of its Dialed In™ Tri-Spec Under Canopy Light, a first-of-its-kind lighting solution engineered to boost lower-canopy flower development in commercial cannabis cultivation.

The Dialed In™ Tri-Spec system delivers a tunable spectrum of Full Spectrum, Far Red, and UV light directly beneath the canopy to activate photosynthesis, anthocyanin development, and secondary metabolite production from the bottom up. This system helps cultivators address a universal issue, penetrate lower buds which are typically smaller, less potent and often unsellable due to the spectrum of light stopping at the top of the canopy. Early trials reported up to 35% yield increases, faster maturation, and stronger terpene expression — resulting in better flavor, richer aroma, and a more uniform, high-quality flower from top to bottom.

“For decades, growers have typically accepted that the bottom 30% of the plant produces less due to the lower parts often being smaller and underdeveloped,” stated GrowGeneration President and Co-Founder, Michael Salaman. “With Dialed In™ Tri-Spec, we turn that lost canopy into profit as we are now able to increase the spectrum of light across the entire plant helping to boost flavor, aroma, and overall flower quality without adding time to the grow cycle. We are excited about the launch of the Dialed In™ Tri-Spec and look forward to helping growers generate better yields and deliver a higher quality product.”
