February 17, 2023 - Nice little boost that helps even out the growth, though had to do a little extra work to keep the temp down. ... There's some good research from Jumplights that shows that under canopy can increase premium flower weight by up to 60%. It does ...

September 25, 2025 - Explore the science and effectiveness of under-canopy lighting in cannabis cultivation. Learn how this innovative technique can boost yields by up to 25-35% while maintaining quality through a holistic approach to grow room management.

April 30, 2026 - Under canopy lighting is a purpose-built LED system installed beneath the cannabis canopy, delivering high-efficiency photons directly to shaded lower bud sites.

June 30, 2025 - This Improved light penetration ... Under canopy lighting stimulates flowering and resin production in lower and inner bud sites that may be shaded or receive less light from overhead grow lights....

November 27, 2023 - When growing indoors, lighting that sits permanently above plants can exacerbate this imbalance, meaning lower bud sites become underdeveloped. Side lighting, or lighting under the canopy, can remedy this.

May 15, 2026 - By illuminating the lower bud sites that are otherwise remaining shaded, the under canopy lighting unlocks basically this additional harvestable biomass. It supports higher grams per square foot without expanding the facility footprint.

November 3, 2025 - Under canopy lighting — also known as bottom lighting or under canopy LED lighting — is becoming a popular grow room upgrade among experienced cultivators. It’s designed to illuminate the lower parts of your plants, where traditional overhead lights can’t penetrate effectively.

July 31, 2026 - Under-canopy lighting (UCL) reliably increases usable yield and bud quality in indoor and commercial cannabis grows when paired with proper environmental control.

June 17, 2026 - Research from the University of Guelph found that supplemental sub-canopy lighting brought lower bud cannabinoid and terpene content in line with top colas — effectively eliminating the quality gap between top and bottom of the plant.

February 19, 2026 - From a technical standpoint, under-canopy lighting works by delivering targeted light to the lower parts of the cannabis plant that typically receive minimal light due to shading from upper foliage.

May 6, 2026 - Under canopy lighting increases cannabis yields by 20–30% by delivering supplemental light to lower branches that are traditionally shaded by the upper canopy. This technique improves flower density, boosts chlorophyll production by 10%, and ...

May 12, 2026 - JumpLights Catalyst® Pro sets a new standard in under canopy lighting with higher output, better light directionality, and a balanced spectrum engineered specifically for cannabis cultivation.

April 1, 2026 - In in terms of increasing yield, I expect so because we know that adding light to a plant when leaves are below the light saturation point will tend to increase net photosynthetis and growth.

August 15, 2026 - Under-canopy LED lighting places low-wattage LED bars beneath the plant canopy, pointing upward to illuminate lower leaves and bud sites that overhead lights can’t reach. Commercial growers consistently report 20 to 35% yield increases, better bud quality, and improved cannabinoid profiles.

September 1, 2026 - Under-canopy bars solve this by moving the light source to where it's needed: below the canopy line, angled up and inward toward the interior bud sites. The right supplemental output depends on where you are in the growth cycle.

February 7, 2025 - In another study published in 2018, researchers discovered that intracanopy lighting for medicinal cannabis cultivation improved light distribution and led to quantifiable enhancements in crop yield and quality. The study specifically reported that integrating LED interlighting resulted in a substantial increase in 'A' class flowers, accompanied by a notable five percent increase in THC levels across the crop. This targeted under-canopy lighting approach also yielded a higher overall crop output, with a reported increase in dry flower weight from 0.27 gram/mol under standard HPS lighting to 0.37 gram/mol when combined with LED interlighting.

August 22, 2024 - This new way of growing indoors brings many benefits. It uses canopy lighting to improve indoor cannabis cultivation and grow room setup. It helps increase yields, spread light evenly, and control the environment better.

July 22, 2025 - As your cannabis plants grow, regularly ... of growth. Under canopy lighting refers to placing lights beneath the plant canopy to illuminate areas that top lighting does not reach....

March 19, 2025 - While canopy lighting is no substitute for traditional overhead lighting, it can serve as a powerful supplement that effectively doubles the productive canopy footprint. By increasing light exposure to both the top and bottom layers, growers can enhance yields and cannabinoid production. One ...
