Reach the lower canopy
Add a supplemental light source below the canopy, where dense growth can limit the reach of overhead light.
COMMERCIAL CANNABIS LIGHTING
Bring light to the lower canopy. Explore a practical way to improve crop performance—and see what the economics could look like in your facility.

A DIFFERENT ANGLE ON YOUR CANOPY
As the canopy fills in, lower growth can receive less light. Under-canopy lighting adds a targeted layer of illumination—and a new variable to evaluate in your cultivation strategy.
Add a supplemental light source below the canopy, where dense growth can limit the reach of overhead light.
Consider yield and flower quality together. Compare a trial against your own baseline before planning a wider rollout.
Weigh potential crop value against fixture cost, installation, electricity, and the demands of your room.

FROM IDEA TO INSTALLATION
A good lighting plan considers the grower as well as the crop.
Talk to a Lighting ExpertBring your canopy dimensions, current yields, crop value, and cultivation schedule. A representative trial gives you a useful basis for comparison.
Review placement, dimming, electrical capacity, irrigation access, and day-to-day work around the crop. Fixture count is a layout decision, not just a floor-area calculation.
Additional lighting adds electrical load. Review HVAC capacity and monitor crop response, irrigation demand, and environmental conditions as you adjust your approach.
A FEW PRACTICAL ANSWERS
Have a question about your facility?
Talk it through with Thrive.
Under-canopy lighting places supplemental fixtures below the plant canopy to illuminate lower leaves and flower sites. It complements overhead lighting and should be planned around the crop, room layout, and cultivation strategy.
No. This application adds light beneath the canopy while overhead fixtures remain part of the lighting plan. Review the combined light distribution and operating schedule with a lighting designer.
Use your own trial results when available, and compare several scenarios—including no yield increase. Thrive’s published Boost XE page describes gains of up to 30%; that is not a guaranteed result for your facility. The calculator makes this an editable assumption and starts quality-mix improvement at zero.
Additional light can change crop demand and adds electrical heat to the room. Monitor the crop and growing environment, and review fertigation, irrigation, and HVAC capacity with your cultivation and facilities teams. The calculator does not separately model additional HVAC, nutrient, or labor costs.
The calculator uses editable coverage assumptions for early planning. Final quantity and spacing depend on canopy geometry, fixture placement, access, light distribution, and electrical limits. Thrive can help develop a layout for your specific room.
Neither. It is a planning estimate based on the assumptions you enter. Yield, quality mix, price, installation, rebates, and operating costs can materially change the outcome. Review the assumptions with Thrive before making a purchase decision.
