Low-profile LED strips that mount beneath the canopy to recover 15–30% of yield lost to shading — turning lower-branch larf into marketable flower.

LED tube grow lights are linear horticultural lighting fixtures designed for plant shelves, vertical farming systems, hydroponic racks, greenhouses, and propagation environments.
Unlike high-power bar grow lights that illuminate large cultivation areas from above, tube grow lights are compact, lightweight, and ideal for multi-layer growing systems where uniform light distribution and space efficiency are essential.
| Top canopy (0") | 800–1,200 μmol/m²/s |
| Mid canopy (12") | 300–500 μmol/m²/s |
| Lower canopy (24") — no under canopy | 100–200 μmol/m²/s |
| Lower canopy (24") — with under canopy | 300–450 μmol/m²/s |
Increase in harvestable weight from lower branches. The gain is almost entirely in what would have been larf or biomass-grade material.
Top-to-bottom light uniformity ratio improves dramatically. More uniform light means more uniform bud development and less trimming labor.
Typical payback period on under canopy strips. After that, the additional yield is pure margin — the per-gram cost is significantly lower than adding more top fixtures.
Five specs that separate a production-grade fixture from a hobbyist strip.
Under canopy lights run the same photoperiod as your top lights. Low efficiency turns into significant operating cost across 20–30 fixtures. Look for 2.5 μmol/J or higher at the system level.
The fixture must fit under a dense canopy without blocking airflow or crowding branches. Strip form factors are standard for a reason — they mount along trellis lines and produce even light distribution along the row.
White light alone can't penetrate lower canopy effectively. Deep red drives photosynthesis in shaded tissue. Far-red supports flowering initiation through the phytochrome response. If a fixture offers only white light, it's not optimized for lower canopy work.
Under canopy fixtures sit in the most humid part of the grow room — directly under transpiring leaves. IP65 is the minimum for long-term reliability in that environment. Sealed connectors are a must.
8–12 fixtures per driver run saves installation labor. A driver mounted outside the canopy zone means you don't have to reach through the crop to replace it. 0–10V dimming compatibility is standard for commercial integration.
