Under-canopy LED lighting is becoming essential in serious indoor cultivation because modern gardens are built around dense, high-intensity top lighting. As canopies thicken, the lower third of the plant becomes shaded, reducing photosynthesis, slowing development, and producing small, underdeveloped fruit or flowers. Under-canopy LEDs solve this by delivering targeted light to the zones that overhead fixtures can’t effectively reach.

By increasing light penetration from below, growers improve lower-site productivity, balance plant energy distribution, and reduce larfy or immature growth. This leads to more uniform development across the entire plant, not just the top canopy. Better light distribution also improves airflow through the lower structure by encouraging stronger, healthier branching rather than weak, shaded growth.

For serious indoor growers running high PPFD environments, under-canopy LEDs aren’t about adding more light — they’re about improving light efficiency. When every square metre matters, optimising lower canopy performance can significantly increase overall yield, consistency, and crop quality.
