U120C under canopy grow light with full-spectrum diodes

What an Under Canopy Grow Light Actually Changes

Your main fixture cannot bend light around leaves. An under canopy grow light attacks from below – the U120C throws full-spectrum diodes full-spectrum light up into bud sites that spend their lives in shade, pulling the lower third of each plant into production.

  1. Weight where there was waste. Lower bud sites that would finish as larf develop into dense, saleable flower.
  2. full-spectrum diodes quality. The same premium diodes as top-shelf fixtures, pointed at the neglected half of your plant.
  3. Slim, plant-safe profile. Low heat and a flat housing sit close to stems without stress.
  4. Zero workflow change. Wire it to the same timer as your main light and forget it.

Does an under canopy grow light really increase yield?

It converts existing larf into developed flower – growers typically see meaningful lower-third improvement. It amplifies a good setup; it cannot rescue a weak top light.

When should it run?

Match your main light's flowering schedule – same timer, same 12/12.

Will it burn lower leaves?

Low heat and distance make that unlikely; keep 15-20cm from the nearest foliage.

Running cost?

0.12kWh per hour – about R4-R5 per 12-hour day (Eskom tariffs).

One unit or two?

One for tents to 120x120cm; pair them beyond that to keep under-light even.
