Who This Is For
- You are adding under-canopy lighting because your top-down lights cannot reach the bottom third of your tall crop.
- You are investing in targeted lighting because shadowed lower zones are producing subpar flower and biomass.
What We Found
- The 160 degree beam angle is wide enough that you can space these out without leaving dark gaps in the lower canopy.
- The mounting poles included in this kit feel much sturdier than the flimsy plastic clips we see on cheaper lights.
What Users Say
- Commercial teams using the daisy chain feature say it kept their floors clear of the cord clutter typical of LED rows.
- Growers who installed these reported that the lower flowers reached the same density as the tops by harvest time.

FAQs
What is under-canopy lighting and why do I need it?
Under-canopy lighting is a supplemental light source placed low in the grow space to illuminate the parts of the plant that are typically shaded by the upper canopy. This helps boost the development of lower flowers and leaves, leading to more consistent growth and higher overall yields.
How many SubFlux120 lights do I need for my space?
We recommend using two SubFlux120 light bars (one 2-pack) per 4' x 4' grow area for optimal coverage. This ensures that the lower canopy receives uniform and intense light from multiple angles.
Can I connect these lights to a controller?
Yes, the SubFlux120 is fully dimmable and can be controlled via an external 0-10V dimmer dial or a compatible lighting controller for precise management of your light cycles and intensity.
Are these lights suitable for humid environments?
Absolutely. The SubFlux120 has an IP65 rating, which means it is water-resistant and protected against dust ingress. This makes it perfectly safe and reliable for use in the high-humidity conditions common in grow tents and commercial grow rooms.
How do these compare to other HortiBloom grow lights?
The SubFlux120 is a specialized supplemental light. While primary overhead lights from the HortiBloom lineup provide top-down coverage, the SubFlux120 targets the lower, often-neglected parts of the canopy. Using them together creates a comprehensive lighting environment for maximizing your harvest.
