The problem this solves

Plants evolved under the sun - not a single-spectrum LED panel.

Most grow lights miss key wavelengths like UVA and Far-Red, which drive resin production, flower ripening and canopy signalling.

The HORTIVISION 50W LED Enhance Bars bolt straight onto your existing fixture and inject those missing wavelengths back into the grow.

Two 25W bars deliver UVA, blue and far-red spectrum to push stronger flowering signals, faster ripening and higher-quality terpene production.

🔥 Why growers rate it

• UVA spectrum boost → stimulates resin and secondary metabolite production

• Far-red wavelengths → enhance flowering signals and accelerate ripening

• Blue spectrum support → improves plant structure and leaf health

• 50W supplemental output → strengthens photosynthetic activity across the canopy

• Clip-on mounting design → installs directly onto most LED fixtures

• Dual 25W bar configuration → even spectrum distribution across the grow space

• Sunlight spectrum simulation → mimics natural outdoor light signals plants evolved under

🌱 Grow Guys tip

Supplement bars like these are best used alongside full-spectrum LEDs during flowering.

Run them when your canopy is fully developed and plants are stacking buds. The extra UVA and far-red signals can help tighten up flower structure and push ripening signals right through the lower canopy.

🛠️ How to dial it in properly

Mounting position

Attach the bars directly to the frame of your main LED fixture.

This keeps the spectrum balanced across the canopy instead of blasting plants from one side.

Flowering stage timing

These bars are most effective during mid to late flowering when plants are producing resin and terpene compounds.

Coverage strategy

Use them to supplement the centre or outer edges of your main fixture where spectrum intensity drops.

Light scheduling

Run the bars alongside your primary grow light photoperiod.

Far-red supplementation works best when integrated into the main lighting cycle.

Pro tip

If your main fixture is heavy on white LEDs, these bars fill the spectrum gaps that drive flower maturation and terpene expression.

🧩 What it pairs with

Spectrum enhancers like the Hortivision bars work best when they’re part of a balanced lighting setup.

Pair them with a full-spectrum LED grow light as your primary canopy driver. The main fixture delivers photon density while the enhance bars fill in the spectrum signals plants evolved under outdoors.

You’ll also get the best results when the rest of the room is dialled. Proper airflow and canopy circulation help plants process higher photosynthetic activity without heat pockets building up around buds.

Finally, strong lighting only reaches its potential when plants are properly fed. Quality hydroponic nutrients and root-zone media like coco or rockwool allow plants to actually use the additional light energy you're delivering.

❓ Frequently asked questions

Do these bars replace a grow light?

No - they are designed to supplement your existing LED grow light.

The HORTIVISION LED Enhance Bars add targeted wavelengths like UVA and far-red that many fixtures lack, boosting spectrum quality rather than replacing your primary lighting.

What size grow light can they attach to?

They clip onto most LED fixtures up to 110cm wide.

This makes them suitable for the majority of grow tent fixtures and commercial LED frames.

When should I run the enhance bars?

Most growers run them during mid to late flowering.

That’s when plants respond strongly to spectrum signals that influence resin production, terpene development and flower maturation.

Do spectrum enhancer bars really make a difference?

Yes - when used correctly they improve spectrum balance.

Many LEDs focus on PAR output, but wavelengths like UVA and far-red influence plant signalling pathways that impact flowering behaviour and quality.

🚀 Give your LED the spectrum it’s missing

Most LEDs push photons.

These bars push plant signals.

If your current grow light is doing the heavy lifting but missing the wavelengths that influence ripening and resin expression, the HORTIVISION 50W LED Enhance Bars are a smart upgrade that slots straight onto your fixture and lifts the spectrum game.
