Galaxy PRO 640W UVFR LED System – Full Spectrum with UV & IR Control

Take your indoor cultivation to the professional league with the **Galaxy PRO 640W UVFR LED System**, a lighting beast designed to squeeze every last drop of genetic potential from your seeds. This is not just another LED; it is a precision tool that gives you total control over the spectrum, allowing you to mimic the sun's behavior to boost resin production and bud density like you've never seen before.

Is your lighting limiting your harvest's potential?

Are you tired of putting months of effort into your crop only to harvest buds that look decent but lack that rock-hard density and overflowing trichome coverage you see on social media? It’s a common frustration: you have good nutrients and good genetics, but the final result feels "flat."

The problem usually isn't your skill, but the light spectrum. Standard LED lights often miss the "edges" of the spectrum—Ultraviolet and Far Red—which are crucial for triggering the plant's defense mechanisms (more resin) and the Emerson effect (faster photosynthesis). Without these wavelengths, you are leaving grams and potency on the table, wasting electricity on a harvest that could be legendary.

The **Galaxy PRO 640W UVFR LED System** solves this immediately. By integrating dedicated and adjustable chips for UV and IR, this system allows you to "stress" the plant in a positive way to generate more cannabinoids and terpenes, while the Far Red accelerates flowering and increases biomass. It's the missing link between a good harvest and a cup-winning one.

Why the Galaxy PRO 640W UVFR changes the game

This system stands out in the crowded market of Full spectrum led grow lights because of its versatility and raw power. It is designed for growers who know that details make the difference.

• Total Spectrum Control: Unlike fixed fixtures, here you can adjust the UV and IR. Use UV in late flowering to boost trichomes and IR to stimulate cell expansion and bulk up the flowers.
• Market-Leading Efficiency: With an efficacy of 2.97 µmol/J, you get massive light output (PPF of 1867 µmol/s) without the insane electricity bill of older HPS systems.
• Premium Components: Built with Samsung and Osram chips, ensuring durability, spectral stability, and minimal light decay over time.
• Perfect Coverage: Its multi-bar design ensures uniform light distribution, eliminating hot spots and shadows. It covers a 1.2x1.2m area for intense flowering or up to 1.5x1.5m for vegetative growth.

Technical advantages that turn into real results (FAB)

Understanding what this beast does will help you get the most out of it:

• Feature: Adjustable dimmer (40% to 100%) and independent UV/IR channels.
  • Advantage: You can tailor the light intensity and spectrum to the exact week of the life cycle.
  • Benefit: You save energy during the seedling phase and unleash maximum power during fattening, resulting in heavier and stickier harvests.
• Feature: Passive thermal management (fanless design).
  • Advantage: Operates in total silence and generates less heat than HPS or lower-quality LEDs.
  • Benefit: Easier temperature management in your Indoor grow tent kit, reducing the need for massive extraction and keeping your plants stress-free.
• Feature: Driver compatible with 0-10V controllers.
  • Advantage: Allows you to connect multiple units and control them centrally (daisy chain).
  • Benefit: Scalability for professional setups, saving you time on manual adjustments.

How to use the Galaxy PRO 640W for maximum yield

To get those rock-hard buds, follow these tips when setting up your new 600w Grow light LED category fixture:

1. Vegetative Stage: Keep the dimmer around 40-60% and hang the light about 60-80cm from the canopy. Keep UV/IR off or very low to encourage compact growth without stretching.
2. Early Flowering: Crank the power to 80-100%. Introduce Far Red (IR) to trigger the Emerson effect, speeding up the transition to bloom and stretching the cells for bigger bud sites.
3. Late Flowering (Ripening): Maintain 100% power. This is where you boost the UV. The ultraviolet light tricks the plant into thinking it's high in the mountains, forcing it to produce a thick layer of resin as "sunscreen."
4. CO2 Supplementation: Since this light is so powerful (PPFD > 1000 µmol/s/m²), if you run it at 100% close to the canopy, adding CO2 will help your plants process that extra light and explode in size.

Frequently Asked Questions

Does the UV light hurt the plants?

No, if used correctly. The Galaxy PRO is designed to provide the right amount of UV to stimulate resin without burning the plant. However, avoid looking directly at the light when UV is on to protect your eyes.

What is the ideal hanging height?

For flowering, aim for 30-50cm above the canopy. For vegetative growth, 60-80cm is sufficient. Always monitor your plants for signs of light stress.

Can I use this light for the entire cycle?

Absolutely. It is a full-cycle fixture. From seedling to harvest, you just need to adjust the intensity and the specific UV/IR channels.

Personal Experience of Pevgrow’s CEO (Alan)

I've tested dozens of bar LEDs, but the Galaxy PRO 640W UVFR really surprised me with its versatility. The ability to manually toggle the UV and IR gives you a feeling of control that standard full-spectrum lights just don't offer. In my test run, I noticed a significant difference in the smell and stickiness of the flowers during the last two weeks when I cranked up the UV channel.

My trick? Don't overuse the IR during the first two weeks of flowering if you are growing a strain that stretches a lot (like Haze), or they might get too tall. But for Indicas, blast that IR to get massive colas. It’s a serious piece of equipment for growers who want to graduate from "good" to "top-shelf."
