Fission Led 300W V2.0 Light – Full Spectrum, Silent & Dimmable

The Fission Led 300W V2.0 Light is the definitive lighting solution designed to transform your indoor cultivation into a high-performance system, offering a mixed spectrum that covers the entire life cycle of the plant with total silence and maximum energy efficiency. This equipment is not just a light; it is a precision tool that allows you to emulate the best of the sun inside your home, optimizing every watt to generate resinous flowers and vigorous growth in spaces up to 1m².

Why is lighting usually the biggest headache for growers?

Problem: If you've ever grown indoors, you know the drama: HPS bulbs that turn your tent into an oven, skyrocketing electricity bills, and plants that stretch looking for light or end up with airy, weightless buds. It's frustrating to invest time and nutrients only to have the lighting fail you.

Agitation: There is nothing worse than seeing your plants stressed by heat or hearing the constant hum of fans trying to cool a cheap lamp. Staying with obsolete technology or low-quality LEDs limits your results, leaving you stuck in a cycle of mediocrity where you never quite reach that "magazine quality" harvest you dream of.

Solution: The Fission Led 300W V2.0 Light eliminates these problems at the root. Its passive cooling technology means zero noise and significantly less heat, while its high efficiency (2.4 µmol/J) ensures that every photon is used by the plant. It is the upgrade that allows you to move from "surviving" to truly thriving.

If you're just starting out: how this product helps you

Starting an indoor grow can be intimidating, but this LED makes it incredibly simple. You don't need to be an electrical engineer or a master grower to get great results. Its "Plug & Play" design and the ability to regulate power mean the light adapts to you, not the other way around. It's forgiving if you make mistakes and safe to handle.

• Easy installation: It comes ready to hang and turn on, without complicated ballasts.
• Total control: The dimmer allows you to start at 40% for seedlings (saving light) and go up to 100% for flowering.
• Less heat: You won't have to fight constantly against temperature, making climate management much easier.
• Full cycle: You don't need to change bulbs; the same spectrum works for growth and flowering.

If you already have experience: why it deserves a place in your kit

For the veteran grower, the Fission V2.0 offers the nuances that make the difference between a good harvest and an exceptional one. We are talking about a spectrum that includes UV (395nm) and IR (730nm), essential for stimulating the production of secondary metabolites (terpenes and cannabinoids) and the Emerson effect for faster photosynthesis. It is a 300W Grow light LED designed to squeeze the genetic potential of your strains.

• Specific spectrums: The inclusion of UV and Far Red boosts resin and root mass.
• High PPFD: With 720 µmol/s, you ensure high light penetration, reaching even the lower buds.
• Passive dissipation: No moving parts means a longer lifespan (>50,000 hours) and zero maintenance.
• Versatility: Perfect for a 100x100 cm tent or to reinforce larger spaces.

Advantages and benefits for any level

• Silence is golden: Being fanless, it is completely silent, perfect for discreet domestic crops.
• Energy savings: Consumes significantly less than an HPS equivalent while producing more assimilable light.
• Adjustable Dimmer: 40%, 60%, 80%, and 100% settings to mimic the seasons and save on the bill during the vegetative phase.
• Deep penetration: The distribution of the diodes ensures that light reaches the lower branches, reducing "popcorn buds".
• Durability: IP65 protection against moisture and dust, essential in the humid environment of a grow tent.
• Ideal size: Its dimensions are perfect for standard tents, and it even fits snugly in Grow tents 80X80 for those who want maximum light intensity (CO2 recommended in this case).

Typical mistakes this product helps you avoid

Even with the best equipment, mistakes happen. The Fission V2.0 is designed to minimize the most common failures in lighting management.

• Burning the plants: By running cooler than HPS, the risk of thermal stress is drastically reduced.
• Wasting light: The 120° opening angle ensures light goes to the plants, not the walls.
• Light stress in seedlings: Thanks to the dimmer, you avoid frying young plants with too much intensity; just set it to 40%.
• Inconsistent photoperiods: Compatible with any Indoor light timer, ensuring your plants sleep and wake up when they should.

Frequently Asked Questions

At what distance should I hang the Fission LED 300W?

We recommend about 40-50 cm during growth and bringing it closer to 30-40 cm during flowering. Always watch the tips of the plants; if they curl up, raise the light a bit.

Is this LED enough for a 1.20 x 1.20 meter tent?

It can work for vegetative growth, but for explosive flowering in that space, you might fall a bit short on the edges. It is optimized for 100x100 cm. For 1.20m, two units or a more powerful model would be ideal.

Does it include UV and IR light?

Yes, the V2.0 version incorporates 395nm (UV) and 730nm (IR) diodes, which helps improve trichome production and plant morphology compared to basic white LEDs.

Do I need to install extra fans for the light?

No, the aluminum heat sink manages the temperature passively. However, you always need good extraction in your tent for the plants to breathe.

Personal Experience of Pevgrow’s CEO (Alan)

"If you ask me what light to buy to start seriously without spending a fortune, the Fission 300W V2.0 is usually my first answer. I've tested it in a 1m² closet with 9 plants, and the difference in resin compared to older models is noticeable thanks to those UV diodes. What I enjoy the most? The silence. Opening the tent and not hearing that annoying fan hum is a luxury. For beginners, my advice is simple: don't get obsessed with putting it at 100% from day one. Start low, let the plants ask for more, and you'll see how they reward you with rock-hard buds."
