Fission Led 720W Complete Lighting · Full Spectrum & High Efficiency

The Fission Led 720W Complete Lighting is the definitive leap towards professional cultivation you've been looking for, a 6-bar beast designed to cover every square centimeter of your grow tent with high-quality photons. This system is not just a light; it is a precision tool that offers a full spectrum (Full Spectrum) ideal for the entire life cycle of your plants, guaranteeing denser flowers, more resin, and energy efficiency that will make you forget about old sodium bulbs forever.

Is lighting complicating your life?

We know the feeling: you look at your crop and don't know if you're falling short on light, if you're burning the tips, or if your electricity bill is going to skyrocket without getting the gram-per-watt ratio you expect. The lack of a clear protocol and efficient equipment often leads to improvisation, and in this game, improvising usually means losing money and time.

The consequences are frustrating: plants that stretch looking for light, airy buds without density, and heat problems that force you to install extra air conditioning. It's disheartening to put in so much effort for a mediocre harvest just because you didn't have the right technology or didn't know how to adjust the power at the exact moment.

The Fission Led 720W solves this equation instantly. It is designed to be plug-and-play, with a dimmer that allows you to give the plant exactly what it needs at each stage, without excess heat and with a distribution that mimics sunlight. Below, we present a step-by-step guide so you can master this equipment from day one.

Phase 1: Preparing the ground

Before hanging this beast, you need to ensure your workspace is ready to handle 720W of pure light power. Although LEDs emit less heat than HPS, this equipment is powerful and requires a suitable environment.

• Check your space: Ideally, use LED Grow Tents of at least 1.20m x 1.20m, although it performs best in 1.50m x 1.50m to cover the perimeter well.
• Ventilation: Ensure you have an extractor capable of renewing the air; plants under powerful LEDs transpire more and need CO2.
• Support: Verify that the structure of your tent can support the 8.2 kg of the unit.
• Distance: Have quality pulleys (ratchets) ready to adjust the height easily.

Phase 2: Setting up the product

The Fission Led 720W stands out for its foldable and compact design. You won't need an engineering degree to get it running.

1. Unfolding: Carefully take the equipment out of the box and unfold the two sections until the 6 bars are completely flat.
2. Hanging: Attach the steel hangers to the anchor points on the frame and hook them to your pulleys.
3. Driver connection: The ballast is integrated into the frame, which simplifies things. Make sure the connection cable is tight.
4. External control (Optional): If you are going to use a controller for several units, connect the RJ12 cable to the input port.
5. Power on: Plug it into the mains. Ensure the dimmer is set to the minimum before turning it on to avoid blinding yourself or stressing small plants.

Phase 3: Use / growing step by step

This is where the magic happens. Follow this roadmap to maximize the 2.7 µmol/J efficiency of your Fission Led.

1. Seedlings/Clones: Start with the dimmer at 25% or 40% power and place the light about 60-80 cm away. They don't need intensity, just presence.
2. Vegetative Growth: As they grow new leaves, increase to 50-60% and lower the light to 40-50 cm. You want them to grow compact, not stretched.
3. Pre-flowering: When changing the photoperiod, turn it up to 75-80%. The plant needs energy for the "stretch".
4. Fattening (Bloom): This is the moment for 100%. Lower the light to about 20-30 cm (monitor the temperature at the tips). The 1940 µmol/s will make the buds explode.
5. Final ripening: You can reduce to 80% in the last week to preserve terpenes and simulate the autumn sun.
6. Observation: If you see leaves curling upwards (canoeing), raise the light or lower the intensity; you are saturating them.

Phase 4: Closing, maintenance and learnings

Once you've harvested those rock-hard buds, don't just turn off the light and leave. To ensure the 50,000-hour lifespan, wipe the bars with a soft cloth and a little isopropyl alcohol to remove dust or resin splashes (always with the equipment cold and unplugged). Keeping the diodes clean ensures that light penetration remains identical for the next crop.

Take note of the height and power that worked best for your specific strain. Mastering the Fission Led 720W is about finding that "sweet spot" where your plants pray to the light without getting stressed.

Advantages of following this flow instead of improvising

• Consistency: You will avoid the "yo-yo" effect of light stress that stalls growth.
• Energy savings: You won't use 100% power when the plant only needs 50%, saving on your bill.
• Thermal control: By adjusting power gradually, you manage the temperature inside the tent better.
• Maximum gram/watt: You optimize the PPF (photon flux) so the plant transforms every photon into tissue.

Frequently Asked Questions

Does this LED generate a lot of heat?

Compared to an HPS, it generates much less heat, but 720W is a lot of power. Its passive thermal management dissipates heat efficiently, but you should always maintain good air extraction.

Can I connect multiple Fission LEDs together?

Yes, it has RJ12 connectivity that allows you to daisy-chain multiple units and control them from a single master controller, ideal for larger rooms.

Is it suitable for the entire cycle?

Absolutely. Its spectrum is mixed (White + Red 660nm), designed to cover vegetative growth and stimulate explosive flowering. It is one of the most versatile Indoor LED Grow Lights 800W category options (in terms of performance range).

Personal Experience of Pevgrow’s CEO (Alan)

When I first tested the Fission Led 720W, I admit I was skeptical about whether it could rival more expensive brands. My surprise was huge when I saw the uniformity of the canopy; the side buds were almost as hard as the central ones, something that is hard to achieve with other lights. I organize my phases by being very conservative with the dimmer during the first few weeks; I prefer to fall short and correct than to fry the seedlings.

A mistake I made at the beginning was putting it too close too soon, thinking "more light is better." I learned that with 720W, distance is your best friend. Now I keep it at 40cm in full bloom and the results are spectacular, with a resin production that seems like it's been sugared.
