What is the Pro Grow UFO LED Grow Light used for?
Pro Grow UFO is a full-spectrum LED designed for all plant stages—seedlings, veg, flower, herbs, and houseplants. It’s ideal as a main light in compact tents or a powerful supplemental light in larger setups.
What sizes does the Pro Grow UFO come in and how do they differ?
It comes in 100W, 200W, 300W, and 500W models. The 300W and 500W versions are dimmable and support controller integration. Higher wattages offer more intensity, cover larger areas, and weigh more.
What grow area does each Pro Grow UFO model cover?
Roughly: 100W = 0.5×0.5m, 200W = 0.75×0.75m, 300W = 1×1m, 500W = 1.2×1.2m. Suitable for tents, rooms, under-canopy, or corner-fill lighting. Compact size makes them easy to hang even in low-height setups.
Is the Pro Grow UFO truly full spectrum with red and far-red?
Yes—it uses a 4000K white base with 660nm red and 730nm far-red diodes. This spectrum supports full-cycle growth and can improve flowering, canopy behaviour, and overall plant health.
How efficient is the Pro Grow UFO and what is its CRI?
It’s rated at ~2.1 µmol/J for solid efficiency in its class. A high CRI (~90) means natural-looking plant colors, making it easier to spot stress, pests, or deficiencies.
How high should I hang the Pro Grow UFO above plants?
Start higher than 15cm and watch plant response. Signs of being too close include leaf curling, bleaching, or crispy tips. Stretching or pale growth may mean it's too far. Adjust height or dimming as needed.
Which Pro Grow UFO models are dimmable and how does it work?
The 300W and 500W models have manual dimming and support external control via the Pro Grow Smart Controller. You can daisy-chain multiple units for centralized adjustments if needed.
Does the Pro Grow UFO get hot or make noise?
It runs cooler than HID and uses passive (fanless) cooling, making it silent. Still, all watts create heat, so proper ventilation in your grow space is essential.
Is the Pro Grow UFO easy to install and power?
Yes—it’s plug-and-play on standard 240V. Power draw ranges from ~0.42A (100W) to ~2.08A (500W). Use strong rated hangers and keep cables neat for safety and performance.
How durable is the Pro Grow UFO in humid grow tents?
It’s IP55 rated for water and dust resistance, with an aluminium body for strength and heat dissipation. Suitable for high humidity—just avoid spraying directly on the fixture or letting water pool near plugs.
How do I clean and maintain the Pro Grow UFO?
Unplug it, let it cool, then wipe with a dry or slightly damp cloth. Keep lenses and housing free of dust to maintain output and prevent heat buildup.
What light schedule should I use with the Pro Grow UFO?
Most growers run 18/6 for veg and 12/12 for flower. While 24/7 is possible in veg, most plants benefit from a dark period. Use a timer for consistency and avoid accidental light stress.
Will my plants need more water or nutrients with this light?
Likely yes. Better light means faster growth, which increases water and nutrient needs. Watch for signs and increase feeding gradually rather than all at once.
Can the Pro Grow UFO improve flower density and reduce stretch?
Yes—when set up correctly, its strong, even light can reduce stretch and support tighter, denser flower formation. CO₂ is not required, but can be useful at high light intensity with controlled environments.
Is the Pro Grow UFO safe for eyes and foliar sprays?
It’s bright—avoid direct eye exposure. Use grow glasses for long sessions. For foliar sprays, turn off the light first and let leaves dry before powering back on to avoid leaf burn or fixture damage.
What’s the most common mistake with the Pro Grow UFO?
Running it too close or at full power too soon. Start higher and dimmed (if possible), then slowly adjust. Watch plant feedback and avoid changing multiple variables at once.
