RQS 320 W LED Grow Light: High-Performance Full-Spectrum for 90x90 cm Tents

The RQS 320 W LED Grow Light is our high-performance full-spectrum fixture built for 90x90 cm grow tents, delivering 1029 μmol/m²/s PPFD across the canopy with 1260 LED chips and a 60x60 cm panel footprint. It is designed for mid-size indoor spaces where yield density and even coverage both matter.

RQS 320 W LED Grow Light: Full-Spectrum Power for Mid-Size Grows

Part of our new RQS cultivation range, the 320 W LED scales up the performance of our 150 W panel for growers working in larger tents, whether that is our 90x90x200 cm grow tent, a dedicated closet grow, or a multi-plant SCROG setup. The fixture draws 320 W through 1260 full-spectrum LED chips spread across a 60x60 cm panel, producing 1029 μmol/m²/s PPFD at the canopy. That is enough photosynthetic intensity to push heavy flowering across nine plants in 8 L pots or a compact four-plant grow in 18 L containers, without the heat output or electricity bill of a comparable HPS fixture.

Diode Density and Balanced Spectrum Output

1260 LEDs packed into a 60x60 cm panel is a meaningfully higher diode count per square centimetre than most competing fixtures in this wattage class. Density matters because it keeps light sources physically closer together, which flattens hotspots and reduces edge falloff across the 90x90 cm canopy below. The spectrum output pairs blue wavelengths for compact vegetative growth with deeper reds that trigger resin production and cola stacking, so a plant positioned in the corner of the tent finishes at roughly the same trichome density as one directly under the fixture.

What 1029 μmol/m²/s PPFD Means in Practice

Cannabis reaches light saturation around 1500 μmol/m²/s under elevated CO₂ and noticeably lower in unsupplemented air. A 45 cm reading of 1029 μmol/m²/s sits comfortably inside the productive band for a sealed tent on ambient CO₂, giving plants enough intensity to push dense flowering without tipping into light-stress territory.

The test data we hold for the 320 W gives growers a practical dimmer through mounting height: 1029 μmol/m²/s at 45 cm, with centre readings peaking above 1400 μmol/m²/s at 30 cm, and easing to a 553 μmol/m²/s canopy average at 60 cm. Raise the fixture for seedlings and clones, sit it at 45 cm through veg and stretch, and drop it closer once the canopy has committed to bloom.

Coverage and Pot Capacity in a 90x90 cm Tent

The 320 W is sized for our 90x90x200 cm grow tent. Run it over nine plants in 8 L fabric pots for a high-count perpetual cycle, five to nine 11 L pots for a balanced yield-per-plant grow, or four 18 L containers when you want larger individual plants with heavier main colas. Corner coverage stays close to centre coverage across all three configurations.
