With a 200 × 200 cm footprint and 220 cm of vertical clearance, you gain the critical headroom that makes everything easier: you can hang a high-power LED at the right distance from the canopy, mount an inline fan high up, and walk around large pots without bumping into the frame.
The interior Mylar Diamond 600D reflects more than 95% of incident light with a diamond-pattern dispersion. The output of your horticultural LED is redirected to every leaf instead of being wasted, dramatically improving PPFD penetration to the lower canopy.
The 25 mm steel poles and metal corners handle heavy payloads: large-area LEDs, 200 mm carbon filters, high-flow extractors, oscillating fans. Where entry-level tents flex, the G-PRO+ holds its shape cycle after cycle.
160 and 200 mm sleeves distributed across all four corners: install your inline fan, your passive intake and your carbon filter exactly where it makes sense for your room layout. Perfect for a balanced air-flow design.
Anti-leak baffles, double zips and a 600D opaque polyester shell: no stray light escapes during the dark cycle, and no outside light leaks in during flowering. Your photoperiod is preserved without compromise.
Clip-based assembly and pre-marked poles make a two-person setup feasible in under an hour. The included watertight spill tray protects your floor from any irrigation overflow.
BloomLED tip: the G-PRO+ Diamond 200x200x220 hits its sweet spot with a 600 to 800 W full-spectrum horticultural LED, a 200 mm inline fan with carbon filter, and 4 to 9 pots of 25–30 L in organic soil. The perfect setup for a passionate grower who wants serial harvests without oversizing the gear.
For a 4 m² footprint, plan for 600 to 800 W of high-efficacy full-spectrum horticultural LED (≈ 150 to 200 W/m²) for optimal flowering. If you want to push yield, up to 1000 W is doable as long as ventilation keeps up.
Which inline fan should I pair with this tent?With 8.8 m³ of usable volume, aim for an 800 to 1200 m³/h extractor to renew the air every 1 to 2 minutes once you factor in carbon-filter pressure loss. A 200 mm model with speed controller is the safest bet.
How many plants can I grow inside?It depends on your method: 4 to 6 large plants in 25–30 L pots, 9 plants Sea-Of-Green-style in 11 L pots, or a compact hydroponic system. The 220 cm height also leaves plenty of room for trellising and LST without compromise.
Does the frame really hold a heavy LED + filter setup?Yes. The 25 mm steel poles and upper bars carry roughly 50 kg evenly distributed: more than enough for an 800 W LED (8–12 kg), a 200 mm carbon filter (12–15 kg) and an inline fan. Just spread the weight rather than hanging everything from a single point.
What's the difference vs the standard G-PRO Diamond?The G-PRO+ uses 25 mm poles (vs 22 mm on the standard G-PRO), reinforced metal corners and thicker outer fabric. It is the right choice for long-cycle gardens or installations loaded with heavy gear.
