🔆 Ultra-reflective 600D Diamond Mylar
The 600D Diamond interior lining bounces back more than 95% of the light spectrum onto your plants. Every watt of your LED or HPS fixture is exploited to the maximum, with no dead zones or shadow areas. The Diamond pattern diffuses the light evenly for consistent PAR/PPFD coverage across the entire canopy.
💪 Reinforced Ø 25 mm tube structure
Pre-painted steel frame with 25 mm diameter — stiffer than the classic 22 mm G-PRO range. Corners are cast in heavy metal to absorb the load of roof bars (carbon filters, lamps, fans) without deformation, even after several cultivation cycles.
🌬️ Pro multi-port ventilation
Dedicated 254 mm and 304 mm outlets for exhaust and intake ducting, plus Ø 204 mm cooltube passes and Ø 102 mm cable ports. Every opening is fitted with an adjustable fabric sleeve with double drawstring, guaranteeing perfect light-tight and odour-tight sealing.
🌱 300×150 rectangular footprint
The rectangular shape optimises space in a garage, a basement or against a wall up to 2.20 m high. Ideal to align two separate cultivation zones (mother/clones + flowering) or to install multiple lamps side-by-side without shadow interference.
🔧 Fast assembly, fully demountable
Illustrated manual, click-together frame requiring no tools, single-pass fabric cover: count 30 to 45 minutes for your first solo assembly. The box folds completely flat for off-season storage or moving.
🛡️ Light- and odour-tight sealing
Heavy-duty double zip on the doors, drawstring sleeves, waterproof drip tray and observation window with blackout flap: no light leaks (essential to respect the 12/12 flowering cycle) and excellent odour containment in synergy with a carbon filter.
What LED power should I install in a G-PRO+ Diamond 300×150?
For 4.5 m² of floor area, expect 600 to 900 W actual LED (full spectrum), spread over 2 to 3 quantum-board modules or LED bars. With HPS, two 600 W lamps with adjacent reflectors work very well thanks to the 2.20 m height. BloomLED recommends aiming for 30-40 W/m² actual in veg and 40-50 W/m² in flowering for optimal PPFD.
Which extractor fan is compatible with this grow tent?For 4.5 m², target an extractor of 360 to 500 m³/h with a Ø 150 mm or Ø 200 mm outlet. The 254/304 mm openings on the tent allow you to use insulated 200 mm ducting without flow loss. Always pair it with a carbon filter of equivalent capacity for odour neutralisation during flowering.
What is the difference between G-PRO and G-PRO+?The G-PRO+ range uses Ø 25 mm steel tubes (versus 22 mm for the classic G-PRO), delivering superior rigidity and increased load capacity on the roof bars (50 kg per bar). The 600D Diamond Mylar lining is identical, as are the watertight finishings. Recommended whenever you install heavy equipment: carbon filters ≥ 250 m³/h, HPS lamps, multiple fans.
Can this tent be installed in an apartment?Yes, provided you have a minimum space of 3.10 m long × 1.60 m wide × 2.30 m high (including circulation around it). The 300×150 rectangular shape fits perfectly along a wall. Consider isolating the floor (anti-vibration mat under fans) and respecting a silent 12/12 cycle with a silent-box extractor.
