With 1.44 m² of floor area and 2.88 m³ of usable volume, it comfortably hosts 4 full-size plants in flowering, a dozen cuttings or a few mother plants under a horticultural LED lamp.

Every photon emitted by your full-spectrum LED grow light is bounced back onto the canopy by the highly reflective Mylar liner. The payoff: better spectrum utilisation, wider leaves, denser flowers and uniform growth from top to bottom of the plant.
The 420D nylon outer shell blocks 100% of stray light. No leakage disrupts the 12/12 flowering photoperiod, and when the tent is paired with a carbon-filter extraction kit, no odour escapes either.
Steel tubes and injected connectors stay rigid cycle after cycle. The crossbars comfortably hold a full LED fixture, an inline fan, a carbon filter and circulation fans — all your horticultural gear sits safely above the canopy.
Top and bottom duct sleeves, light-proof cable ports, removable harvest floor and an inspection window: the full toolkit to manage air, water, power and checks without ever breaking the light seal.
Assembled in under 20 minutes using clip-on connectors. Delivered in a sturdy carry bag, the Probox BASIC packs down, moves and redeploys with ease — ideal to test a second grow room or relocate your indoor setup.
Hand-picked by the BloomLED team: the best quality-per-square-meter under €110 in the 120 × 120 class. Designed for indoor growers and shipped fast from our French warehouse by horticultural LED experts with 10+ years in the game.
In flower, the 1.44 m² footprint hosts 4 full-size plants in 15–25 L pots, or 9 plants in a SCROG with a horizontal net. In vegetative or cloning phase, you can push to 16 young plants, and even more on a dedicated cloning tray.
What LED grow light wattage should I install?For a strong flowering cycle in a 120 × 120, plan 400–450 real watts of full-spectrum horticultural LED (≈ 28–32 mol/m²/day DLI). In veg or cloning, 200–250 W is more than enough. The BloomLED team can recommend a compatible 4×4 fixture for your goals.
Is the Probox BASIC compatible with a carbon filter and inline fan?Yes. The hanging bars handle a full extraction kit: carbon filter + inline fan in 150 or 200 mm diameter are ideal for 2.88 m³. The top and bottom duct sleeves accept those diameters and preserve the light-seal.
How do I assemble the Garden HighPro grow tent?Assembly is tool-free and takes under 20 minutes: clip the 4 vertical poles into the floor frame, add the crossbars, slide in the canvas and close the reinforced zippers. An illustrated manual is included and BloomLED's support team is on hand for any question.
