Grow Pack Base Dark Street 120 - 400 Watt large-format budget indoor grow kit

What separates this Base kit from every other in the range is its scale and airflow design. The Grow Pack Base Dark Street 120 builds on a Secret Jardin Dark Street R4.0 tent at 120x120x198 cm and includes two inline duct fans rather than one, enabling active intake and exhaust for superior climate control across the 2.85 m³ tent volume.

Dual-fan airflow configuration

The kit ships with a Ø150 mm duct fan rated at 300 m³/h and a Ø125 mm duct fan rated at 185 m³/h. The recommended setup positions the larger fan as the exhaust at tent ceiling level, pulling warm air upward and out. The smaller fan serves as an active intake at a lower entry point, pushing fresh air into the growing space. This dual-fan approach creates positive airflow patterns that single-fan passive-intake setups cannot achieve.

Combined airflow capacity of 485 m³/h across both fans ensures rapid air exchange even at peak lamp temperatures.
The Secret Jardin Monkey Fan adds canopy-level oscillation, reducing thermal stratification and strengthening plant stems.
A timer manages photoperiod automation while the thermo-hygrometer with probe delivers real-time temperature and humidity data.
Nine square 3.4-litre pots and three connection cables complete the package.

400W lighting: performance without thermal overload

The Superplant Duo 400W ballast supports both HPS and MH bulb types, shipping with a Philips Greenpower 400W HPS lamp and mirror reflector. At 400W over 1.44 m², the system delivers approximately 278 W/m², producing less heat than a 600W configuration while still providing meaningful light intensity for flowering. The Duo ballast accepts a 400W MH bulb for vegetative phases, adding spectral flexibility without a hardware change.

Why the Dark Street tent at this tier?

At 120x120 cm, the heavier frame and thicker fabric of the Dark Street series become practically necessary. The Hydro Shoot line is not available in this size, and the Dark Street's robust construction handles the weight of a 400W lighting system plus dual fans without stress on the frame. Growers wanting to step up to 600W with professional filtration should evaluate the Grow Pack Deluxe Dark Street 120. A replacement Philips Greenpower 400W bulb is available separately.

Ships in one discreet package with fast delivery across Belgium. The largest Base-tier kit available, built for Belgian growers who want maximum growing space on a streamlined budget.

Can a carbon filter be added to the Grow Pack Base Dark Street 120 later?

The Ø150 mm exhaust fan can be connected to a separately purchased carbon filter using compatible ducting and a hose clamp. A filter rated at 300 m³/h or higher would match the fan's capacity without creating an airflow bottleneck.
