Complete Kit without Carbon Filter 120x120cm - 1.4m²: Your Turnkey Grow Setup

The complete 120x120cm grow kits without carbon filter are the perfect solution to start an indoor grow on 1.4m² without any hassle. These kits include all essential equipment: grow tent, high-performance lighting system, and adapted ventilation. The 120x120cm format offers a comfortable working space for 4 to 6 plants depending on the technique used.

Why choose a complete 120x120cm kit without a filter?

The main advantage of these kits is the guaranteed compatibility between all components. No more complicated calculations to figure out if your 125mm extractor will work with your tent or if your 240W LED will be enough for 1.4m². Everything is already sized by professionals who know the industry. The 120x120cm surface optimizes available space while maintaining easy access to plants from all sides.

These filter-free kits are particularly suitable for growers who manage odor in other ways (well-ventilated room, direct extraction to the outside) or who plan to add their own filtration system later. The savings on the filter can be reinvested in more powerful lighting or complementary accessories.

The ventilation included in these kits ensures optimal air renewal with flow rates generally between 160 and 250 m3/h depending on the models. This is more than enough to maintain a stable temperature and avoid humidity problems in this area.

How to choose your 120x120cm kit without a filter

The main criterion remains the lighting integrated into the kit. For 1.4m², count on a minimum of 200W in full spectrum LED or 250W in HPS to get decent results. The best kits go up to 320W LED, which allows reaching the recommended 400-500 µmol/m²/s for intensive cultivation.

Also check the quality of the tent: minimum 600D fabric, YKK zippers, and 16mm tube structure for solidity. The actual internal dimensions are important because some tents advertise 120x120 but are actually 115x115cm once assembled.

Regarding ventilation, a 125mm extractor with adjustable flow remains the standard. Some kits also include a circulation fan, essential for homogenizing temperature and humidity. Don't forget to check the length of the ducts provided (generally 3m) and the presence of clamps.

Finally, look at the included accessories: hanging straps, thermometer/hygrometer, timer for lighting. These little extras avoid additional purchases and allow you to start immediately.

Frequently Asked Questions

Is this carbon filter-free kit suitable for my needs, or should I add a filter separately?

That depends entirely on your situation. If your grow space is in a garage, basement, or a well-insulated room with direct extraction to the outside, the filter-free kit is more than sufficient. However, if you are growing in an apartment or if odors could be an issue, you will need to plan for a separate carbon filter. For a 120x120cm setup, a 125mm filter with 300-400 m3/h capacity will do the trick. The advantage of filter-free kits is precisely this flexibility: you can choose exactly the type of filtration that suits you.

What is the ideal distance between the lamp and my plants with this 120x120 cm format?

For a 120x120cm tent, the distance varies depending on the type of lighting. With a 240-320W LED, keep 30-40cm during vegetative growth and lower it to 20-30cm during flowering, depending on plant tolerance. For a 250-400W HPS, count on a minimum of 40-50cm due to the heat generated. The trick is to monitor the temperature at leaf level: if you feel the heat with your hand, it's too close. In this area, you can easily adjust the height using the ratchet straps provided with most kits.

How do I properly install and configure ventilation and air extraction in this tent?

Installation is quite straightforward in a 120x120cm setup. Place the extractor at the top of the tent on the side opposite the fresh air intake to create a diagonal flow. Passive air intake occurs through the bottom sleeves; an intake fan is never needed for this size. Adjust the flow rate to renew the air 40-60 times per hour, which is about 200 m3/h for 1.4m². The circulation fan should be positioned high up to circulate the rising warm air. Remember to keep the extraction ducts as straight as possible to avoid pressure losses.

Can I use this kit for all growth phases, or do I need to change the lighting?

Modern kits with full spectrum LEDs perfectly cover the entire grow from start to finish. LEDs generally include blue (400-500nm) for vegetative growth and red (600-700nm) for flowering, plus white for general photosynthesis. With a good LED of at least 240W, you get decent results in both phases. If the kit includes an HPS, it will be more oriented towards flowering (2100K spectrum), in which case adding an MH or T5 6400K fluorescents for vegetative growth optimizes results. But frankly, a good LED avoids these complications.

What type of bulb is most suitable for this area, and what is the energy cost?

For 1.4m², LED remains the smartest choice in terms of consumption and performance. A 280-320W LED consumes approximately 0.28-0.32 kWh, or €2-2.5 per day at a rate of €0.18/kWh over 12 hours of operation. An equivalent 400W HPS would go up to €3.5/day. Over a 3-4 month grow, the LED savings become significant. In terms of performance, modern LEDs easily reach 2.5-2.8 µmol/J efficiency compared to 1.3-1.5 µmol/J for HPS. Not to mention the reduced heat, which simplifies climate management in this enclosed area.
