Mammoth Lite+ 240L Grow Tent – 240x120x200cm · Large & Affordable Indoor Box

The Mammoth Lite+ 240L is the definitive answer for growers who want a massive 2.88m² cultivation area without the massive price tag, offering a robust structure and high reflectivity to maximize every lumen. It is a large-format indoor grow tent designed to strip away the unnecessary and focus purely on performance, giving you a professional environment that is easy to assemble and even easier to maintain.

Let’s be honest: how many times have you found yourself tripping over cables, dodging ducting, or trying to manage three different timers because you’re running multiple small setups or a DIY room? It’s the classic grower’s trap—accumulating gear to solve space issues until your grow room looks more like a storage unit than a garden.

This chaos doesn't just look bad; it kills your efficiency. You end up checking pH in one corner, adjusting humidity in another, and realizing you’ve neglected the plants in the back because they are hard to reach. The mental load of managing a cluttered space takes the fun out of growing and often leads to mistakes that cost you grams at harvest time.

The solution is consolidation. By switching to the Mammoth Lite+ 240L, you replace the clutter with a single, streamlined ecosystem. It allows you to centralize your climate control, lighting, and irrigation into one efficient block, reducing the gear you need while increasing the canopy space you actually want.

Less clutter, more functionality with this 240x120 tent

Think of the Mammoth Lite+ 240L as the "master reset" for your indoor garden. Instead of running two separate 1.2m tents—which requires double the extractors, double the filters, and double the ducting—this unit gives you the same footprint (240x120cm) in a continuous space. This means you can often run a single, more powerful Air Extraction System rather than maintaining two weaker ones.

The design is intentionally pragmatic. It features a Mylar Silver 170D interior with 85% reflectivity. While it doesn't have the heavy-duty thickness of the Pro series, it provides exactly what the practical grower needs: excellent light diffusion and a light-tight environment. The 16mm tubes are lightweight for easy assembly but rigid enough to hold your lights and filters securely. It’s about stripping back the "nice-to-haves" to give you the "must-haves" at an unbeatable price.

What you can simplify once you have it

Once you install this tent, you will notice your equipment list shrinking while your potential yield grows. Here is what you can stop worrying about:

• Redundant Climate Control: Use one humidifier and one heater for the whole crop instead of buying multiples for different small spaces.
• Cable Spaghetti: With specific cable ports (3 x 76mm), you can route everything cleanly, removing trip hazards.
• Complex Ventilation: A single intake and extraction setup covers the entire 5.76 m³ volume efficiently.
• Access Issues: The large front doors give you full access to the crop without having to move equipment around.
• Wasted Light: The rectangular shape is perfect for covering with two 600W HPS or two modern LED fixtures, creating an even canopy with no dark corners.

How to build a more minimalist set-up with this product

Ready to clean up your act? Follow these steps to optimize your grow room with the Mammoth Lite+:

1. Clear the Deck: Remove your old, smaller tents or dismantle that makeshift DIY frame.
2. Assemble the Frame: The 16mm poles click together fast. You don't need tools, just your hands.
3. Skin the Tent: Slide the fabric over. It’s lightweight, so you can do this solo, though a friend helps.
4. Centralize Lighting: Hang your Grow lights. For this size, two light sources are ideal to cover the 240cm length.
5. Streamline Airflow: Install your filter and fan at the top. Use the 254mm extraction port for a high-flow setup.
6. Organize the Floor: Place your pots or a large tray. You now have a clean, enclosed rectangle to work in.

Frequently Asked Questions

Is the 170D fabric thick enough to prevent light leaks?

Yes, for most home environments, the 170D material is sufficient. It is lighter than the Pro versions but is designed to be light-tight when zippers are closed properly. If the room outside is pitch black during the dark cycle, you are 100% safe.

What is the best lighting configuration for this tent?

This 240x120cm footprint is the "double square" standard. It works perfectly with two 600W HPS lights or, for better efficiency and heat management, two 480W or 600W LED fixtures. This ensures even coverage from wall to wall.

Can I use this for hydroponics?

Absolutely. The floor space is ideal for large Grow tents setups like NFT tables or multiple DWC buckets. Just ensure you protect the floor with a tray or liner to catch any spills.

How many plants fit in the Mammoth Lite+ 240L?

It depends on your style. You could do 24-30 plants in smaller pots (SOG style) or 8-10 massive plants in large pots (SCROG style). The height of 200cm gives you plenty of vertical room for sativas.

Personal Experience of Pevgrow’s CEO (Alan)

I remember when I started scaling up, I thought I needed the most expensive, heavy-duty bunker I could find. But the truth is, unless you are hanging industrial AC units from the ceiling, the Mammoth Lite+ series is the smartest play. I switched a setup from two smaller tents to one of these 240L units, and the difference in workflow was immediate.

Suddenly, I wasn't mixing two batches of nutrients or checking two different hygrometers. I had one ecosystem. The 16mm poles are surprisingly rigid once the structure is locked in, and the money I saved on the tent went straight into better genetics and a high-end LED. If you want to simplify your life and maximize your harvest, this is the gear to do it.
