Mammoth Lite+ 90 Grow Tent – 90x90x180cm | Reflective & Sturdy

The Mammoth Lite+ 90 is the definitive leap from amateur experiments to professional results, offering you a 90x90x180 cm growing space designed to maximize every lumen of light and every gram of your harvest. This indoor grow tent combines a highly reflective 170D Mylar interior with a robust structure, giving you total control over the environment so your plants can reach their full genetic potential without the hassle of makeshift setups.

Why your current setup is holding you back

Are you still trying to grow in a spare closet, a cardboard box, or an open corner of your room? You probably struggle with light leaks that stress your plants, humidity that ruins your walls, or odors that escape and compromise your discretion. It’s a constant battle to keep the parameters stable, and often, the results just don't match the effort you put in.

Continuing like this is a recipe for frustration. Light leaks can cause your photoperiod plants to revegetate or turn hermaphrodite, ruining months of work. Plus, without proper reflection, you are wasting electricity on light that never hits the buds. It’s inefficient, risky, and honestly, a headache you don’t need.

The Mammoth Lite+ 90 solves all these issues instantly. It creates a sealed, controlled microclimate where you dictate the temperature, humidity, and lighting cycles. No more light leaks, no more wasted energy, and significantly better yields from the very first cycle.

Why this tent improves your indoor game

Switching to a dedicated tent like the Mammoth Lite+ 90 changes everything. Unlike a painted wall or a DIY cabinet, the 170D Mylar lining ensures that 95% of the light is reflected back onto the plants, penetrating deeper into the canopy. This means denser buds on the lower branches, not just the top colas.

Furthermore, the structure is designed for real-world use. It’s not just a fabric box; it’s a system. The 16mm steel poles and reinforced plastic corners provide a rigid frame capable of holding your equipment securely. You can hang your lights and Air Extraction System without worrying about the whole thing collapsing on your precious crop.

Key features you’ll notice from the very first grow

• Optimized Dimensions: At 90x90x180 cm, it provides 0.81 m² of growing surface, the perfect sweet spot for a 400W HPS or a high-efficiency LED.
• High Reflectivity: The 170D Mylar interior maximizes light intensity, boosting photosynthesis and increasing final weight.
• Total Light-Proofing: High-quality zippers and thick fabric prevent light from entering or escaping, protecting your dark cycles.
• Sturdy Frame: 16mm steel poles support up to 20 kg of equipment, enough for your filter, fan, and reflector.
• Smart Ports: Includes a 152mm opening for ventilation ducts and a 76mm port for cables, keeping your setup tidy.
• Easy Maintenance: The material is washable on both sides, so you can keep your grow room sterile and pest-free between cycles.

Who is the Mammoth Lite+ 90 for?

This tent is the ultimate "workhorse" for practical growers. It strikes the perfect balance between size and production capacity.

• The Apartment Grower: Fits perfectly in a bedroom corner or spare room without taking over the entire house.
• The Self-Sufficiency Seeker: Large enough to harvest a supply that lasts months, but small enough to manage solo.
• The Budget-Conscious Pro: You get Mammoth quality engineering without the premium price tag of the heavy-duty industrial lines.

How to integrate it into your routine

Setting up the Mammoth Lite+ 90 is a breeze and requires no tools. Once assembled, pair it with one of our Grow lights—a 300W LED is ideal for managing heat in this volume, or a 400W HPS if you have good extraction. Place a tray at the bottom to catch runoff, hang your carbon filter from the roof bars, and you are ready to roll.

Thanks to the cable port, you can keep all your electrical connections outside the tent for safety. The 152mm vent port is standard, making it compatible with most extractors on the market. It’s designed to make your daily watering and checking routine as smooth as possible.

Frequently Asked Questions

How many plants can I fit in this tent?

In a 90x90cm space, you can comfortably grow 6 to 9 plants in 7-liter pots using the Sea of Green (SOG) method, or 4 large plants in 11-18 liter pots if you prefer to let them grow bigger bushes.

Is it difficult to assemble?

Not at all. The Mammoth Lite+ 90 uses a click-system for the poles. One person can assemble it in about 15-20 minutes without any tools. The instructions are clear and straightforward.

What lighting do you recommend for this size?

For a 90x90cm area, a 300W or 400W LED is the most efficient choice to keep heat down and yields up. If you prefer old-school tech, a 400W HPS works great, but ensure you have a good extractor fan to manage the temperature.

Can I use it for both drying and growing?

Yes! While it's designed for growing, many users buy a second grow tent of this size specifically to use as a drying tent because it's dark, enclosed, and allows for controlled airflow with a small fan.

Personal Experience of Pevgrow’s CEO (Alan)

"I remember my first indoor setups were... let's say, 'creative'. I used wood, plastic sheets, you name it. But the moment I switched to a proper Mammoth tent, the difference was night and day. The Lite+ 90 is what I recommend to friends who want to start growing seriously but don't want to spend a fortune on industrial gear.

What I love about this specific size is that it's manageable. You can reach the plants at the back without breaking your back, and the reflection from the Mylar is surprisingly good for a 'Lite' version. I've run a 315W CMH in one of these and pulled incredible quality. It holds the humidity well and the zippers don't snag, which is usually the first thing to break on cheap tents. If you want reliable homegrown without the hassle, this is a solid choice."
