Dark Room II Grow Tent 120x120x200 cm – Secret Jardin Premium Indoor Box

The Dark Room II Grow Tent 120x120x200 cm by Secret Jardin is the definitive solution for turning any corner of your house into a professional grow room, guaranteeing you a controlled environment and explosive yields without the need for construction work.

Why growing without a tent is a waste of time

Trying to set up an indoor crop without a specialized space often turns into a nightmare of improvisation. You waste hours covering windows with plastic to stop light leaks, drilling holes in walls that you'll have to repair later, and struggling to control humidity and temperature in an open room. Instead of enjoying your hobby, you become a slave to constant adjustments and precarious fixes.

This lack of control leads to mediocre results: plants that stress and revegetate due to light pollution, odors that escape and bother the neighbors, and equipment that isn't securely fastened. In the end, you spend more money on electricity for a harvest that doesn't meet your expectations, leaving you frustrated and with a lot of cleaning to do.

The Dark Room II solves all this instantly by creating a hermetic, safe, and optimized ecosystem. It is designed so you can assemble a professional laboratory in minutes, isolating your plants from the outside world and allowing you to control every parameter (light, air, humidity) with absolute precision and minimum effort.

How this grow tent saves you time and effort

Forget about DIY disasters. This tent is designed to make your life easier from minute one. Its structure comes with pre-equipped socks for your Air Extraction System and wiring, meaning you don't have to cut or adapt anything. You simply pass the tubes through the adjustable sleeves, tighten them, and you have a sealed environment.

Maintenance becomes ridiculous. Thanks to its waterproof floor and easy-to-clean materials, any spill or soil debris is resolved with a damp cloth in seconds. You won't have to scrub carpets or worry about ruining the parquet floor of your apartment. Everything stays inside the tent.

Simple steps to use it without wasting a minute

Getting your indoor grow running has never been this fast. Follow this flow to optimize your time:

1. Unfold and click: Assemble the metal frame and slide the canvas over it. It requires no tools and takes less than 15 minutes.
2. Hang your gear: Use the reinforced bars to hang your Grow lights and carbon filter. The structure holds the weight without flinching.
3. Install ventilation: Pass the ducts through the adjustable socks and close them tight to prevent light leaks.
4. Fill it up: Place your pots inside (I recommend using Grow Trays to keep the floor pristine) and close the zipper. You are ready to grow.

Advantages and benefits in your daily routine

• Total Light Optimization: The Mylar 210D lining reflects 95% of the light. This means your plants grow faster and you get more grams per watt without doing anything extra.
• Zero Stress over Odors: Its hermetic seal, combined with a good filter, ensures that the smell of your crop doesn't leave the cabinet. Total discretion for you.
• Sturdy Structure: You can hang heavy equipment without fear of it collapsing. This gives you peace of mind knowing your plants are safe while you're at work.
• Thermal Isolation: Helps maintain a stable microclimate, protecting your plants from sudden temperature changes in your home.
• Easy Access: The front door allows you to water and inspect your plants comfortably without having to dismantle anything.

Tips to integrate it into your habits without friction

To make the experience even smoother, place the tent in a room with a window nearby for easy air renewal. Since it measures 120x120 cm, it fits perfectly in a spare bedroom or a large garage corner. Use a timer for your lights and you practically automate the most critical part of the process.

If you want to maximize cleanliness, keep a small box with your tools (scissors, pH meter) right next to the tent. This way, when you have 10 minutes of free time, you can open the zipper, do your maintenance, and close it up without running around the house looking for gear.

Frequently Asked Questions

How many plants fit in this 1.20m tent?

It depends on the pot size, but comfortably you can fit about 9 plants in 11-liter pots or up to 12 if you use smaller pots (7L) and do a SOG (Sea of Green). It's the standard size to get around 500g per harvest.

Is it difficult to assemble if I'm alone?

Not at all. The Secret Jardin system is very intuitive. One person can assemble it in about 15-20 minutes. The tubes click together and the canvas fits like a glove.

Does light escape through the zippers?

No, the Dark Room II is designed to be light-proof. The zippers are reinforced and have flaps to ensure that when it's closed, it's pitch black inside and no light leaks out to disturb your sleep.

Personal Experience of Pevgrow’s CEO (Alan)

For me, the 1.20x1.20 meter size is the "golden standard" of indoor growing. When I don't have time to experiment with micro-grows or manage a massive room, I set up a Dark Room II. It's the perfect balance: big enough to get a harvest that lasts me months, but small enough to manage in a few minutes a day.

What I appreciate most about this specific model is the quality of the zippers and corners. I've had cheaper tents where the zipper breaks in the middle of flowering, and it's a disaster. With Secret Jardin, I know I can open and close it three times a day and it will hold up perfectly. My tip: keep the vents open at the bottom for passive intake and let the extractor do the work at the top; the airflow is perfect that way.
