Dark Room Grow Tent 150x150x217cm – Secret Jardin Professional

The Dark Room Grow Tent 150x150x217cm by Secret Jardin is the professional infrastructure you need to transform any room into a high-performance biological laboratory, providing you with 2.25 m² of completely controlled cultivation space. This tent defines the standard for durability and efficiency, allowing you to isolate your plants from the outside world to maximize their genetic potential without external interference.

Is your grow room a chaotic mess of cables and light leaks?

Let's be real: trying to grow indoors without a proper tent is often a disaster waiting to happen. You end up with accessories scattered all over the room, makeshift reflective plastic peeling off the walls, and a constant battle against light leaks that can stress your plants. Not to mention the smell that permeates the whole house because you can't create negative pressure effectively.

This lack of organization doesn't just look bad; it steals your time and kills your yields. Every time you have to move a fan that's in the way or worry about light interrupting the dark cycle, you are adding stress to yourself and your crop. A disorganized space leads to mistakes, pests, and a subpar harvest that doesn't reflect the effort you put in.

The Dark Room Grow Tent 150x150x217cm is the definitive solution to organize your space and simplify your setup. By centralizing your entire operation inside this sturdy, light-proof fortress, you regain control over the environment, keeping everything from humidity to odors perfectly managed within a professional enclosure.

How your space changes once you add it

Visually, the change is drastic. You go from having a room that looks like a messy workshop to a sleek, professional setup. The Dark Room acts as a self-contained ecosystem. Once zipped up, it’s just a clean, silver unit that keeps the bright grow lights and strong aromas contained. It allows you to reclaim the rest of the room for other uses without tripping over ballast cables or ducting.

Practically, the flow of your cultivation improves immediately. Because it is designed specifically for Grow tents, the ports for extraction and cabling are exactly where you need them. You stop improvising and start growing with precision, knowing that your climate parameters will remain stable thanks to the high-quality sealing.

What you can organise with this product

This tent is a beast when it comes to capacity. With 2.25 square meters of floor space and, crucially, 2.17 meters of height, you can fit a serious setup inside without cramping your plants.

• Lighting systems: Perfect for a 600w Grow light LED or even a 1000W HPS, with enough headroom to avoid heat stress.
• Ventilation: Dedicated ports for Ventilation tubes up to 280mm, allowing for powerful air exchange.
• Filtration: Heavy carbon filters can be hung easily thanks to the 75kg load capacity.
• Hydroponics: Spacious enough for large Grow Trays or complex DWC systems.
• Accessories: Fans, thermo-hygrometers, and CO2 bags all have their place.

Steps to build your organised set-up

1. Clear the area: Make sure you have a 160x160cm footprint available to work comfortably.
2. Assemble the frame: Connect the robust 25mm stainless steel poles. They click together easily—no tools needed.
3. Skin the frame: Unfold the Mylar 400D canvas and wrap it around the structure, zipping it up to ensure a tight fit.
4. Install equipment: Hang your lights and filter from the roof bars before putting plants in.
5. Route your ducting: Use the adjustable socks to run your extraction and cables, tightening them to prevent light leaks.
6. Final check: Turn on the lights and check for any pinholes (though with Secret Jardin, these are rare) and ensure negative pressure is achieved.

Advantages and benefits of having everything in its place

• Total Light Proofing: The 400D Mylar offers 95% reflection and blocks external light, preventing hermaphroditism caused by light stress.
• Superior Durability: The 25mm poles are significantly stronger than standard tents, meaning no sagging under the weight of heavy equipment.
• Extra Height: At 2.17m tall, you have more vertical room for Sativa strains or to keep hot lights further away from the canopy.
• Easy Maintenance: The water tray liner is removable and washable, making cleaning up spills or soil runoff a breeze.
• Climate Stability: A sealed environment makes it much easier to maintain constant temperature and humidity levels.

Frequently Asked Questions

How many plants fit in this 150x150 tent?

You can comfortably fit about 9 to 16 plants in 11-liter pots if you are doing a standard grow. If you are doing a Sea of Green (SOG), you could fit up to 25 smaller plants. If you prefer large SCROG monsters, 4 large plants will fill the screen perfectly.

Is the structure strong enough for heavy LEDs and filters?

Absolutely. The Dark Room series uses 25mm diameter stainless steel tubes, which is thicker than the industry standard. It supports up to 75kg of equipment, so you can hang heavy carbon filters and premium LED fixtures without worry.

Does it come with the ventilation equipment?

No, the tent is the structure itself. You will need to purchase your extractor, filter, and lighting separately, which allows you to customize the equipment exactly to your needs.

Is it difficult to assemble alone?

It is designed to be assembled by one person, but due to the 2.17m height, having a friend help you pull the canvas over the top of the frame makes the process much faster and easier. It usually takes about 15-20 minutes.

Personal Experience of Pevgrow’s CEO (Alan)

I've set up dozens of tents over the years, and the jump in quality when you move to the Dark Room series is noticeable immediately. The zipper action is smooth—which sounds like a small detail until you're opening it twice a day for months—and the light leaks are non-existent. But for me, the real game-changer with this 150x150x217 model is that extra vertical space.

Those extra centimeters of height compared to standard 2m tents save you a lot of headaches. It allows you to mount your filter and extractor inside the tent at the very top without them eating into your lighting space. This means you can let your plants grow taller or keep your lights at a safer distance during the peak of flowering, which directly translates to better bud quality without heat stress.
