Cultibox Open Grow Tent 120x120x200cm – Total Access & Diamond Reflection

The Cultibox Open 120x120x200 cm is a premium indoor grow tent designed with a revolutionary total opening system that gives you absolute access to every corner of your crop without breaking a sweat.

Managing an indoor grow in a standard tent usually means wrestling with zippers and contorting your body just to reach the plants in the back corners.

There is nothing more frustrating than having to pull out half of your heavy, flowering pots just to water or prune the ones hiding in the back, risking broken branches, stressing your girls, and wasting your precious time every single day.

The Cultibox Open completely eliminates this nightmare by allowing you to unzip the front and both sides simultaneously, plus a handy rear window, turning your daily maintenance into a smooth, effortless, and highly productive routine.

Before setting up your Cultibox Open grow tent

Preparing your space is the first step to indoor glory. You need a room with stable temperatures and enough clearance to take full advantage of the side and rear openings. Think about your layout: since you can access the plants from almost any angle, you can place this tent in a corner or right in the middle of your room, depending on your ventilation setup.

• Measure your room to ensure you have at least a few inches of clearance around the tent for easy unzipping.
• Plan your Grow lights setup beforehand; a 600W HPS or a high-quality LED fixture fits perfectly in this 1.2x1.2m footprint.
• Lay out your irrigation tubing before bringing in the pots, utilizing the tent's special side openings.
• Keep the floor clean and use a protective mat underneath to prevent any accidental water damage to your room.

During your indoor cultivation cycle

Once your girls are inside and the lights are blazing, the magic of the Diamond reflective interior truly shines. This premium mylar bounces light from every angle, ensuring even the lower buds get the energy they need to swell up. You will notice how the adjustable air vents allow you to dial in the perfect negative pressure, keeping odors contained and fresh air flowing.

When it's time to water, train, or defoliate, you simply unzip the main door which folds back the sides, giving you a panoramic view of your canopy. No more blind spots. If you need to check a sneaky plant in the far back, just pop open the rear window. It is a game-changer for maintaining an even canopy and spotting pests or nutrient deficiencies before they become a real headache.

After the harvest: results and maintenance

After chopping down those massive, sticky colas, you will appreciate how easy it is to clean this tent. The wide-open access lets you sweep up dead leaves and wipe down the Diamond mylar walls in minutes, leaving it spotless for the next run.

Maintenance is minimal. Just wipe the reflective interior with a damp cloth and a mild, plant-safe cleaner to keep the reflection at 100%. Check the zippers occasionally and keep them free of dirt or salt buildups from your nutrients, and this tent will serve you for years.

Short- and long-term advantages and benefits

• Total opening system: You can open the front and both sides simultaneously, which means you save time and avoid damaging plants during daily maintenance.
• Diamond reflective interior: It maximizes light distribution and minimizes hot spots, which translates into heavier, denser yields across your entire canopy.
• Rear access window: You can easily reach the plants in the back row, giving you peace of mind and better control over your crop's health.
• Adjustable air vents: Because it features multiple intake and exhaust ports, you can easily install your Air Extraction System for perfect climate control.
• Special irrigation openings: It includes dedicated ports for tubing, allowing you to set up automated watering systems without leaving zippers open or leaking light.
• Sturdy 120x120x200 cm frame: It provides a massive 1.44m2 of growing space with enough height for tall sativas, meaning you can grow bigger plants and harvest more weed.

Personal Experience of Pevgrow’s CEO (Alan)

When I first tested the Cultibox Open, I was honestly blown away by how much it changed my daily routine. Before this tent, I dreaded watering the plants in the back corners of my 1.2x1.2 setups. I used to pull out the front row just to reach the back, which was a massive waste of time. Now, I just unzip the whole front and sides, pull up a stool, and comfortably tend to every single plant like I'm working at a Grow Table.

My top trick with this tent is to use the rear window for a dedicated oscillating fan. It keeps the air moving perfectly through the canopy without getting in the way of the main doors. After the harvest, the cleanup is a breeze because I can literally step inside without tripping over the bottom frame. If you want to save your back and your sanity, this is the tent you need.
