Dark Propagator 90cm Cutting Grow Box – Secret Jardin DP90

The Dark Propagator 90cm Cutting Grow Box is the professional propagation station designed by Secret Jardin to turn your cloning process into a success rate machine. This compact tent provides the perfect microclimate for seedlings, cuttings, and mother plants, ensuring vigorous root development and total light control in a 90x60x98 cm space.

Why cheap propagation setups are costing you money

When you try to root your precious genetics in makeshift cardboard boxes or low-quality tents with light leaks, you are gambling with your harvest. These cheap alternatives often fail to maintain stable humidity and temperature, leading to weak roots, yellowing leaves, and a high mortality rate for your cuttings. You end up with inconsistent growth that delays your entire cycle.

Think about the frustration of cutting 50 clones only to have half of them die or stunt because the environment wasn't right. That is not just wasted time; it is wasted electricity, nutrients, and potential yield. Every day your clones struggle is a day added to your veg time, costing you money and delaying the moment you get to enjoy your flowers. It feels like throwing your hard work into the trash.

The Dark Propagator 90 (DP90) solves this by offering a laboratory-grade environment specifically engineered for the delicate early stages of plant life. It balances professional durability with high-performance materials, ensuring that your cloning success rate hits near 100%. It earns its price by delivering healthy, rooted plants ready to explode into growth, cycle after cycle.

Your secret weapon for a perpetual harvest

Integrating the DP90 into your workflow changes the game completely. Instead of waiting for your main tent to free up to start seeds or clones, you have a dedicated nursery running 24/7. This allows you to create a perpetual harvest system: while your big plants are flowering, your next generation is already rooting and vegging in the DP90.

This tent translates into real value because it minimizes failures. The highly reflective Mylar lining ensures that even low-wattage grow lights are distributed evenly, preventing stretching and weak stems. You get robust, stocky starts that handle transplanting stress much better, saving you weeks of recovery time.

Format, lifespan and efficiency

Secret Jardin is known for quality, and the DP90 is built to withstand the high humidity required for propagation without rusting or degrading.

• Compact Dimensions: At 90x60x98 cm, it fits easily in closets, corners, or on top of other sturdy cabinets.
• Versatile Shelving: It includes a grid shelf, allowing you to double your capacity or remove it to house a larger mother plant.
• High Reflectivity: Lined with Mylar M210, offering 95% light reflection to maximize lamp efficiency.
• Sturdy Frame: Built with 16mm steel poles (Q195 steel) that can support up to 10kg per shelf.
• Lightproof: The fabric is fully opaque, preventing outside light from messing with your photoperiods.
• Easy Maintenance: The water tray liner is removable and waterproof, making cleanup of spills or runoff effortless.

Advantages and benefits in terms of quality–price ratio

Investing in a specific tent for propagation might seem like an extra cost, but the DP90 pays for itself quickly through efficiency.

• Optimized Space: Because of the shelving system, you can fit up to 150 cuttings in less than 1 square meter, maximizing your production per watt.
• Energy Savings: The high reflectivity means you need less powerful lights to get the same growth, lowering your electricity bill.
• Durability: Unlike cheap plastic domes that crack, the DP90's fabric and zippers are designed for years of daily use.
• Climate Control: The integrated socks for extraction and cables allow you to dial in the perfect environment, reducing the risk of mold and pests.
• Stress Reduction: Knowing your genetics are safe in a dedicated space gives you peace of mind and allows you to focus on your flowering plants.

Tricks to get the most out of it without overspending

To maximize the profitability of your DP90, pair it with low-consumption LED bars or CFL bulbs. Since cuttings don't need intense light, you don't need to spend a fortune on electricity. Use the shelf to separate strains or stages of growth: keep fresh cuts on top where it's warmer, and rooted teens on the bottom.

• Use a timer to maintain an 18/6 light cycle to save 6 hours of electricity daily while keeping plants in veg.
• Place a small heating mat under the tray if you are in a cold room; warm roots grow faster.
• Don't oversize your extraction fan; a small inline fan is enough for this volume, saving on equipment costs.

Frequently Asked Questions

Yes! If you remove the middle shelf, the 98cm height is sufficient to keep a bonsai-style mother plant healthy and productive for taking clones.

What lighting do you recommend for this tent?

For this size, two 26W LED bars or a 110W CFL fixture are perfect. You want cool white light (6500K) for vegetative growth without generating excess heat.

Is it compatible with standard extraction systems?

Yes, it comes with ducting flanges and cable socks designed to fit standard small grow tents ventilation equipment.

Personal Experience of Pevgrow’s CEO (Alan)

I've always said that the secret to a great harvest starts with a healthy root system. I use the DP90 personally to keep my favorite genetics alive. For the price, the build quality is unbeatable compared to generic knock-offs. The zippers don't snag, and the light leaks are non-existent.

My top tip: Use the shelf. I keep my seedlings on the top rack and a small mother plant on the bottom right (removing half the shelf). It’s like having a biological backup drive for your garden. If you are serious about growing, this little tent is one of the best investments you can make to professionalize your setup.
