Grow Box Dark Propagator DP120 (120x60x190 cm) – Secret Jardin

The Dark Propagator DP120 by Secret Jardin is the ultimate propagation station designed to turn the most critical phase of cultivation into a stress-free, high-success process. This professional grow tent (120x60x190 cm) allows you to create a completely isolated and controlled environment, specifically optimized to maximize the rooting of your cuttings, the germination of your seeds, or the maintenance of your mother plants with absolute precision.

Why you are limiting your potential without a dedicated space

Problem: Many growers try to root their clones or keep seedlings in a corner of their main tent, on a windowsill, or in makeshift cardboard boxes. This lack of a dedicated environment leads to unstable humidity, light leaks that stress flowering plants nearby, and a disorganized setup that makes it impossible to scale your production.

Agitation: The cost of this "improvisation" is high: yellowing leaves, low rooting rates, and the constant risk of pests wiping out your next generation before it even starts. Plus, mixing vegetative and flowering photoperiods in the same room is a recipe for disaster, often resulting in revegetation or hermaphroditism in your main crop. You are wasting time, money, and valuable genetics.

Solution: The Dark Propagator DP120 solves this instantly by providing a self-contained ecosystem. It is a versatile, multi-layer fortress that fits anywhere. Whether you need to stack hundreds of clones or keep a large mother plant safe, this tent adapts to your needs, ensuring your cloning success rate skyrockets.

Use Case 1: The High-Volume Cloning Factory

If you are serious about production, the DP120 is your best ally. Thanks to its height of 190 cm and the ability to install shelving (grid shelves), you can create up to 3 or 4 independent propagation levels. This turns a small footprint of floor space into a massive production line capable of holding hundreds of Jiffy pellets or rockwool cubes simultaneously.

In this scenario, you can use low-consumption LED strips or CFL tubes on each level. The Mylar 190T fabric ensures that every lumen is reflected back to the plants, preventing stretching. It is the perfect setup for a "Sea of Green" (SOG) preparation, ensuring you always have healthy transplants ready the moment your flowering tent empties.

Use Case 2: The Mother Plant Sanctuary

Maybe you aren't rooting 500 clones, but you have a special phenotype you need to preserve. By removing the intermediate shelves, the DP120 transforms into a spacious vegetative chamber. Its 120x60 cm base and 190 cm height provide ample room for 1 or 2 large mother plants to grow comfortably without touching the lights.

This setup allows you to keep your genetics in a permanent vegetative state (18/6 cycle) completely isolated from your flowering room. You can equip it with slightly more powerful grow lights suitable for vegetative growth, ensuring your moms stay bushy and healthy, ready to provide cuttings whenever you need them.

How to choose the best use for you

Not sure how to configure it? The beauty of the DP120 is that you don't have to choose permanently; it evolves with your cycle.

• Choose the Multi-Level Setup if: You need to root a large number of cuttings efficiently or start hundreds of seeds for an outdoor season.
• Choose the Open Setup if: You need to maintain mother plants or grow autoflowers in a compact space.
• Choose a Mixed Setup if: You want to keep a mother plant at the bottom and use a top shelf for rooting her cuttings.

Advantages and benefits that show up in every case

• Total Light Control: The fabric is 100% light-proof. You can have this tent in your bedroom or next to a flowering tent without worrying about light leaks disturbing cycles.
• Superior Reflection: The interior is lined with Mylar 190T (95% reflection), meaning you get better growth with less powerful lights, saving on your electricity bill.
• Built to Last: Features a robust structure with Q195 steel poles and reinforced corners, capable of supporting your lighting and Air Extraction System without sagging.
• Easy Climate Management: The breathable material and strategically placed socks for extraction/intraction make controlling temperature and humidity simple, which is vital for delicate seedlings.
• Water Tray Included: Comes with a waterproof bottom tray to catch any spills, keeping your floor clean and safe.

Frequently Asked Questions

What lighting is best for the DP120?

For propagation (clones/seedlings) on shelves, TLED strips or CFL tubes are ideal as they emit little heat. If you use it for mother plants (open space), a 250W CFL or a dimmable LED board works perfectly.

Does it come with the shelves?

The DP120 is designed to be compatible with grid shelves. Check the specific contents of the box upon purchase, but the structure is ready to support multiple levels to multiply your growing area.

Can I use it for flowering?

Technically yes, but it is optimized for vegetative growth and propagation. Its dimensions are perfect for small plants. If you flower in it, ensure you manage humidity well to avoid mold.

Personal Experience of Pevgrow’s CEO (Alan)

"I've used the Dark Propagator series for years to keep my favorite genetics alive. The DP120 is my favorite because of the height—190cm changes the game. I usually set it up with a mother plant at the bottom and a shelf at the very top for the rooting dome. It allows me to be self-sufficient; I never have to buy clones, and I know my plants are clean and pest-free from day one. It's an investment that pays for itself in the first harvest."
