Small Propagator for Cuttings – Professional Greenhouse for Clones & Seeds

The Small Propagator for Cuttings is your best ally to ensure a 100% success rate when rooting clones or germinating seeds. It is a professional hard plastic mini-greenhouse designed to maintain the high humidity levels and stable temperature your plants need to survive their first critical days of life.

Why do you need this propagator?

Are you tired of cutting healthy clones from your mother plant only to watch them wilt, turn yellow, and die within a few days? Or maybe you are frustrated because your expensive seeds don't pop because the environment is too dry? These are the most common problems for growers, and they usually happen because young plants without roots cannot absorb water from the substrate; they need to absorb moisture through their leaves.

If you don't control the environment, the dry air in your room or grow tent will dehydrate your cuttings faster than they can recover. This leads to a mediocre survival rate, wasted time, lost genetics, and the frustration of having to start all over again. Trying to root clones on an open shelf is basically a death sentence for them.

The solution is simple: this propagator creates a perfect microclimate. By sealing the moisture inside, it keeps the relative humidity close to 90%, which is exactly what your clones need to stay turgid and focus their energy on developing roots. It turns a risky process into a predictable, stress-free routine.

Maximum versatility for your indoor grow

This propagator isn't just a plastic box; it's a multi-purpose tool that improves your daily workflow. Its compact size (38x24x19 cm) allows you to fit it into small spaces, on top of a closet, or in the corner of your grow tent without getting in the way. It is perfect for rooting about 20 to 25 cuttings, which is ideal for self-cultivators who don't need industrial quantities.

Beyond cannabis, this unit is excellent for germinating Vegetable Garden Seeds or even for the cultivation of hallucinogenic mushrooms. Mushroom kits require very stable humidity and temperature conditions to fruit properly, and this greenhouse provides exactly that environment, protecting your mycelium from contamination and dryness.

How to use the propagator for success

Using this greenhouse is straightforward, but following the right steps ensures you get white, healthy roots in record time.

1. Preparation: Clean the propagator with water and a little bleach or alcohol to ensure it's sterile.
2. Substrate: Prepare your rooting medium. We highly recommend using Jiffys (peat pellets) or rockwool cubes, as they fit perfectly in the tray.
3. Cutting: Take your cuttings, dip the stem in a good rooting hormone like Clonex Rooting Hormone Gel (50ml) | Growth Technology, and place them in the moist substrate.
4. Placement: Arrange the clones inside the propagator. Spray the inner walls of the clear lid with water to spike the humidity immediately.
5. Ventilation: Close the two ventilation windows on the lid completely for the first 2-3 days. You want maximum humidity (around 90%).
6. Acclimatization: From day 4, open the windows slightly to lower humidity gradually. This forces the plants to search for water with their roots.
7. Transplant: Once you see roots poking out of the Jiffy or cube, they are ready to be moved to a larger pot.

Key advantages and benefits

• Adjustable Ventilation Windows: The lid features two rotating vents. This allows you to precisely control airflow and humidity, letting you "harden off" plants gradually without shocking them.
• Transparent Lid: Made of high-quality clear plastic. This ensures your plants receive the necessary light for photosynthesis without being exposed to the harsh direct environment.
• Compact & Durable: Measuring 38x24x19 cm, it fits anywhere. The rigid plastic base is tough and easy to clean, meaning you can reuse it for years.
• Waterproof Base: The tray holds excess water, preventing leaks and allowing you to water from the bottom if needed.
• Multi-use: One investment serves for cloning, seed starting, and mushroom growing.

Care and maintenance

To keep your propagator in top shape, hygiene is non-negotiable. After every cycle of cuttings or seeds, wash both the tray and the lid with warm soapy water. It is crucial to disinfect it to prevent fungi like Pythium or mold from attacking your next batch of seedlings.

Store it in a cool place away from direct sunlight when not in use to prevent the plastic from becoming brittle over time. If you are using it in a cold room, consider placing a heating mat underneath, but always monitor the temperature to avoid cooking the roots.

Frequently Asked Questions

How many cuttings fit in this small propagator?

You can comfortably fit between 20 and 25 cuttings using standard Jiffy pellets or rockwool cubes. It's the perfect size for a home grower's cycle.

Does it include a heating system?

No, this is a passive propagator. However, the plastic is compatible with external heating mats if you need to raise the temperature in winter.

Can I use it for mushroom kits?

Absolutely. Its dimensions and ability to retain high humidity make it an excellent fruiting chamber for small mushroom cakes or kits.

Personal Experience of Pevgrow’s CEO (Alan)

I've used dozens of propagators over the years, and honestly, for a home setup, you don't need anything more complicated than this. The small model is my go-to when I'm popping a new pack of seeds or taking a few cuts to preserve a phenotype. It's simple, it works, and it doesn't take up half my grow room.

My personal trick is to keep the vents fully closed for the first 48 hours and spray the dome, not the plants directly. This creates a fog effect that keeps them happy without soaking the leaves too much, which can sometimes lead to rot. Once I see the leaves perking up towards the light, I know they are rooting, and I start opening the vents.
