Hydro Cloner 
is a simple and effective tool to help your clones root using just water and root stimulators.
 

The container holds about one liter of water and can accommodate a small ultrasonic humidifier, which fills the inside with humidity.

Thanks to the tray’s grids, the moisture rises up to the cuttings, keeping them hydrated and alive until they form roots —
the time needed may vary depending on the variety you’re cloning.
 

On top of the lid, there’s a plate where you can easily attach a small LED panel.
I picked one up from Aliexpress for just a few euros — white light, 12V, around 1.2 Watts.
 

The pot holes are sized for standard 50mm pots,but the printing file also includes two different pot designs:
the classic style you’ll find in stores and a version with three cone-shaped holders for sponges,
measuring 20mm across the top and about 55mm tall — feel free to use whichever you prefer!

There’s also a cap available if you leave any holes unused.

Required components:
Led Panel, 48 led
Ultrasonic atomizer

Optional, but recommended:
To boost the system’s performance, you can add a tiny recirculating pump (even a USB one) and a small aquarium air pump for extra oxygenation.

Liquid Solution:

Since this is a hydroponic system, the ideal mix would be 70% osmosis water and 30% tap water.
It’s important to keep the pH between 5.5 and 6.2.
If you don’t have access to commercial products, natural root stimulators work great too:
willow tree extract, aloe vera, and even a little pure honey, which also acts as an antibacterial and antifungal agent.

With this system and the right liquid solution, you’ll have strong, well-rooted clones in just a few days!
 

Hope you like it!
