Silent Hydroponic Kitchen Garden - Herbs Planter

Grow herbs like basil and oregano in your kitchen all year round. This indoor planter uses a passive hydroponic system, so it doesn't need a water pump and is completely silent. The setup is modular, and you can easily adjust the height of the LED lights as your plants get taller.

You're not limited to growing plants from seeds, either. The system also works perfectly with regular store-bought herbs in round pots. Simply use one of the included covers, which come in 100mm, 110mm, and 120mm diameters to fit different round pots.

Update May 2026: I have uploaded a STEP file containing various useful parts and components, allowing you to easily customize the design to better fit your needs.

Material: PETG is Highly Recommended

While PLA is great for many projects, this hydroponic system is in constant contact with water and moisture. Therefore, I strongly advise printing the main components—especially the water reservoir and the plant pods—in PETG.

Water Resistance:

PETG offers superior layer adhesion, making it much easier to achieve a completely watertight reservoir. PLA tends to degrade or warp over time when exposed to constant moisture.

Durability & Temperature:

PETG is more robust and handles the slight warmth emitted by the LED grow lights much better than PLA, ensuring your light canopy won't sag or deform over time.

Layer Height: 0.2mm Maximum

To ensure the system functions perfectly, print the parts with a maximum layer height of 0.2mm.

Watertightness:

Thinner layers mean better adhesion and fewer microscopic gaps, which is crucial for keeping the water basin leak-proof.

Coating: Food-Safe Epoxy

For optimal results and safety, all components that come into contact with water should be coated with a food-safe epoxy resin.

Important: Please join the plant pot and the pot carrier together during the coating process while the resin is still liquid, so that they bond and form a single unit. This eliminates any gaps where germs, viruses or bacteria could build up.
