About the Design:
This versatile 3D-printable bucket lid is designed for growers seeking flexibility, whether you're starting seedlings, growing leafy greens, or rescuing plants from a hydroponic tower. Compatible with standard US 5-gallon buckets (and also fits 3.5 and 7 gallon variants), this lid features 41mm and 60mm holes—the perfect size for modular tower-style planting cups or the included printable cups.

 

The 41mm holes are compatible with the Hoocho tower cups from his updated starter and modular tower system.

 

Multiple Grow Methods Supported:

• Kratky Hydroponics: Use standalone without pumps for low-maintenance leafy greens.
• Wicking Hydroponics: Each cup is designed to accommodate wicking cords to gently pull nutrient solution up to your plant roots.
• Deep Water Culture (DWC): Easily adaptable for active systems by adding an air pump and sprayer or drip line.

Flexible Use Cases:
✔️ Grow leafy greens, herbs, and smaller plants right in a 5-gallon or 3.5-gallon bucket.
✔️ Use as an intermediate growth station before moving plants into a hydroponic tower.
✔️ Great for reviving struggling plants removed from a tower — supports standard tower cups.
✔️ Easily swap between Kratky, wicking, or DWC methods depending on plant needs.

 

What’s Included in the Files:

• Lid Design (single, 3-site and 7-site versions included!)
• Printable Cups (Kratky and Wicking, and Tower Compatible Styles)
• Wicking Cord-friendly Inserts

Recommended Printing Notes:

• Print in PETG for maximum durability, food safety, UV, and humidity resistance.
• No supports are required for the main lid and most cups (easy printability).

Perfect For:

• Home hydroponic growers
• DIY indoor and outdoor gardens
• Modular and scalable systems
• Beginners and pros alike

 

Assembly:

Print the 3 sections of the lid and use zip ties to connect them into a single lid.  Use a minimum of 2 zip ties for smaller plants or add a 3rd or 4th for extra strength.  

 

Buckets:

This was tested with various buckets, including Home Depot, Lowe's, ePackageSupply, and Leaktite buckets.
