This 3D printed hydroponic netpot (Ø8 cm) is specifically designed for 4×4×4 cm rockwool cubes.

Key features:

no clay pebbles required
open structure for unrestricted root growth
fits standard Ø8 cm openings/lids
lightweight yet strong design
Advantages over standard netpots:
cleaner setup (no loose media)

home growing (herbs, chili, vegetables)
seedling / early growth stages
Printing notes:

PLA is possible but less suitable for long-term water exposure
