SUNPACK Mesh Net Cup | 3in

Open-Mesh Net Cup for Direct Root-Zone Airflow, 3in

A solid-walled pot blocks a hydroponic root system from the oxygen and nutrient contact its roots get in a mesh design, since roots can only draw from the growing medium directly inside the container. SUNPACK Mesh Net Cups use an open mesh wall that lets roots grow directly through the sidewalls, giving them access to air and nutrient solution beyond the growing medium held inside the cup.

This 3in cup suits a young plant that has outgrown a 2in cup but doesn't yet need a full-size cup.

Key Features & Benefits

• Open Mesh Sidewalls — let roots grow through the cup wall for direct air and nutrient contact.
• Improved Air Circulation — supports stronger root development compared to a solid-walled container.
• Built for Hydroponic Systems — sized to sit in standard net cup openings in hydroponic setups.
• Reusable Design — can be cleaned and reused across growing cycles rather than treated as disposable.

Who Should Use Mesh Net Cups

These cups fit growers running hydroponic systems such as deep water culture, NFT, or ebb-and-flow setups where roots need direct contact with nutrient solution or a misted root zone rather than a solid, soil-filled container.

Frequently Asked Questions

How does a mesh net cup improve on a solid pot for hydroponics?

The open mesh sidewalls let roots grow directly through the cup wall into the surrounding nutrient solution or misted root zone, instead of staying confined to whatever growing medium sits inside a solid pot. That direct contact with air and nutrients is central to how most hydroponic system designs are meant to work.

What growing medium goes inside a net cup?

Net cups are typically filled with an inert medium like clay pebbles, rockwool, or coco coir that holds a plant upright while still letting roots grow out through the mesh. The medium itself doesn't supply nutrients; that comes from the surrounding hydroponic solution.

How do I choose the right net cup size?

Match the cup diameter to the opening size in your hydroponic system's lid or tray, since a cup that's too small will slip through and one that's too large won't seat properly. Larger cups also hold more growing medium, which suits bigger plants with more root mass.

Can net cups be reused between grow cycles?

Yes, net cups are built to be cleaned and reused rather than treated as disposable. Sanitize them between crops to reduce the risk of carrying over pathogens from one planting to the next.
