Net Cup, 3.75" (Bag of 100)

A Slotted Mesh Net Cup for Hydroponic Root Support, 3.75in

Media-filled hydroponic sites need a container that lets water and nutrient solution reach roots from every direction rather than just the bottom, which is exactly what a solid-walled pot can't do. This Hydrofarm 3.75 inch net cup uses slotted sidewalls that let water and nutrients reach roots from all sides while still supporting clay pebbles, rockwool, or other growing media inside the cup.

Sized for medium containers, this 3.75 inch net cup ships in a bag of 100 and fits standard net pot grow sites in ebb and flow tables, deep water culture buckets, and similar hydroponic setups.

Key Features & Benefits

• Slotted mesh sidewalls — let water and nutrient solution reach roots from all sides, not just the bottom

• Sized for medium containers — a 3.75 inch diameter matched to that use case
• Fits standard net pot grow sites — drops into common ebb and flow, DWC, and NFT hardware without modification
• Bag of 100 — for growers outfitting a full hydroponic table or system at once

Who Should Use This Net Cup

Hydroponic growers running ebb and flow, deep water culture, or NFT systems who need a net cup sized for medium containers will benefit from this 3.75 inch cup.

Frequently Asked Questions

What size is this net cup?

This listing is for the 3.75 inch Hydrofarm net cup, sized for medium containers. It's built to the diameter of a standard net pot grow site.

How many net cups come in this bag?

This listing ships in a bag of 100 net cups. That count is meant for growers filling out a full hydroponic table rather than replacing a single cup.

How does a net cup work in a hydroponic system?

The slotted mesh sidewalls let water and nutrient solution reach plant roots from all sides while still holding growing media like clay pebbles or rockwool in place around the root zone. This differs from a solid-walled pot, which only lets water reach roots from the drainage holes.

What growing media works in this net cup?

Clay pebbles (expanded clay/hydroton), rockwool cubes, and similar coarse hydroponic media all work well. The slotted sidewalls are sized to hold these materials in place while still allowing water flow.

Will this net cup fit my hydroponic system?

It's sized to fit standard net pot grow sites used in ebb and flow tables, deep water culture buckets, and similar hydroponic hardware. It's still worth confirming the site opening diameter on your specific system before ordering in bulk.
