🪴 14 cm hydroponic net pots : the Growrilla RDWC standard
The 14 cm (5.5 inch) net pot is the go-to format for RDWC and DWC growing as soon as you move beyond lettuce and herbs. It holds the substrate (rockwool, clay pebbles or coco coir, depending on your preference) and receives the young plant. Its walls and base are fully slotted to let the roots grow through and quickly reach down into the nutrient solution.
The heavy duty Growrilla version is reinforced with vertical ribs and a thick rim. It bears the weight of a mature plant with a root system of several kilos without deforming. The clip-on rim ensures a stable fit in the drilled lid of the 19 L bucket.

📦 When to order a pack of 10
A pack of 10 covers exactly one 8-pot RDWC kit with two spare net pots, or one 9-pot RDWC kit with no margin at all. It is also the ideal format for repeated use : net pots occasionally break when removing a mature plant, or warp after several cycles.
The net pot can also be used in aquaponics and classic hydroponics on any system fitted with a 14 cm drilled lid. Compatible with most buckets and tanks on the market.
🌱 Choosing the substrate for your net pot
Three options depending on your approach :
- Expanded clay pebbles : the simplest to use in standard RDWC.
- Rockwool cube : ideal for cuttings and young plants, then transition to pebbles.
- Coco coir : works too, but requires rinsing and pre-soaking.
💡 Pro tips : extending lifespan
When you remove a mature plant, the roots often colonise the slots and the net pot becomes impossible to extract without damaging the root system. Tip : if you want to keep the pot intact for reuse, cut the roots flush with the base rather than forcing it. The net pot will last another 2 to 3 cycles.
For root fragments stuck in the slots, a 30-minute soak in lukewarm water + 1 % hydrogen peroxide is usually enough to break down organic residue.
