Best Hydroponic Net Pots of 2026

A hundred net pots is a commitment. A hundred net pots with a hundred feet of wicking cord and a hundred labels is a starter kit. That cord is the part that changes what you can build: thread it up through the bottom of a cup, pack the medium around it, and leave the other end in a jar or bucket, and water climbs to the roots without a pump or a timer.

The cups are the standard 2-inch pattern, slotted on the sides and open at the bottom, with a lip that flares wide enough to sit on the rim of the hole instead of sliding through it. That flare is forgiving, which counts when the lid you drilled is not perfectly round.

They are polypropylene, so a season outdoors does not leave them chalky, and the mesh openings are big enough for roots to escape but small enough to hold clay pebbles. A hundred identical black cups is exactly where the included labels earn their place; by midsummer you will not remember which jar holds the basil.

For filling a tower or a whole shelf of Kratky jars, this is the best value in bulk here, because the extras are things you would otherwise buy separately. Cut the wick generously, about a foot per cup, and trim it after the medium is in, since you cannot add length once it has been threaded through the bottom.

Same hundred 2-inch cups as the ORIMERC kit, minus the cord. What Tmtamye adds instead is a raised bottom on every cup, so they stand upright while you fill them, and 20 plant labels for keeping a hundred identical pots straight. If you already have a spool of wick in the shed, this is the better of the two bulk boxes.

The wide rim is the other point in its favor. It flares enough to bridge a hole that came out slightly oversized, and the plastic is on the thick side for a 2-inch cup, built to be pulled out, rinsed and put back rather than used once. UV resistance is stated, which matters on a patio where the sun reaches the reservoir.

Fit is the one thing to check. Some tower sites are molded tightly, and a wide-rimmed 2-inch cup can be a fraction too large to seat all the way down, so measure a site on your tower before ordering a hundred.

These are the most expensive cups in this guide, and the money goes into the wall. Where an economy cup gives when you squeeze it, this one stays rigid, with a lip heavy enough that it does not split when it is levered out of a snug hole. If you have ever had a cheap pot crack at the rim halfway through a crop, that is the failure this design is built against.

The interior is the detail we did not expect to care about. Vertical ribs run down the inside wall and steer roots toward the slots instead of letting them circle smooth plastic, which shows up at the end of a crop when you pull a root ball out in one piece rather than in fragments. The lip measures about 2.6 inches across, so it seats over a 2-inch hole saw cut with room to spare, and the polypropylene is UV-resistant and BPA-free. Fifty to a box, meant to be rinsed and reused.

What you do not get is depth. The body is roughly 2 inches tall, so it holds less medium than a 3-inch cup and suits lettuce, herbs and starts better than a full-size tomato. That short body is also why it drops cleanly into mason jar lids and Dutch bucket sites without wobbling.

Nobody knows their hole size for certain the first time. This box answers the question by refusing to choose: 20 two-inch cups and 20 three-inch cups, enough of each to plumb a small system and find out what your lids and jars actually want.

As a first purchase for someone building a DIY setup from scratch, that is hard to beat, because you are buying information as much as plastic. The cups feel sturdy, the mesh is properly slotted, and the 3-inch ones seat in a wide-mouth jar. Run the small cups for lettuce and a couple of the big ones for a tomato, and by the end of the season you will know which size to order in bulk.

The split is fixed at 20 and 20, so if you already know you are a 3-inch grower, half the box becomes spares and two single-size packs make more sense. The 2-inch cups are also for drilled lids and small sites rather than narrow-mouth jars, so do not count on them for every container in the cupboard.

A wide-mouth quart jar, one 3-inch cup and a wick is the whole of a Kratky setup, and this box has the makings of 25 of them. Inside are 25 cups, 25 feet of capillary cord and 25 labels, which is enough to line a windowsill without buying a hundred of anything.

The lip is generous at about 3.2 inches across, more than a jar mouth needs. That overhang is the useful part: it sits flat, covers the rim so light does not pour into the water, and saves you when the lid you cut is not quite round.

Three inches of basket holds a decent charge of clay pebbles, which is the difference between a cup that carries lettuce and one that can take a pepper plant through the season. The polypropylene is stiff enough that the rim does not fold when you lift a loaded cup out of a jar.

Nothing here puts a wick-fed jar together for less, and 25 pots is about a season of windowsill growing rather than a lifetime supply. Plan on one jar per plant and a bucket for anything past a pepper, because a quart runs out of room once a tomato starts setting fruit.

A thin lip is the design brief here. These are the lightest 2-inch cups in this guide, with a slim rim and a mesh body that flexes in the hand, sold 50 to a box.

Lightness is the point. Fifty of them add almost nothing to a rack, they stack into a small box between seasons, and a full tower of them does not load up a flimsy frame. The plastic is BPA-free and UV-resistant, and the mesh is slotted the same way as the heavier cups, so roots and drainage behave the way you expect.

For a tower with dozens of holes, or a first season where you are not sure the hobby will stick, this is the sensible buy: enough cups to fill every site without wincing. Seat them with a flat palm rather than levering on the rim, and if your lids are hand-cut with a wandering hole saw, a wide-lipped cup will hold where these will not.

If your hydroponic system is a countertop unit with seven pods and a small pump, none of the 2- and 3-inch cups here are the right shape. These 1.75-inch baskets are the replacement size for that class of machine, and 50 of them refill a seven-pod unit many times over. This is the box we point people to when the pods turn out to be the expensive part of running a countertop garden.

The measurements matter more than anything else here. The cup is about 1.75 inches across and the same tall, the inner basket tapers to roughly 1.2 inches, and the bottom hole is about 0.39 inches, wide enough to pass a wick or a root bundle and too narrow to dump a sponge. That inner diameter is the number to hold against your unit, because it holds a small root plug and a little medium, not a full-size plant.

The walls are stiff rather than flexible. That is why they keep their shape in a pump-fed machine, and also why a root-bound plant takes more coaxing to lift out. Measure the pod opening before ordering: a genuine 2-inch site has nothing for a 1.75-inch rim to catch on, and the cup will drop straight through.
