Net pots seem like a commodity until your roots start strangling themselves through three tiny holes. We tested 11 brands and three sizes to figure out which are actually worth buying.
Quick recommendations
- 2-inch: The standard for Kratky mason jars and most countertop kits.
- 3-inch: Best for DWC lettuce and herbs in 5-gallon buckets.
- 5–6 inch: Required for fruiting plants — tomatoes, peppers, strawberries.
What to look for
- Mesh-style sides (lots of slits all the way down) — not just three big holes at the top.
- Rigid plastic that doesn't deform under root weight.
- Standard rim: 2-inch net pots should fit standard mason-jar lids; 3-inch should fit 3-inch hole saw cutouts.
Top picks
1. 2-Inch Slotted Net Pots (50-pack)
The default. Buy in bulk — you'll lose, drop, and outgrow them. ~$12 for 50.
2. 3-Inch Heavy-Duty Net Pots
The sweet spot for bucket DWC. Big enough for kale and basil bushes, small enough to fit standard lids. ~$15 for 25.
3. 5-Inch Mesh Pots
For peppers, tomatoes, and strawberries. Pair with clay pebbles and an oversized bucket. ~$20 for 10.
What to skip
"Net cups" with three big holes. They might be cheaper but roots circle and strangle, especially in NFT channels. Worth the extra $2 per pack for proper slotted pots.

Frequently asked questions
What size net pot for lettuce?
2-inch for Kratky mason jars or countertop kits; 3-inch for DWC buckets and most NFT channels.
Can I reuse net pots?
Yes — rinse with diluted bleach (1:10) and they last for years. Discard any that crack or warp.
Do I need clay pebbles too?
For DWC, yes — they hold the plant upright in the net pot while letting roots dangle into the reservoir.
