Auto Pot 3.9 Gallon Pot

The Auto Pot 3.9 Gallon Pot is the official replacement square pot for AutoPot easy2grow and 1Pot modules and systems. If an existing pot cracks, splits, or becomes damaged over time, this is the direct like-for-like replacement — same shape, same capacity, same fit — so your autonomous watering system keeps running without improvised workarounds.

Auto Pot 3.9 Gallon Pot Specifications

Specifications below are drawn from the canonical product listing (SKU APWS055) and the AutoPot system documentation. The 3.9-gallon / 8.5-litre square pot is the standard vessel used across the easy2grow and 1Pot product lines.

Why Choose the Auto Pot 3.9 Gallon Pot

AutoPot systems are built around specific pot dimensions that sit correctly in the module tray and align with the AQUAvalve float mechanism. Using a generic round or oversized pot in an easy2grow or 1Pot tray is not a reliable substitute — the square profile and base dimensions of the APWS055 are what allow the gravity-fed watering cycle to work as designed.

• Direct system compatibility: Engineered specifically for the AutoPot easy2grow and 1Pot module trays. The square base fits the tray footprint so the pot sits level and drains correctly at the end of each watering cycle.
• Like-for-like replacement: If a pot in your existing AutoPot setup cracks or warps, swapping in this part returns the system to factory condition. No re-engineering or improvising around a non-standard vessel.
• Works with any compatible growing medium: AutoPot systems are medium-agnostic. This pot can be used with coco, clay pebbles, perlite mixes, or other well-draining substrates — the same as the original pot it replaces.
• Modest root volume for targeted crops: At 3.9 gallons, the pot is well-sized for single-plant growing of tomatoes, peppers, cucumbers, cannabis, and other medium-to-large annual crops in an automated setup.
• Priced as a consumable part: At under $13, growers running multi-pot systems can keep a spare on hand without significant cost, minimizing downtime if a pot fails mid-cycle.

Best Uses for the Auto Pot 3.9 Gallon Pot

This pot is a replacement part, not a standalone growing vessel. It is intended for growers who already own an AutoPot easy2grow or 1Pot system and need to restore a damaged module to working order, or who are expanding an existing AutoPot setup by adding modules.

• Replacing a cracked or damaged pot in an active easy2grow or 1Pot system without taking the whole setup offline.
• Expanding an AutoPot system by adding pots to a multi-module configuration when additional grow sites are needed.
• Growing single, large annual plants — tomatoes, peppers, herbs, or cannabis — in a gravity-fed automated environment where the 3.9-gallon volume suits a full-cycle grow from transplant to harvest.
• Coco and perlite growers who run AutoPot systems and need a pot that drains cleanly at the low-water phase of the AQUAvalve cycle.
• Indoor and greenhouse grows where consistent automated watering reduces daily maintenance and the square pot profile makes efficient use of bench or tray space.

If you are building a new container setup from scratch and are not already using an AutoPot system, consider whether a fabric pot or a different container format better fits your watering method before purchasing this part.

Compatibility

The Auto Pot 3.9 Gallon Pot (APWS055) is confirmed compatible with the following AutoPot system lines:

• AutoPot easy2grow — the dual-pot, single-tray module designed for two plants per AQUAvalve unit.
• AutoPot 1Pot — the single-plant module used in 1Pot XL and standard 1Pot system configurations.

The pot is not confirmed to fit other AutoPot product lines (such as FlexiPot, TreePot, or AutoPot Easy2Grow XL variants with different tray dimensions). If you are unsure which pot size your system uses, check the model number on your existing tray or the documentation included with your AutoPot kit before ordering.

The pot is medium-agnostic and compatible with standard hydroponic and soilless substrates, including coco coir, clay pebbles (hydroton/LECA), and well-draining perlite blends. Do not use fine-particle media such as rockwool crumble or potting soil without a coarse drainage layer, as these can interfere with the passive drainage cycle of the AQUAvalve mechanism.

For storage or mixing purposes in a larger growing setup, a gamma seal lid paired with a standard bucket can be a useful companion for nutrient solution prep alongside an AutoPot reservoir system.
