IWS Dripper Systems - Precision Flood-and-Drain Feeding, 4 to 48 Pots
Best for: serious growers running multi-pot setups who want precise, automated feeding across a system that scales from a small tent to a full commercial room.
Our thoughts
This isn't an impulse buy, it's a proper commercial-grade dripper system, and the price range reflects that. What you're getting is a scalable range that runs from small 4-pot setups right up to 48-pot commercial configurations, all built around the same proven flood-and-drain delivery method. If you're growing at any real scale and want feeding on autopilot, this is the category to be looking at.
The IWS Dripper System is a hydroponic feeding system built on the same flood-and-drain technology used in IWS's other ranges, but delivered through drippers rather than flooding the whole tray. Nutrient solution is pumped from a control unit reservoir through a network of pipe, manifolds and pressure-compensated or flood drippers, delivering feed directly and evenly to each pot on a timed schedule.
It's available across two pipe standards, Standard 16mm for smaller-to-mid setups and Pro 25mm for higher-flow requirements, each offered on Small or Large stands and in pot configurations ranging from 4 pots up to 48 pots. Control units come in 1000 litre or 3000 litre capacities depending on the scale of the grow, giving genuine flexibility from a single-tent hobby setup to a full commercial room.
How it compares
IWS Dripper Systems sit in the active, pump-driven dripper category, distinct from passive gravity-fed systems.
- Versus Atami Wilma: Wilma integrates the dripper tray with a reservoir directly underneath for a compact all-in-one unit, while IWS separates the control unit and stands, giving more flexibility on layout and scale.
- Versus Autopot: Autopot relies purely on gravity and passive substrate suction with no pump or timer needed, making it lower-maintenance but less precise than IWS's timed, pump-driven delivery.
- Versus running individual pots on hand-fed timers: a dedicated dripper system delivers consistent, even feeding to every pot from one reservoir, rather than relying on multiple separate timers and lines.
You give up some of the "set and forget" simplicity of a passive system in exchange for tighter control over exactly how much and how often each pot is fed.
Usage guidance
Getting the configuration right at purchase matters, since this is a system you build around, not a single unit.
Choosing pipe standard
Standard 16mm suits smaller-to-mid setups with lower flow needs; Pro 25mm is built for higher flow rates across larger pot counts.
Choosing stand size
Small stands suit pots up to roughly 20 litres, Large stands suit pots up to roughly 45 litres, so match the stand to your pot size, not just your pot count.
Feed timing
Pair with a feed duration timer (such as an Imperium timer) to control exactly how long each drip cycle runs, rather than relying on a basic on/off mains timer alone.
Technical specifications

Who this is for
- Commercial and serious hobby growers running multiple pots who need consistent, automated feeding
- Growers scaling up from a small tent to a larger room over time
- Anyone who wants precise control over feed timing and volume rather than passive gravity feeding
- Not a fit for growers wanting a low-maintenance, no-pump, no-timer setup
Our take
This is a genuine range rather than a single fixed product, so the right configuration depends entirely on how many pots you're running and how much flow you need. Get that right and it's a dependable, well-established system for automated feeding at scale.
Proper kit at a price that makes sense once you factor in the labour it saves on larger grows.
