Reliable flood and drain feeding with a straightforward setup. The IWS Flood & Drain Standard is a recirculating irrigation system built to deliver consistent watering across multiple pots without the daily hand-watering routine. It floods each pot evenly, then drains back to the reservoir, helping keep feeding uniform across the whole run while refreshing oxygen around the root zone as the system empties.
This is the ideal entry point into automated flood and drain. It keeps the process simple, stable, and repeatable, making it easier to maintain a balanced environment through veg and flower.
Key features
- Automated flood and drain cycles to keep every pot on the same feeding routine.
- Recirculating design returns nutrient solution back to the reservoir for efficient feeding.
- Even flood height helps deliver uniform saturation across all sites.
- Root zone oxygenation as the system drains, fresh air is pulled through the medium.
- Scalable layout suitable for multi-pot tents and grow rooms.
How it works
- Flood: Nutrient solution is pumped from the reservoir to saturate each pot site.
- Feed: Plants take up water and nutrients during the flood window.
- Drain: Solution returns to the reservoir and air is drawn through the medium to refresh oxygen around the roots.
- Repeat: Timed cycles keep feeding consistent day after day.
Key benefits
- Consistency across every plant, reducing the variation you get with hand-watering.
- Less work once dialled in, with fewer daily tasks and fewer missed feeds.
- Healthier roots supported by regular oxygen exchange through the medium.
- Clean, repeatable routine that helps keep your environment stable.
What’s typically included
- Controller unit
- Outer pots with inner pots (style depends on the kit variant)
- Fittings and pipework
- Flood pump
- Pot stands
- Reservoir (size varies by kit configuration)
Media compatibility
Flood and drain systems work best with free-draining media such as clay pebbles, or with coco and mixed media when the correct inner pot style is used. Keep the reservoir clean and ensure pipework stays clear to maintain reliable filling and fast drainage.
Best for
- Growers who want simple, proven automation with consistent feeding across multiple pots
- Tents and rooms running multi-plant setups
- Anyone upgrading from hand-watering to a repeatable flood and drain routine
Tip: Start with a conservative flood schedule, then increase frequency as plants grow and demand rises. Consistency and cleanliness are what make flood and drain systems shine.
