Dialled-in flood & drain performance for tighter footprints. The IWS Flood & Drain PRO Remote is a fully automated recirculating feed system built for growers who want consistent irrigation, faster root-zone oxygenation, and repeatable results, without daily hand-watering. The 16L pot option is ideal when you want a more compact setup, quicker dry-backs, and efficient use of space while still keeping the benefits of a proper flood & drain cycle.
Designed around rapid fill + rapid drain, the PRO Remote floods each pot evenly, then drains back to the reservoir, pulling fresh air through the medium as it empties. That regular exchange helps keep roots oxygen-rich and feeding consistently, especially when you’re running multiple pots and want uniform performance across the whole room.
Why it’s “PRO”
- High-flow 25mm pipework for faster filling and drainage than standard flood & drain layouts.
- Remote timer control with minute-adjustable scheduling (perfect when you want easy access outside the grow space).
- Strong flood pump performance to deliver even saturation across multi-pot runs.
- Consistent flood height control to help keep irrigation uniform and reduce over-filling risk.
- Oxygen advantage: as the system drains, stale air is drawn out and replaced with fresh oxygen around the root zone.
How it works
- Flood: Nutrient solution is pumped from the reservoir to evenly saturate each pot.
- Soak: Plants feed while the root zone is fully saturated.
- Drain: The solution returns to the reservoir and fresh air is pulled through the medium—re-oxygenating the root zone.
- Repeat: Timed cycles keep growth consistent and predictable.
Key benefits
- Compact efficiency—ideal for tighter rooms, tents, and clean multi-pot layouts.
- More control than hand-watering—every pot receives the same feed cycle.
- Less labour and fewer inconsistencies once dialled in.
- Healthier roots through regular flood/drain oxygenation.
- Scales well for repeatable runs with multiple sites.
What’s typically included
- Controller/brain unit
- 16L pots (outer pots) with inner pots (style depends on the kit variant)
- 25mm fittings and pipework
- Flood pump
- Remote timer
- Pot stands
- Reservoir (FlexiTank size varies by kit configuration)
- Root control accessories (where supplied)
Media compatibility
The 16L PRO Remote is commonly run with clay pebbles, coco, or mixed media depending on the inner pot style supplied with your kit. For finer media, keep flow paths clear and consider a drainage layer to maintain fast, reliable drainage.
Best for
- Growers who want compact pot sites with fast cycling and strong oxygenation
- Multi-pot setups needing even feeding across every plant
- Anyone upgrading to a repeatable automated irrigation system with high-flow performance
Tip: Flood frequency should match your medium and environment. Smaller pots can dry back quicker, so start conservative and increase cycles as plant size and demand rises.
