IWS Flood and Drain 16mm (13mm) Systems

Ready for giant yields in a system that’s easy to manage with a flexible layout? Invest in the tried, tested, proven 16mm IWS Flood & Drain System.

How's it work? It’s all about getting oxygen to the roots.  

When feeding, plant pots are flooded with feed. When feeding ends, pots are quickly drained of feed. This locks oxygen in the rootzone, to drive nutrient uptake, fuel growth & prevent nasty root diseases.

It's simple, but it works. 

• Flood & drain growing system
• 13mm inner diameter pipes (16mm outer diameter)
• Handy fixed timer (15 minute segments)
• Flexible, modular layout – position pots how you want
• Easy to manage – pots are filled from a 1 tank
• Quiet – the pumps hardly ever on!
• Saves headroom - pots sit on the floor
• Low waste! Drained feed is stored for recirculation
• Extreme oxygen – better roots, growth, nutrient uptake
• Simple to set up and program

Waste is low - drained feed is stored between floods. It'll run quietly too, the pump's hardly ever on! 

It’s easy to fine tune your flood times– you get a fixed timer (1 minute segments). 

Your layout’s flexible…expand it & position pots however you want – all pots are connected to a central feed tank individually or in groups. Pots sit on the floor too, height's hardly an issue. 

1. Choosing your media

Use clay pebbles – they hold lots of air, but hardly any nutrients. They’re perfect for flood and drain.

Or

To flood less often, mix 20 – 40% of coco with 60 – 80% of clay pebbles. The mix will hold more water, so you can flood less often. You can mix this yourself, or buy it pre-mixed.

2. Keeping a sterile system

Keep your system sterile with Silver Bullet Roots. It kills 99.99% of root diseases and stays active in tanks for 5 weeks!

If you already use Oxy-Plus 11.9%, switch to Silver Bullet and you’ll save 55%.
