IWS Control Units for Flood and Drain Systems

Minute-Accurate Irrigation, Cycle After Cycle

IWS Control Units are the brain of an IWS hydroponic system, managing water and nutrient delivery to the pots and pulling solution back to the reservoir on schedule. Built-in minute timers set irrigation cycles precisely rather than in coarse blocks, which is what separates a system that feeds the root zone properly from one that leaves pots waterlogged or bone dry. Waterlogging is the fast route to root rot, weak roots and poor nutrient uptake. Automating drainage and delivery keeps the root zone in the same state every cycle. The units suit Flood & Drain, Dripper Pro and AutoDrain setups and scale to 48 pots, with Standard, Pro and Remote brains, timer-only and brain-only modules, and dedicated AutoDrain controllers in the range.

Key Benefits

• Built-in minute timers for irrigation cycles tuned to the minute, optimising hydration and nutrient uptake
• Works across Flood & Drain, Dripper Pro and AutoDrain systems without changing your layout
• Scales to 48 pots, so the same control approach carries from a tent to a full room
• Automated fill and drain keeps conditions consistent without you standing over it
• Stronger root zones by preventing waterlogging and managing run-off
• Straightforward installation for growers at any level of experience

How to Use

• Choose the right unit for your system – Standard with an integrated timer, Pro or Remote with a separate brain and timer, or AutoDrain for automated draining
• Site the brain above the reservoir and connect the air line and pot feeds as laid out in your IWS system
• Set fill and drain times in minutes, building up as the root mass develops
• Choose the two drain outlet version where a larger run needs to clear faster
• Check pots empty fully after each cycle before increasing frequency
