The IWS Flood & Drain - The Great British Grow System that Delivers Massive Yields in Larger Indoor Gardens
The IWS Flood & Drain is a fully automated feeding system that takes the strain out of tending to larger numbers of plants. This system has been a customer favourite for over a decade, and there are very good reasons for that: it's simple to set up and run, it makes tending to commercial scale gardens quick and easy, it allows you to control feed times with complete precision, and come harvest time, it delivers the goods!
Culture Inner Pot (holds 6.5 litres of medium). This inner has fewer drainage holes, and is ideal for growing in coco or 60/40 clay/coco.
How the IWS Premium Flood & Drain Grow System Works
The IWS Premium Flood & Drain is a complete nutrient delivery solution that can be arranged to suit virtually any grow space. It's fully modular and adaptable, and can be upgraded to add new containers at any time.
Nutrient is pumped from the reservoir and out to the IWS Brain at user-specified times and durations (set on the IWS Minute Timer). The Brain is indirectly connected (via 13mm pipework) to the containers in the system; as it fills up, so do all of the containers. A float switch sits inside the Brain, which turns the nutrient flow from the tank off when the water level gets too high. The float height is the same as the top of the containers, preventing the system from ever flooding.
There are two parts to each container - an Inner and an Outer. The IWS Outer Pot connects to the pipework in the system, filling up with nutrient solution as the system floods. The inner pot sits inside the outer, and is perforated with holes. It contains the substrate and root-mass. As the outer fills up with nutrient the rootzone becomes saturated.
This premium version includes pot stands and the brilliant IWS Minute Timer, which allows you to control flood and drain cycles (sometimes called 'ebb and flood' cycles) with military precision.
This kit features Icetube Pipe - double-layered pipework that's white on the outside and black in the centre. The white outer layer reflects light and heat back towards your plants (where it's needed most), keeping nutrient temperatures in the sweet spot of around 18 degrees. At the same time, the black inner core works to protect against UV.
Also included is a custom-made IWS Flexi Tank. Flexi Tanks have been tested to absolute destruction and have never faltered yet. It offers all of the functionality of a standard water butt, with the ability to pack it away into a tiny space for easy transportation.
