IWS 20 Litre Pro Remote System – Flood and Drain

The 20 Litre Pro Remote IWS system you all the benefits of a flood and drain system, with the ability to grow larger plants
The IWS Pro Remote is the top of the range flood and drain system from IWS and, you may have guessed, features a remote timer that you can mount on a wall etc.
The remote timer improves on the, already impressive standard IWS system by allowing you to control the flood cycle from 1 minute up to 60 minutes.
The Pro system further improves the system by using larger 25mm pipework and a higher capacity 7000 lph pump, along with upgraded electronics.
These improvements allow much faster flooding and draining.

Flood and drain is a horticultural technique whereby nutrient rich solution is pumped into a container, filled with growing media, and then pumped back out.

The draining process draws air into the media which helps keep the rootzone healthy, promotes vigorous growth and exceptional yields.

IWS 20 Litre Flood and Drain systems can be used with a variety of media such as coco, 60/40(coco/clay), clay pebbles and some growers use soil but for the best results we recommend a good quality 60/40 mix such as Gold Label or Ecothrive Coco Clay.
