The IWS flood and drain system works by flooding all the pots up to the same level to fully saturate the growing media, it then 'sucks back' all the nutrient solution via the brain bucket to the main reservoir. You simply set the frequency and duration of the floods based on plant size and stage of growth, growing substrate being used and size of system.
The standard in flood and drain pot systems the IWS has featured in many grow rooms across the country. it comes with a precise IWS remote minute timer for accurate flood cycles, 13mm pipework and includes pot stands for better drainage.
