Description

Up to 80 plants can be managed from one timer and one water butt, with the IWS Flood and Drain – The most popular modular hydroponic system.
How IWS Flood and Drain hydroponic systems work
At the set times solution is pumped from the water butt into each pot allowing the plants to feed and pushing out air. Floats ensure the same level of solution rises into every pot.
When the solution drains from the pots fresh air is pulled into the rootzone. The drained solution is pumped back to the water butt, rebalancing the pH and EC.
Because stale air is replaced with fresh oxygen-rich air at every feed the roots are well oxygenated which drives more productive growth.
Drainage is excellent with this grow system, so it is important to remember to increase the amount of feeds as the plants grow.
Perfect for growers who want to:
Choose how to space pots
Benefit from the oxygen-rich nature of pebbles
Finely tune feeds
Grow on a larger scale or add pots at a later date
Manage one water butt for many plants
