Maintaining cleanliness in your flood and drain hydroponics system, also known as an ebb and flow system, is crucial for ensuring optimal plant health and system efficiency. Regular upkeep can significantly reduce the need for extensive cleanings. Here’s a comprehensive guide to keeping your system in top shape, using only water, damp cloths, and simple tools.

Regular Maintenance During Harvest

Remove Fallen Leaves: Regularly check and remove any fallen leaves from the system.
Trim Dead Branches: Prune dead branches to prevent decay and disease.
Wipe Down Surfaces: Use a damp cloth to wipe down small areas, keeping the system tidy.
Routine Checks: Regularly inspect for any signs of mold, algae, or residue and address them immediately.

Note: Big Cleanings Are Rarely Needed

Minimal Need for Big Cleanings: If you maintain your system well, big cleanings are generally only necessary if you’ve been running the system for over a year without significant upkeep.
Preventive Care: Consistent, small maintenance efforts can keep your system running smoothly and reduce the need for major overhauls.
