Overview

Like any type of crop production system, hydroponic greenhouses require periodic cleaning. Though plants grown hydroponically do not require soil, the liquid nutrient systems that help plants to thrive can leave behind deposits on the rooting chambers and the tubes that circulate the liquid. Regular cleaning of your hydroponic system will help prevent clogs, malfunctions or plant diseases. The best time to clean your system is in between crops when growing plants will not be disturbed.

Step 1

Drain all nutrient solution into a bucket and dispose of the solution.

Step 2

In the same bucket, mix a solution of one part bleach and nine parts water.

Step 3

Scrub all surfaces of the hydroponic system with a nylon brush. Scrub out any pipes with a bottle brush.

Step 4

Soak tubing in the bleach solution. Then scrub the inside of the tube with a pipe cleaner.

Step 5

Rinse all surfaces with a garden hose to remove any traces of bleach. Allow the hydroponic system to dry before restocking.

Tips and Warnings

  • The nutrients used in a nutrient solution can promote algae bloom when discarded down a drain. Instead, recycle your used hydroponic solution in a separate hydroponic chamber that is used to grow low-nutrient requiring herbs or flowers. This system will reclaim all usable nutrients. Once the nutrients are expended from this solution, it is safe to be poured into a drain system.
