Factors To Be Considered For Aquaponics Watermelon Farming

Media Base System

When growing aquaponic watermelon, the preferable and recommended method is the use of a Media Bed. It is also referred to as the Flood and Drain system. The watermelon growth bed is packed with gravel, lava rock, or expanded pebbles of clay as the growth media in this system. Water coming from the fish tanks gravitationally flows into the growth beds for the plants to access, or it can be pumped.

The Growing Medium

The perfect growing mediums for growing aquaponics watermelon are those that can effectively retain water. Some good options are Peat Moss and Coconut coir.

Peat Moss

The pH Requirements

Watermelon growth will require a 6.0 to about 6.8 range.

The Sunlight Requirements

Just like other plants, watermelons will require some amount of sunlight to thrive successfully. They will require at least eight to ten hours of sunlight daily. If this is impossible in specific environments, grow lights will provide the lighting needed.

Temperature and Water Requirements

Watermelons thrive well in warm climates. Water and air temperature of approximately 70 degrees Fahrenheit are ideal.


For your watermelons, provide spacing between six to twelve feet apart. This ensures that the watermelons do not compete for vital nutrients and water.

Planting and Harvesting

Watermelons can be grown from seeds. The seed sizes are pretty small, but peat starters can be used at the beginning till the growth is noticeable. Cover the plants if night temperatures in your environment go below 60 degrees Fahrenheit for heat retainment. When the roots develop, the plants can be transferred to the media bed, and the growth medium of your choice can now be used. Depending on your watermelon variety, flowers will start to show four to eight weeks into germination. With the spread of the vines starting, train them on a trellis or a support structure in your set system. Male flowers develop and appear first before the female ones. The females generate fruits and are the ones that remain on the vine. After thirty-five days, depending on variety, their full bloom will enable you to harvest.


Preferable Fish Type

For watermelon aquaponic gardening, the ideal fish is carp. Its association with a muddy taste makes some people avoid it, but the yields will taste good. Carp fish is watermelon compatible as they prefer warm temperatures of between 73°F to about 86°F.

Diseases and Pests

Your watermelons should be protected from pests such as cucumber beetles and aphids. Monitor for diseases such as powdery mildew and gummy stem blight.

How to Curb Common Aquaponic Watermelon Problems

Rotting – Store them in a cool environment with temperatures of under 50°F. When stored in a cool environment, they can be stored for about two weeks.

Spacing – Due to their size, ensure you have a considerable amount of space for growth.

Vine growth – Have a stout support framework, for example, a trellis or fence, as watermelons grow like vines.
