Whether you are growing sweet peppers or hot peppers, media beds are the ideal aquaponics method to use.


Peppers grow well within a humidity range of 60-65% and a temperature range of about 22-28°C. Generally speaking, spicier peppers can be grown at higher temperatures; though exceeding 30°C for extended periods of time can lead to floral abortion.

Pepper seedlings can be transplanted after at lest 6 true leaves have presented and the evening temperatures stabilize above 10°C. Heavy yielding pepper plants will likely need to be trellised. Removing some of the frist flowers encourages further plant growth and may lead to a higher yield.


Harvest peppers once the color changes to a ripe and rich shade indicating elevated vitamin C levels and have reached a marketable size.

Nutrient Availability

The availability of macro and micro nutrients varies depending on the pH of your system. The chart below displays the pH range and the nutrients that would be available within an Aquaponics system. The Aquaponics system pH range is also indicated below in blue.
