Cucumbers

Summary

Cucumbers are a great, high value, crop to grow in the summertime. They do well in media beds, due to large root structures. Due to a high uptake of nitrogen and potassium, the quantity of cucumbers grown in your system may be limited.

Growing

Cucumbers grow optimally at around 24-27°C with a humidity from 70-90%. Pollination via insects is important for good fecundation and fruit set. Additionally, adequate aeration is necessary to prevent mold or mildew growth; which can be achieved with support.

Once seedlings have grown at least 4 true leafs they can be transplanted into the system, usually after 2-3 weeks. Removing apical tips after the crop has matured may help to limit nutrient waste.

Harvesting

Cucumbers can be harvested 10-15 times, starting after 2-3 weeks. Harvesting frequently may be necessary to prevent fruit from excessive growth.

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.
