In Search of the Perfect Summer Crop

For many farmers, summer is the time of peak production and abundant harvests, but at the CLF Aquaponics Project our harvests peak mid-spring and start to decline as summer approaches. Farming is a learning process; and higher pest pressure coupled with hot temperatures in our hoophouse has made finding ideal summer crops a challenge.

Leafy greens and herbs are naturally some of the best crops for an aquaponics system, because they thrive in a nitrogen-rich environment. However, many of these greens prefer cooler weather, and as the temperatures in the greenhouse climb past 100 degrees Fahrenheit, even heat-tolerant chard gives up. We’ve found that many of summer’s star crops in the field, such as squash, tomatoes, beans and okra, simply do not produce well in our aquaponics system. The reason for this likely lies in the fact that these fruit-producing crops require high levels of potassium and phosphorous in comparison with leafy greens to encourage reproductive growth.
