How Long Does Hydroponic Lettuce Last? Tips for Keeping it Fresh

Hydroponic lettuce is a great way to have fresh greens all year round, but one of the main concerns is how long it will last. Fortunately, hydroponic lettuce can last up to four weeks, as long as it was harvested with the roots in good condition. Here are some additional factors that can affect the lifespan of your hydroponic lettuce:
  • Temperature: Hydroponic lettuce thrives at temperatures between 60 and 68°F. If the temperature is too cold or too hot, the lettuce may wilt or become slimy.
  • Humidity: Lettuce prefers humidity levels between 90% and 95%. If the humidity is too low, the leaves will dry out and become tough. If the humidity is too high, it can lead to mold or rot.
  • Light: While hydroponic lettuce needs light to grow, too much or too little light can impact its lifespan. Be sure to provide your lettuce with 12-16 hours of light per day and keep the light source at the appropriate distance to prevent burning or stunting growth.
  • Nutrients: Hydroponic lettuce needs a balanced mix of nutrients to thrive. Make sure your nutrient solution is properly mixed and pH balanced for optimal growth and to prevent nutrient deficiencies. By paying attention to these factors and maintaining good growing conditions, you can maximize the lifespan of your hydroponic lettuce.
