Choosing the Right Variety When growing cucumbers indoors, select vining varieties that are well-suited for container culture. Some recommended varieties include:
– 'Telegraph Improved' - Classic long, dark fruit – 'Emilie' - Mid-sized fruit with smooth skin and good disease resistance – 'Mini Munch' - Perfect lunchbox sized fruit for greenhouse
Providing Ideal Growing Conditions Cucumbers thrive in warm temperatures between 70-85°F during the day and around 60°F at night. They also prefer high humidity around 50-70%, so mist plants regularly
Adequate light is crucial - cucumbers need at least 6-8 hours of direct sunlight daily. Use LED grow lights if natural light is insufficient, positioning them 6-12 inches above the plants.
Ensure good air circulation with inline fans to prevent disease and strengthen stems. Water when the top inch of soil is dry, being careful not to overwater.
Planting and Training Sow seeds 2-3 weeks before your last frost date in small pots using seed starting mix. Plant two seeds per pot and discard the weaker seedling.
Fertilizing and Harvesting Feed cucumbers every two weeks with a high-potash fertilizer like tomato food. This provides the nutrients they need for abundant fruit production
