Start cucumbers indoors are easy to grow and make an excellent addition to any indoor garden. The seeds germinate quickly, and the plants can easily be transferred outside when the weather warms up.
Cuke plants can be grown in a variety of containers, including traditional garden pots and small AeroGardens, though we recommend using something that is tall enough for the vine to spread. They are also a great choice for hydroponic and aeroponic systems since they thrive in rich, well-draining soil.
Optimal growing conditions for cucumbers include warm soil and air temperatures. When growing indoors, we recommend starting cucumber seeds one to two weeks before the last frost date in your area, which is typically around mid-June.
Once the seeds have sprouted, move them into larger pots or seed trays as they grow. If you use a self-watering container, be sure to place it on the floor so that it drains away from the roots and does not splash moisture onto the leaves or seedlings (this can cause rot).

The cucumber plant needs plenty of light to flourish. We suggest positioning your containers in a sunny spot that receives at least six to eight hours of direct sunlight per day. Cucumbers can still grow in less than ideal sunlight, but you are more likely to see stunted growth or a slower rate of germination.
The cucumber plant is a vigorous grower and requires ample watering throughout the season. To encourage good fruit production, we recommend feeding the plants once a week with fish emulsion or soluble complete fertilizer at half strength. Watering should be done with care, as the soil can dry out very quickly.
