Growing cucumbers indoors

growing cucumbers indoorsThe methods and principles for growing cucumbers indoors are very similar to that of many indoors plants.

There are certain requirements that you should follow if you want to get the most out of your efforts.

The cucumber is thought to originate from Eastern Africa/Asia and has been grown indoors by people, it is thought, as far back as the ancient Egyptians.

Information to get started growing cucumbers indoors in your home:

  • Choosing & Planting the seeds- What you need to know about which seeds you should pick for the best crop.
As with most indoor vegetables and fruit, it is very important to choose a variety that suits your growing environment as well as the conditions you can provide in order to get the best of the seeds that you plant. With cucumbers that is no different.Most varieties of cucumber plant grow to several feet in height. They also produce crawling vines that hoist the plant up and out (usually these are trained around a trellis).
They are also notorious for sending huge tap roots down into the soil below them.For the indoor gardener there are varieties of cucumber that are much more suited to the space typically provided by the average home.For an indoor cucumber plant you should choose a bush variety which are way more compact than the standard variety. They also require less soil and can still bear cucumbers of normal size.
You can plant these in a 7 inch pot. Just sprinkle some seeds over loosened soil and them cover them with another inch just to make sure they are covered.
Cucumber plants usually germinate within 10 days provided they have the right conditions and ‘should’ take around 60 days to fully mature.

You should aim to grow AT LEAST 2 plants for pollination purposes.

  • Light & Temperature - How to provide the correct environment for your plants to ensure growth.
In the early stages of growth, if you can provide a continuous light for the plants then do so as this will provide stimulation. If this is not possible, then provide light for as long as possible for a similar effect.
Tip – You can also provide high temperatures of around 25-30 degrees Celsius for a further boost in growth. However, this is not completely necessary!
In the latter stages, especially when fruiting, the plants will need consistent, strong light for 8 hours a day, which must need to be supplemented by a grow light if natural light will not suffice.
Note – With Cucumbers it is still possible to grow the fruit in less than optimum conditions, however you will find that the production of the plant is greatly reduced. E.g., You can also compensate for low lighting with longer periods of lighting around 16 hours.
  • Watering – Watering techniques specifically for cucumbers.
Cucumbers are very thirsty plants and will require large amounts of water especially when they begin to fruit.
Keep the soil completely moist at all times so that the plant can constantly draw water for the fruit, etc.
  • Feeding & Nutrition – How to make sure that your plants get all the nutrients that they need in order to survive and produce juicy fruits!
Cucumber plants will require feeding with a Nitrogen based plant food dissolved in water. Two feedings should carry the plant through to maturity.

  • Pollination – How to ensure that your plants are productive in their indoor environment.

Cucumber plants produce both male and female flowers. Male flowers outnumber the female flowers which can be identified by the tiny cucumbers growing behind the flower.

To pollinate your plant/s, pollen must be transferred from the male flowers to the female flowers. To do this clip a male flower off the plant and peel back the petals to use the flower as a brush. Ideally you should use males and females from alternative plants for the best results.

  • Harvesting – How to collect your fruit safely and how to maximise crop growth for the future.


Once the cucumbers reach a desirable size,
pick the fruit by cutting the stem with hand shears roughly an inch or so from the end of the fruit.
You should remove any fruit that show signs of yellowing as this can cause the entire plant to stop growth and production.
