Cucumber
Long Cucumbers.
The wrapped Dutch standard, and the fastest crop in the house.
The end product
Long cucumber for your market.
Agree the length and weight band together. Straightness, colour and freedom from surface defects matter to a whole-fruit retail programme.
Specify the saleable fruit
A full-length fruit with a consistent shelf specification.
Cultivation consequence
Plan for fruit length through the crop: support and canopy work should leave space for developing fruit and avoid handling damage. Match fruit retention to the light and crop strength.
Length grading and handling
A long fruit needs room in harvesting containers and packing lines. Decide whether it is sold loose or individually wrapped, then check the handling route and buyer specification.
How to cultivate
Connect the fruit to the system.
Plan for fruit length through the crop: support and canopy work should leave space for developing fruit and avoid handling damage. Match fruit retention to the light and crop strength.
Drip-fed substrate
Manage the roots in a selected substrate, with irrigation, drainage and a crop-support system. Choose the canopy arrangement separately.
Soil-based cultivation
Use a bed and root-zone plan suited to the site, crop history and irrigation. Organic production requires its own applicable certification assessment.
Climate and crop work
Review the season, canopy, fruit load and harvest grade together. High-wire lowering and traditional training create different work patterns.
Long cucumber is the classic Dutch glasshouse cucumber, shipped shrink-wrapped to hold moisture in a fruit that is almost entirely water. It is sold by the piece to a tight length and straightness specification, so a fruit outside the grade has little value regardless of its weight. It is the primary Dutch long high-wire baseline.
What the crop needs
The plant is grown on substrate and carried on a high wire, and it moves fast: fruit fills in days, and the plant will abort a load it cannot support. Transpiration is high, so irrigation capacity and humidity control are sized for peaks rather than averages. Because the crop responds within days, climate faults are expressed almost immediately — which makes the crop unforgiving, and also makes it quick to diagnose.
What the greenhouse has to do
Cucumber pushes the climate system harder than tomato does. Transpiration is high and the crop answers within days, so irrigation capacity, humidity control and ventilation are sized for peak demand rather than for the seasonal average. A house dimensioned on averages runs out of headroom in exactly the weeks that decide the grade.
Cycle planning is a design input, not an operational detail. The crop is fast enough to run more than one planting in a year, and how many the house runs sets the heating profile, the lighting decision and the labour pattern together. Length and straightness are graded fruit by fruit, so even transmission and even water delivery across the whole floor are worth more than a strong specification at one point in the house.
DutchGreenhouses® specifies the structure, climate, screening and irrigation around the cucumber crop, its cycle and the local climate, so peak demand is carried and fruit holds the grade. Get in touch to plan a cucumber greenhouse.
Long cucumber, asked and answered
Why is cucumber considered a demanding crop to climate-control?
It grows and fruits faster than other fruiting vegetables, so an error in humidity or irrigation shows within days and there is little time to correct it before it reaches the grade.
How many crops a year can a cucumber house run?
It depends on the cycle chosen, the lighting and the market being supplied. The crop is fast enough to allow several, which is why cycle planning is a design input rather than an operational detail.
Why is the fruit wrapped?
To slow water loss. The fruit is largely water and loses condition quickly once picked, so wrapping protects shelf life rather than appearance alone.
