Why is cucumber called the fastest crop in the glasshouse?

Fruit sets and fills in days rather than weeks, so a house can turn several crops in a year and respond to a market rather than committing to one long cycle. The same speed means a climate error shows in the grade almost immediately.

What separates the commercial cucumber types?

Fruit length and mass. Long, midi, mini and snack are pack formats with their own cultivars, fruit count, picking labour and price, sharing one cucumber climate recipe.

Why is a cucumber project specified against a named cultivar rather than a type label?

The type categories have drifted as breeding has moved, so a label alone no longer identifies a product. A named cultivar fixes fruit size, count and pack format, which is what the house, the labour plan and the pack line are dimensioned for.

Start with the end product

A crop with a market.

Greenhouse cucumber cultivation combines a selected fruit type with a trained vine, managed root zone and repeated harvesting. Product grade, available light and the crop-replacement strategy shape the operation.

The fruit the buyer wants

Agree length, weight band, shape, colour and the acceptable grade. Long, midi, mini and snack are commercial categories; their specifications can overlap between buyers.

The unit you sell

A whole fruit, counted pack and pack sold by weight place different demands on grading. Smaller fruit does not automatically mean a shorter crop cycle or more revenue per greenhouse.

The delivery programme

Define the weeks and volume the customer needs. Include establishment and crop-change gaps before turning one crop’s performance into a supply promise.

Climate and season

Start with the growing conditions.

Choose the intended harvest period and location before deciding on heating, screens, ventilation or lighting.

Light and fruit load

The canopy must support both new growth and developing fruit. Match fruit retention, stem density and pruning to season and crop vigour. A small fruit type is not permission to overload the plant.

Temperature and humidity

Temperature influences crop development; moisture and condensation affect plant health. Ventilation, heating, screens and air movement need a coordinated strategy, including during crop establishment.

Water and the root zone

Drip irrigation follows the crop, weather and substrate response. Measure supply and drainage, monitor nutrient concentration and acidity, and design collection and treatment before reusing drain water.

A greenhouse changes the growing environment; it does not remove seasonal limits.

From layout to cultivation

Put the crop into a programme.

Use the selected layout to organise the next decisions. Dates and expected harvest need a crop adviser and a location-specific plan.

Specify the plants

Agree planting material, delivery stage and the nursery programme. Reserve any on-site space before setting the production layout.

Build the canopy

Check roots, irrigation and supports; train the crop for the selected system. A planting date is not the start of saleable harvest.

Pick and renew

Prepare the next crop

Include crop removal, cleaning, system checks and replanting. Agree separate compartment programmes where supply needs continuity.

How to cultivate

Support the canopy.
Manage the roots.

The training system and root-zone system are separate choices. Match both to the crop and the people who will work with it.

High-wire training

The main stem is supported on a string and progressively lowered as it grows. Side-shoot, leaf and fruit management keep the working canopy accessible. This creates a recurring task, with crop height, support loads and safe access to resolve in the greenhouse design.

Traditional / umbrella training

In a traditional system the plant reaches the crop wire and selected laterals develop from the top. It has a different canopy and labour pattern from high-wire lowering. Select the training route for the cultivar, season and available workforce; neither route is an automatic yield or labour winner.

Drip-fed substrate on gutters

Roots grow in a substrate such as stone wool or coir. Drippers supply nutrient solution; a gutter supports the root-zone system and collects drainage. The roots do not float in the gutter. Substrate choice, slab or container volume and irrigation must be designed together.

Soil cultivation and organic production

Soil-grown crops need their own bed, drainage, soil-health and rotation plan. Trellising is still needed. Organic is a production and certification route, not a synonym for growing in soil; local requirements and permitted inputs need checking.

Fruit set, hygiene and crop changes

Commercial seedless greenhouse types are commonly parthenocarpic: they can set fruit without fertilisation. Do not copy a tomato pollination plan into this crop. Confirm the selected cultivar’s requirements, use clean planting material, scout the crop and plan cleaning between plantings.

The people and the systems

Make the daily work possible.

Match crop care, harvest and packing capacity to the growing programme.

Train and inspect

Plan regular clipping or twisting, pruning, fruit-load management and, for high wire, lowering. Access and staff skill matter as much as the support hardware.

Pick to specification

Inspect frequently and pick to the agreed size and grade. Gentle handling, grading and packing preserve quality; growing every fruit larger is not the objective.

Replace and restart

Allow time to remove the crop, clean and prepare the system, receive plants and establish the next crop. Separate compartments can support staggered programmes, with their own hygiene and climate arrangements.

Quel type de cucumber ?
Les catégories commerciales.

Récolte fréquente. Calibre régulier des fruits. La catégorie que vous vendez détermine la charge de plante, le rythme de récolte et la serre.

Long Cucumbers

Long cucumber is the classic Dutch glasshouse cucumber, sold by the piece to a tight length and straightness grade.

Midi Cucumbers

Midi cucumber is a separate pack format with its own cultivars, fruit count and picking labour.

Mini Cucumbers

Mini cucumber is picked often, and pick frequency shapes the layout of the house.

Snack Cucumbers

Snack cucumber runs a short cycle, which makes scheduling the design question.

Le concombre pousse plus vite que tout autre légume-fruit sous verre, et cette vitesse est l’argument commercial de la culture. Le fruit noue et se remplit en jours plutôt qu’en semaines, de sorte qu’une serre peut enchaîner plusieurs cultures dans l’année et suivre un marché au lieu de s’engager sur un seul cycle long. Cette même vitesse est le risque : la culture traduit une erreur de climat presque aussitôt, et il reste peu de temps pour redresser une plante bloquée ou surchargée avant que cela n’apparaisse au classement.

Ce que la culture demande

La plante est cultivée sur substrat et conduite sur fil haut, comme la tomate, mais son profil d’exigences est plus marqué. La transpiration est élevée, le fruit est essentiellement composé d’eau, et la plante avorte les charges qu’elle ne peut pas porter. La gestion de l’hygrométrie et la capacité d’irrigation pèsent donc davantage que sur une culture plus lente, et le système climatique est dimensionné pour les pointes plutôt que pour les moyennes.

Ce qui sépare les variétés

Les types commerciaux se distinguent par la longueur et la masse du fruit — long, midi, mini et snack — et ces catégories ont glissé au fil du temps, à mesure que la sélection a évolué. Une appellation seule ne suffit plus à identifier un produit, et c’est pourquoi un projet se spécifie sur un cultivar nommé plutôt que sur une catégorie. Le type détermine le format d’emballage, la main-d’œuvre de récolte et le prix, et chacun de ces éléments se planifie pour la culture réellement conduite.

DutchGreenhouses® conçoit la structure, le climat, les écrans et l’irrigation autour du type de concombre, de son cycle et du climat local, afin que la serre puisse absorber la demande de pointe de la culture et non sa moyenne. Contactez-nous pour planifier une serre à concombres.
