--- title: "Midi Cucumbers" description: "Midi cucumber is a separate pack format with its own cultivars, fruit count and picking labour. Reference values with their Dutch sources, and what the crop asks of a greenhouse." canonical: "https://dutchgreenhouses.com/crops/cucumber/midi-cucumber" locale: "en" updated: "2026-08-11" --- # Midi Cucumbers > Part of: [Cucumber](/crops/cucumber.md) · Provider: [DutchGreenhouses](/) Midi cucumber is a shorter, lighter cucumber than the wrapped long standard, sold into retail formats suited to a smaller household portion. The type is a pack-format crop: it shares one climate recipe with long cucumber, while fruit count, harvest interval and packing line set the commercial difference. Cucumber # Midi cucumbers. Shorter than a long cucumber, and a category that has moved. Midi cucumber is a shorter, lighter fruit than the wrapped long standard, sold into retail formats that suit a smaller household portion. It occupies the middle of the cucumber range, and its commercial appeal is that it fits a pack size the long fruit cannot without being cut. ## What the crop needs The crop is grown on substrate and carried on a high wire, sharing the cucumber climate recipe with the other types. The differences that matter commercially are fruit count and harvest interval rather than climate: a smaller fruit means more picks for the same tonnage, and the labour and pack line have to be planned for the count rather than the weight. ## What the greenhouse has to do Midi is a pack-format crop, and the house is specified for the count the line expects rather than for tonnage. The climate envelope is shared with long cucumber; what changes is how often the crop is picked and how much fruit crosses the building each week. Internal transport, path width and the size of the pack area follow from that. Everything underneath is cucumber. Transpiration is high, the crop reacts within days, and irrigation and humidity control are sized for the peak. What the pack format adds is a tight size window, and even climate across the whole floor is what holds it: a section running warm or dry delivers fruit outside the window rather than fruit that is simply smaller. DutchGreenhouses® specifies the structure, climate, screening and irrigation around the cucumber type, its pack format and the local climate, so the fruit count the pack line expects is what the house delivers.

The pack is sized to be used in one go, so the fruit is eaten rather than half used and left to dry out in a fridge door. Less of it is thrown away at the end, and that is the argument for the format. The same argument runs back up the chain. A cucumber loses water from the moment it is cut, and time spent in transit and in a depot is condition spent before anyone has bought it. A format designed to cut waste in the kitchen is undone by a supply line that creates the waste earlier. Growing near the market closes that gap. The crop is picked, packed to the count the line expects and delivered inside days, and it reaches the shelf still firm, carrying the potassium and vitamin C it left the plant with. ### Nutrition facts Cucumber, with peel, raw Per 100 g Energy 15 kcal Fat 0.11 g Carbohydrate 3.63 g Sugars 1.67 g Fiber 0.5 g Protein 0.65 g Sodium 2 mg Potassium 147 mg Vitamin C 2.8 mg Source: USDA FoodData Central, FDC 168409 Questions ## Midi cucumber, asked and answered Is midi cucumber just a shorter long cucumber? Commercially no. It is a separate pack format with its own cultivars, fruit count and picking labour, even though it shares the cucumber climate recipe. What does the pack format change in the greenhouse? The handling. Fruit count per square metre is higher than for long cucumber, so picking frequency, internal transport and the pack area are dimensioned for the count rather than for the weight. Does midi need its own compartment? Not for the climate — the envelope is shared with long cucumber. The reason to split is the pick interval and the pack line, which run on different rhythms and get in each other’s way inside one space.
