Cucumbers in greenhouses
Fast-cycling and high-volume — greenhouse cucumbers are one of the most productive crops, with multiple crop cycles per year and strong, steady retail demand across four commercial types.
Four types, from foodservice to snacking
GrowPro greenhouses support the full range of greenhouse cucumbers on high-wire hydroponic systems:
- Long (English) cucumbers — the classic supermarket cucumber and the volume workhorse of the category, with the highest yield per m² of the four types.
- Midi cucumbers — a versatile mid-size for retail and foodservice, balancing volume with convenient packaging formats.
- Mini cucumbers — crisp single-serve size for lunchboxes and fresh-cut programs, sold at a premium per kilo.
- Snack cucumbers — the smallest format and the strongest margin position, competing in the snacking category alongside cherry tomatoes.
Indicative yields
Derived from GrowPro model yield data (hydroponic cultivation; second figure with growlights):
| Type | Yield | With growlights |
|---|---|---|
| Long | ≈ 52 kg/m²/yr | ≈ 97 kg/m²/yr |
| Midi | ≈ 38 kg/m²/yr | ≈ 68 kg/m²/yr |
| Mini | ≈ 14 kg/m²/yr | ≈ 29 kg/m²/yr |
| Snack | ≈ 8 kg/m²/yr | ≈ 16 kg/m²/yr |
Actual results depend on climate, variety and cultivation strategy.
Nutritional value (per 100 g)
Light, hydrating and consistent — greenhouse cultivation keeps cucumber quality stable across every cycle. Indicative values per 100 g:
| Type | Calories | Vitamin C | Vitamin A | Potassium |
|---|---|---|---|---|
| Long | 15 kcal | 2.8 mg | 105 IU | 147 mg |
| Midi | 15 kcal | 3.0 mg | 110 IU | 150 mg |
| Mini | 16 kcal | 3.2 mg | 115 IU | 152 mg |
| Snack | 16 kcal | 3.5 mg | 120 IU | 155 mg |
Greenhouse configuration
Cucumbers reward generous light and stable humidity: high-wire training keeps fruit straight and clean, and consistent irrigation and fertigation drives the fast cycling that makes the crop profitable. The Expert series handles cucumber production up to 2 acres; the Plus series adds the air volume and optional HortiCoolers that keep summer production stable in warmer climates. Labor is moderate, with frequent harvesting through each cycle.
Frequently asked questions
How many crop cycles per year do greenhouse cucumbers have?
Typically two to three cycles per year depending on climate, lighting and crop planning — one reason cucumbers reach such high annual volumes.
Which cucumber type is best for my market?
Long cucumbers for supermarket volume, midi for versatile retail formats, mini and snack for premium single-serve and snacking programs.
What yields can I expect?
Long cucumbers reach roughly 52 kg/m²/year in a GrowPro greenhouse without lights and around double that with growlights; smaller formats trade volume for higher prices per kilo.
Which greenhouse model fits cucumber production?
GrowPro Expert up to 2 acres; GrowPro Plus for larger operations, warmer climates (optional HortiCoolers) or lit winter production.
