The fruit shares the blocky four-lobed form, the yellow colour is genetic, and buyers treat the colour as a distinct product assembled into mixed packs from separate crops. Sweet pepper # Yellow bell peppers. A separate genotype class, not a shade of red. Yellow bell pepper is its own genotype class with its own cultivars, not a red pepper picked at a different moment. The fruit form is the same blocky four-lobed shape that defines the block-pepper category, and the yellow colour is genetic. Buyers treat the colours as distinct products, and mixed-colour packs are assembled from separate crops rather than sorted out of one. ## What the crop needs The plant is long-cycle on substrate and high wire, sharing the block-pepper climate and structural reference. As with every ripe-coloured pepper, the fruit occupies the plant until it colours, so the season is planned around ripening time rather than around reaching full size. Steady climate over weeks is what keeps the set continuous. ## What the greenhouse has to do Colour class changes the schedule the house has to hold, not the envelope it provides. Each class ripens on its own timetable, and a house running mixed colours is running several schedules under one climate. Compartment layout and the pack plan carry that, because a climate cannot be tuned in two directions at once. The rest is block-pepper building. The structure supports a long-cycle plant on a high wire, the heating and screening design is set against the colouring period rather than the setting period, and irrigation is sized for the peak. Colour uniformity inside the pack is what the buyer inspects, so evenness across the whole floor decides how much of the crop reaches the top grade. DutchGreenhouses® specifies the structure, climate, screening and irrigation around the pepper crop, its colour class and the local climate, so ripening holds to the schedule the pack expects.

It is its own genotype ripened to its own colour, and it eats differently: milder than green, and carrying more vitamin C by weight than either the red or the green. A mixed punnet is several crops, not one crop sorted by colour. That is also why the colours are grown apart. Each ripens on its own schedule and occupies the plant for as long as its own colour takes, and a house running a mix is running several harvest plans under one climate. Ripeness is again what the journey takes. A yellow pepper is cut finished, so distance subtracts from the shelf rather than adding to the fruit. Growing near the market lets each colour be picked when the pack needs it, so a mixed punnet is filled with fruit of the same age instead of fruit that left on different days. ### Nutrition facts Sweet pepper, yellow, raw Per 100 g Energy 27 kcal Fat 0.21 g Carbohydrate 6.32 g Fiber 0.9 g Protein 1 g Sodium 2 mg Potassium 212 mg Vitamin C 183.5 mg Source: USDA FoodData Central, FDC 169383 Questions ## Yellow bell pepper, asked and answered Does yellow need a different house from red? No. The structure and the climate envelope are shared across the block-pepper colours. What differs is the ripening schedule, and that shows up in compartment planning and the pack plan rather than in the specification of the building. Why grow a mix of colours? Mixed packs are a retail format, and they are assembled from separate crops. Each colour is planned, grown and picked as its own crop. Does yellow ripen at the same rate as red? Ripening time is a cultivar property and differs by class. It is one of the inputs that sets the harvest plan, which is why colours are planned as separate crops rather than as one crop picked at different stages.
