Baby spinach.

Harvested young, into washed salad and convenience packs

Baby spinach is spinach cut young, before the leaf coarsens, and sold washed into salad and convenience packs. The market rewards uniform small leaf and rejects anything that has started to bolt, so the commercial skill is holding the crop in a narrow window and clearing it on schedule.

What the crop needs

The crop is short-cycle and shallow-rooted. Bolting is the failure mode that decides the grade, and it is triggered by temperature and day length rather than by plant age, so climate control does more for quality here than nutrition does. The growing system itself is not settled for protected production, which is part of what this page records.

What the greenhouse has to do

Baby spinach is a narrow-window crop, and the house is built to clear it on schedule. The leaf is saleable for a short period before it coarsens or bolts, so the whole floor has to arrive together: sowing, climate and harvest are planned as one batch, and a section that runs ahead or behind is not a lower yield but a rejected pack.

The system choice is the first design decision and it drives everything after it. Growing on gutters, on moving benches or in a deep water system changes the density, the water treatment, the harvest method and the building envelope around all three. It belongs in the brief, because a house laid out for one of them does not convert cheaply into another.

DutchGreenhouses® designs the structure, climate, screening and irrigation around the leafy crop and the system chosen for it, so a narrow harvest window is cleared on schedule. Get in touch to discuss a spinach project.
