ORNAMENTAL
Cut flowers under protection
Rose, gerbera, chrysanthemum and lisianthus: light-hungry, pest-sensitive, and sold on stem quality rather than weight.
Flower crops tolerate higher humidity than fruit but need more air movement to hold quality and suppress botrytis.
A rose house is a five-year asset: design for the second and third crop cycle, not only the first.
Climate range and crop notes
| Day temperature | 20–26 °C |
| Night temperature | 15–18 °C |
| Humidity | 65–80 % RH, strong air movement |
| Light | High; supplementary light common in winter |
| EC / pH | 1.8–2.4 mS/cm, pH 5.5–6.2 |
| Cycle | Perennial houses, 3–5 year cycles for rose |
General horticultural ranges for a well-managed crop; local variety, light and market specification move these values. Not a yield guarantee.
First-season mistakes that cost the most
- Ignoring pest-vector screening in a rose house.
- Under-investing in post-harvest cold room and grading space.
