Cucumber
- Recommended tray
- 128 – 200 cells
- Days to germination
- 3 – 6 days
- Optimal temperature
- 25 – 30 °C
Key care pointFast, even emergence; watch excess moisture to prevent seed-tray disease.
Crops
Guide by crop: cucumber, pepper, chili, tomato, eggplant and Asian greens
A reference for seedling production by crop, based on standard protected-agriculture practice in Sinaloa, to help you plan your next cycle with less uncertainty.
The values below are regional references. The exact protocol is adjusted by variety, cycle and greenhouse conditions.
Bell Pepper
- Recommended tray
- 128 – 200 cells (25 – 45 cm³)
- Days to germination
- 7 – 14 days
- Optimal temperature
- 25 – 30 °C
Key care pointAvoid very small cells: they produce weak seedlings and tangled roots, delaying crop establishment.
Hot Peppers
- Recommended tray
- 200 – 242 cells
- Days to germination
- 8 – 14 days
- Optimal temperature
- 25 – 30 °C
Key care pointSlower to germinate than bell pepper; keep steady warmth and moisture until emergence.
Tomato
- Recommended tray
- 128 – 200 cells
- Days to germination
- 5 – 8 days
- Optimal temperature
- 24 – 28 °C
Key care pointVery vigorous; manage light well to avoid leggy, stretched seedlings before transplant.
Eggplant
- Recommended tray
- 128 – 200 cells
- Days to germination
- 8 – 14 days
- Optimal temperature
- 25 – 30 °C
Key care pointSlow to germinate; needs steady warmth and patience in the seed tray.
Asian Greens
- Recommended tray
- 242 – 288 cells
- Days to germination
- 3 – 5 days
- Optimal temperature
- 20 – 25 °C
Key care pointShort cycle and high density; small seed that benefits from a larger cell per plant.
Seed-tray best practices
How a uniform seedling is cared for
- 01
Dark room the first days
Trays are covered and moved into darkness to even out germination, uncovering them as soon as the first shoots emerge.
- 02
Gentle irrigation, controlled pH
Overhead or micro-sprinkler irrigation so the seedling isn't damaged, with irrigation water at a pH between 5.5 and 6.5.
- 03
Greenhouse biosecurity
Footwear and hand disinfection on entry and humidity control to prevent seed-tray diseases such as damping-off.
- 04
Trays disinfected between cycles
Trays are reusable and disinfected between cycles as part of crop-protection management.
