Great White Tomato

10 Seeds

Great White Tomato is a premium heirloom beefsteak tomato prized for its exceptionally large, creamy ivory to pale yellow fruits, often weighing 400–900 g, with some exceeding 1 kg under ideal conditions. It has a sweet, low-acid, tropical fruit-like flavor with a smooth, meaty texture and few seeds, making it excellent for fresh slicing, salads, gourmet dishes, and sandwiches. As an indeterminate variety, it produces continuously throughout the season. It performs exceptionally well in the Gulf region when grown during the cooler months and thrives in greenhouses, raised beds, large containers, and hydroponic systems.

Best Planting Time

• August to October (recommended)
• January to February (for greenhouse cultivation)
• Avoid outdoor planting when daytime temperatures consistently exceed 38–40°C.

Seed Preparation

• Soak seeds in warm water (25–28°C) for 6–8 hours before sowing (optional).
• No cold stratification is required.

Soil Preparation

Use fertile, loose, well-drained soil rich in organic matter.

Recommended mix:

• 40% Coco peat
• 30% Compost
• 20% Garden soil
• 10% Perlite

Ideal soil pH

• 6.0–6.8

Sowing Method

• Sow seeds in seed trays or nursery pots.
• Plant seeds 0.5 cm deep.
• Cover lightly with fine soil or vermiculite.
• Keep the growing medium consistently moist until germination.

Temperature & Light

• Ideal germination temperature: 21–29°C
• Ideal growing temperature: 20–30°C
• Requires 6–8 hours of direct sunlight daily.
• During very hot Gulf afternoons, provide 30% shade cloth.

Watering

• Keep the soil evenly moist during germination.
• Water deeply when the top 2–3 cm of soil becomes dry.
• Water at the base of the plant and avoid wetting the foliage.

Germination Time

• 7–14 days

Transplanting

Transplant seedlings when they have:

• 4–6 true leaves
• Height of 15–20 cm

Space plants:

• 60–75 cm apart

Space rows:

• 90–120 cm apart

Harvesting

Harvest begins:

• 80–90 days after transplanting

Harvest regularly to encourage continuous production.

Gulf Climate Tips

• Plant during August to October for the highest productivity.
• Support plants with sturdy stakes, tomato cages, or trellises, as this is an indeterminate variety that produces very large, heavy fruits.
• Remove lower leaves and excessive side shoots to improve airflow and reduce disease pressure.
• Fertilize every 2 weeks with a balanced fertilizer, then switch to one higher in potassium and phosphorus during flowering and fruiting.
• Apply organic mulch to conserve moisture and reduce soil temperature.
• Because of the exceptionally large fruit size, provide strong support for both the main stem and fruit clusters.
• Great White Tomato performs exceptionally well in greenhouses, hydroponic systems, raised beds, and large containers.
