A seed worth growing
A generative tomato rootstock.
Estamino is a strong generative rootstock that sends a high share of its energy to fruit, so plants are easier to keep in balance.
Especially useful for crops grown under six months, in unheated tunnels, or with small-fruited varieties under about 100 g. For rootstock use only.
For grafting only: sow to match the scion variety. F1 hybrid.

Know before you sow
Growing times vary with weather, soil and local conditions.
Time sowings so rootstock and scion graft at the same diameter.
Germination can be uneven; graft the best seedlings.
Start near EC 1.0, pH 5.8, and raise it as plants grow.
73–77°F for a few days, then cooler nights once fruit sets.
Solanum lycopersicum
A rootstock is grown only to be grafted: its vigorous, disease-resistant roots carry a fruiting variety (the scion) that you choose. Fruit quality comes from the scion.
Sow rootstock and scion so the stems match in diameter at grafting time; top (splice) grafting and side grafting both work. Some rootstocks sprout unevenly, so sow extra seed and pick the best-matched seedlings.
Once the seed leaves have opened, feed with a complete nutrient solution (around EC 1.0, pH 5.8) as needed to keep seedlings dark green, raising the EC as they grow. After the grafts heal, grow plants on as usual.
Grow seedlings at about 66–68°F (19–20°C) day and night. For a few days after planting into the greenhouse, hold 73–77°F (23–25°C) to push roots and leaves; once fruit sets, aim for 68–72°F (20–22°C) by day and 62–66°F (17–19°C) at night.
