- Sauce + Canning: Paste tomatoes (lower water content, rich, meaty flesh like Roma or San Marzano).

🌱 Quick Growing Tips (Canada)
- Start early: Sow indoors 6–8 weeks before the last frost; germinate at 22–25 °C.
- Light matters: 14–16 h/day under bright LEDs; keep lamps close to the canopy to prevent leggy growth.
- Transplant: Plant out only after nights stay consistently above 10–12 °C; harden off for 7–10 days.
- Soil & feed: Use a nutrient-rich, airy mix (compost/coco/perlite). Use balanced fertilizer early, then bump Potassium (K) for fruiting.
- Pollination: Tomatoes are self-pollinating; gently tap flower clusters weekly to improve fruit set.
