Indoor Cherry Tomato Bud Problems

Growing a cherry tomato indoors near Chicago: plant is 1 meter tall but buds are small, yellowing, and not flowering. What's wrong?

Indoor Tomato Challenges

Tomatoes are difficult indoors. Key questions: What temperature? Light type/duration? Are these first buds? Yellow buds may actually be opening flowers—tomato flowers don't grow larger once open.

Critical Needs

• Consistent 70-80°F temperatures.
• Strong light (14+ hours daily, fluorescent within 3-4 inches).
• Pollination assistance (shake plant or use brush).

Without these, fruit set will be poor.
