Fast-Growing Indoor Plants for a Winter Science Project

Fast-Growing Indoor Plants for a Winter Science Project

A student needs plants that grow indoors in two months during winter for an electric shock experiment.

Suitable Plants

With a bright window or grow lights, these can mature in 8–10 weeks:

• Dwarf sunflowers (e.g., 'Sunspot', 'Teddy Bear')
• Baby's breath (Gypsophila elegans)
• Low-growing cosmos (e.g., 'Sonata' series)
• Marigolds or pot marigolds (Calendula)
• Lettuce (leaf types, 30–45 days)
• Radishes (30+ days, need deep container)

Growing Tips

• Use 12–14 hours of fluorescent light (5000–6500K) if window light is weak.
• Keep temperatures 65–75°F.
• Use well-draining potting mix and fertilize lightly.
• Label and track each treatment group carefully.

Radishes and lettuce are fastest and easiest to measure.
