Homemade Greenhouse

What You Need:

  • A tray of grass or growing seeds
  • A jar

Instructions:

  1. Place the jar over a patch of grass or a section of your plant tray of seeds.
  2. Watch the plants under the jar grow taller and faster than the ones outside.

Why?

The jar creates a greenhouse, which provides a warmer and moister atmosphere for growing plants. The light and heat from the sun go through the glass and heat the air inside, and the heat cannot escape very easily.
