Welcome to the

Mini Greenhouse

Gardening is a great way to teach your little one(s) so many different things! It can teach them about plants and help them understand what plants need to grow and live. It can also be a lesson in patience and responsibility. Today we are going to show you how to create your very own miniature greenhouse using two plastic cups! This activity is a great opportunity to reuse plastic cups, which fits in perfectly with our “Reduce Reuse Recycle” Kids Night In Box.


  • Colored plastic cup
  • Clear plastic cup (needs to be a little bigger than colored cup)
  • Pushpin
  • Seeds
  • Water
  • Plotting soil


  1. First, use the push pin to poke a few holes in the bottom of your colored plastic cup.
  2. Fill your colored plastic cup 3/4 of the way full with soil. Be sure to pat the soil down!
  3. Place up to 5 seeds in your soil and be sure to space them out. Cover these seeds with one more scoop of soil and pat it down again.
  4. Give your seeds a LITTLE bit of water.
  5. Place your clear plastic cup upside down, on top of the colored plastic cup. Then place your greenhouse somewhere it will receive lots of light.
  6. Finally, be sure to keep a close eye on your plants and to care for them properly. They will need a little bit of water each day, but remember don’t over water them. Pretty soon you will begin to see sprouts growing!
