DIY Mini Greenhouse Kit

4 Materials
1 Hour

Make this easy mini greenhouse to start seeds indoors. This is a very easy DIY project that's great for kids or adults. It uses upcycled materials, so it can even been completely free to make.

You can use this for vegetable seeds or flower seeds. I use it for tomatoes, peppers, zucchini, and lettuce in mini greenhouses inside and then move them to the garden when they are bigger.

You'll need:

  • clear plastic containers (I used a spinach container, but you can use a strawberry container)
  • Seed starting mix
  • 18 paper rolls
  • Craft sticks
  • Spoon
  • Scissors
  • Sharpie


Cut the paper towel rolls to they will fit inside the container with the lid closed. Leave room to make a bottom for each roll so the dirt stays in the roll. Make four 3/4 inch cuts on the bottom.


Fold the flaps over to seal.


Set the rolls inside the container. Fill the rolls with seed starting mix.


Cut the sticks in half and label.


Place the seeds in the dirt. Follow the directions for each type of seed for the proper depth.

Set your mini greenhouse in a warm location until the seeds germinate into sprouts. Then place where they will get sunlight. The paper rolls are biodegradable, so you can plant them directly in the ground.

    Does anyone know how this holds up to watering before you plant them into the ground?

      But the cups defeats the purpose of using the paper, you don't have to remind the seedings from the tubes to plant them, the tubes will break down in the garden

    Where did you get that small trowel?

      You can use forks and spoons that you find in a thrift store or yard sale.

    Found plants were quite stunted when planted in the garden, the roots weren't getting through the cardboard unless the ground was saturated, took them out of the tubes and they flourished

    Just now

    Rolls got moldy before I could plant them, just as seeds were emerging!
