Idea 1

Germination greenhouse

Easy 15 min

Growers and gardeners have always used mini greenhouses to get seedlings started ahead of the right planting season. The moisture retained inside the cup creates a microclimate that keeps the seed from drying out before sprouting — the heat stays trapped and germination speeds up.

What you need

  • 1 or 2 disposable cups (ideally one transparent)
  • Soil or light substrate
  • Seeds (lettuce, arugula, tomato, beans)
  • Water in a spray bottle
  • Scissors or a toothpick to pierce

How to make it

  1. 1

    Make 3 or 4 small holes in the bottom of the cup, because excess water needs to escape so the roots don't rot.

  2. 2

    Fill with soil almost to the rim, moisten with the spray bottle and bury the seeds at the depth indicated on the packet (general rule: twice the size of the seed).

  3. 3

    Cover the cup with a second cup turned upside down, forming a dome — if you only have one cup, use plastic wrap held with a rubber band.

  4. 4

    Leave it in a bright spot but out of direct sunlight, because inside the greenhouse strong sun would cook the little seeds.

  5. 5

    Open the lid a few minutes a day to refresh the air and spray water when the soil is drying to the touch.

Finishing touches

when the seedlings touch the "lid," it's time to transplant them into a larger pot. Write the seed name and the date on the side of the cup with a permanent marker to keep track of each variety.
