Germinate Seeds with Humidity

Some seeds can only be germinated in a humid environment. This article will show you how to germinate seeds in a humid environment and also provide special tips on which seeds need humidity or don't.


Researching About the Seeds

  1. Look for the temperature the seeds need to germinate. Basil, bell peppers, papaya and strawberries are examples of seeds that need humidity to sprout. Leafy greens like lettuce need constant moisture to sprout.
    • For example, bell peppers only germinate at around 70 degrees.
  2. See if the plant seeds are native to a humid place.
    • Seeds like papaya are tropical and native to places such as Mexico and South America.
  3. Research the seeds prefers growing conditions.
    • Some seeds, such as lettuce, need moist soil to germinate.
    • Certain seeds require constant moisture for germination.

Creating the Perfect Environment

  1. Use a container big enough to fit all the seeds.
  2. Lay one to two paper towels in the bottom of the container. Pour in about 1 inch (2.5cm) of water, or until damp to the touch.
  3. Place the seeds on the paper towels in the containers.
    • Make sure they are evenly spaced, to prevent crowding
    • Make sure the seeds are not touching each other or overlapping
  4. Close the lid. Place the seeds in a constantly warm environment.
    • Place a plug in heat pad under the container.
  5. Provide light almost 24/7. Place the container with seeds in an area that receives the most sunlight.
    • Use a grow light to provide direct sunlight during the day, if the indoor area is too dark.
  6. Change the paper towels when it has a smell or brownish colors appear.
    • Remember to add also add water when changing the paper towels.
    • Only change the paper towels when no roots have sprouted.

Preparing For Transplanting

  1. With the perfect humid environment provided, the seedlings should emerge after around 5 days. Wait for the second pair of leaves to appear before doing anything.
    • Length of time for emergence will depend on the seed type; some seeds may take longer.
  2. Remove the lid once the third pair of leaves have emerged.
    • If the seedlings look healthy, then keep the soil moist and the lid off to get the seedlings use to air without humidity.
    • Leave the lid on if the seedlings fall over or show signs of unhappiness.
  3. Cut around the seedlings with their own part of the paper towel. This helps to safely transfer the seedlings without harming or damaging the roots. The paper towel will decompose with the soil naturally.


  • In the proper humid environment, seeds will actually germinate faster.
  • If the seeds do not germinate, try adding more heat/warmth.
