How to Sow Seeds Indoors

Things You'll Need:

• Plant Light
• Potting Soil
• Seed-starting Medium
• Seeds
• Vermiculite
• Containers
• Plastic Bags
• Plastic bags
• Seeds

1. Step1

   Consider your timing. Some plants need to be planted as much as 12 weeks before your region's last average frost date, while others do best when started just two weeks before.

2. Step2
   

   Choose your seed-starting container. Nearly any container with drainage will do, but good candidates include milk carton bottoms, egg cartons, plastic produce boxes, peat pots and special seed-starting flats. (Punch drain holes into containers that need them.)

3. Step3
   

   Plant seeds in sterile seed starting mix. It has no soil to cause disease problems and is lightweight - perfect for baby plants to get off to a good start. Sprinkle vermiculite over seeds that require covering. Its lighter color helps you see just what you've covered.

4. Step4

   Follow seed package directions about the depth of planting. As a rough rule, the larger the seed, the deeper it's planted. Some very small seeds are just scattered directly on the soil and not covered up at all.

5. Step5

   Water gently. Either set the container in 1 to 2 inches of warm water and allow the water to wick up to the soil surface, water gently from above with a special bulb-type hand sprinkler, or dribble water from your hand.

6. Step6
   

   Slip the container into a clear plastic bag to minimize drafts and conserve moisture. Twist the end shut.

7. Step7

   Put the seeds in a spot with the correct temperature. (Check the seed packet.) Keep the seeds out of direct sunlight or risk fatally overheating them. Seeds usually need either cool temperatures of 50 to 65 degrees F or warm temperatures of 70 to 85 degrees F. Find an especially warm or cool spot by checking with a thermometer in different locations in your house.

8. Step8

   Check the seeds daily. If water drops form inside the bag, open the end to vent it. Once the seeds germinate, remove the plastic and put the seedlings in the brightest indoor spot possible.

9. Step9

   Put the new seedlings in a sunny, unobstructed south-facing window. Or set them a few inches below a shop light equipped with one warm and one cool fluorescent light. Use an inexpensive light timer to automatically keep the lights on 14 to 16 hours a day
