Premixed, soil-less material can be bought in nurseries and stores. These mixes are economical when used carefully. Any type container can be used from egg cartons to milk cartons. The seeds could care less if they are planted in an old tin can or a solid gold pot. Regardless of the starting method, the gardener should allow proper space for each plant to develop.
Crowded seedlings become leggy and unhealthy.
Soil temperature is important. Cool soil retards germination. Warm the soil to about 75 degrees if possible until seedlings have emerged. Provide an air temperature of 70 to 75 degrees during the day and nighttime temperatures of about 60 to 65 degrees. Cover the seed only enough to make it disappear from view.
