Cover them at night to keep the moisture in, but make certain they are exposed to lots of sunlight and fresh air throughout the day. TRANSFER to individual seed containers as the last step – fill the segments with starter soil and gently place the little plants into the mixture – they can remain here until they are planted outside when the weather is warm and free from frost.
Using PERLITE as the second medium of growth was simply an option – It was chosen as an experiment for gently moving the baby seedlings, and it worked. Going straight to the starter soil (skip the perlite) avoids transplanting twice. HAPPY GROWING!!
