You’ve gathered your supplies, personalized it all to make it unique and
beautiful, and you’re ready to start. Here we go!
STEP 1
Fill a large bowl with seed-starting mix and mix in a little water to evenly
moisten the soil. You might want to wear a face mask because this soil is very
fine and can irritate your airways.
STEP 2
Place your seed tray inside the drip tray and fill each cell to just below the top
with soil.
STEP 3
Sow your seeds. If the seeds are tiny, like lettuce or arugula seeds, sprinkle
just a few of them over the soil; if they’re larger, like pumpkin, or nasturtium
seeds, you can push 2 seeds into the soil in each cell (one is a backup in case
one doesn’t germinate). Sprinkle a little more soil over the top to cover the
seeds and mist until the surface is damp.
A good rule of thumb is to plant the seed to the same depth as its thickness.
For example, lettuce seeds need only a tiny sprinkling of soil to cover them
but a nasturtium should be covered with about 1/4” of soil.
STEP 4
Cover the tray and place it under your lights on the heat mat. Don’t forget your
plant labels!
