Step 2: The Cup – Planting the Seed in the Cup
Here’s how:
Fill the cup with potting soil, leaving a half-inch of space at the top.
Poke a little hole in the soil (about a half inch deep) and slip the seed in. The pointed end of the seed should go up and the rounded end go down.
Sprinkle seeds with a fine layer of soil and tamp lightly. Don’t cram it in too tightly, though — you want there to be a little air in there for the seed.

Step 3: Add Water and Cover the Cup
Water the soil lightly after you planted. You don’t want to drown it — just enough to get the soil moist.
To keep the seed warm and humid, cover the top of the cup with plastic wrap or a small clear plastic bag. This produces a mini greenhouse effect, which is exactly what you want for growing seeds. I prefer to poke a couple of small holes in the plastic for ventilation.
