One Dirt Bag, which is enough seed-starting soil to generously fill your Sixie 15 times. That's up to 90 plants with one kit! (That comes out to $0.65 per plant, btw, and you'll still have the pot to last for a lifetime of seedlings and growing your own.)
3 Packets of our favorite beginner-friendly seeds. The exact seed type may vary, depending on availability and seasonality, but all will be edible (even if they're flowers!) and forgiving to grow.
