Start 10-12 weeks before planting date. Sow seeds densely into trays ¼” apart. Transplant 6” deep when 10-16” tall. Leaves only need to be 2-4″ above soil. 1/2″ 7-29°C Prepare a clean, loose, well-drained growing medium and moisten it before placing the seeds so they are not displaced by the first watering. Keep the seedbed evenly moist without standing water because excess moisture reduces air around developing roots. Move seedlings into bright light as soon as they emerge and rotate containers regularly to encourage balanced growth. Where several seedlings compete for the same space, thin carefully and retain the strongest plants without disturbing their roots. Use the product details as a clear guide on how to start seeds while keeping the growing medium evenly moist, never saturated.

Harvest at any stage but flavour is best in fall after a few cold nights. Carrot, Onion, Celery, Garlic, Beets, Cabbage, Spinach, Lettuce, Tomato. The packet contains 100 seeds.
