5 Things to Know About Starting Seeds Indoors

Light is the most critical factor A south-facing windowsill is rarely enough. Use a cheap LED shop light placed two inches above the seedlings for 14–16 hours per day.

Use a seed-starting mix, not garden soil Fill clean containers with drainage holes. Plant seeds at the depth listed on the packet.

Water from the bottom This prevents disturbing seeds or seedlings. Keep the soil moist but not soggy.

Cover the tray until seeds sprout A clear dome or plastic wrap traps moisture and warmth. Remove it as soon as seedlings appear.

Heat helps germination but isn’t essential A heat mat speeds things up, but a warm room works for most crops. Transplant after two sets of true leaves and suitable weather.
