Hey everyone! I'm really new to gardening and I'm trying to grow some seeds—lettuce, bell peppers, and zucchini—using an egg carton to start them off before transplanting into a raised bed in my garden. It's been two weeks, and only one lettuce seed has sprouted a tiny leaf. I've been consistent with watering. They are on my back porch, which has glass walls, so there's plenty of sunshine and it gets quite warm. I'm wondering if that's affecting my seeds. Can anyone give me beginner-friendly tips on starting seeds? Are egg cartons actually a good choice? Where should I place them? How often should I be watering them? Any advice would be appreciated! Thanks!

Honestly, starting seeds indoors isn't the easiest for beginners, and I'm surprised that your zucchini hasn't sprouted since they're usually pretty fast growers. If you can, direct sow lettuce and zucchini outdoors once the soil warms up. For bell peppers, you might want to pick up a nursery start because they take longer to grow from seed. Keep an eye on water levels too; seeds like consistency, but not saturation!
Good luck! Don't forget to check local planting calendars to know the best times for your area!
Using a heat mat can really boost your seed starting game! They're perfect for keeping the soil warm enough—just don't let the temperature go over 80°F. You'll need different timelines for different seeds, like starting peppers in early March. Lettuce can sometimes take a while to germinate, so don’t lose hope yet. Once they sprout, transition them to grow lights to avoid leggy plants stretching towards the light.
Check the seed packets! They usually explain the best conditions for germination, like the right temperature and planting depth. You might be sowing them too deeply, especially with lettuce—try to keep them about a quarter inch deep. Also, while egg cartons can work, they are kind of on the small side for seedlings. Consider using something like plastic cups for better soil depth and moisture retention.

Thanks for the tips! I’ll try sowing the zucchini and lettuce directly in the garden soon.
