I feel like this is one of the most hassle free things I ever do in my garden. For plants like greens, root crops, even melons and cucumbers I've had better luck with seeding outside than with transplanting. Additionally, this cuts out a lot of seedling maintenance that is required for other things like tomatoes and most herbs.
I direct seeded some beets, radishes, and turnips just 3 weeks ago and look at them now.
I feel like a lot of people that I talk with are intimidated by growing carrots. I once felt this way also, but after trial and error here's my system:
|Furrow, seeds, measuring device, potting soil mixed with horticultural sand, 2X4 scrap|
Easy, right? Lastly, make a note somewhere of when you started these because inevitably you are going to have a moment in 2 weeks where you say to yourself, "this didn't work" even worse, you might go ahead and turn the bed up and plant something else. Carrots take anywhere from 10-21 days to germinate depending on your climate and the seeds, so have patience.
I guarantee its worth the wait, homegrown carrots are so tasty.
