Starting your own plants from seeds is one of the most rewarding parts of gardening. Whether you’re eating something you grew or watching a hummingbird buzz around your flowers, it’s truly amazing to think about it all starting with a tiny seed. Plus, it’s incredibly inexpensive to grow from seeds. You can seriously save hundreds of dollars each year by learning how to start your own seeds successfully.

Not only will it save you money, but it’ll also give you a huge head start for the growing season. By starting your seeds indoors or in a greenhouse instead of the ground, you’ll have strong, healthy plants ready to go once the risk of frost has passed. Seed starting isn’t rocket science, but you can give yourself an extra advantage by having the right supplies.

What to Look for in a Seed Starting Kit

Pot Material

When growing plants from seeds, try to create a sustainable system by either using pots that are biodegradable or pots that can you can use year after year. If you do use plastic pots, make sure they are BPA free and of food grade if you plan to start your own veggie seeds.


Does your kit come with lighting? If so, does it have timed lighting? Are there instructions about how much lighting to use, how long to use it, and other details? While you can find information online about starting seeds, you can tell a lot about the quality of a kit, depending on what kind of information is included on things like lighting. This is true for the lights itself as well. Read about the wattage, how frequently you might need to change it, and other details to make sure you’re choosing your investment wisely.


All pots, planters, and even seed-starting kits need to have proper drainage. Without this, you run the risk of getting moldy seeds or drowning your little seedlings. It’s a must—not just a nice to have.

Frequently Asked Questions

  • When should you start your seeds?

    This depends a lot on where you live, what the temperatures are, and where you’ll be growing your plants. If you’re just starting seeds for the purpose of growing inside or on a windowsill, you can experiment with seed starting year-round. But if you’re trying to grow seeds ahead of spring or summer, you definitely want to get the timing right. The general rule of thumb is you want to start seeds about six weeks before you expect the last frost, but there are other factors to consider as well. If possible, join a local garden group in your area. Local gardeners will be extremely valuable in helping advise you.

  • How much water do I need?

    When you’re first watering seeds, it’s best to start light. You might even use a spoon to help you avoid disturbing the seeds as they’re trying to get established. You basically want to add more water when the top layer of the soil is dry to touch. It’s a simple test but effective for keeping a good system.

  • How much sun do I need?

    Budding seedlings needs as much as 10-14 hours of sunlight per day to really get established. This is going to be challenging for most people, so many need to supplement with grow lights. If your seed kit doesn’t include grow lights, you’ll definitely want to consider adding some because they can make a big difference in your overall success.

  • How many seeds do I need?

    Figure out how many plants you want to grow, and then double or triple that number in seeds. You never really know how many seeds you’ll lose until you get into the season. Often, gardeners will grow several seeds in one pod, then thin them out to leave the strongest ones. It usually doesn’t cost much more to grow a few more seeds, and you’ll definitely be glad you did. Then if you have extra, pass them on to a gardening friend!

  • Does it really save money?

    Definitely! Growing plants from seeds is one of the best ways to save money when it comes to gardening. If you can get the process down, you can seriously save hundreds and even thousands of dollars on plants. After you master the basics like herbs and veggies, then try to move on to more difficult seed-starting plants like perennials and shrubs. It’s so satisfying and incredibly resourceful.

More Seed Starting Resources

If you’ve tried seed starting in the past without much luck, don’t be afraid to try again. Often, the failures can be narrowed down to just a couple of main issues: Not enough light (the plants become “leggy”) or too much water (they don’t need much).

For all the basics on how to start seeds indoors, start with this article. You can also learn about damping off, another main concern, and how to avoid it here. You might want to start with seeds that are easier than others like the examples in this article. It’s definitely worth the effort to figure out how to get it right.
