Are you a helicopter parent? (No, we’re not shaming you, we promise). But if you’re a gardener who wants complete control of the growing process, from start to finish, then starting seeds indoors is the way to go.

Starting seeds indoors holds value for seeds and gardeners alike. Gardeners in colder climates can extend their growing season considerably by starting heat-loving crops like tomatoes and peppers indoors, weeks before these seeds would germinate naturally. Vegetable, herb, and flower seeds all benefit from being started indoors—with the proper schedule and equipment, you can expect your first harvest weeks and months before a direct-sown garden.

Starting seeds indoors does require some finesse—you don’t want to start seeds too early, or your plants will be flowering and fruiting before their growing season has even begun. There are also a few more pieces of equipment required for starting seeds indoors—you’ll need seed-starting soil mix, seed-starting trays, and likely heat mats, humidity domes, and even grow lights for the best results.

You don’t have to start seeds in a greenhouse—we don’t all have that luxury, after all. Seeds are just as happy to sprout in a garage or a closet, so long as you still provide your seed trays with lighting, warmth, water, and proper ventilation.

To start seeds indoors, you’ll want to fill each seed-starting tray with moist—not soaking—soilless growing mix. You can use either peat moss or a more sustainable alternative, like coco coir. Use a 50- or 72-cell tray for most vegetables, and use 128- or 200-cell trays for smaller seeds like herbs and flowers. Sow at least two seeds together for large seeds, and three or four for tiny seeds. A good rule of (green) thumb is to sow seeds twice as deep as they are big. Cover the seeds lightly with another layer or growing medium, and gently water them in with a watering can or wand on the lightest setting.

Be patient—germinating seeds does take some time. And while no seed has a perfect germination rate, you can trust that Eden Brothers’ seeds are 100% pure seed, with no additives or fillers, always non-GMO. If you follow the sowing instructions available online and printed on the packet, you will see fantastic results, and soon.
