Sowing Vegetable Seeds in Home Environments
Gear up gardening folks! Winter's still got its icy grip, but spring's right around the corner. Now's the perfect time to prepare for the next growing season by starting your vegetable seeds indoors!
No need to limit yourself to seed-starting within your house; an enclosed environment tailored to your specific seed is the way to go.
Why Start Seeds Indoors?
It all comes down to our short growing season. By seeding indoors, we extend the season, sowing young plants that can be later transplanted into the garden once the right weather hits.
Growing plants from seeds offers endless fun. Watching a tiny seed sprout into a vibrant plant that can replicate itself is just mind-blowing. Plus, it saves you some cash. With little effort, you can cultivate many seedlings for a fraction of the cost compared to buying one plant.
Perfect Growing Conditions for Seeds
Remember the spring starting seed schedule we talked about? You've got two options when it comes to starting your seeds indoors – add more time (seed early) or create a better growing environment for fast seed germination and growth. We opt for the latter. Let's dial in the optimal conditions for any given plant variety:
But wait! Don't put your seedlings in a broiling hot oven. A warm and sunny location is what these little guys really crave.
When to Start Seeds Indoors
No need to rush starting seeds too early. Pampering seedlings for months isn't necessary; they grow much faster when they get a taste of natural sunlight and warmth later in the season. If you just can't wait for spring, check out some great alternatives to growing seedlings.
What You Need for Seed Starting
Pots
Seed-starting pots can be found in various shapes and sizes. Go green and build your own pots from newspapers! Fancy something different? Try a soil block maker. On a budget? Opt for peat moss pots, but just keep in mind our dry climate may not be a perfect match for those.
Pot sizes vary depending on how long the plants will grow inside. We like using small, recyclable planters for plants that spend minimal time indoors (cabbage, onions, etc.). Yogurt containers work wonders for peppers and tomatoes, while toilet paper tubes secretly double as cucumber planters (the roots can be plunked directly into the ground without disturbing them).
For larger plants like squash, go for a bigger pot. Or, try out the bottomless pot method to save transplanting work.
Propagation seed starter trays are perfect for starting plants like lettuce, chard, and beets.
Soil
Choose light soil for seed-starting. A special seed starting mix or sterilized soil may be essential for some small seeds, but most vegetables don't require anything fancy.
Mel's Mix from the Square Foot Garden book is our fave soil blend. It consists of equal parts compost or warmcasting, vermiculite, and peat moss. Find these ingredients at a garden center or Home Depot and mix them together.

Labels
Labeling is crucial for keeping the different seedlings organized. Use garden labels, spoons, or even wooden labels. However you label them, just make sure you remember what you're growing.
A handy garden notebook helps too. See our post on making your own garden notebook for inspiration.
Heat Mat
Warm temperatures are crucial for seed germination. Find a warm spot in your home, like the top of a fridge. If you need more warmth, a Germination Station with a Heat Mat might do the trick.
After germinating, some seedlings prefer cooler temperatures; winter crops, like cabbage family plants, thrive in a sunny basement window or out in the garage greenhouse.
Grow Lights
Once the seedlings pop up, they require ample light. If starting seeds earlier in the season, you might need grow lights to provide adequate illumination. But if possible, use a south-facing window since grow lights are more like a cloudy day compared to direct sunlight.
If natural light isn't sufficient or spring is mostly cool and overcast, you may need to incorporate grow lights. T5 lights work well as supplementary lights, while LED lights are more energy-efficient. North windows are a no-go for seedlings.
How to Sow Seeds Indoors
- Fill a container with soil, compacting it slightly. Ensure the container is filled without air pockets but isn't too compacted. Make sure the soil is moist before planting the seeds.
- Plant seeds no more than 3 times their size deep. Larger seeds can be planted even more shallowly. Cover peas and beans, but most other seeds can be planted shallower.
- Plant 1-3 seeds for plants that grow best alone. Once sprouted, thin the seedlings to have just one plant per pot.
- After the seeds are planted, water them in. For smaller seeds, use a mister; for larger seeds, use a small watering can.
- If you're in a dry climate, cover the pots with plastic wrap to conserve moisture.
That's it! Sit back, relax, and watch your seeds transform into healthy seedlings.

In preparation for the growing season, start your seeds indoors in an enclosed environment that fosters optimal growth for your specific plant varieties. This helps extend the season, allowing you to transplant young plants into the garden once weather permits.
Growing plants from seeds is a rewarding DIY experience that offers endless fun and saves you money. With little effort, you can cultivate many seedlings for a fraction of the cost compared to buying one plant.
When starting seeds indoors, choose suitable pots, soil, seeds, labels, and either a heat mat or a warm location in your home. A south-facing window or grow lights may be necessary to provide ample light for seedlings when starting earlier in the season.
To start seeds indoors, fill a container with light soil, plant seeds no more than 3 times their size deep, water them in, and cover pots with plastic wrap if in a dry climate. Be patient as you watch your seeds transform into healthy seedlings.
