Starting From Seeds - Growing Indoor Plants With Seeds

Last Updated On: July 7, 2021

One of the most exciting aspects of gardening is start from seeds and slowly turning them into a full, healthy plant. There’s something very inspiring about going from nothing to something. If you’ve only grown from seedlings before, starting from seeds may seem a bit difficult. But, have no fear, today we’ll look at some tips to help you grow thriving plants in your own home starting from the smallest seed.

The Container

Unlike full grown plants, seeds don’t need as much room to grow therefore giving you more options for their containers. Their root systems are shallow which allows many non-traditional containers to be used.

Almost any sort of containers will do. Everything from old egg cartons, to pie tins, or even traditional planters will work. You can even start with a growing kit, which provide multiple small areas to plant your seeds. The only hard requirement is that the chosen container has proper drainage. A few holes in the bottom is enough to allow water to drain.

The other important thing to keep in mind is to make sure your container is clean. This is especially true if you reuse and older container or use one that’s been left outdoors. Seeds and seedlings are very susceptible to pests and infections; unclean pots can easily spread this. This is most important if the pot was used outdoors, but it doesn’t hurt to give it a quick once over even if it wasn’t.

In many cases, gardeners will start with a seed growing container and then transplant their plants once they begin to grow leaves. This is our recommended way to start as it makes it easy to manage the specific needs of your seeds and seedlings. You can always start in their final container as well, and this will work fine if the proper care is followed.

The Soil

Seedlings are very delicate, so it’s important to choose the right growing medium. Using a specific seedling mix is best, but any light soil will do. The key is to not use a medium that is too thick or heavy as the weak roots will have trouble spreading out in it.

You also want to avoid using any existing soil, whether that’s left over in your containers or taken directly from the outdoors. As noted above, seeds are susceptive to pests and disease and using old soil increases this risk.


One of the most important aspects to growing seeds/seedlings is having ample light. Without enough light you’re likely to end up feeble looking plants that grow and produce poorly.

Put your plants in a large south facing window to expose them to the most light. If that’s not enough, setting up a few grow lights will work until the plants mature.

If using lights, you’ll want to keep them 3-4 inches above the plant. This means you’ll have to move them as the plants grow in order to promote proper growth. Also, this means using fluorescent bulbs is a no go as the heat at that range will damage the plant.

Keep in mind, that during the winter the sun is less intense in seasonal areas. If you’re starting seeds in the dead of winter natural light is even less likely to be enough and you’ll have to resort to grow lights.


Before the seeds actually sprout, they will like a bit of extra warmth than a typical plant would. Many gardeners therefore place their grow containers on top of the dryer, refrigerator, or a few inches above a heating vent. You don’t want to bake them, but raising the temperature a few degrees will help encourage them to sprout.


Watering seeds is a bit different than a full grown plant. Firstly, in the seed stage you don’t have to water at all. The key is to moisten the water before planting, and then cover the container with plastic to hold in the humidity. This will create an ideal environment for your plants, and the prevent water from dislodging or disrupting the plants.

You can also opt to water in a normal fashion by simply keeping the soil moist. In most cases, you’ll want to pre-moisten the soil, then give the soil a light misting each day. This keeps the soil moist while avoiding flooding the soil and potentially dislodging the seeds.

One the seeds begin to sprout remove the plastic (if applicable) and begin watering to keep the soil moist (but not drenched). As seedlings are still very weak a good technique is to water from the bottom. The soil will actually wick up the water, and if done correctly will provide enough for your plant to grow. This once again prevents any damage that might occur from watering weak plants.

Read The Packet

Lastly, make sure to read the packet before sowing your seeds. Generally, the packet will have care information on the back that includes seeding and growing instructions. This includes things like how deep you should place the seed, and how far apart seeds should be placed. These factors are very important to growing healthy seedlings so take a few minutes to read over it before planting.

Some packets might also have information on growing instructions after it’s sprouted or suggestions on when to transplant or harvest. If you’re not familiar with the plan you’re growing it’s a good idea to keep these tips on hand to help speed along healthy growth.

When To Plant Seeds?

Timing is important, and is influenced by your end goal for the plant. If you’re growing indoors then anytime is a good time to start. The spring/summer may be a bit easier due to the increased light, but with careful care even the winter will be fine.

If you plan to move or start outside then you need to keep your environment in mind. Ideally, you want to ensure that you’ll transplant after your areas last from date. It generally takes about 2-3 weeks for a plant to be ready to transplant so make sure that lines up with frost dates.

Starting From Seeds

Starting from seeds is a great journey that every gardener should experience. There’s just something special about starting from something so small and growing it into a thriving plant.

Common Issues

Only Some Of My Seeds Germinated?

There are many causes as why this happened when starting from seeds, but is often due to overwatering. Dig into the soil and find a seed, if it’s mushy that means the soil was too damp and the seed has rotted.

My Seedlings Are Weak and Spindly?

The most common cause for this is lack of light. Make sure your plants are getting enough light and rotate them every few days to ensure it’s received evenly.

My Seedlings Suddenly Died?

This is most often caused by soil fungus or bacteria that is collectively called [damping off],in%20wet%20and%20cool%20conditions.). There’s nothing that can be done after the fact, but starting with fresh soil and a clean container greatly reduces the risk.
