How To Start Seeds Indoors

Starting seeds indoors is a great way to get a head start on the growing season. It also allows you to control the growing conditions, which can help to improve the success of your plants. Ace guides you step-by-step on how to start seeds indoors covering everything from germinating your seeds, to transplanting outdoors.

Step 1: Gather your supplies

You will need a seed germination kit, which typically includes a tray, a lid/dome with the ability to control humidity, and an LED. You get five of those in the Ace’s Garden Seed Germination Kit.

If you don’t have a seed germination kit, place a clear ziplock bag over your pot, grow bag or whatever you are using. This creates a warm humid climate inside allowing seeds to thrive.

Step 2: Prepare soil or other growing medium

You can start your seeds in a lot of different materials. For many people, potting soil is easy to access and usually gets the job done. Avoid potting soils with slow release nutrients.

If you don’t want to use soil you can use peat pellets, coco coir, perlite or a combination of all these growing mediums. At Ace’s Garden all of our seeds start in 100% Coco Coir before transferring to a Coco Coir-Perlite mix. Make sure you know what nutrients are in it, if any, so you can fertilize accordingly.

Step 3: Plant your seeds

To plant a seed, first make a hole in the soil that is twice as deep as the seed is wide. Then, gently place the seed in the hole and press the soil back over it. Be sure not to bury the seed too deep, as this can prevent it from germinating.

The depth of the hole is important because it allows the seed to germinate properly. If the hole is too shallow, the seed may not have enough time to develop roots before it dries out. If the hole is too deep, the seed may not be able to reach the sunlight it needs to grow.

The amount of soil you press back over the seed is also important. If you don’t press the soil back over the seed, it may be blown away by the wind. If you press the soil back too tightly, it may prevent the seed from germinating.

By following these simple steps, you can ensure that your seeds have the best chance of germinating and growing into healthy plants.

Step 4: Water your seeds

Watering seeds is an important part of gardening. Seeds need water to germinate and grow. However, it is important not to overwater seeds, as this can drown them.

To water seeds, use a watering can or hose to gently wet the soil around the seeds. Be sure not to get the seeds wet directly, as this can wash them away.

The amount of water you need to give seeds depends on the type of seed and the climate you live in. In general, seeds need to be watered when the top inch of soil is dry.

If you are planting seeds in a pot, you may need to water them more often than if you are planting them in the ground. This is because pots dry out more quickly than the ground.

By following these simple tips, you can ensure that your seeds have the water they need to germinate and grow.

Step 5: Place your seed germination kit under light

If you are using the seed germination kit from Ace’s Garden, simply plug it into a timer with a light cycling between 12-12 and 18-6. This depends on the specific need of the fruit, vegetable or flower you are growing. Leave the dome on for the first week after sprouting.

After the first week simply remove the humidity dome with LED, but do not transplant your seedlings yet. The plants need at least two weeks in the original tray to establish a root structure strong enough to sustain moving it.

If you are not using one of our seed germination kits, simply place your pot or grow bag under an LED grow light or in a sunny window. If you are using natural sunlight make sure that window gets at least 6 hours of sunlight each day.

Step 6: Keep the seedlings moist

Seedlings are delicate and need to be kept moist in order to grow properly. Here are some tips on how to keep your seedlings moist:

  • Water regularly. Seedlings need to be watered regularly, especially during hot, dry weather. Water the soil until it is moist but not soggy.
  • Use a spray bottle. A spray bottle is a great way to water seedlings without overdoing it.
  • Mulch around the seedlings. Mulch helps to keep the soil moist and cool.
  • Watch for signs of wilting. Wilting is a sign that the seedlings are not getting enough water. If you see your seedlings wilting, water them immediately.
  • Be patient. It takes time for seedlings to grow and over watering stunts your plant’s growth rate.

By following these tips, you can help your seedlings grow into healthy plants.

Step 7: Fertilize the seedlings

Fertilizing seedlings is important for their growth and development. Seedlings need nutrients to grow strong roots and leaves. The best time to fertilize seedlings is when they have their first set of true leaves.

There are many different types of fertilizers available, but it is important to choose one that is specifically designed for seedlings. Seedling fertilizers are usually water-soluble and can be diluted according to the directions on the label.

To fertilize seedlings, simply mix the fertilizer with water and pour it over the soil around the plants. Be sure not to get the fertilizer on the leaves, as this can burn them.

Fertilize seedlings every few weeks until they are transplanted into their permanent homes. Once they are transplanted, you can fertilize them less often, depending on the type of plant.

Optional Step 8: Harden off the seedlings

These last two steps say ‘optional’ but they are required if you plant to transplant outdoors.

A lot of novice green thumbs want to know why their plants always die after transplanting them. The answer is almost always due to a lack of hardening before transplanting. Knowing how to start seeds indoors only helps if you can keep your plants alive after transplanting them outdoors.

About two weeks before you plan to plant your seedlings outdoors, start hardening them off. This means gradually exposing them to outdoor conditions. Start by placing the seedlings outside for a few hours each day, and then gradually increase the amount of time they spend outside. After several days of this, if your plant still looks healthy proceed to step 9.

If your plants look unhealthy after several days of hardening, simply reduce the amount of time outdoors until it has recovered. Sometimes plants go into a state of shock when exposed to outdoor elements versus the perfect conditions indoors.

Optional Step 9: Plant your seedlings outdoors

Transplanting plants from indoors to outdoors can be a daunting task, but it is important to do it right in order to ensure the success of your plants. Here are some tips on how to transplant plants from indoors to outdoors:

Choose the right time. The best time to transplant plants from indoors to outdoors is when the weather is warm and sunny. The soil should also be moist but not soggy. Avoid transplanting during the hottest part of the day too. Morning works best.

Next you must prepare the planting site. The planting site should be in a sunny spot with well-drained soil. If the soil is not well-drained, you may need to add some sand or perlite to improve drainage. Don’t forget to water the plants thoroughly before transplanting them. This will help to prevent the roots from drying out during the transplanting process.

You are ready to dig the hole. The hole should be twice as wide as the root ball of the plant and the same depth as the pot the plant is currently in. Dig the hole and set the pot in it to get an idea of whether or not the hole is the correct size for transplant.

When it is, just remove the plant from the pot. Gently remove the plant from the pot, being careful not to damage the roots. Place the plant in the hole. Center the plant in the hole and gently backfill the hole with soil.

Water the plant. Water the plant thoroughly after transplanting it. Mulch around the plant. Mulch around the plant with a layer of straw, bark, or other organic matter. This will help to keep the soil moist and cool.

Tips for starting seeds indoors

Here are a few additional tips on how to start seeds indoors. By following this guide, your garden will thrive with fruits, vegetables and flowers.

  • Choose the right seeds. Not all seeds are created equal. Some seeds are easier to start indoors than others. Do some research to find out which seeds are best suited for your climate and growing conditions.
  • Plant the seeds at the right time. Most seeds should be planted indoors 6-8 weeks before the last frost date in your area.
  • Provide the right conditions. Seeds need the right amount of light, heat, and moisture to germinate and grow. Make sure your seed germination kit provides the right conditions for your seeds.
  • Be patient. It takes time for seeds to germinate and grow. Don’t give up if you don’t see results right away. Just keep watering and fertilizing your plants, and they will eventually start to grow.
