Why Deep Seed Starting Trays Are Necessary

I’ve been starting seeds indoors for years, and I’ve tried a variety of different methods. I’ve used shallow seed starting trays, deep seed starting trays, and even egg cartons. After a lot of trial and error, I’ve come to the that deep seed starting trays are the best way to go.

There are a few reasons why I prefer deep seed starting trays. First, they allow for more root growth. When seedlings have more room to grow their roots, they are stronger and more resilient. This means that they are less likely to transplant shock when you move them outdoors.

Second, deep seed starting trays help to prevent damping off. Damping off is a fungal disease that can kill seedlings. It is caused by a combination of factors, including poor air circulation and moisture. Deep seed starting trays allow for better air circulation, which helps to prevent damping off.

Finally, deep seed starting trays make it easier to transplant seedlings. When you transplant seedlings, you want to disturb their roots as little as possible. Deep seed starting trays make it easier to transplant seedlings because you can simply pop them out of the tray and into the ground.

If you’re looking for the best way to start seeds indoors, I highly recommend using deep seed starting trays. They will give you healthier seedlings that are less likely to transplant shock or get damping off.

Here are some specific benefits of using deep seed starting trays:

  • More root growth: Deep seed starting trays allow for more root growth, which results in stronger and more resilient seedlings.
  • Prevention of damping off: Deep seed starting trays help to prevent damping off, a fungal disease that can kill seedlings.
  • Easy transplanting: Deep seed starting trays make it easier to transplant seedlings because you can simply pop them out of the tray and into the ground.

    My Buying Guides on ‘Deep Seed Starting Trays’

Deep seed starting trays are a great way to start your own seedlings at home. They provide a structured and organized environment for your seeds to germinate and grow, and they can help you save money on gardening supplies. In this buying guide, I will discuss the different types of deep seed starting trays available, as well as the factors you should consider when choosing one.

Types of Deep Seed Starting Trays

There are two main types of deep seed starting trays: plastic and biodegradable. Plastic trays are the most common type, and they are typically made from recycled materials. Biodegradable trays are made from materials that will break down over time, such as peat moss or coconut coir.

Plastic trays are generally more durable than biodegradable trays, and they can be reused for multiple seasons. However, biodegradable trays are more environmentally friendly, and they can be composted after use.

Factors to Consider When Choosing a Deep Seed Starting Tray

When choosing a deep seed starting tray, there are a few factors you should consider:

  • Size: The size of the tray will depend on the number of seeds you plan to start. Most trays come in a variety of sizes, from small 12-cell trays to large 100-cell trays.
  • Depth: The depth of the tray will determine how deep your seeds can be planted. Deeper trays are better for seedlings that require more space to grow, such as tomatoes and peppers.
  • Drainage: The tray should have drainage holes to allow excess water to drain away. This will help to prevent your seedlings from drowning.
  • Material: The material of the tray will affect its durability and environmental impact. Plastic trays are more durable, but biodegradable trays are more environmentally friendly.

How to Use a Deep Seed Starting Tray

Using a deep seed starting tray is simple. Just follow these steps:

1. Fill the tray with seed starting mix.
2. Sow your seeds according to the package directions.
3. Cover the seeds with a thin layer of seed starting mix.
4. Mist the seeds with water.
5. Place the tray in a warm, sunny location.
6. Keep the soil moist until the seedlings emerge.
7. Once the seedlings have emerged, thin them out so that they have enough space to grow.
8. Continue to water and fertilize the seedlings as needed.
9. When the seedlings are ready to transplant, carefully remove them from the tray and transplant them into your garden.

Deep seed starting trays are a great way to start your own seedlings at home. They are easy to use and provide a structured and organized environment for your seeds to germinate and grow. By following the tips in this buying guide, you can choose the right deep seed starting tray for your needs and successfully start your own seedlings.
