Microgreens Trays vs. Seedling Germination Trays

Definition of Seedling Germination Trays

Seedling germination trays are specialized containers designed for starting seeds indoors or in a greenhouse. These trays come in various sizes and shapes and are usually made of plastic or other durable materials. 

The primary purpose of germination trays is to provide a stable and controlled environment for the seeds to sprout and grow into healthy seedlings. 

The trays are typically filled with a growing medium, such as soil or a soilless mix, and have multiple small cells or compartments where individual seeds can be planted. The trays also help to keep the growing medium moist and prevent it from drying out, which is crucial for successful seed germination. 

Some seedling germination trays come with holes in the bottom to allow for drainage, while others do not. Overall, these trays play a vital role in the early stages of plant growth, ensuring that the seedlings get the best possible start before they are transplanted into larger containers or directly into the garden.

Differences Between Microgreens Trays and Seedling Germination Trays

Microgreens trays and seedling germination trays are often used interchangeably, but there are some key differences between them.

Seedling germination trays are designed to help sprout and grow seeds into seedlings. These trays are typically deeper than microgreens trays and are filled with soil or other growing media to support the growth of the seedlings. Seedling germination trays are also often covered with a plastic dome or lid to create a warm and humid environment that encourages germination [2].

On the other hand, microgreens trays are shallower and are specifically designed for growing microgreens. Unlike seedling germination trays, microgreens trays are not covered with a plastic dome or lid. 

Instead, they are typically grown in an open environment, allowing for better air circulation and reducing the risk of mold growth. Additionally, microgreens trays are often made from sturdier plastic than seedling germination trays, allowing them to withstand repeated use [3].

Another key difference between microgreens trays and seedling germination trays is the growing medium used. While seedling germination trays are typically filled with soil or other growing media, microgreens can be grown in a variety of different mediums, including soil, coco coir, and hydroponic growing mats [1].

In summary, while both microgreens trays and seedling germination trays can be used for starting plants from seeds, they are designed for different purposes. 

Seedling germination trays are deeper and used for growing seedlings, while microgreens trays are shallower and specifically designed for growing microgreens. Additionally, microgreens trays are often made from sturdier plastic and can be grown in a variety of different growing mediums.

Reusability of Microgreens Trays

Microgreens are young plants that are harvested just after they have sprouted and before they have reached maturity. They are packed with nutrients and have gained popularity as a superfood in recent years. 

One way to grow microgreens is by using microgreen trays, which have many benefits over other methods of microgreen production. One such benefit is that microgreen trays require a reduced volume of growing media compared to traditional methods, such as using pots or garden beds [1]. This makes them a more sustainable and cost-effective option.

Another benefit of using microgreen trays is their sturdiness. Unlike flimsy plastic trays or pots that can easily tip over and damage delicate young plants, microgreen trays are specifically designed to support the growth of microgreens. 

The sturdy construction of microgreen trays provides the necessary support to prevent soil and seed displacement during watering, moving, or transplanting, which is important to ensure the healthy and successful growth of microgreens.

Lastly, microgreen trays are reusable, making them a more environmentally-friendly option. These trays can be washed and sterilized after each harvest, then reused for subsequent microgreen batches. 

This not only reduces waste but also makes microgreen production more sustainable and cost-effective in the long run. Overall, using microgreen trays for microgreen production has many benefits, including the reduced volume of growing media needed, sturdiness of the trays, and reusability.

Reduced Volume of Growing Media Needed

Reducing the volume of growing media required for plant growth is an important aspect of container gardening. According to a resource from Cornell University, the proper growing medium must provide adequate water supply, gas exchange, mineral nutrients, and plant support [1]. 

Adding topsoil to large containers can increase the volume and should not exceed 5-10% of the total volume, as per a resource from the University of Maryland Extension [2]. Additionally, growing media can be reused to save money, but it is important to remove all plant residues and tags and store the media in a clean, dry container [2].

In general, field soils are not suitable for container gardening, and the growing media must be amended to provide the necessary physical and chemical properties for plant growth, as noted by the Texas A&M AgriLife Extension Service [3]. 

Therefore, by using microgreen trays for microgreen production, growers can reduce the volume of growing media needed while still providing the necessary conditions for plant growth, resulting in more efficient use of resources and potential cost savings.

Factors to Consider when Choosing Microgreens Trays

The first factor to consider is the material of the tray. Microgreens trays can be made of plastic, metal, or even biodegradable materials. 

Plastic trays are the most common and affordable option, but they may not be as environmentally friendly as biodegradable options. Metal trays are more durable and can last longer, but they may be more expensive.

Biodegradable trays are a great option for those looking for an environmentally friendly option, but they may not be as sturdy as plastic or metal trays.

The size of the tray is another important factor to consider. The size of the tray will depend on the number of microgreens you want to grow and the available space you have for your growing area. Larger trays can hold more microgreens, but they may require more growing media and take up more space.

Smaller trays may be easier to handle and require less growing media, but they may limit the number of microgreens you can grow at once.

The depth of the tray is also important. Microgreens typically only require a shallow growing depth, so trays that are too deep may not be efficient for growing microgreens. 

However, the depth of the tray may depend on the type of microgreen being grown, as some varieties may require deeper growing depths than others.

The design of the tray is another factor to consider. Some trays may have drainage holes for excess water, while others may not. Trays with drainage holes can help prevent overwatering and ensure proper air circulation, but they may require more attention to watering. 

Trays without drainage holes may be easier to maintain but may require careful monitoring to prevent overwatering.

Finally, the cost of the tray is an important factor to consider. Trays can range in price depending on the material, size, and design. While it may be tempting to choose the most affordable option, it is important to consider the long-term cost and durability of the tray.

In summary, when choosing microgreens trays, it is important to consider the material, size, depth, design, and cost. By carefully considering these factors, you can choose the best tray for your specific needs and ensure successful and efficient microgreens growth.

Tips for Using Microgreens Trays

When it comes to using microgreens trays, proper planting techniques are crucial for successful and healthy growth. Here are some tips to keep in mind when planting your microgreens:

Use a high-quality growing medium: The growing medium should be free from pathogens and pests and have a good water-holding capacity to promote proper growth.

Moisturize the growing medium: Before planting the microgreens, moisten the growing medium thoroughly. This will help to ensure that the seeds are properly hydrated and that they have access to the moisture they need to germinate.

Seed density: The seed density should be such that the microgreens have enough space to grow without being overcrowded. Overcrowding can lead to stunted growth and an increased risk of disease.

Light exposure: Microgreens need sufficient light exposure to grow properly. Place the microgreens trays in a location that receives adequate sunlight or use artificial lighting if necessary.

Watering: Water the microgreens regularly, ensuring that the growing medium is consistently moist but not waterlogged.

Harvesting: Harvest the microgreens at the right time, depending on the variety. Microgreens are typically ready to harvest within 1-3 weeks of planting.

By following these tips and using proper planting techniques, you can ensure the healthy growth of your microgreens and enjoy a bountiful harvest.

Recommended Growing Media for Microgreens

Growing media play a crucial role in the success of microgreen production, as they provide a stable environment for seeds to germinate and grow. There are many types of growing media available, including soil, peat, coco coir, vermiculite, and perlite, among others. 

However, not all growing media are suitable for microgreens production. The ideal growing media for microgreens should have a good water-holding capacity, provide adequate drainage, and contain the necessary nutrients for seed germination and plant growth.

One popular growing media for microgreens is a soilless mix. Soilless mixes typically consist of peat moss, vermiculite, and perlite, which provide good drainage and water-holding capacity. Soilless mixes are also sterile, reducing the risk of disease and pests, and can be easily customized by adding nutrients, such as compost or fertilizer. 

Coco coir, a byproduct of coconut processing, is another popular soilless growing media for microgreens, as it is renewable, sustainable, and has excellent water retention properties.

Another option for growing microgreens is to use hydroponic growing media, such as rockwool or coconut coir mats. Hydroponic growing media are sterile and provide excellent water and nutrient uptake. However, they require specialized equipment and careful management to maintain the appropriate pH and nutrient levels.

Ultimately, the choice of growing media will depend on the availability, cost, and desired level of sustainability. When selecting a growing media, it is important to consider its water-holding capacity, drainage, nutrient content, sterility, and sustainability. 

It is also important to source high-quality growing media from reputable suppliers to ensure the best possible results in microgreen production.

Proper Planting Techniques

Proper planting techniques are crucial for successful microgreens production. When planting in trays, it is important to pre-moisten the growing media before planting. This ensures that the seeds have sufficient moisture to germinate. 

The amount of growing media used in the tray should also be appropriate for the seed size and the desired thickness of the microgreens. The growing media should be evenly spread in the tray and gently pressed down to ensure good seed-to-soil contact.

Seeds should be evenly distributed across the tray to avoid overcrowding, which can lead to poor growth and an increased risk of disease. A good rule of thumb is to sprinkle the seeds on the surface of the growing media at a rate of about one seed per square inch. 

After the seeds have been sown, they should be lightly covered with a thin layer of growing media to prevent them from drying out and to provide some protection against pests.

Once the seeds have been planted, it is important to keep them moist by misting them with water or using a bottom watering method. The trays should be covered with a clear plastic lid or plastic wrap to create a humid environment that promotes germination.

After the seeds have germinated and the first set of true leaves have emerged, the cover can be removed to promote air circulation and prevent mold growth.

Finally, it is important to monitor the microgreens as they grow to ensure that they are getting enough water, light, and nutrients. The growing media should be kept moist but not waterlogged, and the microgreens should be exposed to bright, indirect sunlight or artificial light sources for several hours each day. 

As the microgreens mature, they can be harvested by cutting them at the base of the stem, just above the growing media.
