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.
Advantages of Using Microgreens Trays for Microgreen Production
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.

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.
