HomeGrowingBest Containers for Microgreens: Choosing the Perfect Homes

The best containers for growing microgreens are shallow plastic trays with drainage holes. These trays provide the perfect environment for microgreens to thrive. The shallow depth allows for the roots to spread out and access water easily without becoming waterlogged, while the drainage holes prevent excess water buildup and prevent root rot. Additionally, plastic trays are lightweight, affordable, and easy to clean, making them a practical choice for growing microgreens at home. With the right container, you can create an ideal growing environment for your microgreens and ensure their successful development.

Benefits of Growing Microgreens in Plastic Trays

Growing microgreens in plastic trays offers many benefits, from easy draining to space-saving convenience. Plastic trays are perfect for growing microgreens as they keep the soil contained and provide ample drainage. These trays can be used both indoors and outdoors, allowing you to grow your own fresh greens regardless of the weather outside.

Moreover, because they come in a variety of sizes and shapes, you can find one that will fit perfectly into your setup — whether it’s an aeroponic or hydroponic system. Using shallow plastic trays with drainage holes is ideal for microgreens as it allows excess water to escape without disturbing the roots. Furthermore, these trays are lightweight and easy to move around when needed, which is great if you want to change up your setup often or take them with you on vacation.

Additionally, since these containers can be stacked atop each other or placed side-by-side in tight spaces, they offer tremendous space savings compared to larger grow beds or hydroponic systems. The most important benefit of using plastic trays for microgreen growing is that they allow air circulation around the plants’ roots while still keeping them moist enough for germination and growth.

This combination helps ensure that your microgreens have access to all the necessary nutrients without becoming dry and stunted due to lack of oxygenation at their root zone. Additionally, this type of tray also allows for greater control over temperature fluctuations which can help prevent heat stress during hotter months or cold damage during colder months — optimal conditions that lead to healthier crops year round!

Finally, because these trays are relatively inexpensive and widely available online or in stores near you, getting started with growing microgreens has never been easier! Plus, with a wide range of colors available — such as clear, green, blue, purple, black, white, pink, yellow, and orange — you can customize your tray setup according to aesthetics too! All this makes shallow plastic trays with drainage holes an excellent container choice for anyone looking to start a successful microgreen garden at home.

Choosing the Right Trays

When it comes to choosing the right trays for growing microgreens, size and number of drainage holes are two key points to consider.

You’ll want the tray to be shallow enough so that your microgreens don’t become too root-bound, yet large enough to provide adequate space between plants.

Additionally, you’ll want to make sure there are enough drainage holes in the tray so that excess water can seep out while still keeping the soil surface moist.


Smaller trays provide the optimal size for microgreens, allowing them to grow in close quarters just like a bustling city street.

The ideal container size for microgreens is usually between 4-6 inches deep, and 8-10 inches wide. This allows the plants enough room to establish their roots without overcrowding each other.

Tray depth should be shallow enough that the soil doesn’t become too compacted when watered; otherwise, it will impede drainage and cause anaerobic conditions which can stunt growth.

It’s also important to make sure that the tray has plenty of drainage holes so any excess water can properly escape while still retaining enough moisture in the soil for healthy plant growth.

Shallow plastic trays with drainage holes are ideal for microgreens, as they provide a cost-effective way to promote better yields from your crop.

Number of Drainage Holes

By having the right number of drainage holes, plants can receive the necessary water to grow while avoiding anaerobic conditions that can stunt their growth. The number of drainage holes needed will depend on the watering frequency and the soil depth within the container.

If you are planting in a shallow plastic tray with a thin layer of soil, then more drainage holes may be necessary so that excess moisture does not build up and cause stunted growth. On the other hand, if you are using a deeper pot with more soil, fewer drainage holes may be required since it will take longer for moisture to accumulate before causing issues.

Therefore, it’s important to consider both your watering frequency and soil depth when deciding how many drainage holes should be in each container for growing microgreens.

When selecting containers for microgreens, shallow plastic trays with adequate drainage holes are ideal. This allows roots to spread out easily and access oxygen from all sides as well as ensuring proper moisture levels at all times.

Too few or too many drainage holes could lead to overwatering or underwatering respectively, which can have negative effects on plant health and crop yields. Properly spaced drainage holes also ensure sufficient aeration and prevent stagnation of water, which can lead to anaerobic conditions that stunt root growth and cause disease in plants.

Preparing the Tray for Growing

Preparing a shallow plastic tray with drainage holes for microgreens is like building a fortress to protect them from any potential harm. First, choose the right seed selection for your microgreens. Look for varieties that germinate quickly and don’t require too much attention while growing.

Make sure you have enough space in the trays to accommodate the number of seeds you plan on planting. Then, fill your trays with pre-moistened potting soil or special medium designed specifically for microgreens. Make sure you use only clean tools when handling the soil and avoid over-packing it as this can impede proper drainage.

The next step is to sow your seeds evenly across the top of the soil surface and lightly press them into place with your hands or a tool like a dibber. If using multiple kinds of seeds, make sure they are kept separate so they can be easily distinguished once they start sprouting.

After sowing, cover the tray with another layer of potting soil or medium to ensure even germination and give an even appearance after harvesting. Finally, water regularly using gentle watering methods such as misting or bottom watering so as not to disturb newly planted seeds before they have had a chance to take root properly in their new environment.

While there may be many other ways to prepare shallow plastic trays with drainage holes for microgreens, following these steps will help ensure that your plants get off to an optimal start and enjoy healthy growth throughout their lifecycle while also protecting them from any potential harm during cultivation.

With careful preparation and maintenance of your microgreen containers, you can look forward to enjoying delicious greens all year round!

Planting the Seeds

Once your tray is ready, it’s time to start planting the seeds! The first step is selecting the right soil. Make sure you’re using a light and airy soil that has good drainage capabilities. It should also be able to hold moisture without becoming too soggy or waterlogged. Additionally, make sure there aren’t any contaminants in the soil such as pathogens or fertilizers that could damage your microgreens.

Next, it’s important to understand the light requirements for your chosen type of microgreen. Generally speaking, most types of microgreens need at least 8-10 hours of sunlight per day, with some requiring even more depending on the species you choose. If you don’t have access to natural sunlight, consider investing in grow lights so that your plants can get enough energy from artificial sources.

Thirdly, you’ll need to pay attention to how deep you plant each seed into the soil. This varies by type but usually ranges between 1/8th and 1/4th inch below the surface of the soil. Planting too shallow can cause uneven growth and problems with root development, while planting too deep can result in poor germination rates and wilting seedlings.

Finally, once all of your seeds are planted in their designated locations, be sure to lightly mist them with water until they become moist but not overly saturated. This helps ensure that all of your seeds have equal access to water during germination, which is essential for healthy growth patterns in young plants.

Caring for the Microgreens

To ensure healthy growth of your microgreens, it’s essential to provide them with proper care and attention; in fact, research has found that up to 90% of microgreen seeds can fail if not properly cared for.

When caring for microgreens, one of the most important things to consider is selecting the right soil. It should be lightweight and well-draining, such as a soilless mix or vermiculite. For optimal results, you should also make sure to add some organic matter like compost or aged manure to your soil mix. Additionally, avoid using any type of chemical fertilizer as this can harm the delicate plants.

The second step in caring for your microgreens is providing them with adequate water. You want to keep the soil evenly moist but not saturated; this means watering every few days or when the top layer begins to feel dry. The best way to water is from below by placing a shallow tray filled with water underneath the pots and allowing it soak up naturally through drainage holes in the bottom – this method prevents overwatering and helps reduce mold growth on top of soil. Additionally, try misting your plants with a spray bottle every few days so they stay hydrated without becoming soggy and vulnerable to disease.

When selecting containers for growing your microgreens, shallow plastic trays with drainage holes are ideal because they allow excess moisture to evaporate quickly while still maintaining enough humidity levels for optimal plant growth. These trays also provide plenty of space for roots and ensure that all parts of the plant receive an equal amount of light exposure which further aids its development. Additionally, make sure you are using clean containers as bacteria can accumulate over time leading to diseases that could kill off your crop before harvest time arrives!

Finally, remember that monitoring temperature levels is crucial when caring for microgreens – too much heat can cause them to wilt while cold temperatures may stunt their growth altogether! To prevent either situation from occurring, use a fan or small air conditioner depending on where you live – both will help circulate fresh air throughout your indoor garden which will benefit both you and your beloved greens!
