What is Microgreens Trays？

The benefits of growing microgreens are that they can be grown all year anywhere you live. The reason is that they can be easily grown indoors, in greenhouses or other protective arrangements. With the right temperatures, airflow, light, and supplies you are set for success.
As you start growing microgreens selecting the right Microgreens Trays can be a challenge as there are so many options and many of them look the same. Do I need one with holes or without, or even both, what are the advantages, how deep should it be, with a transparent cover or blackout dome?

Benefits of Microgreens Trays

Durability

The Microgreens Trays must be durable enough to withstand daily use for many years, meaning they should not break or crack in case of accidental dropping or hitting a hard surface.

Strength

You need to have enough strength to lift a tray filled with moist soil from one end, no matter how small or large it is. It is possible that you may have to take one hand off the tray in case you stumble, hurt your toe, or need to catch something else that is falling. Therefore, the tray should be sturdy enough to bear its weight without bending or breaking.

Low Height to Soil Volume Ratio

Using shallow Microgreens Trays is better than using deep Microgreens Trays because deep Microgreens Trays require more soil to fill and can cause issues during blackouts, reduce light to young microgreens, and make harvesting difficult. Microgreens can grow in very little soil, so deep Microgreens Trays are unnecessary. To avoid these problems, it is recommended to fill Microgreens Trays with soil levels near the top.

Evenly Spaced & Reasonably Sized Holes

Planting Microgreens Trays should have multiple evenly spaced holes that are big enough to allow water to pass through but not too big that soil falls through when bottom watering. The holes should be present around the tray perimeter and throughout the bottom surface.

Bottom Ridges or Tight Fit

To prevent overwatering, watering Microgreens Trays should have either ridge on the bottom or a tight fit. Ridges elevate the planting tray, allowing for the drainage of excess water. A tight fit forces water higher into the soil and prevent one-time overwatering.

Type of Microgreens Trays

Planting Tray
This tray or container must contain bottom holes that allow extra water to drain and are large enough to uptake water into the soil media when dry.
The hole spacing should be even across the bottom with a reasonable diameter that allows some soil media to come in contact with the water but not so large that it falls out. Media with strands work best, like coconut coir and peat moss.
Microgreens grow better in trays that exclude light from the roots. So transparent or opaque trays aren’t as good as dark or black trays. We aren’t sure why; maybe the roots sense light and don’t grow toward the trays’ edges.

Watering Tray
A watering tray must be larger than the planting tray or allow the planting tray to slide into it. The watering tray must be solid to hold water with sides high enough not to let water flow over when the planting trays are placed into the watering tray.
Also, a useful watering tray has ridges (ridges can be on the bottom of the planting tray) that keep the planting tray elevated. This allows extra water to drain out and away from the soil media. Flat bottom watering & planting trays work, but not as well.

1010 Shallow Microgreen Trays
1010 shallow trays are square, with each side being a little under 10-inches on the inside of the tray and the outside dimension being a little over 10-inches. The height of these trays is 1-1/4 inches.
These are very practical-size trays for most people, even those with two or more people eating microgreens in the house.

Common Problems With Microgreens Trays

Micro greens are really easy to grow with the right soil, light & watering.
Too much soil & shade & a choice of seed that could have done with a soak before sowing. If only I’d gone with my own advice & picked radish!

Slow germination – Depending on the seed, most Microgreens Trays germinate within a few days. If this doesn’t happen, ensure seeds aren’t exposed. Microgreens need a period of darkness to germinate, so make sure they’re all covered by a thin layer of soil. Another way to speed up germination is to pre-soak the seeds before sowing. Larger seeds in particular benefit from soaking, as it helps to soften their outer shell.

Mould or mildew – If you notice mould or mildew growing on your Microgreens Trays, the soil is likely too wet, or there’s too much humidity or insufficient drainage in the soil or tray.

Wilting greens – If your micro greens are looking a bit lacklustre & wilting it’s most likely they need more water.

Uneven growth or leaning greens – Uneven growth is often down to too many seeds clumped together, whilst leaning greens is often a result of unequal light distribution. Seeds will always grow in the direction of the light source, so if some are in shade, for example, these are likely to grow at an angle towards the direct light. Try rotating the tray or use artificial grow lights to provide a more even distribution of light.

Yellow microgreens – It’s completely normal for Microgreens Trays to look yellow at first. This is because the chlorophyll in the leaves hasn’t yet carried out photosynthesis. As soon as leaves receive enough light they should turn green. However, if they continue to look yellow, it’s probably due to over watering or insufficient light.

How To Microgreens Trays Step By Step

An easy, step by step tutorial on how to microgreens trays. Includes instructions, what you’ll need, as well as tips on how to use microgreens, details on the different types & nutritional benefits.
Microgreens are also really easy (and quick) to grow. So, if like me, you’re prone to scrutinising every thing you plant for signs of immediate growth, you won’t have to wait long. Their quick growth also means you can easily generate a constant supply if you plant a batch of seeds every week or so.

Step 1

Fill your seed trays with compost. You want it to to be light & porous – so use a good potting or multi purpose compost that drains well. Some commercial composts can be quite compact, so I find adding some perlite (around 20% of your mix) helps soil stay light & airy. Microgreens don’t require deep soil to grow, so a shallow depth of between 1 to 2 inches works well. Firm the compost down lightly with you hand or the back of a spoon.

Microgreens will grow in almost anything, so if you don’t have any spare seed trays, you can re-use plastic food trays, egg boxes or even yogurt pots. The trays I’ve used below were old cherry tomato punnets.

Step 2

There are many types of microgreens & they’re largely grown in the same way. However, it’s worth reading the seed packet for any special instructions. Some larger seeds, such as mung beans, for example, benefit from soaking prior to use. This helps to soften the shell, aiding faster germination & even growth.

Step 3

Sow the seeds in your seed trays. You can either use your finger to make a shallow drill & sow a dense (but evenly spaced) row of seeds or scatter them evenly across the soil. I’ve tried both below to see which works best. Avoid big clumps of seeds, as this can lead to uneven growth. Lightly cover your seeds with a sprinkling of compost (microgreens need a period of darkness to germinate).

Step 4

Place your seeds on a windowsill that gets lots of light. Aim for a spot where your tray will get an even distribution of light. Water them gently with a mister or spray bottle, then continue to keep your microgreens lightly watered – you don’t want them to dry out. The compost should be moist but not wet. Microgreens are generally ready to harvest in between 7 to 21 days, depending on the type of seeds you’ve used. The leaves are ready when one true set of leaves have grown. Snip the shoots with scissors or pull out complete with the root and use.

Factors to Consider When Choosing Microgreens Trays

When choosing Microgreens Trays, focus on size, drainage, and reusability. These factors will boost your growth conditions and save space!

Conducting a thorough comparison of Microgreens Trays will help you identify the most suitable options for different microgreen varieties and the specific cultivation spaces you have in mind.

Size, Drainage, and Reusability
The size of your growing Microgreens Trays is crucial for determining how many microgreens you can cultivate. Proper drainage holes are essential to prevent overwatering and root rot, which can quickly derail your efforts.

When selecting Microgreens Trays, consider reusability it s a smart choice that supports sustainable practices and leads to long-term cost savings, especially for hydroponic setups.

Choosing the right dimensions is vital. Larger Microgreens Trays can accommodate more plants but may require additional space and resources. Smaller Microgreens Trays limit your yield but are typically easier to manage. In hydroponic systems, efficiency is key; adequate spacing and drainage are paramount.

A practical tip: experiment with various tray sizes and different types of microgreens. Additionally, considering how to choose the right soil for microgreen growth will provide you valuable insights on how to optimize both space and resource use effectively.

How To Clean Microgreens Trays?

Treating Microgreens Trays cleaning as a regular to-do on your urban farm is as vital as watering seeds or any other activity linked to growing edible flowers, microgreens or sprouts.

Step 1. Scrub
Start by giving those Microgreens Trays a good wipe-down to bid farewell to any lingering dirt. Grab a sponge, a paper towel, or a brush – your choice! Now, get into the nitty-gritty of it. Scrub the tray's surface thoroughly, leaving no trace of soil, seeds, or roots from the previous crop behind.

Step 2. Clean
Strive to eliminate as much dirt as possible. If you find the Microgreens Trays challenging to clean thoroughly, consider a good soak to loosen the stubborn dirt. At this stage, you can introduce the cleaning superheroes – soap or dishwashing liquid. These simple yet effective agents will help you banish the dirt, ensuring your tray gets the treatment it deserves for the upcoming planting session.
Step 3. Disinfect
Once you've cleared away the leftover seeds, soil clumps, and any lingering dirt, it's time to give your trays a germ-busting session. Let them take a dip in water mixed with disinfectant for roughly 20 minutes.🪣 This ensures not only a dirt-free zone but also kicks out any fungi or bacteria that might be lingering, posing a potential threat to your upcoming crop. It's like giving your Trays a shield against unwanted guests, securing a clean slate for your fresh greens.

Step 4. Dry
Once you've finished disinfecting the Microgreens Trays, the final touch is to ensure they are thoroughly dried. If feasible, let them air-dry outdoors.
The now cleaned and prepared Microgreens Trays are all set for the next cultivation cycle.

FAQ

Q: How do microgreen trays work?

A: Trays with holes are used for the majority of microgreens. They hold moisture well and keep growing media firmly in place. Since most microgreen seeds are quite small their corresponding roots are equally small and will not block the water from being absorbed up into the growing media during bottom watering.

Q: How do you clean microgreens trays?

A: We suggest using a mild detergent and hot water to remove any dirt or debris. After thoroughly rinsing your trays, spray them down with a diluted vinegar solution. Mix equal parts vinegar and water in a spray bottle and let the solution sit on the trays for about 10 minutes before thoroughly rinsing.

Q: Do I need holes in my microgreen tray?

A: The main recommendation is to make sure you are using material that is suitable for food production, that it's clean, and that the trays have drainage holes at the bottom. This will allow you to water the trays from the bottom without letting the water contact the greens, enabling the excess water to drain.

Q: What are Microgreens Trays?

A: Microgreens trays are shallow, flat containers designed to support the growth of microgreens. They are typically made from materials like plastic, and often include features like drainage holes and a tray cover.

Q: What Materials are Microgreens Trays Made Of?

A: They are often made from food-grade plastic for safety and ease of cleaning. Some higher-end models might use biodegradable materials or other eco-friendly options.

Q: What Size Are Microgreens Trays?

A: Sizes can vary, but common sizes include 10 x 20 inches (standard propagation tray size) and 12 x 18 inches. The size should be chosen based on the space available and the type of microgreens being grown.

Q: Can Microgreens Trays be Reused?

A: Yes, they can be reused multiple times. However, it’s important to clean and sterilize them properly between uses to prevent the spread of diseases.

Q: How Do You Clean Microgreens Trays?

A: Rinse with hot water, use a mild detergent if necessary, and sanitize with a solution of water and bleach (1 tablespoon bleach per gallon of water) or hydrogen peroxide.

Q: How deep should a microgreen tray be?

A: Because microgreens have shallow roots, this tray only needs to be one to two inches deep. If you look at the trays I use, you might think they're too shallow to grow much of anything, but I've found that microgreens can thrive with just a little bit of soil.

Q: Can you grow microgreens in pots?

A: Plants grown in containers can become compacted and waterlogged easily, so a soilless seed starting or potting mix is key! Tray: You'll need a tray (or container) to grow microgreens. People who grow them regularly often use shallow seed starting trays like these, but any container will work.

Q: Do I need holes in my microgreen tray?

Q: What is the best container for growing microgreens?

A: Now, I use either glass jars or food-safe, biodegradable plastic salad boxes to grow microgreens. While some home gardeners have developed elaborate urban growing systems such as hydroponics, you can repurpose plastic food containers. Microgreens will grow in any container you can find around the house.

Q: Do microgreens need a dome?

A: Cover the seeds with a thin layer of soil and gently water. Heat mats and humidity domes are not necessary but can help speed up germination and retain tray moisture, respectively, and should be considered in growing microgreens in cooler temperatures or in cooler environments.

Q: How often should I water my microgreens?

A: The amount and frequency of watering that your plants will need increases over the span of the grow. Newly germinated microgreens may only need 1 ½ cups of water once a day for the first few days. Once they are larger, a day or two before harvest, they may need to be watered twice a day.

Q: Do you have to buy microgreen seeds?

A: The seeds for microgreens are the same seeds you would buy to grow a mature plant. The only difference is that seeds labeled for growth as microgreens are often sold in larger quantities since you need to grow a lot of microgreens to get a full harvest.

Q: Is it cheaper to grow or buy microgreens?

A: These tiny delicate greens add color, texture, and flavor to a variety of foods as a garnish or an ingredient. Microgreens can be expensive to purchase, but can be grown at home for a more cost-effective option.

Q: What is the best water for microgreens?

A: Mastering the art of watering microgreens involves understanding and managing this process to ensure your plants thrive. Bottom watering guarantees even distribution and sturdy root growth while avoiding root rot. Use chlorine-free water with a pH of 6.0-6.5 to promote nutrient uptake.
