The 3 Best Microgreen Growing Trays You Need To Use For Great Results

In this day and age, gardeners and microgreens growers have access to so much equipment that it's hard to know what to turn to. Especially when it comes to microgreen growing trays.

The selection, both commercially produced and those at our disposal, is vast.

After growing microgreens for several years now, I follow a criterion when choosing equipment, including microgreen growing trays.

This article will outline these criteria, give you many options for microgreen growing trays, and provide my recommendations on the three best microgreen growing trays available.

The article also contains a video and podcast episode with my thoughts and recommendations.

Microgreen Growing Trays: The Planting Tray & Watering Tray

In our first Basics of Growing Microgreen articles, let's start with the growing tray.

We feel the microgreen growing tray is actually two trays or containers.

The planting tray is the container in which the microgreens will grow. The watering tray is the container used to water microgreens from the bottom.

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 it's dry.

The spacing of holes should be evenly spaced across the bottom with a reasonable size diameter that allows some of the soil media to contact 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 to the roots. So transparent or opaque trays aren't as good as dark or black trays. We aren't quite sure why; maybe the roots sense light and don't grow toward the trays' edges.

You should be able to use the trays over and over again year after year.

Watering Tray

A watering tray must be larger than the planting tray or allow the planting tray to slide into it. Obviously, the watering tray must be solid to hold water with sides high enough to not 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 in this aspect.

Again we rely on the soil media to wick-up water against gravity. Coconut coir does this well, as does pre-moistened peat moss. Dry peat moss is not as good.

You should be able to use the trays for years.

Using Water Trays

From our observations, the way to water your microgreens depends on the watering tray. 

Larger Watering Tray than Planting Tray

When you water microgreens in a tray (container) larger than the planting tray, regardless if there are one or more planting trays in the watering tray. You have to either guess how much water the soil will uptake or be around to dump out the excess.

Three soil media test

In most cases, you end up adding more water than needed. It's best to discard the extra water and let the trays drain the excess away.

Watering Tray Same Size & Shape As Planting Tray

In cases like this, such as with the Home Microgreens Planting and Watering Trays, water volume is much more forgiving.

It's almost impossible to add too much water as it will flow over the top when the planting tray is placed into the watering tray. 

We also found that as the water is displaced by the planting tray, it causes pressure to build up, forcing water up into the planting tray. This is ideal.

The Good and Bad Microgreen Growing Trays

As mentioned, there are so many microgreen growing tray options that it's impossible to list them all here. But we will go over several categories of growing trays and discuss the good, the bad, and the ugly.

The Not So Good Growing Trays

I love Pinterest; it's an excellent platform for both the user and the one placing new pins on the site.

However, some of the craziest ideas are posted on the boards. I'm not even going to link to them.

But they include growing microgreens in cracked eggshells, in the egg containers themselves, yogurt containers, or even in pots made from newspapers.

Now, they may look cute, ok, not so much for the newspaper pot, but they just aren't practicable. They use way more soil than the amount of microgreens you'd get from them.

These are great projects when the kids are driving you nuts, but not for the long haul.

That's what we are looking for here, growing for the long haul and not artsy.

Okay Trays, I Get It, But I Think We Can Find Better Microgreens Trays

These clamshells, mushroom containers, and the like repurposed from another use. 

I get it, re-use.

These can also be the gate-way drug into microgreens. 

These are very popular with those just beginning to grow microgreens. These microgreen growing trays are cheap (free), seemingly always available in the refrigerator, and people hate putting them in a landfill.

Many have low sides that keep the soil volume low. Some are large enough, greater than 25 square inches, and they're free! Well, I guess.

But if you look and feel them, they're not going to cut it. They're too flimsy, generally clear, and the holes are only along the sides and quite large. The deeper clamshells use too much soil; or you struggle to cut the micros if you keep the soil level low.

We Use These Microgreen Trays

We use Bootstrap Farmer Shallow Heavy-duty trays when we plant 1010 or 1020 trays. We also use their deeper trays to plant peas or other uses.

These trays will never be damaged with normal use.

When we grow microgreens for ourselves we use the Home Microgreens Trays & Soil. We like the amount of microgreens these trays grow and we find we can either stagger plantings or double up trays to fit our microgreen needs.

Remember, we are looking for a dark container with many evenly spaced holes. A container we can use for the long haul, like for years, not just two or three times before it becomes too worn to use.

Re-using them is excellent and keeping plastic out of the landfills is great, but they're going to end up there sooner than later.

Instead, go to a farmers market and buy produce in paper containers. Ask the grocery store produce manager to purchase produce packed in commercially compostable packaging (I'm using these now) and don't buy anything in plastic.

Also Included in This Category Are:

Plastic garden center trays are inexpensive and seem like the thing to use. I'll admit I started with them. I didn't want to invest in a thicker, sturdier, more expensive tray until two things happened multiple times.

First, they kept cutting me! Plastic cuts suck.

Second, they kept breaking or bending and dropping the microgreens when I tried to do more than one thing at a time. Eventually, I figured out a tray that costs $5 and lasted a lifetime was cheaper than a $1 tray that I was lucky to get out of it a year of constant use. 

I still have some though, I use them for light-weight domes or watering trays for 3 or 4 Home Microgreens Trays. 

Once they break, they're gone, though.

I put aluminum cooking trays in this category too. I don't see that they have any redeeming properties - leave a comment if you disagree. We love feedback.

Useful Trays That Fit A Need

These include ceramic and cotta terra containers, especially if you can find shallow rectangular or square ones.

Even though they miss one crucial aspect (generally only one to three large holes in the bottom), these will grow microgreens well. They're long-lasting (unless you drop them), dark, hold moisture well, and you can get them anywhere in an uniform size.

However, they must fit a need; by that, I mean they fit on a narrow windowsill or shelf. Your counter space is limited, and they fit neatly up against the counter splash out of the way. You can also buy wall mounted hangers that support these type of containers.

Recommend Microgreen Growing Trays

Below are my choices of microgreen trays. I use these trays over and over again. In fact, I've never had one break on me or dump any microgreens except when I flat out drop a tray off a top happens.

Let's progress from smaller sizes to the larger.

Bootstrap Farmer 5 by 5 Microgreen Growing Trays

We only use these for specialty microgreens, although I could see why people would want to use them for growing everyday microgreens.

By specialty microgreens, we're talking about popcorn, a microgreen with a small serving size but a robust flavor, and needs a talk blackout dome for it to grow tall without light.

microgreen trays

So we don't use 5 by 5 trays very often, but they're handy when we need them. 

People also like to grow many varieties of microgreens in smaller quantities. As eight of these 5 by 5 microgreen trays fit into a regular watering tray, they are popular.

The Home Microgreens Store usually has these in stock, as well as does Bootstrap Farmer

Home Microgreens Growing Trays

These are our most popular sellers. The trays are around 38 square-inches and can grow 2 or more ounces of microgreens. The dimensions are approximately 7.5-inches by 5-inches.

We love these trays' low profile; the angled sizes cut down on the soil volume yet still produce a sizable growing area.

microgreen trays

These are the trays including in our microgreen kits. We also have several different buying options available.

Up to four Home Microgreens Planting Trays can fit into a 1020 watering tray!

The trays are made from food-safe materials and are very durable. There are several ledges inside the tray that are used as guides for soil levels.

The Home Microgreens Watering Tray fits tightly around the Home Microgreens Planting Tray.

Bootstrap Farmer 1010 Microgreen Growing Trays

We use these trays all the time! We love them when we don't want to grow a large 1020 tray of microgreens.

1010 microgreen trays

All of Bootstrap Farmers trays are:

  • Made from BPA free food safe polypropylene plastic (#5)
  • Guaranteed durability backed by a 2-year warranty
  • Dimensions are 10.5 by 10.5 by 1.25 and 2 fit into a standard 1020 tray or microgreen tray
  • Available with drainage holes or not.
  • Free shipping over $49.

We have never had one of these trays break.

And are they strong! Make sure you take a look at the video above as I put a 10-pound weight in a 1020 tray and could lift it one-handed and not have the tray bend. The 1010 trays are made of the same material.

If you're looking for one or two, the Home Microgreen Store carries these trays. It may be less expensive to buy more from Bootstrap Farmer, though.

Bootstrap Farmer 1020 Microgreen Growing Trays

If you use a lot of microgreens, maybe the 1020 trays are for you. 

1020 comes from the size; the microgreen growing trays are about 10-inches wide and 20-inches long. The tray shown below is 1 1/4-inches tall. Perfect for microgreens.

microgreen trays

As you can see, the trays come both with holes and without. The trays are made of the same material and have the same warranty (if purchased at Bootstrap Farmer) as the 1010 trays.

I like these trays, which goes for the 1010 trays too, is that the bottom raised portion of the tray is beveled and not very high. It's high enough to let water drain if you're using the no holes tray as a watering tray.

But if you use the microgreen growing tray with holes as a planting tray, the soil media comes out of the tray much easier and cleaner than other types of 1020 trays. 

We use these trays to grow the microgreens we sell to retail customers every week. 

Take care of these trays, and they will last a lifetime.

These are great trays and very useful to have. You can purchase them right from Bootstrap Farmer with free shipping if your order is over $49 when this article is published. Click here to see the trays on Bootstrap Farmers website.

There is also a full depth heavy-duty tray that I use quite often from Bootstrap Farmer. The ridges are more pronounced, but this only makes the tray stronger.

What Makes A Great Microgreens Growing Tray - Review

Here's what we look for in a growing tray - both planting and watering.

Durability - The trays need to hold up to everyday use year after year. If the tray won't break or crack if it's dropped or banged against something hard.

Strength - regardless of the size, you need to be able to lift the tray from one end while it's full of moist soil. At some point, you'll come across a situation where you need to take one hand off the tray, whether you trip, stub your toe, need to grab something else that is falling. When that happens, the tray already in your hand needs to support its own weight without breaking or bending.

Low Height to Soil Volume Ratio - Deep trays waste soil compared to shallow trays. Microgreens can grow in very little soil. Deep trays are not necessary and only increase the amount of soil needed to fill the tray. A half-filled tray is harder to weigh down during blackout, reduces light to young microgreens, and makes it much harder to harvest. Soil levels near the top of the tray eliminate all of those problems. Shallow is better than deep.

Evenly Spaced & Reasonably Sized Holes - Planting trays should have holes large enough to allow soil to water contact during bottom watering without much soil falling through. The holes should be numerous and evenly spaced around the bottom of the tray perimeter and across the bottom surface.

Bottom Ridges or Tight Fit - Watering trays should either have ridges on the bottom to elevate the planting tray so extra water can drain. Or, the watering tray should be the same size and shape as the planting tray. A tight fit doesn't allow for one time overwatering, forcing the water higher into the soil profile. Note: You may not be able to overwater with a tight-fitting watering tray with one watering event. But you can if you water every day. Be sure the planting tray needs water before watering.

Health & Safety - You can throw durability and strength under H&S too. Still, more to the point, microgreen growing trays shouldn't have sharp edges to reduce the possibility of cuts to the fingers and hands. Also, they should be made or composed of food-safe materials.

Needs to Fit the Space You Have Available - Whatever microgreen growing tray you use needs to fit into space you have available. Other people's recommendations aren't any good to you if those trays are too big or cause a waste of space.

The Microgreen Growing Trays We Use Everyday

There are so many different kinds of microgreen growing trays it is impossible to list them all. 

If you have a preferred microgreen growing tray, leave a comment below.

We always like to see what everyone is using and learning your thoughts on the equipment you use. 

If you're not set on any particular tray, give one or more of the trays listed below a try. We know you'll like them, they work great for us, and there is no reason they won't work for you.

The Home Microgreens Tray

These trays are made from food-safe, number 5 plastic, and have a raised outside perimeter rim that allows the middle of the tray to drain.

The planting tray has 26 evenly spaced drainage holes.

The tray sides slope toward each other from top to bottom, reducing soil volume needed by over 40%.

The watering tray fits snuggly under the planting tray forcing water up into the soil.

The tray is strong because of the raised outside perimeter rim, and the rolled over top has angled supports.
