Growing microgreens can be an awesome hobby or a great way to start a business doing something you love. You can choose from a variety of types, like the vibrant and beautiful amaranth microgreens, or delicious broccoli microgreens.
It’s a quick and easy hobby for any gardener to get started with, but you will need a few pieces of equipment to get growing. Aside from microgreen seeds, one of the main things microgreen growers need is microgreen trays. There are plenty of options on the market, but let’s look at which ones are right for you.
The Best Microgreens Trays You Can Buy
I tried 7 different trays from varying companies, including Greenhouse Megastore, Bootstrap Farmer, and of course a few of the cheapest gems from Amazon.
Here are the best trays I found after running a few tests, including walking over them all because sometimes you accidentally step on a tray. So which ones hold up the best?
I love Bootstrap Farmer for buying microgreens trays because they make it super easy to understand what you’re buying. You can select with holes, or without holes, and they’re upfront about the depth and length of all their products.
For microgreens you typically want a bottom tray without holes and a top tray with holes for drainage. The important thing to keep in mind when you’re buying trays is that they fit together, so I’d recommend sticking with the same brand.
They also sell shallow microgreens trays making it easier for you to harvest your greens. As I mentioned above, 2-3 inch deep trays are not uncommon, and they also sell those sizes for seed starting, so make sure you’re getting the shallow microgreens trays when your place your order.
Bootstrap Farmer trays are some of the most heavy-duty trays I’ve used, so the extra cost is worth it to me. They’ll also replace your trays for free if they break or crack within the first year or two.
2. Paperpot Trays
These are considered some of the best on the market for commercial growers. But they are much more expensive and come in 11×22 inch flats instead of the standard 10×20.
3. Handy Pantry
These trays are BPA-Free and would be what I was referring to when I said they were “middle of the road” in terms of price.
They get good reviews and are sturdy, but they’re not going to be the same quality as the two companies above.
4. True Leaf Market
True Leaf Market has some great options for buying trays. They’re not as sturdy as the Bootstrap Farmer ones, but they’re also not as expensive.
The trays I bought from them were some of the more flimsy trays I bought, but if you don’t mind buying new ones every 1-2 years, they’re great for the price.
5. Craigslist or Facebook Marketplace
You can usually find gardeners or microgreens growers who ended up ordering too many trays or sadly have gone out of business and are selling their extra trays online.
No matter where you get your microgreen trays, always make sure you sanitize them before using them. If you had issues with fungus or bacteria in the past, or even if you didn’t or aren’t sure, it’s always a good idea to make sure your medium or containers are clean so you’re not spreading that environment around to future plants.
Microgreen Trays Buyer’s Guide
Now that you know some of the better companies to get trays from, let’s walk through some of the more important things to consider when buying a microgreen tray.
Microgreen Trays & Sizes
There are quite a few different sizes for germination trays that you are likely to find.
10×20 Microgreen Trays
Also called “The OG” size (kidding). The standard size for microgreen growing trays is 10 x 20 inches, and are also called “1020 trays.” But keep in mind that not all 10×20 trays are created equal. That’s kind of frustrating right? Well, it is when you aren’t aware of it.
These sized trays fit well next to each other on a cart, which is why they are quite popular with microgreens growers.
A more square shape is good for smaller spaces or breaking up different types of seeds you’ll be growing. The same applies here as does the 10×20 trays – just because it says it’s a 10×10 inch tray, check the fine print and details as the sizes might be slightly off.
These will also fit well on a cart or shelving unit, as they are just half the length of the standard 1020 trays.
Plastic trays vary by depth, and while most will work together, this is a big consideration and not something to gloss over.
A shallow tray tends to work better if you want to grow microgreens, but if you’re starting seeds for a full garden, you’ll likely want to use deeper trays.
A lot of “standard” 10×20 trays are 2-3 inches deep, which can make it hard to harvest microgreens.
How Deep Should Soil Be For Microgreens?
Microgreens usually need at least 1 inch of soil to grow properly, but you can increase that up to 4 inches. While you can grow them in less, you might not get as good a yield at the end of the growing period.
This can generally increase yields when you go to harvest as well because you can get a little more of the root system in your product.
If you’re starting seeds indoors for eventual transplantation into your garden, you’ll probably want to use deeper trays that can hold more soil and roots at the plant base and give the roots more space to spread out.
Drainage Holes or No Drainage Holes?
You’ve probably seen these two types already if you’ve done any searching for trays. Some have holes in the bottom and some don’t. It’s that simple, but it’s also something you can forget about quite easily if you’re not paying attention.
You want to have one tray with drainage holes where you actually put your soil or seed starting mix, and place that inside of another tray that doesn’t have drain holes.
Depending on your microgreen setup, you’re probably going to need a combination of growing trays that have bottom holes and ones that don’t.
Planting Trays – a tray with holes in it for proper drainage
Watering Trays – the tray you put the planting tray into water your seeds from the bottom.
A lot of people will put their seeds and soil in a tray with drainage holes so they can make sure the soil isn’t staying too damp, and then place that inside of a tray without holes to keep water from leaking all over the place.
This is also a good setup for bottom watering your microgreens. Many microgreen growers will probably tell you its best to water from the bottom to avoid mold and fungus issues with overwet microgreens. I would agree here as you’re also removing good airflow from the plant base when you’re letting them sit in unused water.
How Many Trays Do You Need?
This is where planning comes in. It’s best to know how many of these trays you’re going to need before you go ahead and purchase them. Of course, you can always buy more, but there are a lot of places that offer bulk discounts for purchased 10 or more trays.
Quality and Durability
This is a big one to consider when buying your trays.
Are you going to be growing microgreens for years to come, or is this a one-time experiment you recently got excited about?
If you’re going to be doing this for a while or are growing microgreens as a business, then you’re going to want to spend a little more to get better, more durable trays. The cheap ones might cost half the price, but only last one season, while the “more expensive” ones will last 5+ years.
It’s a no-brainer which one to go with as long as you plan to be growing microgreens for at least 2-3 years. Also, it’s just good for the environment to not be looking at everything as a one-time use item and instead use it again and again.
If this is a test, go ahead and jump on Amazon and just grab these cheaper trays that are in the middle of the road when it comes to price and get good reviews.
This is something I won’t budge on when it comes to growing any kinds of plants. The plastic needs to be BPA Free. This is why I won’t use red plastic cups if I didn’t see the packaging first. BPA is not something to mess around with and I’m not really interested in those chemicals leaching into my plant starts or microgreens.
If you’re going to be selling these, you’re going to want to get trays made from food-grade plastic, which will naturally be BPA-Free.
Colored or Black
Some companies like Bootstrap Farmer, sell colorful microgreen trays which is great to help you keep track of which trays have which seed, which ones were started when, or which trays are using which soil if you’re running tests. The possibilities are endless! 🙂
- Extremely Durable
- Highest Quality Trays on the Market
- Can Re-Use Year After Year
- Can Be Expensive
Frequently Asked Questions
Do Microgreen Trays Need Holes?
While you can grow microgreens in plant trays without holes, it’s going to make the job a little more challenging. You’ll have to be very careful not to overwater your microgreens because without the drain holes, your plant’s roots will be sitting in water which can lead to root rot.
What is the Best Soil for Microgreens?
What Lights to Use for Microgreens?
You can use a wide variety of lights to grow microgreens, including a fluorescent shop light you might have lying around. While many growers use LED grow lights for their efficiency, they can come at a higher cost. I like using these long lights as they fit well on my grow shelves.
It can take a lot of patience and care when you first start growing microgreens. After you grow your first few trays, it gets much easier.
