Just a few years ago it was much harder to find great microgreen seeds online.
Recently, as more and more people realize the benefits of microgreens, long-running seed suppliers are stocking more microgreen seeds and products than ever.
At the same time, entirely new businesses are popping up that specialize in microgreens.
However, there are only a few sources of microgreen seeds that I trust.
These are brands that have outstanding quality control, customer service, prices, and selection.

From the beginning, Kitazawa Seed was the premier source of rare and specialty Asian seeds in the country. At first, most of Gijiu’s customers were Japanese-Americans who purchased his seeds to get access to important ingredients used in traditional recipes.

Where to Buy Microgreen Seeds In Canada
Microgreens aren’t just popular here in the U.S – they’ve seen massive growth in Canada, too. So for all you Canadian growers out there, here are a few seed suppliers in Canada.
Microgreen Seeds vs Regular Seeds
There is some debate around the difference between microgreen seeds and regular seeds. Are they the same thing? Do you need to buy seeds that specifically say “microgreens” on the label? What really matters when buying seeds anyways?
I’m going to go into detail and answer all of these questions and more.
Can normal seeds be used for microgreens?
Normal seeds, the ones you would use for gardening, hydroponics, or any other type of growing, can be used for microgreens. There isn’t a special type of seed out there grown just for microgreens, seeds are seeds.
Lemon Basil Seeds and Lemon Basil seeds For Microgreens are the same seeds!
However, the important difference between the two is how the seeds have been bred, tested, and treated. More on this in the next section…
Why are microgreen seeds more expensive than regular seeds?
Microgreen seeds are tested and selected to be of higher quality in terms of germination rate. This means that companies select seeds with the highest chance of sprouting.
Bulk bags of regular seeds contain many nonviable seeds. In a small tray of microgreens, even if just 20% of seeds fail to germinate, their absence will be seen and felt.
Furthermore, most seeds come with a coating of chemicals, usually antimicrobial or fungicidal. These coatings can be useful for seeds that will grow for many months or years, but undesirable for microgreens that will be consumed in a matter of weeks. This is because the chemicals don’t have time to wash off and break down. With microgreens, chemical coatings will end up on your plate and in your body!
By buying seeds labeled “microgreen,” you avoid these potentially harmful chemicals.
Also, microgreen seeds are never genetically modified, or GMO.
Lastly, not all plants or varieties of plants do well in microgreen systems. By buying seeds specially selected for microgreens, you can be sure they make sense to grow that way.
Most Important Terms For Microgreen Seeds
Even within the classification of “microgreen seeds,” there are differentiating factors. Here are the terms you need to know when shopping for microgreen seeds.
What are non-GMO seeds?
GMO, or genetically modified organism, refers to a plant or seed that has been manipulated through modern biotechnical methods. Instead of being bred in a field or garden, GMO seeds are bred in a laboratory.
Because of the controversy surrounding GMO plants and seeds, as well as their possible risks to human health and the environment, almost all microgreen seeds are non-GMO.
What are organic seeds?
Organic seeds come from plants grown organically and sustainably, without the use of synthetic chemicals or GMOs. To be considered an organic seed, the farm that grows it must be certified organic by the USDA or another reputable organization.
What are heirloom seeds?
An heirloom seed has a special heritage. It has been passed down for generations usually within a family or farming community. These seeds haven’t been hybridized and retain their original traits from generation to generation. Also, heirloom seeds must be open-pollinated.
Heirloom seeds are painstakingly collected, preserved, and sold because they contain unique genes that create great flavors and other desirable characteristics.
What are open-pollinated seeds?
Open-pollinated seeds come from plants that are pollinated by insects, birds, wind, or other natural mechanisms. Natural pollination leads to greater genetic diversity in plants, which leads to greater variation, which, over time, increases the speed at which plants adapt to local conditions and weather patterns.
Not only is open-pollination beneficial to local ecosystems, but it can result in plants with unique and favorable adaptations.
All heirloom plants are open-pollinated, but not all open-pollinated plants are heirlooms.
List of Popular Microgreens to Grow
There are hundreds of varieties out there that work well as microgreens. Some are incredibly easy to grow, and others take a bit of practice to get right.
Luckily, all types of microgreens are considered incredibly easy to grow—anyone can get started with microgreens without much experience or technical knowledge.
One of the first steps in your microgreen journey is figuring out what you want to grow.
Here are some of the most popular and interesting microgreens out there, grouped by level of difficulty.
- Edible marigold
Don’t be discouraged if your dream microgreen is in the intermediate category. The difference between an easy and intermediate microgreen is usually just getting the watering right.
At the end of the day, all microgreens are fairly easy to grow. Start small and give it a try!
How are microgreen seeds made?
Microgreen seeds, just like regular seeds, are made mostly on seed farms.
Growers of all sizes, from gardeners and small family farmers all the way up to large corporations, grow plants specifically for seed production.
An entire field or a portion of it will be set aside for seed. The plants grow just like any other, but when they are harvested and processed, the seeds are saved and readied for selling.
From there, seed growers either package and sell their seeds directly to consumers or sell them wholesale to larger seed companies.
Microgreen seeds, being non-GMO and often heirloom, are more likely to come from small, local farmers with sustainable practices than some other types of seeds.
And by buying from a great retailer like Johnny’s, TrueLeaf, or one of the others listed above, you can be sure that you’re getting only the highest quality microgreen seeds and supporting agricultural businesses in the process.
How many seeds are in a Microgreen tray?
The number of seeds that go in a tray depends on the species and variety of the plant you want to grow. The most accurate way to measure microgreen seeds is by weight. While most types of seeds fall in the region of 20-30 grams per tray (10×20 tray), it all comes down to the size and weight of the seeds themselves.
For example, if you are seeding a tray with basil seeds you should spread 7 grams of seed evenly atop the growing media. But, for corn, you will need 200 grams of seed for the same tray size.
This is simply because individual basil seeds weigh much less than individual kernels of corn. A similar number of seeds will go into each tray, but the two types of seeds have different weights.
Also, some varieties need to be sowed at slightly higher or lower densities.
The best way to know exactly how many seeds to put into your tray is to use a seed density calculator.
Calculators can tell you the optimal seeding density and the recommended number of seeds to put in whatever size tray you have.
