If any of you made New Year resolutions to eat healthier in 2016, then this blog post will definitely be a great resource. Microgreens are full of nutrients and great as a salad, in addition to being a fun, indoor gardening project. It's the perfect activity to try during this cold, winter season. Cassie Johnston of Back to Her Roots, a healthy eating and gardening blog, is showing us just how it's done. By then end of this post, you'll be able to grow your own microgreens at home, too.
You might be asking, well what the heck is a microgreen? Well, a microgreen is the new, tender shoot of a vegetable plant. It’s what happens if you let a sprouted seed go a little bit farther into growing, but don’t let it completely mature. These greens are tender, sweet, and insanely good for you—they are literally one of the healthiest veggies on the planet! Newly sprouted, tiny microgreens have up to 4o times the nutrient impact as their mature plant counterparts. 40 TIMES! Just a single example: microgreens from red cabbage seeds have 40 times more vitamin E and six times more vitamin C than fully-grown red cabbage. Crazy, right?
Microgreens make an awesome winter substitute for lettuce or other cooking greens—we like microgreen and sprout salads in the winter when our garden isn’t producing. You can also use them on sandwiches, in stir-frys, or in casseroles. And the best part, they are insanely easy to grow indoors. Like, I promise you can do it. Even if you’ve killed stuff before. You can do it!
So, what do you need to get grow your own microgreens? Not much, actually:
-
Microgreen Seeds: You can use almost any vegetable seed to grow microgreens (some are tastier than others, though), but a lot of companies offer special microgreen seed mixes that are a great option for first-timers. They have a nice variety of tastes, textures and nutrition. I really like the microgreen mixes from Johnny’s Seeds. If you don’t want to go with a mix, cilantro, kale, radishes, basil, and beets are all great seeds to start with.
- Soil: Seed starting medium is your best bet, but honestly, you can grab just about any potting mix or garden soil from the store and have good luck. I’d personally steer clear of soils that have fertilizers mixed in—you don’t want those yucky chemicals in your greens! We make our own seed starting mix, but there are some really nice organic options available at most stores this time of year. I even saw an organic potting mix at my grocery store last week!
- Tray: You’ll need something to grow your microgreens in. We use regular seed starting trays—available at most garden centers and hardware stores—but honestly, you can use pretty much anything. These greens aren’t going to stay in them very long, so it doesn’t have to be anything special. A plastic tote or a galvanized tub or heck, even a baking dish!
- Light Source: There are two ways of going about this—the natural way or the artificial way. For the natural way, all you need is a sunny window. Easy! Unless you have a cat, like we do, and then they will make that warm tray of soil their bed. So we do our microgreens under a fluorescent light in a cat-proof room. You don’t need any kind of special light or lightbulbs. Just get the cheapest fluorescent shop light you can find (we have this one) and outfit it with two regular fluorescent lightbulbs. They’ll try to tell you you need special full-spectrum light bulbs for your grow lights—at about four times the price—and they might make your greens grow a touch better, but not enough to warrant the price in my opinion. Hang the light about four inches above the table where you’ll set your tray.
- Water: Duh. I recommend using a spray bottle for microgreens.
First
step is to fill up your tray with soil. Since these plants aren’t
going to be in there very long (9-12 days), they won’t develop a
very intricate root system, which means you don’t need a whole lot
of soil. About two inches worth should be more than enough.
Then
you spread your seeds across the surface of the soil. No need to
worry about getting it perfectly even or spaced out equally.
You
want to put a pretty thick coating down. Unlike when you’re growing
a full, adult plant, you don’t have to worry about overcrowding
with microgreens. Pack ’em in.
Next,
take a little more soil in your hand, and sprinkle it over the seeds.
You’re just looking for light coverage here. Again, no need to be
perfect. You don’t have to cover every seed exactly the same.
Then
take your hand and lightly press down all across the tray to really
set the seeds into their new home.
Last
planting step: give ’em a good drink of water. The spray bottle is
for later, now is the time to use a watering can or the mist option
on your hose sprayer. You don’t want them swimming in water, but
you do want them very, very damp.
Then, put your tray in your sunny spot and wait! Or, if you are putting them under a grown light, place them directly under the light. You actually want the light to almont be touching the top of the tray (the light in this picture is actually a bit too high up.)
A few days later, you’ll see even more seed germinating, and then the true leaves starting to show. These are the ones that actually start looking like the plants you are used to, albeit really tiny, adorable versions.
And
then after a little over a week, you’ll have a whole tray full of
beautiful microgreens. You can choose to harvest at any point after
the true leaves show up.
I
normally let mine go until about the 10 day mark, when the greens are
about two inches tall.
To
harvest, you can either clip the greens with sharp kitchen scissors...
Or
do what I do, and pull out the greens and shake off the extra soil.
You’ll need the soil to be extra dry to do it properly, so I stop
watering
a few days before I’m going to harvest. Then, on harvest day, pull
up the greens, and shake of the excess soil.
Then
I do 3-4 wash cycles on the greens, making sure they are full
submerged in cold water each time. Then spread them out on a towel
and dry them off slightly (a salad spinner works, too). To store, I
then wrap them in paper towels and place in an airtight container in
the fridge.
The
soil can then be composted, and you can start all over again! Or, if
you’re really on top of things, you can have multiple trays going
at the same time. I’ve found that starting a tray each week ends up
working out well for us—it takes us about a week to get through the
harvest from one tray.
See,
super easy, right? You can totally grow your own food! I promise.
Happy growing!
