Growing microgreens without soil
 

Microgreens, a recent gardening trend, offer the remarkable advantage of swiftly cultivating edible plants within a mere 10 days, as they are harvested in their seedling stage.

Indeed, cultivating microgreens proves to be a straightforward endeavor, and the intriguing aspect is that it’s entirely possible to engage in this process sans soil.

Yes, you read that correctly; the cultivation of microgreens can be accomplished without the conventional use of soil through the method of hydroponic gardening.

Hydroponics, in this context, presents an innovative approach, enabling the growth of plants, including microgreens, without reliance on soil. Instead, alternative growing mediums, often referred to as substrates, play a pivotal role in providing the necessary support for the roots within the hydroponic system.

These mediums encompass a diverse array of materials such as coco coir, Rockwool, perlite, and surprisingly, even the common household item – paper towels! This technique not only adds an element of versatility to microgreen cultivation but also underscores the adaptability of hydroponic systems in diversifying the choices available to enthusiastic gardeners.

In my perspective, the emergence of hydroponic gardening as a viable means of cultivating microgreens without soil is a testament to the continuous innovation within the gardening community. This not only facilitates a quicker growth cycle but also presents an eco-friendly alternative by minimizing the use of traditional soil. The incorporation of unconventional mediums like paper towels showcases the creativity inherent in gardening practices, challenging preconceived notions and expanding the possibilities for aspiring horticulturists.

How To Grow Microgreens Without Soil

 

1. Prepare Your Water

 

Since hydroponics uses water, the quality of the water that you use matters. Springwater or rainwater is best.

 

You can also use tap water but it’s recommended to let it sit for 24 hours after boiling it to remove the chlorine. Then test your water using the pH kit and adjust to a ph level of 6.

 

2. Fill the Trays

 

The next thing you have to do is prepare the growing medium in the trays. Spread the coco coir evenly throughout the tray.

 

It should be one inch deep evenly across the entire tray.

 

If you choose to use the hemp grow mats then just use one per microgreen tray, and if you choose to use paper towels then fold them about 6-8 times.

 

3. Plant the Seeds

 

The packet of seeds you bought should have instructions on the package.

 

Typically, you take about two to three tablespoons of seeds and spread them evenly across the growing medium.

 

Make sure there aren’t any lumps of seeds stacked on top of one another and fill in the gaps. The seeds don’t need too much space.

 

It only takes 7-14 days to harvest, so they don’t need that much room to grow. You won’t need to space them far apart compared to full-grown plants or seedlings.

 

4. Water And Cover Your Seeds

 

After spreading the seeds across the growing medium, keep them moist with a spray bottle.

 

Keep the tray covered, which keeps the medium moist, or keep them in the dark area.

 

Having proper air circulation will also prevent any mold from growing, so it’s always helpful to have a small fan around.

 

5. Germinate the Seeds

 

It takes 3-4 days for the seeds to germinate if you keep them warm around 70℉.

 

During those days, keep the tray dark and warm while ensuring there is air circulation because mold grows without airflow.

 

Make sure you keep the soil tray moist, spraying it every 12 hours or so. It’s essential to use the pH water created in step one.

 

Within a few days, germination begins, and the seeds sprout, which is when you move to the next step.

 

6. Uncover And Give Light

 

Your microgreens should be ready to uncover after 3 or 4 days (7 days for beet & cilantro).

 

You can judge this by watching for when the baby leaves (cotyledons) of your microgreens first emerge and then waiting one more day.

 

It is important to keep your microgreens in the dark for the first 3 to 4 days to force your microgreens to grow in the struggle for light.

 

This will help you grow strong microgreens. Once you uncover the tray, make sure your microgreens get plenty of light.

7. Check Daily

 

Your microgreens should have the right balance of water from now till harvest.

 

If necessary, replenish water by sprinkling or pouring water over the growing medium, avoiding the leaves as much as possible.

 

You can also water below the growing tray so the roots of the microgreens can have enough water until harvest.

 

Do not use the spray bottle anymore, as the spray bottle will increase the chances of mold growth.

 

Step 8. Time To Harvest

 

Most microgreens will be ready to harvest in just 10 days. Some microgreens can be harvested as early as 7 days.

 

Most microgreens will not last past 14 or 15 days before they must be harvested. Move your trays to a cool, shady place.

 

If your microgreens are harvested when it is too hot, they will wilt very quickly after harvesting.

 

If harvested when cool (late evening, early morning), they will tend to stay fresh and crisp.

 

Use scissors or a knife to cut the microgreens directly from the growing medium.

 

Think of it as giving your microgreens a haircut. Just cut about 2/3rds of an inch above the growing medium, avoiding the roots.

 

Microgreens taste best if eaten right after harvesting, although you can store them in the refrigerator for several days after.

5 Benefits Of Growing Microgreens Without Soil

 

Most people decide to use soil for there’s grows, and while that is okay.

 

Here are some benefits you may want to consider for growing without soil:

 

1. Reduces The Cost of Growing

 

Instead of having to spend that extra money on soil, you can instead just use paper towels which are far more affordable and take up less space.

 

You also use less water since most of it is just recycled back into the system.

 

2. Gives You More Control of Watering

 

Over/under-watering your soil is much more likely to happen than if you were to just use the same water from the beginning of the grow.

 

Since you will be using the same water throughout the entire grow you will not have to worry about over/underwatering.

 

3. Year-Round Growth

 

Growing microgreens hydroponically is typically done indoors all year round because the only necessary components for the survival of microgreens are water and light.

 

You also have more control over the indoor temperature so you can provide the most ideal growing environment.

 

4. Uses Less Water

 

When using a hydroponic method, you re-use the water in the growing tray. Pretty much the water is used in a cycle.

 

Which typically only requires you to water microgreens just a few times throughout the entire grow.

 

5. Creates Less Mess

 

Growing microgreens without soil is generally going to create less of a mess, as you don’t need to worry about spilling soil throughout your house when cleaning the grow trays.

 

Especially if you are growing on your kitchen counter or bedroom window!

So here is what you are going to need:

 

1. Seeds

 

The first thing that you need to do is buy seeds.

 

There are many different places you can buy seeds but I highly recommend you buy from trusted sources like True Leaf Market and Sprout House Seeds as they have high-quality seeds.

 

2. Growing Medium

 

Even if you aren’t using soil, you need some sort of medium to hold the seeds in place as they sprout.

 

These growing mediums are going to support the roots of the microgreens so they grow straight and tall.

 

There are many different kinds of growing mediums to consider. Here are a few to consider:

 

Coconut Coir: Typically, coco coir is dried and packaged very tightly which requires you to add water to it.

 

This will cause it to expand and become fluffy, making it seem much more than what it was initially. This is overall a great growing medium to use and it’s not expensive.

 

Hemp Growing Mats: Hemp mats are easy to use and are generally less messy but are quite expensive compared to coco coir and other growing mediums.

 

Paper Towels: Paper towels are great to use as you most likely already have some in your home.

 

But be careful with what kind you use because if they contain inks or dyes that could contaminate your grow.

 

So make sure to use Non-toxic paper towels that are free of dyes, inks, and fragrances. Here are some really good ones

 

3. Grow Trays

 

You are going to need a tray or two for growing microgreens. You also can buy a microgreen kit that will include a high-quality grow tray.

 

The tray should be around 1.5 to 2 inches deep and about 20 inches long if you want to grow lots of microgreens at once.

 

Make sure the grow tray you choose does not have any holes in them and is specifically meant for hydroponic growing.

 

4. Grow Lights

 

At first, the seeds need to germinate, and at that point, you don’t need lights. After 3-4 days, you will need grow lights to start the photosynthesis process.

 

Consider buying LED grow lights or just use direct sunlight if you have a well-placed window.

 

5. pH Testing Kit

 

Microgreen seeds are sensitive to the PH of water. Microgreens thrive at a PH of 6. Most tap water is at a neutral PH of 7, so I highly recommend you buy a PH Kit to adjust the PH.

 

Make sure to only water your microgreens with water you have balanced to an acceptable PH. It’s also helpful to use filtered water to remove any chlorine from the water.

 

6. Spray Bottle

 

You’ll need a spray bottle filled with water to lightly mist your microgreens as needed.

 

Make sure the bottle is cleaned thoroughly and if needed, purchase a new one from the store. These are cheap!
