Benefits of Growing Microgreens Indoors

 

Cultivating microgreens within the confines of your indoor space empowers you with a heightened ability to regulate both humidity and temperature, thereby creating an optimal environment for their flourishing.

This controlled setting becomes a crucial factor in ensuring the ideal conditions necessary for the robust growth of your microgreens. When humidity levels soar excessively, the risk of mold development increases, posing a potential threat to the entire cultivation process.

Fortunately, the advantage of indoor cultivation lies in the diminished likelihood of losing control over humidity and temperature. Unlike the unpredictable outdoor conditions, the indoor environment allows for a more stable and manageable climate, safeguarding your microgreens from potential harm.

Yet another noteworthy advantage associated with indoor growth is the effective prevention of unwelcome pests that could compromise the integrity of your microgreen harvest.

Pests such as gnats and spiders, if left unchecked, can render your microgreens inedible, necessitating their disposal— an undesirable outcome for any grower. By opting for indoor cultivation, the risk of such pests infiltrating and sabotaging your microgreens diminishes significantly.

In essence, the decision to grow microgreens indoors not only grants you greater control over environmental factors but also acts as a deterrent against potential pest-related setbacks. This approach not only reflects a strategic and practical consideration for the cultivation process but also aligns with a broader philosophy of sustainable and mindful living. The intentional control of your growing conditions exemplifies a conscious effort to produce not just microgreens but a harmonious and thriving microcosm within the confines of your indoor gardening space.

 

Why You Should Grow Microgreens Indoors

 

Establishing a specific area within your home exclusively for cultivating microgreens emerges as the optimal approach for indoor microgreen cultivation.

In addition to the advantages previously outlined, the practice of growing microgreens indoors significantly streamlines the entire cultivation and harvesting procedure, introducing a level of convenience and efficiency.

The dedicated indoor space shields your microgreens from potential threats such as pests, undesirable humidity levels, temperature fluctuations, and insufficient sunlight exposure, thereby alleviating concerns that could jeopardize your harvest.

The beauty of indoor cultivation lies in the comprehensive control it affords you. You wield authority over crucial factors like light exposure, environmental conditions, and the overall safety of your microgreens. This control extends beyond mere convenience, shaping a holistic and tailored environment conducive to the thriving growth of your microgreens.

From a personal standpoint, this intentional control over the cultivation space not only optimizes the practical aspects of growing microgreens but also instills a sense of responsibility and connection to the nurturing process. By curating a dedicated space within your home for microgreen cultivation, you not only enhance the efficiency of your harvest but also foster a deeper relationship with the plants, aligning with a mindful and sustainable approach to indoor gardening.

In essence, designating a specific indoor space for microgreen cultivation embodies a strategic and thoughtful endeavor, marrying practicality with a nuanced understanding of the needs of these miniature crops. This deliberate approach not only enhances the overall success of your indoor microgreen garden but also underscores a commitment to a harmonious coexistence with nature within the confines of your home.

Materials You Need To Grow Microgreens

 

Shelving

 

Shelving is important for growing microgreens as it allows you to grow lots of microgreens in a small area.

 

There are many different sizes of shelves available but I recommend you start with either a 2ft by 2ft or 2ft by 4ft shelve.

 

If you are limited on space then I recommend you get a 2ft by 2ft shelf, and if you have a lot of space like an empty closet or corner of a room then get a 2ft by 4ft shelf. Choose a shelf size Here.

 

You do not need a shelf if you are just wanting to grow just a few microgreens as an experiment.

 

If you are then just get a microgreen kit instead which will provide you with everything you need except a grow light to grow microgreens.

 

Although if you are wanting to grow a lot of microgreens indoors quickly and easily then you are going to need a shelf.

Grow Lights

 

A grow light is essential for growing lots of microgreens indoors unless you just want to use your window which is not always going to give your microgreens the right amount of light they need to thrive.

 

Growing microgreens by a window can cause them to become leggy and they may tip over and fall. Having a grow light will prevent that from happening and will provide your microgreens with adequate light.

 

There are many different types of grow lights to choose from. The main two options are LED grow lights and fluorescents.

 

Out of the two I recommend LED grow lights as they provide a full spectrum and that is what your microgreens need to thrive.

 

Fluorescents only provide blue light which will get the job done but in terms of efficiency and longevity LED grow lights are better.

 

If you opt for a 2ft by 2ft shelf then you are going to need an LED grow light that is the same length. The same goes for a 2ft by 4ft shelf.

Grow Trays

 

Grow trays are important for growing microgreens as they keep everything nicely packed together so that everything doesn’t end up like a giant mess.

 

The more growing trays you have the better because how many you need depends on how many microgreens you are going to grow.

 

I recommend growing trays that are 20 inches long and 10 inches wide.

 

Although you can choose whatever size you like, and there are many microgreens kits out there that provide grow trays of all sizes.

Seeds

 

The next items you are going to need are microgreen seeds.

 

There are many places you can choose to buy microgreen seeds but I recommend Sprout House Seeds and True Leaf Market as they have the best selection of microgreen seeds available.

 

Make sure you buy seeds that are specifically labeled microgreens just to avoid buying the wrong kind of seeds.

 

Even though microgreens are the same as their full-grown counterparts you still want to buy seeds that are specifically labeled microgreens as they usually come with more seeds.

 

There are many different types of microgreens to grow and some do need to be grown differently than others so I highly recommend you check out my How To Grow Microgreens selection which shows you how to grow 16 different types of microgreens.

 

You don’t want to grow all microgreens the same way as some do have longer germination times and some even need weight on top of them to grow straight and tall.

Growing Medium

 

There are many different growing mediums out there but I recommend you stick with Coco Coir as it’s less messy and doesn’t get all soggy like soil.

 

It retains moisture well and it’s sustainable and cheap! It comes nicely packaged in a small form factor and expands as you wet it.

 

Overall it’s my favorite growing medium to use but there are also different growing mediums as well such as paper towels and growing mats.

 

Paper towels are a great option but first make sure to use nontoxic paper towels that are free of dyes, inks, and fragrances so you don’t contaminate your grow.

 

Growing mats are another great option but can get expensive.

 

Overall what growing medium you choose to use is up to you. Experiment with different growing mediums to know which one you like best and then stick with that one.

How To Grow Microgreens Indoors

 

Before you follow along in this step-by-step guide, make sure you have all of the materials ready to go.

 

This will make the follow-along process so much easier.

 

Here is a recap of essential items you are going to need:

  • Shelving – Wired Shelves

  • Grow Lights – LED Grow Lights

  • Grow Trays – Microgreen Trays

  • Seeds – Sprout House or True Leaf Market

  • Growing Medium – Coco Coir

  • Spray Bottle

 

Step 1. Prepare The Growing Trays

 

Start with 2 10 by 20inch growing trays, or with whatever grow tray you decide to use. If you decide to use other grow trays then ignore this section.

 

One of the 10in by 20in trays will be beneath the other filled with water.

 

Do not do this yet, just place the one with drainage holes on top of the one that does not.

 

The one above will have drainage holes so the water can reach the roots of the microgreens.

 

This will prevent mold growth and overall just make the growing process so much easier.

 

Then fill the tray that has drainage holes with coco coir.

 

Then smooth out the surface and mist it well with a spray bottle.

 

If you don’t have a spray bottle then just sprinkle water over the coco coir until it is well moisturized.

 

Step 2. Plant The Seeds

 

Spread 2-3 tablespoons (or the amount shown in the directions) of your seeds evenly onto the coco coir.

 

If the seeds are not spread evenly this could cause overcrowding and a few other problems. So make sure not to add too much or too little!

 

Step 3. Water And Cover

After planting water the microgreens one more time, do not top the seeds with soil, just place another container on top to blackout the seeds and put some weight on top.

 

Yet again this does depend on the type of microgreens you are growing as some need weight and others don’t so do your research first.

 

Microgreens need humidity and dark to thrive. So set the microgreen tray in a place where it won’t get too hot, or too cold. 65 to 75 degrees Fahrenheit is ideal.

 

This begins the germination process. Spray seeds about 15 times once every 10-12 hours.

 
 

Step 4. Uncover And Give Light

 

After 3 days remove the top container and the microgreen seeds should have developed shoots.

 

The shoots may be yellow because of lack of light but this is normal and is nothing to be alarmed about.

 

Just set your microgreens under your LED grow lights and give them at least 12 hours of light every day.

 

You can buy an automatic timer to automatically turn the LED grow lights off and on but you don’t have to.

 

You can just leave the LED grow lights on all day, but if you want to reduce your electricity bill, then buying an automatic timer is something I recommend you do.

 

Now is the time to use the watering tray at the bottom of the container to avoid any soil from splashing onto the plants and to avoid mold growth.

 

Do not use the spray bottle anymore. To do this just simply grab the second tray that doesn’t have drainage holes and set it under the tray that is growing the microgreens and fill it slightly with water.

 

Always check up on the water levels every day to make sure the microgreens don’t dry out.

 

Step 5. Harvesting Time

 

Microgreens are usually ready to harvest in just 8 – 12 days. You’ll know when they’re ready to harvest when their true leaves start to appear.

 

This is after their first set of leaves, so once their second set of leaves start to appear they are ready to harvest. You can also taste test them to know whether they’re ready or not.

 

I did a complete guide on harvesting microgreens so check that out to learn a lot more about harvesting microgreens.

 

To harvest microgreens just simply use a pair of scissors or a knife and cut as close as you can to the coco coir to get the maximum harvest.
