Containers

I tried many containers to grow microgreens and all of them worked (some just took less work than others). This is a great place to get creative. Microgreens may be one of the few things you plant that will work in a large variety of containers. Here are some things to look out for when searching:

  1. A cover. This is to hold the moisture in so your seeds can germinate. The Jiffy Greenhouse Kits all come with a transparent cover, which solves this issue. But you can also create a cover by adding plastic wrap to the top of the container or flipping a container of the same size on top of the one your planting in.   

  2. Depth. The goal should be using just the right amount of soil for each planting. More soil will hold more water, but will cost more in the long run.

  3. Drainage. A container that holds water instead of letting it pass through will promote mold and disease. I prefer the container my seeds are in having drainage holes. You can more accurately control the amount of water in your soil. 

  4. Size.  When growing indoors, you may have limited space.  A shelf, a table, or even just a windowsill.  Microgreens can work in all of these, but you'll need to choose the container to fit your space.

  5. Food-safe.  I'm growing my food in this container, it needs to be free from harmful chemicals and non-food-safe materials.

5x5 growing trays - My favorite because it outputs the right amount of microgreens for my family. I grow a variety of microgreens for different recipe uses, and this works perfectly.

10x10 growing trays - A versatile option since you could grow four 5x5 crops in this or one larger crop if you need a lot of one type of microgreen.

10x20 growing trays - A standard among commercial microgreen farmers, this maximizes your harvest.  

Jiffy Windowsill Greenhouse - This is ideal for growing in a sunny window and comes with a humidity cover. Perfect for a few servings of microgreens.

Food containers - The containers that salad greens and pastries come in at the grocery store can be perfect for microgreens.  They come with covers and are fairly sturdy.

Many containers will work. I’ve even used bonsai pots. These containers are just convenient for me because they are quick to set up, available locally, and cheap,

Growing microgreens can be an easy low-cost activity if you look for your materials in the right places. Let’s upcycle some of your plastic containers from the grocery store to grow your own fresh food in the form of microgreens.

When I started growing microgreens, one of my first questions was "What do I plant these in?"  I've been gardening for a while, and I love using recycled plug-type containers for my seeds.  That didn't quite fit with microgreens.  

Microgreens are planted with a high density because you are trying to get as many plants as possible to grow in a small area.  Contrary to everything I knew about gardening.  So, naturally, a lot of the options for seed starting that you find in stores aren't necessarily great for microgreens.  

What is a grow light?

A grow light is simply a light designed to mimic the sun.  Indoor lights like soft white bulbs put out light on the red end of the spectrum, closer to the look of candlelight. But grow lights give off full-spectrum light that is red, blue, and green. There are two main types, fluorescent and LED.
