It is super simple, trust me! You will need:

Place the rocks first (below the soil), so the water can drain down under the soil, and the roots won’t rot. Then, fill the jars with soil, more than halfway.  

Next, carefully place the herbs in the jars and pat them down with your fingers. 

The hardest part is to keep them alive. Make sure to do further research in case you do your indoor herb garden!

Jars are my to-go when I’m shopping in bulk. I use them for oats, grains, cocoa powder, chocolate, and almost anything!

29. Growing sprouts

Sprouts are great, healthy, and flavorful additions to your salads or meals. But the store-bought always comes in plastic. 

Luckily, making sprouts at home is easy, and all you will need is: 

  • a mason jar 
  • sprouting seeds
  • fine mesh strainer/cheesecloth 


  1. Place 1-2 tablespoons of the sprouting seeds in a mason jar. Cover with about two inches of warm water, and let it sit overnight.
  2. The next day, use the cheesecloth to drain the water. Add water to the jar to rinse the seeds, and drain again.
  3. Repeat this twice a day, every day, until your sprouts get a bigger size. It will take between 3 to 7 days, depending on the type of sprout you’re growing. 

Keep in mind that:

  • the sprouts are best when they are still fairly small and just starting to turn green. 
  • it is best to store them in a covered bowl
  • you should use the sprouts within a week
