The Science of Sand and Microgreens

The microgreen is a small vegetable green, about 1–3 inches tall. They have an aromatic flavor and a concentrated content of nutrients, which are found in various colors and textures. Microgreens are not a specific kind of plant — they can come from different species like radish, mustard, or beet.

Conversely, sand is a granular material composed of finely divided rock and mineral particles. It is defined by its size, being finer than gravel and coarser than silt. And while it might not seem like an ideal medium for growing plants, it has certain qualities that make it a good candidate for growing microgreens.

Sand is excellent at retaining heat, drains well, and can be easily sterilized between plantings to reduce disease risk. It’s also an inert medium, meaning it contains no nutrients. You have complete control over the nutrients your microgreens receive, leading to healthier, more robust plants.

The Art of Growing Microgreens in Sand

Growing microgreens in sand might seem daunting initially, but with some knowledge and practice, it can become second nature. Here’s a step-by-step guide on how to do it:

Choose Your Microgreens: Start by choosing the type of microgreens you want to grow. Some popular options include radish, broccoli, and arugula. Each type has its unique flavor and nutrient profile, but arugula is easy to grow.

Experiment and Have Fun: Don’t be afraid to experiment with different types of microgreens and growing conditions. Growing microgreens is as much an art as it is a science, so have fun with it!

Prepare Your Sand: Next, you must prepare your sand. Start sterilizing it to kill potential pathogens by baking it at 200 degrees Fahrenheit for about 30 minutes. Once it’s cool, place it in your growing tray.

Choose the Right Sand: Not all sand is created equal. For best results, choose coarse sand, like builder’s sand. Avoid fine sand, as it can compact and hinder water drainage.

Plant Your Seeds: Sprinkle your microgreen seeds evenly across the surface of the sand. You don’t need to bury them—press them gently into the surface with a spatula.

Feed Your Microgreens: Since sand is an inert medium, you’ll need to provide your microgreens with nutrients. You can do this by watering with a diluted liquid fertilizer.

Germination: Water your seeds lightly. You want the sand to be damp but not waterlogged. Then, place your tray in a dark location for the seeds to germinate. Most microgreens will start to sprout within 1-3 days.

Provide Adequate Light: Microgreens need plenty of light to grow. Place your tray near a sunny window or under a grow light if you’re growing indoors.

Water and Wait: Continue to water the seeds. Once germination happens, place your tray in a sunny spot and wait for photosynthesis to take over. Most microgreens will have their first leaves in 5-6 days.

Water Wisely: Overwatering is a common mistake when growing microgreens. Remember, the sand should be damp, not waterlogged. Water lightly and regularly to keep the sand moist.

Harvest and Enjoy: Once your microgreens have grown their first set of true leaves, they’re ready.

This method of growing microgreens in sand is simple and sustainable. It allows you to reuse the sand multiple times, reducing waste and saving money. Plus, it’s a great way to grow fresh, nutritious greens, even living in a city apartment with no garden space.
