How to Grow Sprouts at Home: A Beginner’s Guide for Fresh and Crunchy Goodness
Sprouts are a fantastic way to grow fresh, nutritious food on your kitchen counter. Packed with nutrients and requiring only a jar, screened lid (or cheesecloth), some water, and seeds, sprouts are quick to grow and add a lovely crunch to salads, sandwiches, and stir-fries. Today, we’re walking you through how to grow alfalfa sprouts—one of the most popular and beginner-friendly options. While we have chosen alfalfa sprouts, you can use the techniques we discuss here to grow almost any sprouts. Let’s get started with everything you need to grow fresh, crunchy sprouts at home!
Methods of Growing
As with most things in life, there are many different ways to accomplish a task, and sprouting is no different. The most common methods used for sprouting seeds are the jar, tray, and bag methods. In this guide, we will focus on sprouting our delicious alfalfa sprouts using the jar method, but to give you a broader perspective, here’s a quick look at all three popular methods for sprouting seeds that you might find useful and informative.
Jar Method- This is one of the most popular ways to sprout seeds because it’s simple, inexpensive, and uses items you probably already have at home. You soak the seeds in water overnight in a glass jar, cover the top with a breathable lid (like a cheesecloth or a sprouting lid), and then rinse and drain the seeds 2-3 times daily until they sprout. The jar creates a compact, moisture-rich environment perfect for sprouting. It’s a great beginner-friendly option that works well for small to medium-sized seeds like alfalfa, mung beans, or broccoli.
Tray Method- This involves spreading seeds across a flat tray, often lined with soil, a growing medium, or simply left bare, depending on the seed type. The tray method is ideal if you’re sprouting larger seeds or growing microgreens because it gives the sprouts room to spread out and grow evenly. Trays are often stacked for efficiency and airflow, and seeds are kept moist by misting regularly until the seeds sprout, then watered from the bottom after sprouting occurs. It’s a little more space-intensive but perfect for urban farmers looking to scale up their sprouting game.
Bag Method-This method uses a breathable bag, typically made of cotton, hemp, or other natural fibers, to sprout seeds. The seeds are soaked and then placed in the bag, which is hung up or set in a well-ventilated space. You rinse the bag a couple of times a day and let it drain well between rinses. This method is great for travelers or those short on kitchen space since it’s compact and portable. It’s especially suited for hearty seeds with hearty roots like lentils, mung beans, or chickpeas. Delicate sprouts should not be grown in bags because they cannot handle the bit of tumbling needed during daily rinsing.
Each method has pros and cons, but the jar method is a classic for a reason—it is simple, effective, and gives you a front-row seat to observe the magic of sprouting! For this reason, we will use the jar method to sprout.
Essential tips for all seeds and sprouting methods:
Sanitation is Key:
Clean Equipment- Always use clean jars and utensils to prevent contamination. Regularly washing and sterilizing your sprouting jar can greatly reduce the risk of bacterial growth.
Quality Seeds- Purchase seeds specifically labeled for sprouting to ensure they are free of contaminants and pesticides.
Environmental Considerations:
Temperature- Keep your sprouting jar in a place with a moderate temperature (ideally around 65-75°F or 18-24°C). Extreme temperatures can slow down the sprouting process or encourage unwanted bacterial growth. In addition to bacterial growth, temperature fluctuations can affect harvesting times. In general, cooler temperatures mean longer growth times, while warmer temperatures mean shorter growth times.
Light Exposure- Alfalfa sprouts do best in indirect light. Too much direct sunlight can dry them out, while complete darkness might slow down the sprouting process. While the seeds are sprouting, keep them in darkness to encourage them to sprout. After they have sprouted windowsill with filtered light is typically ideal.
Maintenance & Storage:
Only soak sprouts for as long as instructed. Soaking too long can kill the seed, and it will not grow.
Remove excess water after rinsing. Not doing so can promote bacterial growth.
Use a salad spinner and paper towels to thoroughly dry your sprouts before storing them.
Alfalfa Sprouts Using the jar method
Step 1: Gather Your Supplies
What you’ll need for an easy sprouting setup:
A wide-mouth glass jar, such as a classic 32 oz mason jar, will serve as your ideal sprouting container. This type of jar is perfect for allowing ample air circulation while also providing enough space for your sprouts to grow freely.
Sprouting lid or cheesecloth: A sprouting lid, often referred to as a mesh lid, or a piece of cheesecloth can be effectively used when secured tightly with a rubber band for the purpose of draining excess water.
Sprouting seeds is an exciting and rewarding endeavor: Look for seeds that are specifically labeled for the purpose of sprouting. Alfalfa is a fantastic choice for beginners due to its ease of growth and delicious flavor, but you might also find mung beans, broccoli, and radish to be excellent options worth exploring, as they too offer great taste and nutritional benefits.
Container to catch water: After rinsing, there will be a little water left over. Use any container that will catch the water and keep the area clean.
Clean water: You’ll need fresh, cool water to thoroughly rinse and soak your sprouts daily for optimal growth. Most of us will need to use filtered water to ensure it's safe, but if you have direct access to clean and uncontaminated water, feel free to use it without a filter for your sprouting needs.
Step 2: Add and Soak the Seeds
Start by adding about 1-2 tablespoons of alfalfa seeds to your jar. Remember, a little goes a long way when it comes to sprouts—they’ll expand significantly as they grow! It’s also a good idea to document the precise amount of seeds you use so you can easily make adjustments in the future if needed. Keeping a little journal of your sprouting adventures can help you perfect your process!
Fill the jar about halfway with cool, fresh water, then cover it securely with either the special sprouting lid or a piece of cheesecloth. Allow the seeds to soak patiently for 6 to 8 hours (soaking time varies based on the seeds, so follow the recommended sock time provided by the retailer), giving them just the right amount of time to absorb the water and start their sprouting journey.
Soaking seeds helps wake them up and kick-starts the sprouting process, ensuring that they’re fully prepared and eager to grow. After you’ve finished soaking, be sure to drain the water completely.
Step 3: Rinse and Drain
After the initial soak, it’s time to embark on a daily rinse routine that will set you on the right path. Being consistent and diligent with your rinse routine can make the difference between harvesting fresh, crisp, and flavorful sprouts versus ending up with soggy, inedible ones. Here are a few simple yet effective steps to ensure that you achieve an excellent and bountiful harvest of sprouts:
Rinse at least 2-3 times daily.
Rinse thoroughly. Fill the jar with cool water, swirl gently, and drain completely. This is very important! Leaving excess water in the jar could encourage bacterial growth. The sprouting lid or cheesecloth will also facilitate easy draining. These two process components are essential to avoid sogginess and prevent mold growth.
After each rinse, be sure to place the jar at a slight angle to ensure that any extra water drains out properly. This simple method also allows proper airflow to circulate within the jar, which is essential for maintaining the freshness of your sprouts.
Tip: After giving the seeds a good rinse, allow them to sit comfortably on the top and along the sides of the jar. This will help promote airflow and give them ample room they need to grow. They will naturally tend to cling to the sides during the first few days, so it’s perfectly fine to let them do that.
Step 4: Let Them Sprout!
Place the jar carefully out of direct sunlight to ensure the best environment for sprouting. After just a day or two, you'll be amazed to see tiny little sprouts start to emerge! Continue with your daily rinse and drain routine consistently, and enjoy the excitement of watching your sprouts grow just a little more each day. It's a wonderful process that invites patience and nurturance!
By day 4, you can move the jar to a brighter spot to speed up greening the leaves, beginning photosynthesis, and adding chlorophyll to your sprouts. This step is optional, and many prefer to leave the leaves on the yellow side for a more sweet and tender flavor. If you decide to move them to bright light, never put the jar in direct sunlight. It is too intense for the tender sprouts and could burn them. After a day or two, they should be ready for the final step, with seed hulls detached and tender green leaves just starting to open up. You’ll know they’re ready when they’re about 1-2 inches long and a nice light green.
Step 5: Final Rinse and De-Hull
On the final day, give your sprouts one last rinse and check for any leftover seed hulls (the seed’s outer shell). Gently fill the jar with water, swirl, and let the hulls float to the top. You can pour them out, or scoop them off with a spoon. If your jar is filled to the brim with sprouts, put them in a large bowl, gently swirl, and let the hulls float to the top and rinse.
Eating the hulls won't hurt you, as they are perfectly safe to consume, but taking the time to remove them gives your delicious sprouts a fresh, clean look and a delightful texture that enhances your culinary creations.
Step 6: Harvest and Store
Your delicious sprouts are finally ready to enjoy and eat! For immediate use, give them a quick final rinse under cool water, drain them thoroughly, and gently pat them dry with a clean towel. If you’d like to store them for later use, carefully transfer them to an airtight container lined with a paper towel to help keep moisture in check, then place the container in your refrigerator. With this method, they’ll stay fresh, crisp, and delightful for up to a week, allowing you to savor them in various meals!
