THE STEP-BY-STEP GUIDE
Step 1: Prepare the beans and bottles
Take your plastic bottles and remove the labels. Rinse them with warm soapy water and rinse them again with clean water. This step is essential to ensure that your sprouts remain free of any contaminants. Using scissors, cut off the top of each plastic bottle. This will create a small container for your sprouts, allowing for adequate air circulation.
Now, take your dried mung bean or soybean seeds. For 1 liter bottles, you will need approximately 1-2 tablespoons of seeds, and for 2 liter bottles, you will use 2-3 tablespoons. Wash the seeds well in cold water to remove any dust or debris.

Step 2: Distribute the beans
Place the washed seeds in a container or bowl. The seeds should be covered with enough water and left to soak for about 8-12 hours or overnight. This process helps initiate germination.
After soaking, you must drain the seeds and distribute them evenly in the cut plastic bottles. It is essential not to crowd the seeds, a single layer of seeds being sufficient. This way, each sprout will have room to grow.
Step 3: Cover with lids and towels
Attach the lids to the plastic bottles you cut off earlier. To do this, you can use bottle caps or a piece of plastic wrap secured with an elastic band. Place the bottles in a dark, cool place, such as a cupboard or pantry. Cover them with a clean, damp kitchen towel to keep the environment moist and dark – ideal conditions for germination.
Step 4: Watering and draining
Twice a day, carefully remove the cloths and turn the bottles upside down over the sink. Allow excess water to drain completely. This step helps prevent the growth of mold or bacteria. Now return the bottles to their dark, cool place, recover them with damp towels and continue the process of rinsing and draining twice a day.

Step 5: Harvest the sprouts
In about 3-7 days, depending on the temperature and the type of beans you have chosen, your bean sprouts will be ready to be harvested. They should be about 2-3 inches long and a pale yellow color.
To harvest, remove the lids or plastic wrap from the jars and expose the sprouts to indirect sunlight for a few hours. This step will allow them to develop some chlorophyll and turn green. Then, using scissors, cut the sprouts just above the seeds, as the lower part can be a little hard. Wash the sprouts well in cold water to remove any remaining seeds.

HAVE IN MIND
- Maintain darkness
Germination bottles should be placed in a dark place during the early stages. This favors the appearance of longer shoots without much chlorophyll. When they are almost ready to harvest, expose them to indirect sunlight to make them greener. - Correct drainage
Make sure bottles drain well after each wash. Excess moisture can lead to mold growth. If you find that your bottles are not draining properly, consider drilling some small holes in the bottom to facilitate drainage.

- Temperature
The ideal temperature for germination is around 21°C. If your home is colder, sprouts may take longer to grow, while warmer temperatures can speed up the process. - Clean harvest
When it’s time to harvest, make sure you’ve cleaned all the remains of the seed husks. These can be slightly bitter and affect the flavor of the sprouts.
Congratulations, you managed to grow your own bean sprouts! Now, you can enjoy them in salads, sandwiches, stir-fries or any way you prefer. Not only is it a fantastic way to add fresh, healthy ingredients to your meals, it also reduces your environmental footprint.
