2. Sprouting Container:
You have several options here:
- Sprouting Jar with Mesh Lid: This is a popular and affordable choice. The mesh lid allows for easy rinsing and drainage. (We recommend this Sprouting Jar Kit)
- Multi-Tiered Sprouter: These stackable trays allow you to grow multiple types of sprouts simultaneously.
- DIY Options: You can even use a clean glass jar with cheesecloth secured with a rubber band. Perfect for those learning how to grow sprouts, who don't want to invest in new seed sprouter equipment.
3. Kitchen Basics
- Clean Water: Use good quality, non-chlorinated water for soaking and rinsing your sprouts.
- A Well-Ventilated Area: Sprouts need air circulation to prevent mold growth.
- Indirect Light: While sprouts don't need direct sunlight like mature plants, some indirect light is beneficial for chlorophyll development and a greener sprout.
- Measuring spoon
- Paper towels or a breathable cloth
Step by Step: How to Grow Sprouts Indoors
Now for the exciting part – the official step-by-step guide on how to grow sprouts:
Total active time: 2–3 minutes per day
Harvest window: 3–7 days (depending on seed type)
Step 1 – Measure & Rinse
- Add 2–4 Tbsp of sprouting seeds to your jar or tray.
- Rinse thoroughly with water.
Step 2 – Soak
- Cover seeds with cool water (about 3× seed volume).
-
Soak times:
- Small seeds (alfalfa, clover): 4-6 hrs
- Larger seeds (mung, sunflower): 8–12 hrs
Step 3 – Drain & Position
- Drain water completely.
- Place jar at a 45‑degree angle mouth‑down to ensure airflow and prevent standing water.
- From here, your jar or seed sprouter will either need to be put somewhere dark (eg. cabinet) or placed in indirect light. Follow instructions for your specific seed type.
Step 4 – Rinse & Repeat
-
2-3 times daily, fill jar with cool water, swirl gently, and drain.
Quick tip: Do it after breakfast and dinner—easy to remember.
Step 5 – Green Them Up
- Depending on seed type, once tiny leaves appear (usually Day 3–5), you can move sprouts into indirect sunlight for a chlorophyll boost.
- Avoid direct midday sun that can overheat or dry them out.
Step 6 – Harvest
- When sprouts reach 2–3 inches (alfalfa) or when first true leaves appear (sunflower), give a final rinse to remove any seed hulls.
- Spin dry in a salad spinner or pat with paper towels to remove moisture.
Step 7 – Store
- Refrigerate in a breathable container.
- Enjoy within 5–7 days for maximum crunch and nutrition.
🙌 And that's it! In just 7 easy steps and a few minutes a day, you'll have fresh, nutrient-packed sprouts to add to your healthy lifestyle!

Tips for Successful Indoor Sprouting
To ensure your indoor sprouting endeavors are successful, keep these helpful tips in mind:
🌱 Start Small:
When you're just learning how to grow sprouts, begin with a small batch of one type of seed. This will allow you to get the hang of the process before trying multiple varieties.
🌾 Use Quality Seeds:
Invest in high-quality, non-GMO sprouting seeds from a reputable source like Seedboy. Seeds intended for planting in soil may not be suitable for sprouting.
🧼 Maintain Hygiene:
Clean your sprouting containers thoroughly between batches to prevent contamination.
💧 Ensure Good Drainage:
Excess water is the enemy of healthy sprouts. Make sure your container allows for proper drainage.
🍃 Proper Ventilation:
Good air circulation is essential to prevent mold growth. Avoid placing your sprouter in a stuffy or humid environment.
👀 Observe Carefully:
Pay attention to your sprouts daily. When learning how to grow sprouts, it's important to look for any signs of mold or unusual odors. If you notice anything concerning, discard the batch.
📏 Don't Overcrowd:
Give your seeds enough space in the sprouting container to allow for proper growth.
🧪 Experiment!:
Once you've mastered the basics of how to grow sprouts, try different types of sprouting seeds to discover your favorites.
Troubleshooting & Safety Tips
If You See Mold…
- Most fuzzy “roots” are harmless root hairs. Mold smells musty and appears in patches—discard and start over.
- Improve airflow: spread seeds thinner or switch to a ventilated seed sprouter.
Off Smell or Slimy Texture?
- Increase rinsing frequency or lower room temperature.
- Sterilize gear with vinegar between batches.
Maximizing Germination
- Buy fresh, lab‑tested sprouting seeds(Seedboy Sprouting Seeds undergo rigorous quality testing for things like Salmonella & E. coli, to ensure the highest standards of purity, cleanliness & safety.)
- Store seeds in a cool, dark place.
Following these safety measures will help you avoid pitfalls when learning how to grow sprouts!

Seed Spotlight: How to Sprout Sunflower Seeds
Sunflower shoots are thicker and heartier—perfect for avocado toast.
Step 1:
Add black oil sunflower seeds to a sprouting jar and soak for 8-12 hours.
Step 2:
Drain & rinse the seeds with cool water.
Step 3:
Invert the sprouting jar and cover with a cloth or place in a cupboard. We want to keep the seeds in darkness for the first 2 days to encourage strong stems.
Step 4:
Rinse and drain the seeds twice daily with cool water. Always invert the sprouting jar after to allow for drainage.
Step 5:
Uncover on Day 3 and expose to indirect sunlight. This will allow your sprouts to green up and get a little chlorophyl boost!
Step 6:
Harvest when cotyledons are flat and vibrant—around Day 7–8.
📌Pro Tip: Snip sunflower sprouts with scissors rather than pulling to keep hulls separate and your kitchen tidy!
