Ever wanted fresh, crunchy greens without going to the market? Radish sprouts are one of the easiest foods you can grow at home. No garden, no soil, no stress. You can grow radish sprouts indoors in just 5 simple steps using only seeds, water, and a jar or tray. They’re ready to eat in 4–6 days, taste slightly spicy, and are packed with nutrients.
Step 1: Get good radish seeds
Start with sprouting seeds, not regular garden seeds. These are clean and safe for indoor growing.
What you need:
- Radish sprouting seeds
- A glass jar or shallow tray
- Clean water
👉 One tablespoon of seeds is enough for a jar.
Step 2: Soak the seeds
Put the seeds in your jar or tray and cover them with water.
- Let them soak for 6–8 hours (overnight works great)
- This wakes the seeds up and starts the growing process
After soaking, drain the water fully.
Step 3: Rinse and drain daily
This is the most important part.
- Rinse the seeds with clean water 2 times a day
- Drain all the water each time
- Keep the jar tilted or the tray slightly raised so water doesn’t sit
Too much water can cause a bad smell or mold, so good draining matters.
Step 4: Give them air and light
Place the jar or tray in a spot with:
- Fresh air
- Indirect sunlight (near a window, not harsh sun)
In a day or two, you’ll see tiny white tails. By day 3 or 4, green leaves start showing.
Step 5: Harvest and enjoy
Your radish sprouts are ready when they are about 2–3 inches tall.
- Give a final rinse
- Let them dry a bit
- Store in the fridge for up to 5 days
That’s it. You just grew fresh food at home.
