Seeds germinate at different speeds. Some may open within a few days while others take longer. Most viable seeds should show progress by approximately Day 10.

1. Place 10 seeds (more or less is fine) in a clean small Solo-style shot cup.
2. Add enough full-strength 3% hydrogen peroxide to completely cover the seeds.
3. Cover the cup with its lid.
4. Leave the seeds undisturbed and check every 4 days.
5. At each check, remove any seeds that have developed a visible taproot.
6. Gently rinse the sprouted seeds with filtered or distilled water, then move them into a moist paper towel.
7. Replace the solution around seeds that have not opened with fresh 3% hydrogen peroxide, cover again, and continue.
8. Repeat the process every 4 days as needed.

Use standard store-bought 3% hydrogen peroxide.

DO NOT DILUTE IT.

• No 1% dilution
• No 30-minute pre-soak
• No water mixed into the initial germination solution
• Do not mix hydrogen peroxide with any other chemicals or additives

The seeds remain in the 3% solution until they develop a visible taproot or until the next scheduled 4-day solution change.

• Use a clean Solo-style shot cup or similarly sized clean container.
• Place up to 10 seeds per cup.
• Add enough 3% hydrogen peroxide to fully cover the seeds.
• Cover the cup with its lid.
• Keep the cup protected from direct light and unnecessary disturbance.

Do not expect every seed to germinate at the same time.

One seed may open early while another seed from the same pack may take several additional days. This is normal.

Check the seeds every 4 days.

Most viable seeds should show progress by approximately Day 10, although individual germination times can vary.

At each 4-day check, look for seeds that have cracked and developed a visible taproot.

• Remove the sprouted seeds carefully.
• Do not pull or handle the taproot unnecessarily.
• Handle the seed shell whenever possible.

Once the taproot appears, that seed is ready to leave the peroxide stage.

Place the seeds that have developed taproots into a separate clean cup containing filtered or distilled water.

• Gently swish the water around the seeds.
• Pour off the rinse water.
• Do not aggressively shake or scrub the seeds.

The rinse removes residual peroxide before the sprouted seeds move into the paper-towel stage.

• Use a clean paper towel moistened with filtered or distilled water.
• The towel should be moist, not dripping wet.
• Place the rinsed sprouted seeds carefully into the towel.
• Protect the emerging taproot from unnecessary handling.

Continue until the taproot is developed enough for transplanting into your preferred medium.

Seeds that have not yet developed a taproot stay in the peroxide stage.

1. Discard the old peroxide.
2. Add fresh full-strength 3% hydrogen peroxide.
3. Make sure the remaining seeds are covered.
4. Replace the lid.
5. Check again in another 4 days.

Continue removing seeds individually as they develop taproots.

Once the taproot has developed sufficiently, carefully transplant the germinated seed into your preferred medium.

• Handle the seed gently.
• Avoid touching or damaging the taproot.
• Do not bury the seed excessively deep.
• Keep the young seedling environment moist but not waterlogged.

• Early: Some seeds may begin opening within the first few days.
• Day 4: First scheduled check.
• Day 8: Second scheduled check.
• By approximately Day 10: Most viable seeds should show progress.
• Seeds do not all germinate at the same speed.

A slower seed is not automatically a failed seed.

• Diluting the 3% peroxide during the initial stage
• Starting immediately in paper towels instead of following this method
• Allowing sprouted seeds to remain in peroxide after a taproot has developed
• Handling or damaging emerging taproots
• Using dirty cups, tools, or containers
• Using unnecessary additives in the germination solution
• Assuming every seed should germinate on the same day
• Discarding slower seeds too early

• Use only standard 3% household hydrogen peroxide.
• Do not ingest.
• Avoid contact with eyes.
• Do not mix with other chemicals.
• Keep out of reach of children and pets.

Our Germination Guarantee is based on customers following the SoLoud 3% Hydrogen Peroxide Germination Method outlined on this page.

To qualify for guarantee consideration, please use this method as written.
