THE MANUAL
7 steps to a fresh harvest
After about 10–14 days, your spirulina is ready for harvest – often a little quicker in summer, a little slower in winter. For maximum yield, wait for a rich dark green color.
Set up harvest assistance
Place the tripod in the sink and securely position the supplied filter on it.
Filter spirulina
Slowly pour the remaining spirulina culture through the filter. The valuable spirulina mass will remain completely in the filter.
Rinse briefly
Briefly rinse the filtered spirulina with clear water to remove any residual nutrient salts.
Skimming off the harvest
Spoon the fresh spirulina into the supplied spirulina jar and place it directly in the refrigerator.
Clean the grow glass
Clean the grow jar thoroughly with hot water. The jar is dishwasher safe.
Restart farm
Reseed the farm immediately with the saved 250–500 ml culture. This time, use 2.2 L lukewarm water and 45 g nutrient salt.

CONSISTENCY
The perfect harvest consistency
CONSISTENCY TIP
Creamy instead of dry.
After rinsing, don't let the spirulina drain completely. It should remain nicely creamy-moist and not turn into a dry paste.
Easy to portion
The creamy consistency can be easily scooped from the filter into the spirulina jar.
Store in a cool place
Immediately place the finished harvest in a sealed container and refrigerate it.

FURTHER QUESTIONS
Storing Freshness Properly
Everything you need to know about the shelf life, storage, and a simple freshness test for your home-grown spirulina.
How long does freshly harvested spirulina last and how should it be stored?
Freshly harvested spirulina lasts about 7 to 8 days in the refrigerator. It's best to store it directly in the provided spirulina jar or another tightly sealed container.
For longer shelf life, you can easily freeze fresh spirulina. You can tell if it's still good by its smell: as soon as it smells unpleasant, you should no longer consume it.
