After you let your culture acclimate in its new home after days of being in a shipping box, you can take your seed culture and split that culture into a jar.
You will now have two half cultures ready to add nutrient water to.
A nutrient kit from your farmer is essential. Follow the instructions and mix your powder and liquid nutrients in distilled water to create medium for your Spirulina,
Add nutrient water to both your initial bottle of culture and your new jar of culture. Allow a few days for the culture to regrow to its initial density.
From here repeat this process until you have at least four seed culture jars before you start a Spirulina System for production and harvesting.
