Algae Culture Porphyridium Cruentum, Perfect for School Science Fairs/Projects, Experiments & Classrooms (1.7mL)

Algae Research Supply is providing high-quality Spirulina, a safe algae organism that can be consumed after proper harvesting and preparation. The company offers no guarantee of the product's safety because it depends on how it has been grown. The algae belongs to the species S. Platenais, and without adding nutrients, the algae can double its growth in five days. The product has enough nutrients to fill a five-gallon tank, and an infinite supply can be obtained if properly grown. The user will have to add animal feed grade urea, rock salt, baking powder, wood ash, and iron in proportionate measurements every time they harvest. The culture requires bubbling or stirring, i.e., mixing to grow, for which the user needs an air pump or water pump. The density of this algae culture is at least 0.4g dry weight per liter, and it can go up to 0.7g dw/L. The company ships the order on Mondays, Wednesdays, and Fridays throughout the USA.
