Event Focus: Inspecting Farmer-Level Homestead Korean Spirulina Production (কৃষকের বসতবাড়িতে কোরিয়ান স্পিরিলুনা উৎপাদন পরিদর্শণ)

Having worked extensively on *Spirulina* (*Arthrospira platensis*) cultivation and awareness in Bangladesh, one of my most rewarding field visits in South Korea was inspecting farmer-operated homestead Spirulina production facilities.

Korean Homestead Spirulina Bioreactor Facility On-site inspection of hygienic, enclosed Spirulina cultivation tanks operated at the farmer homestead level in South Korea.

Closed-Loop Greenhouse Spirulina Culture Vessels Examining aeration, optical density, and alkalinity control inside a Korean family-run Spirulina greenhouse.

Value-Added Korean Spirulina Functional Products Direct-to-consumer packaging and quality control protocols used by Korean smallholder Spirulina producers.

Key Takeaways for Decentralized Microalgae Farming

• Contamination-Free Closed Tanks: Unlike open outdoor ponds vulnerable to dust and monsoon rain dilution, Korean homestead growers utilize translucent cylindrical tanks and greenhouse-enclosed channels with automated air-lift agitation.
• Automated Temperature & pH Regulation: Maintaining optimal carbonate-bicarbonate buffer conditions (pH 9.0–10.5) and water heaters for year-round strain purity.
• On-Farm Value Addition: Processing fresh Spirulina biomass immediately into freeze-dried powder, tablets, and functional beverages for high-margin local retail.
