How To Grow Spirulina at Home - Indoor Spirulina Cultivation Setup 

Instead of the plastic lids on the bottles, I've seen a number of successful growers stuff a small amount of cotton fabric into the opening. It serves the purpose of keeping out insects and other contaminants, but it's much better at letting air out - and if you're pumping air in, you do need to allow the same amount of air out.

Also, if you can get your spirulina photosynthesising the carbon dioxide in the air you're bubbling through their tanks rather than the carbonate from their nutrient solution, you'll want to keep the door open to the rest of your house, or else a fan to circulate the air. Any photosynthesising plant will eat the carbon dioxide you're exhaling and give you back clean oxygen in exchange and this will work wonders for your indoor air quality - and therefore, for your family's health.

although i don't speak Tagalog i think you for the video can you let me know how many minutes do you run the air pump and home many times each time ?

Sir ok ba ang nutrient solution gamitin oara sa chlorella sp?
