How do you grow spirulina or chlorella at home? Which is easier?

I’ve a 20 litre plastic bottle which can function as a crude PBR. How can you make harvestible quantities of chlorella/spirulina in this. What are the nutrients and other conditions needed? Again,  is it possible to use the dried spirulina from capsules marketed? will they be useful as the starting culture?

    In my opinion Spirulina is the best species for DIYers as it is very easy to grow and harvest. The main advantage of Spirulina is that i it can tolerate any environment and can be harvested using a simple filter mesh or a cloth filter. Look at this video clipping to see how easily village women in India cultivate and harvest Spirulina for their own use - http://www.youtube.com/watch?v=U6cslNtc6P4
