Food of the Future: Window DIY Spirulina Superfood
Thanks for the post. I just wanted to provide an update on affordable starter culture for anyone trying to do this affordably. A simple trip to ebay tells me that I can beat the price given for the product you linked. Here is a link to the search results on ebay. http://www.ebay.com/sch/i.html?_odkw=spirilina+cul...
A scientific paper from Indian Agricultural Research Institute, called Formulation of a low-cost medium for mass production of Spirulina, says: "Spirulina, being a non-diazotrophic cyanobacteriumrequires nitrogen in the medium, which is generallyprovided in the form of NaNO3." - MBogacz
It's my understanding that Spirulina uses atmospheric nitrogen. I haven't heard of it utilizing nitrogen in solution. - rockitaki
If I just want to use this for oxygen generation and I don't add the harvesting tube. Would that be a problem?
LOL We just added a Forum section to our website... A lot of good discussion going on there too. http://www.spirulinaacademy.com/forum/
you can find the full recipe to grow spirulina herehttp://www.spirulinaacademy.com/how-to-grow-your-own-spirulina-at-home-the-culture-medium/
You should never harvest more than 1/3 of your tank. Always keep 2/3 of the spirulina in your tank so they can grow over and over again and you can keep harvesting it for ever :)You can build a super easy secchi disk with a chopstick and a yogurt container to know how much spirulina you have in your tank. (here is how to do it : http://www.spirulinaacademy.com/how-to-measure-spirulina-density/)
"Fluctuations in the order of milliseconds between illuminated and dark zones have been shown to reduce light inhibition and increase biomass productivity (Ogbonna and Tanaka, 2000; Janssen et al., 2001). "Lähde: http://www.ncbi.nlm.nih.gov/pmc/articles/PMC3815273/
After harvesting and dehydrating, what would be the best way for long term storage with max nutritients retained? Canning it in the oven, mylar bag with oxygen absorber, or vacuum sealed bags
You can use wood ash in place of the nutrient mix for something more sustainable off-grid. You'll just need to keep an eye on the Ph level.
