Aleluia, finally got it... cost me almost an arm and a leg but finally got it.
I want to thank for all the help I got here because I bought many times before spirulina delivered in the mail but always arrived dead and smelling like rotten eggs, this time had to do a long, time, money and effort consuming trip into unknown lands to to meet a spirulina grower in person and then carry a 5 liter bottle in my lap back home as fast as possible to put it quickly into the growing medium in less than 10 hours. Also tried growing a batch that I harvested myself two days before departing but was nearly dead when I arrived home and also placed it in the growing medium.
My first goal now is learning how to keep it alive and I am still experimenting with different kinds of nutrient solutions at different concentrations with different environments, etc, etc...
but I already found 2 kinds of nutrient solutions that are producing well and everyday I harvest half of this floating layer on a daily basis and next day is full again
I use two bottle like that to start new cultures and to compensate for the ones that die by mistake of mine and this next one I started yesterday and today it is already visible around the borders a layer of spirulina growing thick:
And for what I've seen I'm getting approximately 10 per cent of straight filaments... so, it is not so hard to harvest
Tomorrow or maybe after tomorrow when I have time let's start the excavation of a
pond for growing spirulina.
...
Ufff... finally...
it was almost 1 year that I spent running around to catch this green thing.
