nannochloropsis phytoplankton culture (questions)

[phyto4life]

thanks

I'll start 2 x 1G going with 1/4 tsp of fertilizer and i'm thinking of splitting it after 4 day's

after that when I split them again I might leave them a little longer and add more fertilizer

do you use a density stick and if so do u know the density I would be going for that will leave vary little fertilizer with the max amount of phyto cell's?

or a shade of green?
