Checking to see if my 5 month old phyto is still viable experiment . No smell/quick settling is observable. Used about 450ml of the phyto and filled rest of 2L with sw at 1.020. used 5ml of fertilizer. The pic makes it look darker than it is think of the color as a very pale greenish yellow.
11/27. What I noticed was the bottle on the right( 5 month old phyto) would culture but looked like it was a good 2-3 days behind the culture on the right (10/26 culture) but after about 4 days it caught up and now they look about even on day 6. So i think 5.5 maybe 6 months is about the longest a bottle of phyto stays alive
