well. I'm clumsily attempting Barr's concept of intentionally
overdosing and clearing out the excess with weekly water changes. I
don't have a lot of local resources for stuff like hydroponics - here
in Maine we grow our pot the old fashioned way, in well tended fields
and gardens, so not much call for hydroponics stuff.


http://www.gregwatson.com has all the stuff for Conlin-Sears or Barr EI
fertilization. IIRC, Conlin-Sears went with limiting phosphate. EI
limits nothing (maybe iron) but calls for biofiltration that removes all
the ammonia.

Yeah - I didn't mention that I got to Conlin-Sears from gregwatson
from Barr. gregwatson is where I felt the nudge to start putting it
all together. In other words, been there done that and will surely
return at least a few more times.

You're correct on the C-S limit phosphorus - every time they added
phosphates, they got massive algae attacks.
