Merry Christmas all
So you seriously wrote all that and are franticly worried about people running 9 ppm of DO instead of 10 ppm?? Did you even read the chart you posted? Thats what it says your talking about - the difference between 60 f and 70 f is 1 PPM of DO.
The funny thing is that i haven't recommended anything at all, i simply stated the facts about plant physiology and chemistry so that people can understand what happens in there system rather then (as some people seem to want to do) simply holding onto marginal success for dear life.
The truth is that i both run and recommend temps lower then you are talking about to begin with. I recommend 60-62 and run 50-60 actual, but i do it for rot prevention which is the paramount parameter in this system for water temp indication.'
That, however, doesn't change the fact that both biological and chemical recaions take place at higher temps and that the best temps for explosive growth are going to be 68-72.
Sorry if the nuance of this is over your head, but i can see how you could be confused; as greenhouse water temps are extremely "high" and the "aricle" you posted never actually gives a "number" for temperature, just talks about "high" and "low".
At any rate, since all of this arouse out of a simple few lines indicating that a chiller stall, if fixed before rot takes hold, should be no problem: How are he girls looking? Good i hope?
You might be able to get away with it seeing as your already at week 2-3, but be careful.
Possibly double up on your root rot prevention applications?
