what are your water temps? I read somewhere that anything over 70f hurts yield and growth, was wondering what you thought
It's a little tricky...
-Nutrients in your solutiion become more available (soluble) in warmer temperatures
-Dissolved Oxygen levels decrease as temperatures rise
-Pythium, aka. root rot, starts to grow at temperatures above 75*, along with other bacteria
-You
can use your nutrient temps to offset your environment temps- Im talking if it's winter out and your environment wont get above 65*, throw your res temp up to 72-73 area to compensate, it gives you less shock. And vice versa.
I never let my res go above 72-73 degrees, just to play it safe. 70's my sweet spot- they say 68, but I have also read an article called "Defining Stress" that goes into the different
kinds of stress we can put our plants through, for a positive outcome.
There is
Physical/Mechanical, and there is
Environmental/Abiotic
Steering towards
Vegatative
-Lower nutrient strengths, less Osmotic Pressure, easier uptake
-Warmer nute temp's
-Lower difference in Day/Night temps
-Air pruning
-LST
Steering to
Flower
-Nutes just under their max capacity, salts stress roots
-Worry your roots, lower water levels will make them think availabliity is limited, ie work harder
-Change nutes one hour after lights come on, Canna's Coffee
-Larger diff, gives more stretch.
These are just some notes I jotted down in my phone when I had read it... take it as a grain of salt. Again, I try to keep mine between 69-72*'s, constantly.
