man.. i have to stop smoking...
i see what you mean. like when to feed more times per day. i have to get that one time a day wet/dry cycle out of my head, fuck..
just did my feed. in was ph 5.9 ppm was 490 out was 6.0 and 620
while i was working i was thinking out how you not battle ppm. u let it rise by using less.... fuck. and how adding water while change the ph
ive never done a recirculation system. all hand water. would always just mix and feed
this takes planning allowing it to increase without fighting. and thats what it feels like everyday, a fight to keep it in balance
Now you are starting to get it :cool: Aside from the runoff being extremely high before I would stop paying attention to runoff numbers at this point and start paying attention to the plants. You don't need to check runoff EC and pH numbers in a drain to waste style grow. Except for extreme cases it's never a true representation of your mediums numbers. If you feed low and often things stabilize and you don't have to ever check runoff again.
In a recirculation system you just monitor the rez. The idea is fairly simple. Generally if the pH drops and EC rises you top off with water to get the levels back to normal as the plants don't want that much. If the pH rises and the EC drops you top off with nutrient to get the levels back to normal because the plants want more.
Wet/Dry cycles are for soil because it retains so much water compared to air. It has a higher potential to go anaerobic. EC spikes can still happen in soil when using hydro nutrients haha. That's why I'm not a big fan of the hybrid approach. Too many variables IMO. I like either hydro with mineral salts or soil amended with organic inputs for the microbes to break down and plain water.
