I run recirc DWC with top feed so my system runs 100% of the time. After looking in google images it appears your running a (very) similar set up just with less flexibility and plumbing. As my plants grow I can move them farther apart. You are limited by your size of the tray that sits above...
Yes your on the right path there is no way to determine what the plants are using. Some people recommend topping off with PH water only. I think this is a good starting point if your new to hydro.
Here is some basic info for starting in hydro.
Get some good monitors to track PH,PPM, and Water...
I just ran out of PH Down and ended up getting GH down. Ironically I get .07 shift per drop per gallon( 14 drops a point PG).
My ph has been very stable since I've been using it.
Just curious hydroton or rock wool?
For the chlorine I add a dechlorinator slightly less than what the manufacture suggests, and let the air stones knock out the rest.
If you don't want to buy the dechlorinator just add airstones to your holding container. Should only take a few hours VS a day.
I have to totally agree nutes first then PH. Also make sure you are diluting your PH additive before adding to control bucket to avoid nutrient knock out. Even when I dilute mine as per the manufactures specification, I sometimes see slight clouding. Doesn't seem to do it when I use the PH...
Does anyone know how liquid air is made?
Air is compressed and a heat exchanger reduces the ambient temperature. The air is then released into a chamber cooling the air even more. (Not going into how the valving is configured)
This process is repeated until the air temperature reaches -320F This...
