Makes me wonder how long it takes for the water in the upper pot to be consumed. Or maybe it just takes a while for the newer h20 to mix and then finally take the place of the old h20 in the growing medium…? The rez is easy, as you you replenish it, it kinda is what it is right? Really anxious to get your input on the jacks nutes. I have a bunch of other stuff as far as nutes id like to run by you also. Just want to make sure that its the kinda stuff i should be putting into the octos since this would indeed be my first run with them. Obtw, sorry, I work nights so its not always easy to catch up with your thread, but i am watching closely… Shit, you more than chris are the reason i have decided to go this route… Thanks a million in advance!
