I think you're right. It's 4" and stubby. It's working OK for now, but may be close to saturation. Just starting to bud.I think you need a bigger carbon filter in there man. Doesn't look like it can handle that space ;)
Thank you. I had not considered the difference between root EC and tank EC, but you are of course correct.
I'm not thrilled about adding a second probe. I will try putting the probe in the discharge stream in such a way that it sees the discharge when the pump is on and sees the tank nutrients when the pump is off. Multiple plants present additional complexity, but I like the opportunity to diagnose individual plants.
I'm using a Dutch Pot type system, I can imagine simple EC probes in the bottom of each pot (pot pot??). Would it be worth $100 per plant (retail) to be able to diagnose individual plants?
I have ppm and pH pens and manually adjust ppm and pH once a day. Starting tomorrow I'll start recording return-EC as well as tank-EC. Ultimately, I want to develop an adaptive dosing system.Get yourself a ppm pen by blue lab. You don't have to leave it in the res and can move it. Not sure exactly how this system works but find a way to isolate runoff for each plant. May be a pain in the ass but worth the to study
The current design has the LED light somewhat thermally isolated at the top of the cabinet and I'm exhausting from the bottom. I cycle the fan to help control temperature.You could always put in a "dummy" or false wall in the back to hide a lot of things. Venting, piping, eletrical, etc. That's easily accessible. Would really only have to be 6" wide tops. Can have a hole out the bottom for venting.
