The gang was all here for Episode 123! And over the course of a packed hour we got deep into the weeds of everything from the challenges of figuring out optimal sensor placement (and more) with larger sizes pots, learning from a high runoff EC, temporary versus permanent wilting point, and lots more!
We’re on hiatus next week for the Thanksgiving holiday, then we’ll be hitting the road for MJBizCon – we hope to see you in Las Vegas!
"When I'm in a larger media like that, I'm going to see some pretty substantial VWC and EC gradients. And so insertion from the outside isn't necessarily going to give us the most representative number…I would try and place it within a quadrant in that 15-gallon pot. So if you think about, all right, let's be halfway between the center of the pot and the outside of the pot, bury that sensor in typically, you know, a quarter of the way up and then a quarter of the way in. So if we set the diameter of that pot is, you know, 20 inches, then you know, we would want to be at 5 inches in and if it's 20 inches high, then we'd want to be at 5 inches up.” – Jason
“We really want to see what that reading is in the zone where the roots are actually uptaking water and being active so that we know we're not over watering that huge pot. When you dry that pot down, we do want oxygen to come all the way down deep into the pot. And if you're not getting a dry back at the appropriate level, then we're not going to see the best plant health.” – Seth
“I love picking up the pots…One of the nice things is that modern tech doesn't prevent you from doing that. I still go in there all the time and pick up the pots just to make sure that I am correlating those values that I'm seeing on my graphs to that same methodology we all learned on, you know, how heavy is this? And does it feel like it needs water?” – Cian
