Office Hours Episode 103
Sensor-cleaning SOPs, grow pot materials, irrigation shot strategies, & much more!
Knowledge to help you grow smarter!
In our latest session of Office Hours, the gang was all here! Things kicked off with our Client Support Manager Rachel breaking down the best way to clean and care for your sensors. Then Jason and Seth dug into viewer questions and covered lots of topics ranging from considerations when choosing between mesh versus plastic grow pots, how to approach P1s when steering generatively, how tools like thermal cameras can support crop registration efforts, and so much more!
Some of our favorite quotes from the show:
Plastic vs Mesh Grow Pots
“With that mesh bag we get more air pruning of the roots, more splitting, more direct paths from the root tips to the plant, whereas in the plastic bag we get a little bit more root binding, a little bit more circling. So effectively you can probably grow slightly bigger plant in the mesh bag at the expense of potentially having trouble ripening later on in flower, whereas in the plastic bag we're getting a little better water-holding retention.” –Seth
Block to Slab Root-In Tips
“If you are using the AROYA system, it's really good to make sure your sensors are in the new media that you're trying to root into. And that's the one that we're watching for, to get lower in water content before we start our irrigations. And nice thing there is, as we watch the water content decrease on a daily basis, we should typically see the rate that it decreases get faster. And that's simply because we have more roots into that lower substrate and so the plant's transpiring more out of that block, more water loss due to transpiration. That's a great indicator that our rooting practice is working.” –Jason
Shots Every 15 Minutes: Why?
“Part of the big reason there is because that's a really average time around most media that we can say, hey, as long as you put on a shot that's generally under 5%, and especially if it's 3% or under, we're not going to see any channeling in between those irrigation events…We don't want to be rinsing the media while we're trying to achieve field capacity because, number one, that's not helping us achieve our EC goals necessarily, [and] number two, that's just a waste of water.” –Seth
