I wouldn’t place the sensor “in” the plant. The pulse is billed as “The smart environmental monitor” and, in that role, it reports the conditions in the growing environment.
My Pulse is in a little 2’ x 4’ tent and, since my grow is now in seedling/early veg, the Pulse is sitting on top of the reservoir, right next to the plants. When the plants get bigger, I hang it off of a cross bar at the back of the tent and keep it at about canopy height.
In your setup, I’d raise it to canopy height and move it off to the side, per [the docs].(Where do I place my Pulse? | Pulse Labs Help Center) Well, the doc, I should say.
I’d be really tempted to hang it in the center of the grow and perhaps Pete could weigh in on that very question. My thinking is that if you’re using LED"s there’s very little IR vs HPS/CMH/etc. so it might be OK to move the Pulse to the center. Dunno. I’ve tried it in both locations over the past year and found no significant difference so I just keep it in the back, out of the way.
Great looking set up, BTW.
