So I’m running a Gorilla Grow 5’ X 9’ tent with 2 X KIND LED X2 Commercial LED fixtures with a 14,000 BTU portable dual hose AC to keep the CO2 in the tent & a dehumidifier & 2 identical humidifiers. My daytime VDP is oscillating by 22%, that’s a bit much… I was really hoping to get it dialed in as close to optimum as possible to increase yield. I’m using Inkbirds to control the temperature & humidity in the tent, the temperature Inkbird feeds the trigger coil of an external relay box I built so the Inkbird didn’t have to try to power the 14k BTU. The VDP oscillates ~20-22% from 1.4 kPa - 0.7 kPa, if anyone has any ideas please let me know!
Here’s a link to view an hour of my day cycle:
I’m quite surprised I don’t really see this same question asked anywhere else, I can’t be the only person having this problem…
By the way, to the people at Pulse, I absolutely love this device! If I could make any changes, maybe a rubber case to protect it, $500 is quite a bit to drop & worry about dropping it. Also, it’d be an awesome addition if I the graph was able to plot a horizontal line for my VDP goal setting & maybe additionally a horizontal line for my VDP high & low limits & those select switches to turn these lines on & off. Perhaps the ability to plot the same lines for Temperature or humidity or whatever variable someone is trying to work out, it just seems like it’d be quite handy to me. Otherwise, it’s an amazing device, I love being able to see my lights spectrum.
