Friday: Today I am pulling the tent apart to re-run all of the wires from the AC Infinity Controller. I’m also adding a new grow tent heater. My goal is to set up a humidifier and heater to maintain a 1.0 VPD in the tent. More photos to follow this week since I update my journal daily. Checked the ppm in the reservoirs and it’s at 1,000. Added more RO water with extra nitrogen to bring the ppm level down to 925. Saturday: I installed an updated AC Infinity controller 69 Pro Plus (controls 8 functions) which allowed me to add a humidifier and heater to the controller. Overall I’m extremely impressed with this AC Infinity equipment. My VPD is within the range I want to achieve (.8-1.1). I programmed it to maintain 78 degrees and 67% humidity during the day, 73 degrees and 63% humidity at night. Charts posted also show the impact of an open tent compared to the closed environment. The heater is constantly pushing fresh air into the tent, so I don’t need to cycle the exhaust fan often.
