Hello once again!
I am about to switch from 18/6 to 12/12. I thought I would get a head start on my flowering stage heat and humidity control.
My research for flowering stage showed…
heat should be in range: 65F-80F
Humidity range of: 40RH-(45-50RH)
My humidity keeps spiking at night to about 80RH. I remedied by adding a heater to up the dark period heat. It was working well for the veg stage at 18/6 however I am having issues with keeping stable Temps and RH after the switch.
48"x48"x81" vivasun grow tent.
2x 1200w Greengo Led lights at 18" above plant tops.
4" ducting with vivasun charcoal filter and inline fan controlled by an bdlink temp controller.
4" ducting for intake.
Vivosun heat mat under plants (northern unheated basement gets cold) with vivasun temp controller.
700 watt radiator heater controlled by a vivasun temp controller.
Vivasun mini dehumidifier and a Everlasting Comfort humidifier both controlled by an ink bird humidity controller.
2x vivasun 6" oscillating clip fans, one above the canopy the other below.
At this point watering occurs at first light in the morning 16 fluid Oz per plant every other day.
9 plants in 3 gallon pots with soil… But will be removing 3 soon as I had a better than expected female to male development from bag seeds. Unknown strains… However all indicia or indica dominant hybrids.
In the morning my digital hydrometer shows the humidy can reach 80RH.
Thank you for taking the time to read all that!
