Hi all. I have started my first legal recreational grow using LEDs. You can check out my journal here: First Legal Recreational Grow - Canada Eh!?
So I have been running some temp/humidity tests over the past few days while my seeds are sprouting. I want to get a sense of what variances my plants might experience.
Currently I have a 240W QB288 3500k with Cree 660nm deep red. Bought this from KingBrite. When I have the LED on my temps are getting to about 34C and Humidity of 35%. With lights off I am getting about 19C and 55% humidity. I am running my exhaust fan with light off at very low speed today which seems to control humidity well, prior to this I had everything inside the tent turned off and humidity spiked to 83% and temp of 17.5C. A tricky science.
My question to you experts is this. Based on my setup(check journal) do you think adding an intake fan at the bottom to pull air from outside in will help temps?
Also, where is the best placement for my hygrometer. I’ve moved it around to see what my temp and humidity is at and wherever I move it I get different readings, significant differences. Above the LED verses below LED, sitting next to plant base? Mounted to wall of tent? I have tried all this positions and can’t seem to get a consistent reading to be able to say, this is the temp and humidity of my tent.
Any help is appreciated.
