I am so excited I have to share this.
I thought I was good before. But I think I am taking the next step to becoming great. I hope some of you can give me some constructive criticism.
I just spent the weekend wrapping my head around Vapour Pressure Deficit and plant biology in general. I can't believe something as important as VPD wasn't at the forefront of my mind before. I'm thinking I was intimidated by the concept a few years ago when I set up my tent because I don't even remember stumbling across the term.
I blast the light in my 4x4 tent (2x 315watt CMH). I needed heavy cooling. I opted to take in fresh air from directly outside in the pacific northwest with about 500CFM. I wrote off ever being able to control humidity because of that (What's the point of a dehumidifier when you are exchanging the air so quickly right?). And it is humid here in the winter. Even still...I grew a few good harvests. REMO nutrients are great. Good genetics was even better for sure. Help from Pennywise and InTheShed was invaluable.
However, after discovering VPD charts, I realized that all too often...I am NOT in that sweet zone. And in order to hit that sweet spot of transpiration, I don't need to change the humidity, I can change the temperature!!!
Boom. Fast forward to me now waiting for my WIFI thermostat that I can REMOTELY change the setpoint temperature of my tent!!!
My plan is to have a 200CFM exhaust fan run at all times, and use the 500CFM fan for heat removal when the setpoint is overcome. I'm not too worried about heating the space as it's rarely too cold. Although I may discover different now that I have the ability to monitor temps at night from my cell-phone. I could easily add a heater to the passive intake wired to the thermostat.
Then I will monitor the government website for the humidity in my neighbourhood, and then remotely change the setpoint of my tent as per the VPD chart to get where I want to be.
WHOOO HOOOO!!!! WHO USES REMOTE THERMOSTATS?????
Game changer or no???
