Hello everyone hope you’re all well and having fun gardening. So I keep getting mixed signals about humidity control. Some people say 40 to 60 range other people say 50 to 70 range. Me living in a rainy state I’ve got to try to find that sweet spot. Once I find it I want to try to stay there. LOL. So my question is what does everybody else think the proper humidity during flower should be? Thank you in advance for everybody’s opinion.
Relative Humidity (rH) should be determined by the which growth stage the plant is in and by your temperature (thus relative humidity). The Vapor Pressure Deficit chart (VPD) is how I determine where to set my temperature and humidity levels.
Here is just one version of the chart:
And here is another:
Great. Thank you very much for the chart
Merlin has got you covered
Last week before harvest drop humidty to like 30% this will boost terp production according to the claims.
Thank you for the tip I appreciate it
