@neofraud_811 looking good ,how is your temp and humidity. Here is some good reading

Vpd help please!

I’m confused about vpd(vapor pressure deficit). It seems to be there are conflicting opinions out there. Attached I have two recommended charts for vpd. One is more general and states for a temp of 77 Fahrenheit/25 Celsius the ideal humidity is 70%-75%. On the other chart it states for plants in mid flower the ideal humidity for the same temperature is 45%-55%. That’s a huge difference! What is right?? Thank you. [image] [image]
