can someone please tell me what the temp and humidity should be in my grow tent? and if the temp drops when lights are off is that ok?:joint: thanks
 
I shoot for 75F as my target temp. You want 50+% humidity during veg and around 15-30% during flowering. There is usually a 5F swing in temps between lights off and on in my rooms.
 
For the early stage you want ~28°C and 70-80% RH.
Once the plants look healthy and firm you want 26°C and 50% RH.
You want to get to around 22°C and 20% RH by the end of flowering, changing it gradually since flipping the lights to 12\12.

If you don't have an AC and dehumidifier the OK zone is 19-32°C, >85% RH for veg and >60% RH for flowering.


You should aim for ~5°C drop at lights off.
