temp question

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? 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.
