i have read that i should have a temp drop of 10-20 degrees when the lights go off. but have seen people on ther sites saying keep the lights on and lights off temps as close as possible any ideas anyone?
As long as your temperatures are 75-80 degrees you will be fine. A good lights off temp is 65-70. You don't HAVE to have them at a certain temperature lights off, just don't have any extremes.
Temps usually drop at night, if you think it's too cold maybe change your light schedule so they're off during the day and on at night. But usually when the temps drop at night it isnt a big issue.
then you shopuld have just wrote that... 75-80 colder if you want purple in the buds. but it stress's the plant..
i dont wanna stress the plants i have it at 80f during lights on and 73f with lights off with a defferential of about 2-3 degrees should i just keep it the same during lights on and lights off? i dont know what you mean 75-80 colder?
I would keep the room at 75 through out the whoooole grow.. do what you need to, to keep it at that temp.. lights off/and on try and keep it 75... if you want purple stuff keep it colder .. but that stress's the plant out.. it was just an extra tip..thats all.. so 75 is where it should be at.. i have an AC that i use.. i have 800 watt HPS so i keep my AC thermostat at 70-72, in conjuction with my HID's it keeps my room at about 76-77.. i have pics of it on my journal.. hope that helped clear it up..good luck
I range from 82F with lights on and 77-79F with them off, humidity between 43-55% as well. My plants have responded quite well. From my experience, you'll be fine.
