    Question watts v temperature

    after a search i found the Thread: Airflow / Temperature / Wattage table (and calculation).
    but, being a newbie, i didnt get much of what was being said

    not what i was looking for anyway, so a little advice please

    i'm growing 3 plants in 6ft high x 4ft square tent, 2 white widow, 1 CBD something
    the CBD has two heads now 4 1/2ft high so light is racked at top poss height, rest are 3 1/2ft- ish high
    its on 12/12 starting at 8 am
    buds came out 8 days ago, lots of nice, white heads and all looks healthy


    but, i really dont know what is more important

    if i put light at 60W, with extractor going, and tent shut, the temperature quickly hits 30 degree, if i leave it too long, while I'm at work, that can go to 34 by time i get back
    so, i open up whole front of tent to cool it off till 8pm
    i know that is bad, but they all continue to look healthy - how much does a period of excess temp hurt the THC / CBD??

    if i put light at 40W, temperature stays around 25degree with tent shut all day,


    is it more important to have the 60W light at this stage of growth
    and thus have to leave tent open all day

    or is 40W fine
    and i can leave tent zipped up all day??
