in my room its 75 in dark and just under 80 at night there 3 weeks away from harvest ive got extractor on all the time and two oscillating fans

will they be otay?
 
u think ill be ok for another 3 week wats signs of heat stress coz i cant tell by browning hairs coz most of them are brown ? what temp should i be worried at 80? night
 
If you mean 80 with lights on and fans running then 'fine, no problem at all :-) These plants will take some serious abuse and those temps are really not too bad at all. Try not to worry about plants 'turning hermi', that is such a rare occurrence and is mostly genetic or as a result of EXTREME stress. This is another of those canna myths. In the past 12 years of constant grows I have seen no more than 4 true genetic hermi plants, so this gives you some perspective. There are those who will tell you that if you so much as breathe on a plant or fart near it, it will 'stress' it :-)

Those temps wont cause heat stress, they need to be much higher and the signs are obvious, severe 'cupping' of the leaf and shrivelling. You need to be very close to the lights to do that.

Hope this reassures you.

Nicely put.. if you don't mind.. may I add something? As long as you keep your 'lights on tempatures' below 90`F.. usually your plants will be just fine.. anything above this.. and you'll start stressing the plant.. and the leafs will start to 'cup' and get crispy.. eventually falling off the plant.. which you don't want.

just thought I'd add that bit of information.
 
wen lights are on its fine because its really hot here at this point in time i knew this was coming thats why they are no light in day and light on at night so temps in day are around 78 to 75 now but they was around 65 few days ago but at night it gets really cold so the light makes the temp bak up to 78 again but this isnt my first grow thats how i no about hermis all 6 of mine turned because of heat stress but im just scared coz the day its the same as night with light on ?
 
plus i check them today no signs of heat stress thank god :D still scared :( i trimed all big fan leaves away to make air flow better was this a good idea or bad idea
 
its the humidity you want to watch. the lower the better. try to keep it 30% or lower... this helps with densing up the buds, and lower the risk of molds and meldews..
 
i swear your question has been answere a few times already. But your fine. those are good temps and from what i hear you should not have cut the fan leaves off. Thos act as solar panels for the plant meaning that is where they get most of their energy from.
 
ah shit :P i left all the bud leaves in my defence :P i had a idea if i cut leaves it makes air flow better witch would cool the plants o dear :(
