couple of q's

[johnny123]

hey all,can anyone tell me how important my dark cycle temps are?i am now getting down to 64f lights off 75f lights on.i had some trouble keeping temps down with lights on so i extract quite a bit which leads to my second q,do i still need to extract so much in the dark cycle.now, i have 2 rvk125's running 24/7.what i really need to know is can i stop my extraction when light is off.
i'm growing 8 ppp scrog in a 3x8x7 room, nft tank temp pretty stable at 68/70f.i'm at week 2 of flower and they look ok,so no problems yet.

so what do you guys think? :stoned:

Grow temps of between 65f and 80f is where you want to be.

thanks tt, so am i ok to stop fans at lights off ?

[tinytoon]

you said you have 2 fans running so shut 1 down and see how temps react and you should have your answer :jointsmile:

[johnny123]

sorry about takeing so long to reply, some shit happened here.
anyway ,yeh sorry tt i should have said one fan pulls through an air cooled super nova 6" from outside the room so shouldn't make any differance. unless it gets so cold lights off that it acts like a chiller.the other one pulls through a carbon filter and out so if i turn it off i have almost a sealed room (sealed if i close intake vents) my main concern is can my plants handle no air exchange in the dark hours?hmmmm i hope so cos i just turned them off.
if anybody thinks this is going to harm my plants please let me know ASAP.
so to recap on temps 24c-75f lights on 18c-64f lights off.
or am i just flapping and there is no problem?:wtf:

75f and 64f are fine .... no temp probs there. I guessing the fan for the light is off when light off yes? I run 2 seperate cabs in same room. both have exhaust fans that are on 24/7, I run cooltubes which fans run only with light and lastly both cabs have small desktop fans for circulation. I will be installing an exhaust blower that will be venting the room as this summer will give me heat probs if I dont.

hi again,normally i run both fans 24/7 simply because i havent got around to buying another timer.i was thinking if its not a problem dont make it one.also they only use minimal electricity.i also have a 16" oscillating fan blowing between light and tops when light on and 15 mins each hour light off.may sound like overkill but i've had heat probs in the past and their a bitch.
well its good to hear confirmation on temps.
i've just changed to the full canna aqua line plus gt liquid silicone and everything is spot on (finally 2years after starting growing my own) i just want to make sure it stays that way lol.
