Temp Ques

I have a 400wMH in my closet, I have it vented as best as possible.

What is the warmest it can be and still get good growth?
I'm veging, in my 4'th week, running lights 18/6

85 is pretty much tops.

no your not suppose to let them get to 85 thats when the go into survive mode and not grow. should be aiming for 75 but slightly warmer do help it grow a little faster. happy harvest

His question was. "How hot can i have it my grow room before doing harm?
85 is as hot as ya want to go. That is not ideal thats max temp.

@ 85* the plant vents using valuable energy it needs for flowering 76* is prime

dirty your a rook. go read up on your stuff before you try to give people advice rookness

my home is 2x4 7ft tall 5 15watt cfl 900 lumens 3 23 watts 1400lummens and 2 30 watts 2060 lumens my room is always above 85 avg. 90+ to 100 one day it was 105 and those fuckers grow the fuck up my humidity never is never higher then 30 and there only bout 3 weeks from seeds and look damn nice acually but i need to get the temp down prolly end up putting a ac type thing on there.... but its always warm in the room with low ass humidity (which will be nice for budding) but im worried one day its going to fuck it up some how if it stays to hot

you need to get that temp down in your grow room and if you could put some pix so could give you some advice on how to lower the temp.

ill try to post em right now but last time it didnt work but give me a min there nice pics im takin em right now

i got a nice size fan in top of room blowing down that really helps plus i switched around lights from the shroud(30watts to 15 watts) that helped too

theres nicer ones but didnt feel like getting to em right now but there all nice dark green

first off you need a fan thats close to the grown cuz heat rises have the fan blowing on your plants perferably a fan the swings from side to side you need air to circulate. and are you growing in a closet?

ya its a 6 ft long closet and i put a piece of plywood up 2ft from the back of wall and put up a shelf and you cant even tell its there its a secret bad ass little deal but i got bad ventalation and i leave the door cracked open got the air circulation and to let the heat out....i dont want to put and noticable holes in the wall for venting but im going to have to i think..putting the fan higher acually helped a bit and switchin lights around temp avg in 90s upper instead of 100s for now but there not fucked up so im not to worried bout it

is your closet single door or sliding?

i do have a small purifier i took the screen out for more flow and its blowing out the cracked door

its bout 1ft and 8inches or less and opens towards me 4ft tall door

Well, my question has been answered 85F by many.

But ismokalotaganja has shown pics of otherwise.
Still would like to see more input from others.
Thanks though ismokalotaganja you have at least made me feel better for the moment.

so its a single not a slider right

yup single door

could you leave the door open while you have the light on? and make sure that the fan blowing the air out is higher the the on bringing in fresh air in
