heat can stress the hell outta plants and also completely stunt there growth. get them conditions right or it will be a big waste. trust me. i been there. get an air conditioning unit in there. also make sure everything is vented properly. check out venting 101. that may help
Hey There.
Hey There.
YES! Growth pretty much stops at 30c. You will need an extractor fan,
Ideal temp is 24c or thereabouts. Obtain a hygrometre too, if you can.
good luck trakulis.

where do you guys get this info from?
36c is what? over 100 degrees? i would try and bring it down to no more than 92 degrees or so. anything over that and the plants are really stretchy and stressed, slow to flower, loose fluffy buds etc. ive grown plants in constant 90+ degree temps with highs in the 100's on hot days outside. the growth didnt stop but the flowers came on slow. plus theres a lot of stress from being in a hotbox like that for plants.
75-90 degrees or so is a fine range to grow in. try and get it to mid 80's if possible.
this is 89 degrees as you can see, which is like 32c or something. plants are growing just fine.
this is the last picture i took before i had to chop this grow early. as you can see constant temps over 30c did not STOP GROWTH.
86degrees is an ideal temperature. i dont mean to cast doubt on jorge, but i think you should go reread where you saw that at. its routinely constantly 90+degrees all the time in some places on earth and weed grows just about everywhere. in florida for instance its close to 90degrees everyday of the year just about. in mexico, texas places like that its 100+ degrees a lot of the time. lots of weed coming from those places. cali for instance. hot place. lots of weed.

I dont like to compare indoor grows to outdoor grows,but 85 degrees is just fine to veg plants in.Personally I like the slightly higher temps in conjunction with a cool mist humidifier because of one word,spidermites.Although your plants look OK bro I still wouldnt want to flower at 30C without co2 enrichment.1500PPM and 30C is my flowering recipe

My lights on temps have been in the mid 90's -105 f for the entire grow before. I still got decent results. It is easy to over fert at such a high temp. Normally I feed every other watering but that is too much for high heat because they need watered more often. 75-85 is ideal but that doesn't mean that temps have to be in that range to get good results.

Ok. I think we're both half right
, in jorge's bible it says " Daytime temps above 29c (85f) will SLOW growth" , (my emphasis),
He recommends 22-24c (72-76f) as the ideal temp.
Soma says 22-27c (72-81f) is what he tries to keep his room at.
Ed Rosenthal prefers 70-74f (from Ask Ed),
But what works, works. If you're getting good bud whats a few degrees between friends.
Have a good one

heat will stopp growth
heat will stopp growth
Im not tryin to dog anyone here but I personally had easy bake oven issues with my one run when the temps were in the mid 90,s. n oh yeah. plants stop growing at 83 degrees. Ive been doin this for awhile and learned more through trial an error than internet reading. kif if you want some good nugs and yeild get them temps dialed to 78 degrees day and 68 at nite. if people here think im wrong. well then. have fun dealing with thriving mites, stressed plants, ect. ive been there and it doesnt work indoors like it does outdoors. so either take note of my info and the problems i already had. well hell here is a pic. this is week 8 of flower. and yeah it dont look it. cause they got stressed from 90 degree heat. If yall are gettin 1 gram per watt in these conditions i want pics and proof. cause it wont ever happen. i already been there. I deal conditions is what you need to get the best results out of your girls

i usually get my info from experience and other experienced growers. I usually never turn to the internet because here everyone thinks there right. And stihgnobevoli, those girls are small as shit. growth was stunted on them and i can see it from the plant on the left and right. you dont even have an 1/8th off of 2 plants and your going to tell me your growth wasnt stunted. Ive put clones in straight outta the box and yeilded up to an oz easily in right conditions. so yeah if you guys wanna lose a lb or so of yeild. then go ahead and grow in a hotbox. o and hot weathered climates like cali and mexico. remember its cooler at nite. n most of the weed in mexico is dirt if ya havent noticed. field weed. not tons of yeild and very little thc. due to crappy conditions. it aint about readin . its about experience and doing. Have ya ever been to mexico and seen any fields there or how the mj grows there in those climates. compared to ho much different our dense sticky frosty indoor nugs are. come on people. thought this place was to be a HELP. so far I see a bunch of know it alls that just get there info from reading and not doing. fuckin typical.
Hi there,
I also get my info from experiece, most people, however, require solid quotes from famous growers to accept ones advice. I'm averageing 23g per under 3cfl's and frankly i'm too high to get upset about mistakes not happening in my growroom. I know I don't know it all so i hit the books to verify my first point which was that growth stops at 30c,
And your point about mexican outdoor was well made.
peace

I'd be more concerned about odor control and circulation, properly vented it will take care of all three.
Do what you have to to get your temps below 30'C. Everybody agree? And good ventilation of coarse.
HEAR HEAR!

those girls were grown from clone for roughly 7 weeks before i chopped them. i had to chop em 3 weeks early cuz i was moving. they were smaller than what i would have liked but thats cuz they were way early. this picture is just the biggest cola from one of the plants. in the picture i posted it was 3 clones of the same mother i call sasha. the 2 bigger ones i was growing with GH lucas formula, and the small one you say is stunted from heat i grew using alaska for comparison.
i dont know who these know it alls you are referring to are, but i assume maybe yourself. everything i speak of is from experience. lots of trial and error. im not asking you to take it as gospel but i am speaking from experience and it would be wise to at least consider my advice.
and fyi i got 1 whole ounce off of the 2 plants on the right. the one on the left i gave to a friend. i think an ounce from 2 small plants which are barely a whole foot from the soil to the top of the cola is a good haul.

just few days ago i started a new grow temps were maxin out at 96F/36C just like yours i went to a lil dollar store picked up a cheapo 10 dollar fan plugged her in and checked the max temps the next night and i was shocked and amazed; max after the fan was 86F/30C. Im not gonna debate the perfect temps to have cause honestly Im not sure but I am sure that a 10 degree or 6 for you celcius folk from a 10 $ fan is great.
really i thought the fan may save me 3 -5 degrees damn thing put me right in the range i was shootin for and it cant be bigger then maybe 8 inches, but has seemed to work wonders for my temps.
Hope that gives ya an idea to try hell it cant hurt anything
