dim the light or higher heat..? sighs

What i would do is study the genetics of the strain your growing where its from etc ,, if rooms are hotter plant will use more water so water more and cause of more uptake back off on ferts cause you will burn them

great advice that I'm smacking myself for not doing sooner , and I grow organically with supersoil so nothing goes in but straight water and the occasional. Molasses

well i have experimented with lots of temps from mid 60's to 88 degrees C altough many its said 72 - 76 is the key area i have seen massive growth rates and yield running temps 82 - 87 degrees only thing you need to do dial in your nutrient feeding..
Meaning less nutrients as plants will take in more water,, and once you get it dialed in .. you will have faster growth then you ever seen before

This^^
if you at least have air exchange 80 degrees is manageable, just monitor the plants for signs of heat stress, if they look fine just water accordingly and lower the nutes a tad.

What the hell is wrong with 80 degrees f.? Did I miss something here? What ambient temperature are you looking for?

Thats sort of what my OP asked is 80 degrees as 100 % better or worse than 75 degrees at 75% I specifically asked that not help I need to cool it down

thanks for the reply I seriously wonder if its worty stressing about but have nothing else to go on other than forums and research being a newb still and the general consensus is always 75 during flowering and even lower the last few weeks how much does a five degree increase really make ,.... But I guess thats also strain dependant.....?

if thats the temp and you cant do anything about it just go for it 80 degrees aint rediculously hot i would have light further away and just grow those bitches 5 degrees aint alot but if its too hot the buds will end up airy you will still get smokeable bud thou prob just wont weigh as much as if the temps was ok i had serious temp probs in the past and my harvest was half of what it was when temps was ok

Oh, OK, I see what you're saying! Go with the 100% light setting. Here is my reasoning: The difference in yield between 80 degrees and 75 degrees (or so) will be slight. The difference in yield between 400 watts and 300 watts will de drastic!

copied from another thread
Sativa strains (Thai, Colombian, Hawaiian, Mexican, Jamaican) naturally grow much closer to the equator than their Indica cousins and therefore will be more resistant to heat and humidity. However, I have found that keeping temps under control will be beneficial regardless of strain. Even equatorial breeds need cool night temperatures to reach full potency and yield

actually, thinking about it I like 80 degrees for flower, you get what you call heavy feeding plants that stack on buds. Seriously I wouldn't sweat it, just water em and watch them grow

Good thread.. Lots of great advice.

Just thinking out loud because I will soon have the same issue with nowhere to vent etc.. What if you froze gallons of water and put them in a 5 gallon bucket with the lid on and drilled two 6" holes in the bucket so that air passes through the bucket and used this as your intake.?

I saw something about co2 in the earlier part of the thread.. I saw a video that stated that the co2 bags work well..

80 aint bad at all if you have a light breeze over the canopy.

Thats actually genious for veg! Idk about flowering with that humidity level though lol

Hahaha... That would be my first genius thought ever then :)

Yea, humidity would become an issue.

I am thinking of ways to cool my exhaust from my tent so I don't have to exhaust out through the most obvious window in the world..... I may try to vent into a cooler with the frozen gallons of water.. If one gallon stayed cool for 24 hours it'd be viable.

They should just make refrigerated tents or hoods :)

Take a look at you're other thread. I made just a few suggestions regarding your hid.

yeah I was thinking of doing th same just with dry ice I think it would last longer?
and I'm just going to leave it be at 100% and 80 degrees ill try to get it as low as possible th last couple weeks , airy buds were my concern everything's gone so well so far IDE hate for the buds to be super airy

One only has to look at where a plant takes up the most C02 85 - 87 degrees is the key temp :) implement them temps in your grow rooms and look out here are some pics from 2" clone not even 2 weeks vegged and some other older girls 30 days etc having decent air movement on plant canopy is key ,, and monitoring plant canopy temps ,
With increase of room temps the root system appears to work even better with gas exchange etc..
You ever walk into a green house ??? and almost stop dead at the heat , and RH ???? you notice them plants are unreal

Yeah I was gonna say, if your running at around 80 your condition isn't exactly critical at all.
Now with summer here my growroom with the lights on runs about 82. Thats a little hot but nuthin I have to do something about.
Now, if it starts pushing closer to 90, thats different.
