yes that is a bit hot unless you have added CO2
at 90 most strains will shut down (stop growing, not die)
this is not true of all strains as sativa dom plants can take more heat
if you are in veg it will most likely be ok but too high for flowering

yeah i have three fans. one blowin out of the closet on blowin in. one circulating. i am using green pads for co2. they are these fabric sheet things you mist and the humidity makes it give off co2. i have two up. u think this will be good for flowering. i mean pot grows in hawaii in 95 degree temp right

im gonna give you a few tips seeing as i dealt with the same problems during the start of my closet grow. My temp was usually around 85-90 and i was constantly worried about how it would affect my plants. while your plant can grow in temps above 80-85-90 ... its not ideal. when i say ideal i mean if your trying to get the most out of what your growing ( yield, speed of growth ) then your going to want temps in the mid to high 70's. ideally between 75-79 degrees. variables like humidity, light, and heat play major roles in the health and yield of your plant.
it all comes down to the question " how well do you want to grow your bud "
variables like the ones above seperate the good bud from the GREAT bud.
first thing i found out is that if you dont have an air cooled hood , a fan can actually be counterproductive to trying to cool your room down. unless its blowing on your plant cooling it down, all it is doing is blowing around hot air. i noticed that with the fan off and my intake & exhaust, temps dropped about 5-6 degrees.
Second thing ive found out is if you have an hps light you CAN NOT get around good circulation. im not talking about fans, im talking about an intake and an exhaust. even if you simply have an inline fan, it should still create some kind of a passive intake by itself ( it creates a vaccum in the room and sucks air from the next room or closest opening that it can draw air from ) .
with this in check, and a good ambient temp being drawn in from the intake, you can as effectively as possible exhaust the rising hot air and replace it with the cooler air from the room over.
Third thing ive found out is just theres no substitute for doing it right. I realize most people dont have big budgets when they are starting out with growing. its a hobby or a job which can exhaust funds like no other. but money aside , its good to do things right so you can get the most out of the hard work you put into your operation.
if the high temp persists, come to term with the facts that it may be in your and the plants best interest to think about investing in better exhaust or a portable a/c ( check on craigs list for these, i got mine for 50 dollars! ) . good luck !

There is a difference between:
ambient temps - The Temperature of the air in your room - what most thermometers pick up
plant matter temp- The temperature of your plant. - An infrared thermometer is a great way to see what your actual temps on the plants are. Even in 88 degrees your plant matter at canaopy level can be 80-82 degrees. Your plant is constantly evaporating water and cooling itself.
Just some food for thought before you go crazy trying to cool your plants. - fans are your friends, the plants will help cool themselves.

It is rather interesting that outdoor grows can survive just fine in temps of 90/100+
for days on end. Wonder why indoor plants are so heat sensitive? Just a thought.....Good luck & good grow.....BB

My indoor plants have seen temps up to 105F and survive just fine, it does not kill em it simply slows thier growth at temps over 90 MJ shuts down and new growth slows to a halt, so stresses and stunts them, same happens outdoors unless it is 100% sativa strain which can handle higher temps

I got lucky and discovered that my stealth closet was right next to an unused chimney. I simply removed one of the bricks, and installed a ventillation duct. My stealth grows constantly have moving air and my temps rarely get above 85. It's awesome.
temperature limit is also realative to humidity. What i mean is if you have a higher humidity garden, you won't be able to sustain as high a temperature in the garden as if it is arid. So don't forget to account for your relative humidity as well. As a rule though, I would say that you don't ever want to let your temp get above 86 degrees ever but I try to keep my temp between 76 degrees and 81 degrees with 45% humidity. (This is for flowering).

wwll i cut a hole in the top of my closet door with a fan inside blowing hott air out. i also cut a whole in the bottome of the door with a fan blowing in for some fresh air. so far my temps havent gone above 85f this way. its usually starying around 82f-83f. so for now this is working. i have pics onmy pro. so thanx for all your help guys. this should do it until the really hot days in the summer come. and then i should have my ac bought and in by then

if you have plenty of fresh air flow and a great exhaust then the high temps will not hurt. just during flower keep your humidity down in the 20's to 30's.. i have flowered with temps as high as 102 degress fahrenheit with the biggest yield i have ever yielded off one plant.. 412 dry grams.

thanx buddy. i have made an exhaust and intake hole in my door to my closet. i have the exhausr=t at the top of the door with a fan on a shelf in the closet blowing directly out the hole. my intake hole is in the bottom of the door wiht a fan attached to it blowing cool air in. i also have a fan inside my closet rotating the air and circulating it. i put the exhast hole at the top because hot air rises and the fan will blow the hot air out.
