Except you would be recycling warm water.
93 degrees, too hot?

From my reading, 87 is the ideal temp. 90+ is supposed to be bad, but like someone else said, that's dependent on the strain.

76 is the ideal temp not 87!!

Air density is very important if you want to grow in high tempatures. Put a small intake fan at the base of your closet and have an exhaust port(s) without a fan in the upper region. This will increase the atmospheric pressure and make the air thicker in hotter temps. Your plants will love you for it.

any grow temp above 80 will cause your plants to close down, leaving your tips on your leaves to bend upwards, not allowing them to photosynthesis. i find the perfect temp is between 70 to 78. i would surgest doing some homework on the strains you grow. Some strains like Himalayan gold like it really cold, others a little hotter. When my rooms have got to hot in the past i have found that there was not enough air flow in my room, fitting more intake fans helped greatly, dont make my mistake i pointed a fan in the direction of my plants and 1 of them ended up with bud rot.
the best piece of advice i can give is always do your homework, buy a growers book like the growers bible ( jordge crevates) it will pay for itself in 1 grow, without books like these i would still be asking questions too.
Hope this helps you and happy growing

That is totally incorrect. My grow temps never get below 84 and like I have said a hundred times on here It is well over 100 degrees all day where most of these strains originated. My tent goes as high as 93 in the summer and I still do not know what heat stress looks like. I grow 3-8 strains at all times and my last grow flowered at 85-87 and I got 318 grams off a 2x3 screen with a T5 so by what everybody is saying I could have doubled that if my tent was 7 degrees cooler? Come on people. Lets recap shall we 2x3 screen, 6 T5 bulbs 87 degree temps and Jack's Classic nutes = .98 grams per watt. Any questions?

totally incorrect? why do you think you know more than growers who for years have done this for a living in places like amsterdam who grow millions of £`s worth over there life time. to be honest if your using a little t5 how do your temps gets so hi? i use 600w sunmasters and my temps never ever get anywere near these, if they did i would be well worried. my last grow was in an nft systerm using ec & ph meters over a hps 600, just of 1 girl i pulled 360g, another 255g never mind the rest of them. each to there own some people just dont listen so why bother?

Wheres the journal? I think I know more than all those huge growers because I have been doing it and getting results with no stress. I dont ask a question here and take the first answer I wanna hear. I dont pay attention to the trends. I dont buy into the propaganda. I do what all those commercial growers do. I grow weed until I figure out what works. The bottom line is product and I am getting the oh holy 1 per watt with my $400 setup and my high temps. Ps T5's make heat too pal.

When a deep sea divers comes up from the depth they have to stay in a decompression chamber because the compressed nitrogen will disipitate without compression and become bubbles in his blood. The same thing happens with nitrogen when you lower the atmospheric pressure in the room with an exhaust fan without an equal or greater intake fan. The excess heat also thins the air and contributes to this rapid nitrogen desipitation. In positive air pressure nitrogen will desipitate more slower. Negetive air pressure causes rapid desipitation of nitrogen and causes what everyone here beleives is heat stress. Make sure you keep equal or positive air pressure in your op so your fertilizer can react properly. I'm really buzzed so I hope I wrote that correctly.

Also which region is consistantly that much higher in temp? 120 all day? Ethiopia clocks in at 94 degree F highest mean temp. Even death valley has a mean temp of 92degree from june-august.... so what planet you growing on? Another thing to consider is those HIGH heat regions are LOW humidity arid places where the plant can cool itself very easily(transpire). Try a 85 degree day in a georgia swamp versus a 95 degree day in colorado.... I'd prefer the dry colorado air to the swamp any day.

So many people say that'll be too hot but I'm growing 5 NL plants and the temps are above 90 when my door is closed any I've had zero problems so I'd say you'll be alright man.

Same here, my temps have ranged from 75 to 90 over the passed few weeks, no concern here either
