Plus you can cool more tents of one small air con by doing it this way.... The more tents u need to cool make the box bigger

And the air con wont be working flat out this way so its cheaper on elec and longer life on the ac

Yeah if i build rooms inside the shed ill be going ducted ac

I like the tents tho cause can easily be removed if needed ya know

lol humidity isnt relative to heat at all. where i am it can be 20c and still be 85% but air cons do dry out the air, thats why when u stick the aircon on in your car it de mists the windscreen so quick.

actually humidity is extremely relevant to heat, i done alot of research here, and meaning, the more heat you have, the more humidity, as you will have more transpiration from the leaves. just because you can have 85% humidity with low heat, just indicates a confined space, with not enough circulation of fresh air.
trust me , i done extensive research on this, and humidity will only play a vital role in hight temperature rooms when lights go out and there's not enough circulation to evaporate the transpiration process, thus creating an extreme high humidity environment. u need to get fresh air in, even if it's from an evap cooler. the amount of water evaporation is fairly minimal with a evap cooler, aslong as you keep the ice up, and the cooler out of the tent in the ambient air. not in the tent.
an ac will dry the air out because its simply dry air, and u are pushing the dense 'wet' air out. but an ac will kill co2 levels, so you have to include fresh air from somewhere.
hope this helps.
i noticed with my last grow my humidity levels were fine with light on, but when light when out, humidity climbed. but adding fresh air helps, as humid air is more dense and the extraction is difficult to empty a room that is high humidity if you have no fresh air

Sorry wrote it wrong not relative to heat ... ment relitive humidity... EXplained as follows as the are different ways of decribing humidity.. it is so called because it measures the current absolute humidity relative to the maximum. Specific humidity is a ratio of the water vapor content of the mixture to the total air content (on a mass basis). The water vapor content of the mixture can be measured either as mass per volume or as a partial pressure, depending on the usage.of course the drier the air the lower the humidity.... My point was the higher the temp in ya tent will be drawing moisture out of the mediium hence higher humidity

Exaclty right circulation is the key .. Grade 8 science ... ive never had a prob with co2 levels being killed using ac... Higher the humidity affects co2 levels as it binds with the water vapour in the air.. Obviously if you have dry hot air it affects co 2 aswell so at 60percent humidity with 24 degrees celcius ac you wont get any probs with co2 being killed.. If it was that easy to kill co2 we wouldnt have a debate about carbon tax.... Plants turn co 2 into oxygen.. We are getting too much co2 plus other carbons in the atmosphere .... Due to clearing and pollution. but too low of a temp will affect co2 aswell .. a balance is always right...

i agree, i think as long as you keep the air moving around, that extra humidity created from the heat can be extracted and fresh air will replace it. i had to think about this alot and talk to a couple of long time growers. some people may never have this problem simply cause there setup is just plain different. one guy i spoke to actually spoke of his leaves actually used to drip!! and his roof of his tent and walls were actually wet!! OMG i was shocked, he said it's due to extraction levels not being high enough, as soon as this person got a new extraction fan. bang. problem gone.
humidity is a bugger, because if you can get it perfect it will help greatly but if you have it that much too high, and you get buds getting dripped on! man, i could only imagine how this could make mould, especially with lights out
freaky shit

co2 in lower temps is afected by what is called the dew point

you would notice co2 levels drop if there was a meter involved and you didnt have enough fresh air, co2 would drop with an ac, sounds like you got plenty of fresh air, window open perhaps? i do

Hell yeah man its one of those things thats purely scientific . You need to calcutate all the variables to keep it under controll

No i run in tents with purely on filtered ac.. the box i have the ac in does get a bit of fresh air in due to the need to feed the ac with air so its possible it could be mixing with the cold air the ac is pumping into the box... I run infra red co2 censors

also depends how much and how often ya pump in co2 to as to whether the ac affects it aswell
Supa smoka
Well-Known Member
Um i mean as to how much the ac affects it depends on what amount of co2 ya pump in and how often...

easier to open a window 
suck the heat out and blow it out of the room with a big mother fan, thats wat i do

All the circulation in the world wont help me where I live. 80% humidity is the norm outside so I will just be recirculating 80%. I really need a dehumidi or an aircon to actually drop the natural humidity
