a/c unit

so ill post that here maybe its better.i have a closet grow inside a room.my temp was at about 30c inside the closet cos its fuckin hot here.so i run my a/c unit (10000 btu) in the room.my closet temp then was 27-28.i left an inside door opened for some air change but in the morning when i woke up the plants were somekind droopy the leaves were curling under.so is this cos of the air was not coming from outside?also my a/c is ventin outside the house.so??

Fresh air is VERY VERY important. Lack of it will cause problems. Having said that, the drooping could have been caused by a few different things. Lack of fresh air is one of them. It could also be over or underwatering, or low humidity from the A/C? All you can do is know what conditions are best, and do your best to provide them. Good luck!

ok my humidity was 45. i dont think is possible to grow inhere with 40c during the summer.mediteranean is fuckin hot.ill change air more.the plants were well watered not over.so i guess was the air.
