hard to find a direct answer on the web I know photosynthesis stops over 105 but using my 400mh my tent gets to about 85 ambient when its closed.. its not that high but would it truly affect my grow or yield. its the heat of the summer so it can only go down from here but I would like to get someones 2 cents in. my res is perfect I am using a 48quart icechest and with 1-2 frozen bottles a day it never goes over 66 but i don't have an ir thermometer yet to check the plant and don't wanna stunt anything

it can go down to 60 at night , or in low temps. 85 is pretty okay just make sure youre ventilated
should be between 70-80 but everyones answers generally differ by 5 or so

i never said you had to spend 300$ on an ac unit. a fan works..think they are like 10$

85 is border line if it gets higher it will affect growth rate and yield. unless you add co2. try a 6 inch duct fan outside the tent keeping it on the floor run ducting into the tent cool air into the tent. vent fan high in tent pulling hot air out.
