OPEN THE DOOR TO YOUR GROW SPACE NOW! You'll have to leave it open until you can buy an exhaust system. If you can't afford one you're going to have to leave the door open, period. Can you take pic's? Also if you have the cash buy some Co2 from the shop, if not there are some excellent posts on this site on how to make your own. Co2 enriched air enables the plants to handle much higher temp's. I read in Soft Secrets that they can take temps up to the mid 90's if the Co2 concentration is right. Soft Secrets is a newspaper for growers printed in Holland.
