yeah worry about creating a good environment for your plants b4 you even germinate. i think people should set up their rooms and let them run for a couple days to make sure everything is spot on. cause if your growing in constantly fluxing temps from high to low and vice versa your probably ganna come out with most males and hermies. your on the right track bryant but just keep on workin at it. like you said trial and error. and a whole lotta reading. ur def ganna have to a/c ur grow room. my grow room is in a bedroom and i thought i might of had to get a 5,000 btu a/c to fix the heat but its settled now that i have my lights vented. oh yeah def ganna have to vent your lights. an attic is hot enough as it is. and with the space your using your ganna need AT LEAST 2 1000 watters, thats some heat right there boy.
