yes i know, but i have my grow box in the attic where it gets way to hot up there. i also had a 1000w system / with a cool tube. was using over 7000 kilawatts a month , along with my other household items, went down to a 400w system and in the winter time i was 6000 kilawatts a month. so it is time to take another downsize to get these kilawatts down.
