I'm guessing that the fans are exhausting out of room. Only thing I might be able to suggest would be either intake air coming from outside and venting to outside as well or (what I am stuck doing) get yourself a portable ac unit.
BTW I would go with the ST right from the get go, does real good job helping plants get started and such.
tinytoon Reviewed by tinytoon on . getting started Well hello all I was hoping to get some answers for few questions. I am about to start my first grow room and i just want to make sure im starting out right. My room is 7ft long by 4.5ft wide by 6.5 tall, i plan to run two 4 foot flourescents until sprouts emerge and then for another week or so and transfer to hydroton in a rubbermaid set up. Do I need to soak my hydroton in ph balnced water before i use it and if so what should that ph be? once i transfer to hydroton I will have 1000watt Rating: 5
