hi everyone, this is my first post, although i have been reading through this board for the last couple weeks. I have just finished my frst grow outdoors with a very good yield, and after reading about scrog, it is a method I really would like to try. I have a large cabinet in my garage that I woul like to customize for this project.it is 4'wide 2' deep and about 8' tall. it is currenly divded right down the middle leaving me with 2 seperate compartment, 2' x 2' 8' tall. I have a general idea of my design but would like some input on which products I should get. on the left side of the cabinet I want to divide it into 3 sections, the top will be 2 x 2 x 4 tall. the middle will be 2 x 2 x 2, and so will the bottom. I want to mount a 250w hps at the very top for my flowering chamber. than at the top of the 2nd chamber I want to mount a 70 w hps for my mothers, and in the bottom will be a rubbermaid container for my reservoir. now I have a few ideas as far as ventilation but would like some opinions. I am planning on installing a 100cfm bathroom ceiling fan on top of the cabinet. and then installing dryer vents on the bottom sides. will this be sufficient or should i get a blower? i am also going to place a fan blowing across the top of the screen. now for the right side of the cabinet, I want to install 3 - 4 metal racks and make it into a drying closet. again I have questions on how much air flow i need for this? I am thinking of installing two 4" dryer vent at the bottom and then installing a 70cfm ehaust bathroom fan at the top. will this be sufficient for drying or should I re-think my setup? any help would be greatly appreciated, thanks
