Well as my first run was a failure do to not planning properly would like to see if I can get help from everyone to get me going.. I bought 2 - 34 gallon totes with a 6 inch inline fan rated at 250 cfm.. I also am going to use a carbon filter. The new totes I bought are 28 7/8 x 19 1/8 x 21 which I am going to stack giving me 42" in height.. I'm planning to grow 1 lady at the time. I'm going to use a 6" passive 90 degrees air duct on the bottom left and the 6" inline fan as a exhaust which will be reduced to blow through my carbon filter.. I am using foil tape in the box to keep it reflective and light proof.. my first question is with 42" height in the box I'm using 6 cfls how high should I mount the lights??? Thanks in advance!!!
