you get a cool rep vote from me as soon as I post this! i also have a cheap-ass setup w/ a dehumidifiers exhaust keeping my (unheated) grow room at the proper temp, 75F, (and dryness), and am growing in IKEA garbage cans w/ drainage holes drilled in the bottom and a box window fan for my breeze. these are the perfect 5 gallon plastic cans. So I applaud anyone who creates kewl grow aids from household stuff! I didn't learn of 'scrog' when I started, so am curious if it really increases yield w/out sacfricing vertical room. Love that frame, good idea w/ the phone wires, just get a fan on them to help strengthen stems anyhow. especially with a screen holding up the leaves, you want good air circulation around the top once it starts to fill out.
Other than that, it looks great!
