im new to MP and new to growing, please correct me if i break any rules. My growbox will have a 400hps/mh light and two 8'' inline duct fan at 500cfm, and its gonna be in the attic. my box is 2'Lx2'Wx4'H. anyway the only power outlet i have in the attic is the one my A/C is on, and its not too far from where my box gonna be, i was wondering if it's safe to use a heave duty extention cord, plug it in that outlet then use a surge protector (http://www.powersentry.com/products/100373.php) to run a 400watt hps/mh from HTGsupply.com and i have two 8in inline duct fan from (http://www.homedepot.com/prel80/HDUS...o.0& MID=9876). will this overload my outlet? will the surge protector circuit flip if its too much power or will i get some fire? please help me out.can someone tell me a safe way of doing this, or how to add another outlet in the attic that will b safe to run the item listed above. any response will b much appreciated.
