Ok Thanks for the tips so far. soaked and rinsed the livin hell outa my ton, im on the 3rd soak now and prob gonna do a 4th. im getting quite nervous as germination time aproaches. My setup is 5 net pots on the rubbermaid with airstones and a submersible pump feeding the pots, i have mylar glued to the tops of the rubbermaid, i plan to put germinated seeds in rr inside humidity dome with 4 four foot fluros for about a week then transplant to system, i will then start the 1000 watt hps, temp in room fluctuates between 80.4 and 82.5, humidity with lights on is 53%, i plan to run no nutes for 2 weeks and then add superthrive and foxfarm growbig, to keep water temps down i plan to use frozen bottles(no other choice) i plan to keep the water at a slow steady stream, i also have some no slime liquid called aqua sheild. im gonna try to grow the cheese and white widow. at flowering im going to switch to ff tigerbloom, my current tap water is 334 ppm (Upper peninsula water). i have 3 fans and just cant get that temp down any further,exhaust fan is running full blast. I do have a 400watt mh/hps but not sure if that will be enough light for for ten plants (2 rubbermaid totes 33g) in this room size? any tips advice or corrections would be most appreciated , sorry for rambling on, here a few pics

Thanks
