lol bro chill out your setup sound fine 40 bucks is more than enouf to get you going... go out and buy some potting soil although go one that dousnt look like it came out of someones driveway... make sure you germinate your seeds b4 putting them in the ground i find paper towel method is the easiest... with your fan flouros dont put off much heat so you shouldnt need much ventalation leaving a fan on for a few hours a day should be fine.... unless your growing in a realy confined space you shouldnt need to worry about heat and crap a closet is more than enouf space for flouros with tap water depending on where you live you should leave it in a bottle or something with the lid off for a day or so before useing it other than that you should be fine man.... if you want some picks of plants grown under flouros ill show you mine just remember to keep them close to the lights .. about 4 centimetres other than that happy growing!!!
