it can get worse, try having ur arm broken and you havnt smoked in two weeks then u hit the haze.. and next thing you know you cant feel your arm.. triipy shit
get some airfreshner and put the towel under teh door...
ps this will really not work , and to do it right u will need at least a grand or some good wood working skills... good luck
build a box, vent and scrub the air.. grow on
yes, those fans are not what your looking for .. google inline fans or centrfugial...vortex,can,etc... you want at least 200 cfm to vent a small grow space and light .. good luck soory i couldnt help to much
