    depends where you live if you live somewhere where its 32c right through the night then keep the fan on the lowest setting. but if its somewhere with a temp of 15c at night switch it off

    usually always...to help with the stalks strength n all...but make sure if you're using HIDs that when the lights go off, ur temps don't drop too much

    U shd really keep them on all the time as the leaves will use up the air around each leaf and if there is no air circulation, the leaf will get a small blanket of stale air around each leaf and this only takes a min or 2 for that stale blanket to form so always need circulation

    if u put the fan to blow directly in the plant an the air flow is strong u might get wind burn on the plant,in that case make the fan blow indirectly

    dont oscillating fans stop wind burn. If your worried about that tho, face the fan to the wall, as long as ur not growing in a warehouse and only in a small area

    Not at all get an osc. fan or make it hit the wall if its a small grow room. You will dry up ur plant if u have it on it constantly.

    i never have the faqn blowing directly on my plants. point the fan in a corner, a little sideways and a little up. it creates a big swirl around the room. if your leaves are just barely moving, thats plenty of air circulation. it will help control powdery mildew and also strengthen the stems. if you have a dense canopy, make sure your fans in a position to circulate the air down low, into, bewlow and around your canopy.

    if your plants are in a closet space and not an open room, crack the closet door and put the fan OUTSIDE of the closet, blowing gently from across the room in the direction of the door. you dont need the fan blowing directly on your plants. all you need is just enough air circulation to see the leaves barely move, thats enough to circulate the air. also, remeber if your growng with MH or HPS lights ( or any other HID system) that you ca actually make heat problems WORSE in your rom by running a fan. a metal halide lights put out as much or more heat than an electric heater,if you have several, your asking to cook your plants without proper ventilation. when the air passes around the lighting, it recirculates the heat put out by the bulbs instead of hanging around them and the ceiling down lower in the room at plant level. bad news.

    i also run my fans on a timer, hour on, 2 off.
