noway to tell, well fans are for moving air, wich takes heat out, strenghthens stems, and gives the plants a better chance to process it. Dry, ty the main stems to a clothes hanger and hang it in a dry area for about 2 weeks or so, dark is recomended, but not neccesary. CUring, put buds in a sealed glass jar and open once a day for 2-5 min. 2 weeks minimum. Day by day, lights go on, lights go off. !8/6 for veg and 12/12 for flowering. Feed after the first 2 weeks with a low strength fert and water when the top inch of soil gets dry. Hope all this helps.
