2 fans better than 1?

in my small grow space [D x 1', W x 6', H x 6'] are 2 small circulating fans better than 1 there are 3 plants under a 250w hps, i have two bathroom 4" extractor fans just freestanding at floor level one at either end of narrow grow space, theres also a 4" inline extractor with carbon filter at highest point of room.

if one keep your crop moving, its enough, but two won't hurt. just don't make it windy

Depends entirely on teh fans in question and how they are functioning. If one is doing the job that needs to be done then one is all you need. If one fan is not creating sufficient air movement and circulation, then yes, it would make sense to have two.

yeah cause when i have just one going the plant at far end doesnt seem to get any movement, im just pointing them at plant pots like this

thanks scroglodyte you helped me out on that other problem as well not long ago, seem to be taken alot more out of the forum than putting in but im sure that'll change with time and experience.

Point them at the plants, not the pots. The pots are solid objects which do not let wind through them.

Yeah, I always heard to have the fans with the air circulating at the top of the plants.

i like to position the fan so it blows air at the wall then bounces of the wall towards the tops of the plants. i had it blowing at the plants before, and some of the plants closest to the fan got wind burn.

Air movement is critical. Too much though can cause problems. Depending on your humidity you can wick moisture out of the leaves if too aggressive. Smoke has it, have them pointing at a wall and let the circulation of the room do the work.

yeah thats why i aimed them at the pots being such a tight space i figured it would bounce around abit before affecting plants
