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.

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.

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
