Fanning seedlings

So I want to start fanning my seedlings... they're just recovering from transplanting, so i figure now would be a good time to strengthen those stems so they can hold their nugs later.. what i was wondering, though, is how often you all fan at this stage? Its not necessarily for gas exchange, just for the sake of the stems....

do you leave a fan oscillating for 24/7 or go in intervals? does it really make a difference either way or the other?

THankS

i keep my fan on 24-7. just make sure there isnt to much wind speed. if possible, keep the fan about 5' away from the infants

i leave a fan on during lights on. you can have one on all the time but really isn't necessary during lights out. all you want is a gentle breeze on the plants. to use a fan, to strengthen stems, isn't something you want to do. put a tomato cage in place early on, or just use stakes.

i'm not happy unless all my foliage is shaking with a breeze. close-as-possible-lights and a fresh breeze makes for happy, happy plants!

word, i guess ill go for the 24/7
