hey guys i have one question. why should fans not be directly onto plants? i always read that they should circulate the room but not directly on them???

I'd be interested in seeing the answers this thread comes up with too. I see a lot of people, including me, put a fan on plants to help strengthen the trunk.

Fans can damage the leafs by them knocking into each other if they are too close and if the conditions are right they can cause wind burn although that is not very common.

I run an oscillating fan on low speed directly on my plants daily for like 4 hours, but during the lights off period I use a smaller fan to circulate air but it's not blowing directly on them. I don't think it would hurt the plants to leave air blowing on them directly 24/7 but I just didn't want to take the chance of it stressing them.

A circulating fan will help the trunk on the plant become strong.
Circulation makes for 'stress on- stress off' in the branches as it faces in nature with wind etc. and leads the plant to create more fibers in it's trunk structure. A heartier stem structure means better bud carrying stems.
The younger the plants the less they can support strong air flows.
A constant flow on the plant will cause stress and it will not build the same stem. probably be short and all stock and low bush.
I'm a noob too and have been reading like mad hehe.
I think the only bad question is the one not asked.
But do use google and the search tool here to search basic things this site has helped me tremendously so far :)

ok my opinion.........windburn from fans being placed to close to plants is more common than you think , stems do thicken from having a strong airflow, but buds certainly do not ....air circulation is important in all grow areas, however most inline exhaust fans are strong enough to give good circulation, air flow is good , just not directly at the plants...as for leaves banging together and damaging eachother....hmmm....maybe in a hurricane lol.......=) peace!

That's what people say....but I know plenty of growers who don't use fans and get monster buds. The fans effect on stressing the stems is either greatly over rated or has almost no effect on yield as far as I can tell.

kind of like science vs. nature..
No you don't need a strong stem because you can tie it off scrog and all
but I do think a little circulation helps all around in veg and flower but I am an admitted rookie..

light,water,grow medium and fresh air = good times .............. circulating cant be bad ......can it ? my mother plant stem is 3" thick and never been near a fan .......the mind ponders eh ....

well she is a momma and has never been asked to carry buds (1) and never stressed into flowering(2)
Age is the best way to grow a kickass plant but time parameters cause us to stress the plants at our leisure not theirs and in consequence small details during propagation like fanning plants to increase stem strength become helpfull.

sorry i should have said , shes a mother i re-grew and has been flowerd.... obvious reasons for doing this ..... etc

yes but a powerful ventalation injection causes a strong airflow =)
Ventilation can be circulation also but not vice-versa
My veg cab so far is good with just inline fan 4X4X3= 48 sq.' X 165 cfm fan to ducting to odor control and passive inlet but I am adding a 6" oscillating fan anyways.
