Why not blow fan directly on plant?

Well if you have too much wind blowing on your plant it can disrupt your roots and stunt the growth. I have my fan blowing imdirectly, but enough so that the leaves and stem are gently swaying in the breeze

I tried that shit on 100 clones and left for the weekend came back and had a 100 dead clones FYI they were actual plants either way they died cause of the fan which was 4.5 feet away. I would just do it for 30 minutes on 30 minutes off now they i have that problem
haha yeah bad idea

U have to use ur own good judgement in each case. Blowing direct air on a plant that's a month old is ok. If its a seedling probably not. Althouth a weak stream of air is fine.
it does alot for strengthening stems and aleviating mold. Dont rely on what someone says...use common sense.

^I agree with all you guys, but have to add one warning....


....I've had this happen, and it took me a handful of grows to figure out. I run my humidity a little lower than alot of guys, and also used to run my temps quite high(around 85-90*), with a oscillating fan going constantly. Well, it took me forever to figure out why my plants on the outer edges would get "the claw", like a nitrogen overdose, even though I knew they weren't overfed. Then I thought it was something to do with the light being weaker around the edges...wrong.lol Finally, I realized that they were in the exact spot where the fan stopped, before changing direction, and as mentioned, they over-transpired(if that's a real word.lol), and ended up looking claw-like. It didn't effect all the strains, either, just the Crystal, which made it more confusing. Well, I moved the fan a little, and the problem has never come back. So, my only conclusion, is that it was indeed, the cause of the problem. Whoulda thunk it? :wink:
Same clawing with leaves here... Pointed away... Plants nice and healthy

It has been my experience that placing a fan directly blowing on the plants will cause wind burn to the leaves thus creating a stressed environment. In nature, yes the wind blows on the plants. However, this is not constant and the plants get a break from heavy winds. Yes, the wind will make the stem stronger but this is in response to stress. Think of it in a relational sense; a strong fan blowing on a small plant is probably the same stress that a tree would feel in a heavy storm. Yes, the tree handles it and it grows stronger over time (this is stronger due to stress), but the thunderstorm is not constant and the tree gets plenty of breaks in between the storms. You must have a fan in your grow area to keep the air moving but do not have it hitting the plants directly. Instead, have the fan blow onto the light or at a wall and let it reflect off the surface, moving around the room. The amount of time a plant has to flower is only 8-12 weeks, and if you stress it out for several weeks it gets used to such air movement, that is time you have lost from flower development.

Alot of times I see plants with discolored leafs. Resulting from a powerful fan blowing in tge same spot.
It happens to me also if I dont use oscilating fans.
Just watch here it happens all the times but people start hollering nute burn or defincey.

Makes sense. I chuckled at the hurricane thosuse i had my fan blowing them girls like they palm trees or something but couldnt tell if i was doing something wrong or right because it was like tug of war between forums and googling. So i tried to go by instinct. I feel now it would be better to just oscilate
You know.......,.......................Slap me silly turn me upside down and dump me in quicksand....Bol. I can assure you i will check the date next time. My goodness. Numb Scrote Sack. Man!!!

Yea it's an interesting one I have a stationary fan that I've been blowing throughout the stems and two pc fans that I can turn up or down blowing directly on the tops of the plants a lot of the plant that does not receive constant airflow seem to frost up quicker ......
