Troll.

it'll move air around it..

are you take about an exhaust fan or an osculating fan?

it will fan your plant

Give the plant a blow job

Strengthens the plant so that it will be able to hold up large colas,no twine!

yea.

fuck your leaves up if your not careful

On my first grow myself, but I know that it strengthens the main stem so it can hold itself up under the weight of the buds. Got mine on a windowsill so I just use the wind for that

Ive never had fans noticeably strengthen. Even with several thousand cfm.
Wiggling and flexing is the only thing that really works
