Veg. or flower?

Hello all,
I am a little new to growing and was wondering when would be the best time to have an oscillating fan hit your plants. Should you have a small fan in your veg room? or wait until the flowering stage when their stems develop a little more? Any input would be appreciated

A slight breeze during veg can help your plant build a stronger stem, and during flowering I've found that good air circulation is important to prevent mold...So yes during all stages of growth I'd say fans are a good idea. Now if you have temp. problems, say it gets a lot colder at night when the light is off, then the fan could be bad because it will make it seem even colder for the plant, but if your night temps are pretty warm then keep the fan going. Fans also help bring temperatures down when the light is on if you have heat problems.

Yes, that is my plan as well. Once my beans have sprouted and they are put into their final pots, I plan on turning on the fan. I may turn the fan off every once and a while for an hour or two. I may randomize it like nature.
