If temps and humidity is good Do You Really Need a Fan on?

I have a 3 x 3 tent and a 600 with 2 to 300 cfm exhaust

I have always read that fans help make the stems grow stronger, but I wont to grow bud not strong stems. Will reducing the amount of time the fan is on help bud production. My humidity and temps are good without the fan I would like to know if anyone has any experience with this.

I have a oscillating fan on a 8 event timer to run 5 minuets every few hours.

Any thoughts?

a stronger more developed stem is better able to transport nutrients. in flowering air flow is critical to avoid bud mold/rot.

ALWAYS! The leaves absorb all the CO2 in a short period. Air must be moved to replace stale air. And yes, it also discourages mold and mildew. Remember you're re-creating mother nature. Outside there is always at least a little air movement.

^^^^ yes for all the reasons, you only need some air movement 24/7 but you do need it.

thanks guys, fans on

I find it difficult to believe that your temps in a 3x3 with a 600w and no ventilation are good. What are your temps?

bigger stems= bigger buds

Sorry Diaz, to explane a little better..

I have a carbon filter, air cooled hood and a 6 in inlinefan that is on 24/7, I was wondering if the fan blowing directly on the plants is really necessary if all is good with the environment in the tent.

The faster the leaves are able to flap back and forth the better the CO2 intake will be.
